What's New

Electric PPG Developments | See Worldwide Efforts Underway

Batteries, Motors, Other Aircraft

It is the holy grail for many talented designers and craftsman who dream of flight: a practical electric powered paraglider. We are fortunate to have such people. They will hopefully soon lift gasless flight from a dream into reality. Whenever new information becomes available, it will be added here. Thanks to those who share their knowledge of these developments. Developments for E-Pac's promising effort are found here.

Website & Industry Developments

There's a chance for an electric PPG to be at Beach Blast 2016. Stay tuned.

Website & Industry Developments

If you see this it's a milestone for several reasons. #1 is that it means we're actively working on upgrading our web design tool. This is the first step. #2 it means that FootFlyer.com's upgrade is not far behind. One major motivator is to make it more mobile friendly but still be quick and easy to use. Mind you, "not far" is a slippery term that's frame dependent. If we're talking geologic time, that could mean a million years. I don't think it will be that far, of course, but many other projects vie for time including a new instructor book that we're working on.

Hopefully there will be developments in electric flying but being realistic we must realize that they'll be incremental. Right now electrics can go maybe 15 minutes of really hard flying or 40 minutes of cruising on a reasonably efficient wing for pilots up to about 200 pounds. You'll see longer times advertised but try to get independent verification. Look at the weight, too. Yeah, you might get more than 40 minutes but only with a lot of battery and that means heavy. Right now BlackHawk Paramotors is the only company selling an electric and, at last word, they may have stopped.

Skywalk eParamotor for Free Flyers

Thanks to Matt Unger for the update.

It looks like Skywalk has released info on their new electric motor, the e-Walk, as seen at their website http://www.e-walk.org/. It's intended to be used as an 'assist' motor to get a free flyer up high enough to soar. Endurance is not long enough to make it a practical traditional PPG.

Pricing is 8900 Euro, about $12,400 USD right now.

Home Made Mostly Off-The-Shelf eParamotor

Gareth Houghton has now test flown his electric launch-assist paramotor that he intends to be used primarily for taking off to go soaring. You can more information on his website here. He also has a YouTube video here.

Skynch is Back

After a several-year hiatus, the Skynch self-towing system is back. This device allows one paraglider pilot to use a radio controlled signal to operate a tow winch on the ground. This is intended for free flight pilots who are experienced with towing and, for them, this would be a great self-launching tool.

More info at their website www.Skynch.com.

Note: Towing is extremely risky to the uninitiated, well beyond appearances. This is due to the dynamics of being hooked to a line where any offset causes more offset tendency. Expect serious injury or death if conducted without proper training.

Tandem Electric
06/26/2010 Twofer

Elektro has started selling a twin paramotor. Check out more here.

03/18/2010 New Goodies

This from Ela Bernatt in Poland:

We are pleased to inform you in Poland first flights of 2 person electric powered paragilder - trike type (pgg) took place. The machine, made in Poland, can fly for up to 1 hour with 1 person aboard. More details are at www.eledriveco.eu which has technical data and video from some of the flights.

03/18/2010 New Goodies

There has been some activity in the world of electrics and we're trying to dig up more.

There is an alternative fuel event, the Eco Ultralight Marathon, planed for July in Vichy, France that should be interesting. It's a competition and exhibition with many companies, including Yuneec International, showing off their latest.

Footflyer.com has details on several new Electric PPG's that will hopefully see the light of production and become more available. We know there's interest because emails come in asking to buy one here. Unfortunately, we don't sell them nor do we plan to in the future—just report on them.

New Blood
10/05/2009 Information Update

Razebuss is starting production on a new launch-to-soar electric that now sports a cage. And a new entrant, André Lecoultre, has created a pod-like electric paramotor that's made for foot launching, another in the effort to mate electric power with paraglider soaring.

