Thats not a new thing... www.pneumobil.hu Peace!

If they were to just use coal and other fossil fuels to power the compressor we are still stuck with the issue or using non-renewable fuels. I think this is a great invention and thanks for this idea using a light bike is a much better idea than actually using a heavy steel go kart. - Derik Thu, 17 Dec 2009 11:23:18 +0100 http://www.ecogeek.org/automobiles/1549#comment-31727 I cant understand why anyone would be against this. (not realy air powered). The by product of Fossil fuels has so many harmful issues, air and water and earth pollution from releases from storage facilities. Not to mention the direct release from just burning the fuel. Hydrogen is many years away, maybe it will work. Electrical/battery needs years to get better, but very soon it too will be a plugged in system in the home. The first internal combustion engines were very small at first, this has big promise. - Bruce Sat, 24 Oct 2009 11:29:37 +0100 http://www.ecogeek.org/automobiles/1549#comment-30206 Look great. Do you have any video with your motorcycle? - Flower Russia Tue, 08 Sep 2009 11:56:51 +0100 http://www.ecogeek.org/automobiles/1549#comment-28756 very good keep it up and this is the future in evry mobile field and within 5years it will be all over the world!!! - vijay Thu, 23 Jul 2009 04:01:18 +0100 http://www.ecogeek.org/automobiles/1549#comment-28181 I've wanted to build something like this bike for a long time, but Jem Stansfield actually did it. I like the pedal-assist idea, I think more tanks can be added and a faring added to streamline the bike. I wonder if the most efficient air mtor is being used. The air could be stored in a central home tank filled at least halfway at night by a wind machine with gear or belt assist to push high pressure into the main tank. The main tank could be topped off automatically by a standard or rotary compressor. - Tom Miller Thu, 02 Jul 2009 14:57:41 +0100 http://www.ecogeek.org/automobiles/1549#comment-27097 I am pretty sure the quick refill is easily attained, even with a normal scuba style compressor. The solution? A much larger holding tank permanently connected to said compressor. If I was doing this, this would be the method I would use. Fill the big tank automatically any time it's pressure drops below a specified point. Refill of the vehicle tanks is accomplished by simply using a regulator and a release valve. In this manner refilling the vehicle tanks can literally be done in seconds. Some care would have to be taken to ensure that the tanks do not fill TOO quickly, or you stand the risk of an explosive rupture. The point is, the compressor is NOT filling the vehicle tanks directly. Fluid Dynamics 101. Pressure always seeks a balance. If the pressure at point A (in this case a large storage tank) is greater than the pressure at point B (the vehicle tanks) the air will naturally move from point A to to point B in order to balance the pressure. - Boaslad Thu, 21 May 2009 20:26:01 +0100 http://www.ecogeek.org/automobiles/1549#comment-27095 First off I'd like to say I love the bike idea. it's one I have been knocking around for years. It's nice to see I am not the only nut-job out there... Speaking of nut-jobs... I would love to just point something out if you really want to split hairs about whether or not this is actually a "green" idea. Consider this. There is NOTHING you can do, EVER, that is completely "green". For example do you plant you own garden? What about the fossil fuels that were used to mine the metal that the tools are made of? What about the fossils fuels that were used to transform the raw ore into a usable item that you can use? What about the fossil fuels that were used to harvest the plants that the seeds came from? What about the fossil fuels that were used to transport the tools and seeds to a store near you? What about the fossil fuels used by YOU to go to said store and purchase said items? What about the fossil fuels used to harvest the trees that were used to make the money that had to be transported to you so that you could make said purchase? While we are splitting hairs, let's split ALL of them. My point? The electric company is going to burn the coal ANYWAY, regardless of whether the [i]minority[/i] of us use or don't use it. Might as well put THEIR waste to OUR good use, and stop nitpicking over petty, minuscule, and quite honestly moot points. - Boaslad Thu, 21 May 2009 20:05:39 +0100 http://www.ecogeek.org/automobiles/1549#comment-26652 It was made into a hybrid that has pedals and a pump powered through pedaling in conjunction with the existing setup so that the riding can tap the tanks when he wants some rest? I know that overall, it would take more power but the idea of using the air uphill and pedaling downhill is tempting. Anyone think it's possible? - bak Sat, 09 May 2009 18:07:32 +0100 http://www.ecogeek.org/automobiles/1549#comment-25498 I missed this program on TV and i live in india.. i m a engineering student and working on a similar thing. if u can manage to pitch in some more details about this bike.. specially about that air motor like what torque is used to propel this bike it would help me a lot.. - kalivd Fri, 27 Mar 2009 09:14:52 +0100 http://www.ecogeek.org/automobiles/1549#comment-24810 It looks like his tanks are 9 liter 300 bar fiber carbon SCBA tanks. (87 cubic feet, 4500 psi). Bicycle pumps and compressors for tools aren't going to