E-Pac Flies at Oshkosh
08/17/2009 Information Update

Yuneec made its U.S. dubut at the world's largest airshow, Oshkosh's Airventure.set. They set up two booths, one in the main area and another in the ultralight area. They brought two electric paramotors and a hands-on display that allowed would-be flyers to play with the controllers and see how everything worked.

Eric Dufour and Jeff Goin flew the paramotors during separate sessions. Yuneec said they planned on having machines available by the beginning of summer 2010. A more complete write up will be included in Ultraflight Magazine and FootFlyer.com but the gist was that it has about 20 minutes of "playing around" time and about 35 minutes of flying around at cruise on a reasonably efficient wing. Here are the specs. The machine and its operation are extremely refined and look very nice.

Electric Airplane Flies & Heads For Oshkosh
06/25/2009 Information Update

We've already mentioned that Yuneec is bringing their ePac electric paramotor to Oshkosh, but now they have test flown, crated and shipped their e-430 electric airplane for an appearance at Oshkosh. So the electric revolution is accelerating on various fronts. Success in any electric aeronautical endeavor will only hasten success in our little niche. Oshkosh will be the place to see it all.

On Saturday at 11:00am, I (Jeff Goin) will be doing my annual presentation on paramotors in Oshkosh's Ultralight Area. It's intended for other ultralight pilots who may be interested our sport but, this year,  we will hopefully have one of the electric motors on hand and also answer questions about it. I'll try to get one of the manufacturer reps to be there for questions and I will talk about flying the craft.

Electric Miniplane?
06/15/2009 Information Update

Miniplane was showing the beginnings of an electric paramotor. They say it will be at least 6 months before everything has gelled to a flyable model. Electric guru Mateo is helping match industrial quality electronics to the lightweight desire of pilots.

Yuneec Electric Paramotor To Visit Oshkosh
/15/2009 Information Update

This is an exciting development. London-based Yuneec International plans to bring their production paramotor to the U.S. during OSHKosh's huge airshow starting July 27. They have made a number of changes, improvements and are reporting that production has begun in China. We hope to get details soon on availability and pricing.

They are making the motor available for review and some test flying, probably to high level PPG 2 or PPG 3 pilots. The motor will be shown in their ultralight display area while an electric aircraft will be displayed in the general area.

First Ever Electric Paramotor Goes On Sale
/15/2009 Information Update

Fresh Breeze has announced a new Electric Paramotor that is available for sale. The German maker has paired up with Swing to produce and sell the machines. Their brochure was only in German but some of the specs were clear.  The sportix frame unit spins a a 130 cm prop through a 10kW electric motor with an all-up weight of 33kg (72 lbs). It should fly a 78 kg (170 lb) pilot for 23 minutes.

It won't be cheap but being first never is. They say it will cost €6990 which would be around $10,000US before shipping. Fresh Breeze doesn't currently have any plans to bring one to the U.S. until they get an order. As soon as an opportunity arrives, we'll do a test flight and report on it.

Yuneec Update
02/12/2009 Information Update

Yuneec International has been busy. Although they didn't make it to Paratoys as planned, they plan to have 4 machines go through their production process in the next month. We'll have updates as they come in.

New Drivetrain & Organization
02/11/2009 Information Update

The company Electravia has announced they are offering electric drivetrains for paramotors and other ultralights. They have reportedly flown it on an airplane, a trike and a motorglider for our customers. See our website www.electravia.fr for more information.

They say they can supply a global electrical solution (battery, controller, motor and propeller) for many applications but, until now, it was too heavy for all except PPG carts.

They have created an association, APAME (www.apame.eu), dedicated to electrical motorization fans. They want to help APAME members in their projects though free access of our premises and experience by offering a discount when buying electrical components.

For more information contact Anne Lavrand.

Moving Ahead
11/20/2008 Information Update

There hasn't been a lot of news lately but efforts are still underway. After an exchange with Yuneec International's Clive Coote, he assured us that they continue to work on perfecting their product, a product that has seen extensive test flights. They have made a number of improvements and continue to work towards an affordable, producible version. A new web presence suggests that they are closer yet.

We have also seen some prototypes demonstrated, at least on test stands, that will hopefully also become viable products for their builders. It's easy to brush off the apparent lack of progress to economic woes, and indeed that's possible, but for the employed (over 94% of us)a desire remains for quieter, gasless rides into the sky.

Fresh Breeze Announces Drive Train Partnership
07/09/2008 Information Update | More on Fresh Breeze

Fresh Breeze has partnered with paraglider manufacturer, Swing, to create an Electric PPG Package. Dr.Werner Eck and Jochen Geiger have entered into a long-term agreement with SWING Gmbh about integrating our their equipment into a state-of-the art electric drive system. FRESH BREEZE will take over the drive specific design and fabrication the design pair of Eck and Geiger will deliver the drive, which consists of battery/charger, motor. controller, propeller and drive management system.

German DHV and DULV will cooperate to do the regulation work for new EPPG class.

Fresh Breeze Electric
06/25/2008 Information Update | More on Fresh Breeze

Fresh Breeze is busily tweaking their drive train. At last check they were planning on offering it to other manufacturers but, for the moment, are testing it on their low hook-in single-hoop model.

Progress at Yuneec International
06/18/2008 Meeting with Clive Coote | More on Yuneec

Eric Dufour and others were flown to China in order to visit and test fly the ePAC electric paramotor. Eric reports that he was impressed with their factory and production capability. This company is already a heavy hitter in large electric radio control models and manufacturers highly complicated and successful products. They do it all from design to manufacture. That same expertise will serve them well in production of Electric Paramotors.

Jeff Goin and Phil Russman met with Clive Coote to see what the latest was and they are obviously close to production. The test units have been holding up and they plan to have several at Basse Ham. We'll report on that here, too.

They're production model has the same battery pack that I test flew (www.FootFlyer.com) in early 2008 plus a plug-in accommodation for an additional pack.

Electric PPG Competition At Basse Ham
04/18/2008 World's largest paramotor event showcases ePPG

The Basse Ham paramotor convention in France will be featuring an electric PPG demonstration and endurance competition. We've been told of at least two companies that plan on showing off their wares and expect a total of 4. The biennial event runs June 27 - 29, 2008.

Yuneec Test Flights
01/12/2007 Test Flights In China

Yuneec International has sent 3 pilots and 3 production prototypes for testing in southern China. If testing goes well they plan to start production in time for the first products to be at the U.S. PPG Convention.

Information on their efforts here.

New Electric Flown
12/18/2007 Neil Andrew of England Flies Design

Neil Andrew has flown an Electric PPG that he may be marketing. The video claims 16 minutes flown with 30 minutes projected as available. Weight is listed at just under 20kg (44 lb) including battery. Here are details and video.

Testing of ePPG Offered by Yuneec
12/17/2007 Plans to let independent review of Electric Paramotor

Clive Coote of Yuneec International has offered to let us test fly their electric paramotor during or, more likely, prior to Sun-N-Fun. Jeff Goin will do a review in the vein of other paramotor reviews plus areas unique to electric.

Aspects of interest are safety, throttle response, smoothness, and linearity, behavior changes with diminishing battery capacity, longevity, weight, comfort, heat generation of the battery pack and charging convenience. More details here.

Yuneec International
12/11/2007 Specs Issued For Electric Paramotor

Yuneec International continues to work towards a production release of Spring 2008. They have been test flying machines and now have issued specifications.

Electric Paraglider For Soaring
09/26/2007 Razeebuss Air Lab

Razeebuss Air Lab has apparently test flown an electric paramotor intended as a self launch free flight rig. It is a very nicely manufactured machine with what appears to be excellent fit and finish judging only from the pictures.

The prototype is equipped with a folding prop for better soaring efficiency (much lower drag) and looks like it tilts when in free flight to further reduce drag. Obviously, having no no cage would an incredibly dangerous way to fly given that most serious injuries in paramotoring happen after body contact with a spinning prop. But in their case

That risk would be an easy fix, of course, and would make the unit more viable for the masses at some expense in drag. We hope to hear more about it as they develop it further. This machine is not designed for the paramotor masses as much as it is for paragliding pilots looking for another way aloft. Hopefully the paramotor style unit will be forthcoming.

Lithium Sulfur Batteries
09/15/2007 A New, Lighter, Cheaper Battery Source?

In an article posted on WiseGeek.com, a new form of battery is gaining ground to improve power at less weight in rechargeable devices. Besides weighing less per kilowatt-hour than lithium ion, they are cheaper and easier to dispose of.

EEstor Says Something
09/15/2007 PR Response

According to a response to queries about delayed delivery, Catherine Scrimgeour offers the following:

There has been no official delay communicated directly to ZENN Motor Company.  This particular is in fact misleading in its story title. EEStor is quoted as stating that the EESU is on schedule for delivery to ZMC within the next ten months.  That is not to say that they won't deliver before then - merely announcing the possibility that additional time may be required in the commercialization phase - not development time of the ultracapacitor.

The next milestone involves permittivity testing and no official 'due date' has been announced.

Please feel free to contact me should you have any additional questions or concerns.

Fax: 416.535.4043

ElectricPPG comments: Permittivity is an indirect measure if the capacitors capacitance. Hopefully they mean that the testing is required on the production versions because, presumably, the company already has a prototype. This technology, if their claims hold true, would be utterly revolutionary. Of course we've heard outlandish claims before so we'll see but there are some heavy hitters aligned with EEstor so hopes are higher than they would otherwise be.

China Company Enters the Fray, Hoping to Mass Produce
06/10/2007 Press Release

We've received a press release from a company in Shanghai that has apparently put some bright young minds to work on perfecting their planned mass-produced electric PPG. It has been flown by one of their competition pilots, Mr. Zhang, who gave a favorable report. Here is the press release and pictures.

German Electric Competition Completed
05/24/2007 update, thanks to Matt Unger

The Electric PPG competition in Germany has completed. Our hat is off to these folks for trying to inspire and promote innovation in this field. Here is a translation, courtesy of Stefan Obenauer, of the press release from the event. The original German site is here.

Ceramic Power Source Doubles Power
04/30/2007 update, thanks to Mike Macphereson

According to an article on CNN Money, the company EEStor has come up with an energy storage solution that would all electrically powered vehicles. It is reported to have 2 times the energy density of Lithium Ion at about 20% of the cost making it most appropriate for use in autos but hopefully, eventually, for electric paramotors. Another article on Green Car Congress says the company has completed testing critical aspects of their production line.

Of course we are all skeptical of wild claims and dates but this well heeled effort seems to enjoy broad respect in electric car circles. The company claims the materials don't degrade, charge in minutes and will propel a small, but standard sub-compact car 500 miles on $9 worth of electricity. We can only drool over what such energy density would do for a paramotor.

They are currently very secretive about the project but, having filed a patent, laid open the basic construction method. One electric car company plans to start using their electric storage devices in 2008.

Fresh Breeze / Helix
04/28/2007 update

Fresh Breeze developer Markus Müller is working with Helix Props has reportedly flown a 38 minute flight with the pictured electric paramotor. Although not confirmed, that would make it the longest continuous flight on an electric paramotor. Pictures courtesy Fresh Breeze.

We applaud his willingness to share information with the rest of the community working toward this end.

Update on Electric Powered Paraglider (Electric Paramotor) For Sale
03/31/2007 update

Dell Schanze, when asked via telephone, offered a little more about his new electric paramotor. When asked if he would be willing to let me review it he said it was not ready for that yet, preferring to keep mum on details of battery types, motor, redrive and most other design elements. He said that patents have or will be filed. He hopes to have video up soon You Tube showing the machine in flight.

Here is what he was willing to share:

The project is being funded by Dell Schanze and is not part of Revolution PPG as we originally reported although they do work together and it is being mounted on a Revolution frame.

It spins a 51" 3-blade Simonini prop at 2350 RPM at an elevation of about 2000 feet. The RPM is higher, as you would expect, at their higher Utah elevation although the thinner air produces less thrust.

Weight with the full 50 pound battery pack is about 80 pounds on a large Flat Top frame. That is equivalent to the same fully-fueled Simonini powered model.

There is currently one prototype flying and it has been thrust tested in Arizona and Utah. They also tested a 43" prop unit at 130 pounds of thrust although duration was not mentioned.

It uses the same throttle as on a Flattop where the user must be holding a grip in order for the throttle to activate the motor. There is also a master switch, like on the their gas model, that must be one before the prop will spin.

He offered that if someone orders and pays for the unit today he should get a finished, polished product meeting the advertised specifications in 8 to 10 weeks. If it doesn't meet those specifications the buyer would get a full refund.


He preferred to to publicize other details on redrive, motor or controller. As more information comes available and other pilots report on its flight characteristics, they'll be reported here.

First Electric Powered Paraglider For Sale?
03/30/2007 update

Dell Schanze is offering an electric paramotor for sale. He claims it to have a flight time of 1.5 hours at cruise power, 145 pounds max thrust and a weight of about 80 pounds which includes batteries. If true, that would be impressive. Earlier conversations with Dell Schanze indicated that they were testing with Lithium Ion batteries as opposed to Lithium Polymer but we do not know what was included on this model.

The price is high as can be expected for any leading edge product, at $16,900 for the complete system with charger but then that's to be expected. It'll cost.

If true, this could portend a new chapter in the evolution of electric powered paragliding and powered paragliding in general.

As soon as we get more news, especially independent verification, we'll let you know.

British Team Goes Public
03/13/2007 update

A British team led by Paul Hallatt has announced some of their progress in developing the rudiments to a commercially viable electric paramotor. They plan on flying a tandem PPG and trike (PPC) within the next month. Information on all their efforts will be tallied on their ElectricPPG.com development page.

Skynch Development Halted
03/08/2007 update

We are sorry to report that development of the Skynch self-towing system has been halted, at least temporarily, as they seek out investors. Apparently the first test flight did not go right when the unit burned out halfway through the climb. That destroyed a lot of expensive equipment and they are regrouping. They reported 100 orders for the unit if it could met design specifications.

Electric Paramotor Competition May 14 to 19
03/08/2007 update

The ElectricPPG yahoo group and MarksParaglidingPages have reported an electric paramotor competition in Crawinkel, Germany May 14 to 19. Besides being for electric powered paraglider units only, we have no details about requirements, tasks and judging. It is purportedly being organized by the DULV (German Ultralight organization) at the encouragement of Werner Eck, who has built his own working paramotor (see video below).

Helix propellers is reported to be putting money into the competition. An " X-prize" for electric PPG? That would be a wonderful development. There are teams working on this process around the world, many in confidentiality, but this effort could help share ideas to spur innovation. 

When we get confirmation and details of the competition, we'll post it here. 

15 Minutes on 4 Pounds of Batteries
02/24/2007 update

One development group, who asked not to be identified yet, has told us that they have achieved 60 pounds of thrust for 15 minutes using 4 pounds of batteries. The significance of this is for training. An average pilot can be kept aloft on an average glider (DHV 1-2) with that much thrust.

This also bodes well for use in training since pilots can be introduced to the motor weight gradually. Another significant aspect of it is that it was done using lithium ion batteries which are reportedly more stable than lithium polymers. The company is holding off making any announcements until they are ready to actually market something. 

Csaba Electric Paramotor
01/25/2007 update

Csaba Lemak is planning to bring his Electric PPG to the April 2007 US National Convention. Hopefully we'll get to fly it and offer a flight report. He says he continues to work on various aspects of the project.

Skynch Electric Self Towing
01/19/2007 update

The first news this year on electric foot flying comes from John Irving who has been developing the Skynch (pronounce the "sk" like in sky and inch like the unit) for self towing. They have a working prototype now and will have a video up soon on their website showing it work in the lab. 

They've solved some problems with the starting force of their brushless D.C. motors using a throttle style potentiometer.

This pulls the pilot instead of pushing and we look forward to seeing the details on how it will work out in flight. They have a nicely developed throttle that is shown here and the machine's inner works are here.

Helix Electric Paramotor
12/29/2006 update

Richard Krüger-Sprengle of Germany has been working on another approach to the electric paramotor, going for extreme propeller efficiency to make up for the lack for battery power. Instead of using the higher-capacity lithium polymer technology adopted heavily in the R/C community, he is pairing well-established Lithium Ion batteries to a 70 inch prop.

According to the helix-propeller website, he has been able to achieve flight time of over 15 minutes on his 31.6 kg (70 lbs) machine. The 35 Ah batteries weigh 15 kg (33 lbs) and take 2 hours to be fully charged from a depleted state.

Richard is working with other teams who are developing electric paramotors and hopes to establish a yeary meeting on the topic starting with the German Paramotor Championship in Krahwinkel. Complete specs and other information is available here.

Looking for Development Partner
10/29/2006 update

Belgium resident Koen Van de Kerckhove is neither an electrician nor an engineer but he is a visionary who dreams of electric propelled lofts in a soaring craft. And he has the means to pursue it. What he wants to do is motor up for soaring flights—the Electric PPG powerplant would do just fine. His craft of choice is a  rigid frame hang glider and he's hoping for a powerplant that weighs up to 40 pounds with at least 15 horsepower that will propel a 300 pound craft (pilot and hang glider) to 1000 feet.

He would like to see this project be as "open source" as the developers are willing, including making the plans available on the internet. Universities may like this as a thesis project and Koen is willing to work with them. 

His business is a machine shop, including CNC equipment, so he could produce some necessary parts. Impotantly, he is willing to invest money in it. If you are interested in working with Koen, email nestofdragons@hotmail.com, join his Yahoo Group, or snail mail Koen Van de Kerckhove, Jeroen Boschlaan 16, 2840 Rumst, Belgium.

Plettenberg Motor
10/29/2006 update

Marc Whitehead sent us information on the Plettenberg Predator Motor, a likely candidate for a successful PPG implementation. He also put some files in the ElectricPPG yahoo group and would be glad to discuss it there.

Salt Lake City
10/27/2006 update

According to a Yahoo BBS post, Dell Schanze and Bill Heaner are working on an Electric project although no details have been released. Bill Heaner of Revolution PPG designed and builds the FlatTop paramotor, a machine based on the Walkerjet. 

What's New In Europe
10/14/2006 Jeff Goin

It's huge and we don't know whether it has flown or not. This prototype electric paramotor was made by the German propeller manufacturer Helix and was on display at the 2006 Coupe Icare in St. Hilaire, France. The data sheet says that it uses Lithium Ion batteries which are well proven and relatively inexpensive type but have much less power (amp-hours) than Lithium Polymer batteries of the same weight. This unit was built on a heavily modified Fresh Breeze Frame.

Helix01.JPG (156403 bytes)Helix02.JPG (215276 bytes)Helix03.JPG (203087 bytes)Helix04.JPG (85163 bytes)

It appears that they are maximizing efficiency through use of a much larger propeller (70") and reducing drag by having fewer cage lines, a risky trade-off made only for the prototype. Plus, we don't know if they may include more protective cage lines during flight testing.

Thanks to Javier from Aerolight for providing this information. 

New Technologies Probed By innovator Csaba Lemak
09/29/2006 Jeff Goin

Some new technologies have come to the attention of Csaba Lemak as he continues towards a production capable paramotor. He is working with a professor from the Czech republic who is tasking his students with building some technologies (controller and motor) that will work well with a 47 inch propeller. He has been testing numerous props supplied by Richard of Helix propeller and has improved efficiency with one particular 47" model. 

www.rc-unionen.dk_nytforum_uploads_9302_2006918173952_Aspach 2006 1.JPG (54283 bytes)Mr. Lemak is also considering use of the RS-LRK-MOTEREN Outrunner motor about to be released in Germany which puts out 20 Kw (good for about 16 hp) at only 7 pounds of weight. Plus, he is looking at a battery technology from South Korea that has 70 amp hour batteries that, in a pack of 14, would power an 18 hp motor for 40 minutes of flight time at flight weight of 26 Kg (57 pounds). That is using his current technology electric paramotor.

He has been flying his electric machine consistently and wowed a local R/C club with its performance. This motor will be at the Albuquerque fly-in on Friday, Oct 6.

The best developments continue to come from the Radio Controlled airplane community although Csaba is working with others to solve some of our unique high-power requirements. The Lithium Polymer batteries that have taken over electric powered models have about twice the capacity at about half the weight of comparable NiCad or NiMH packs. 

He tells us of a group in Europe that is making an electric paramotor using a brushed golf cart motor that weighs about 7 Kg more than the one he is using but is more readily available. It uses the less expensive and heavier Lithium Ion batteries. We have no word on whether this machine has flown yet. If anyone has any information on that effort, please let us know.

Electric PPG To Fly At Albuquerque
09/27/2006 Jeff Goin

Csaba Lemak, builder of the first practical electric paramotor, is bringing his creation to the Albuquerque fly-in Oct starting next week. We'll have more details when they become available. This motor has flown over 30 minutes on one charge at a weight of under 50 pounds.

New Ceramic Power Source
09/26/2006 Submitted by Rob Catto

According to CNN Money.com (Sept 20, 2006), the company EEStor has received a patent on a new power storage system. The technology is not a chemical battery but rather uses ceramics and is said to pack dramatically more power than anything yet developed, presumably for the same weight. The company is going after automotive applications due to the obviously huge market. Our hope is that we eventually would benefit from the efficiencies of mass production. 

EEstore, based in Cedar Park, Texas, is mum on details as work continues on perfecting the product. They have not disclosed weights but the inference is strong, claiming that an electric sedan using their product would be able to drive 500 miles on a charge and be able to recharge in 5 minutes. Of course getting a plug-in site that can dispense that type of current will be quite a challenge.

Ernie Van Drongelen, Holland—09/24/2006
09/24/2006 Submitted by Ernie

A larger collection of electric PPG hopefuls has probably never been presented than those submitted by Ernie. We appreciate his sharing. Yes, they look bizarre and some seem hard to imagine in flight. One looks like the user would certainly give up an arm in search of success. But we applaud the effort! He has met with success using 2 direct-drive brushless motors with counter-rotating props. You can see more at www.andromeda.mysites.nl.

Most of us want quiet powered paragliding without the fuel and mixing and mechanical mess that seems endemic with the gas powered machines that are currently best suited to our application. Batteries the only way to store electricity and, in fact, electricity isn't the only alternative energy source. One interesting alternative is air power. We've received news of air powered motors using compressed air for energy storage. Fuel cells are now appearing in various applications.

2007-06-06 (thanks to Rob Catto) Here is a promising technique that further brings fuel cells closer to reality.

2007-05-30 (thanks to Jerry Foisel) A fellow is working on an air powered rotary engine. Similar projects are underway using more conventional piston engines. They use compressed air for storage which represents much of their weight although lightweight high strength composites have brought that weight down.

2007-06-03 (thanks to Gerard Farell-Baril) This fuel cell technology promises to advance the status quo. Although too large at present, scale is only a matter of time unless better paradigms crop up.
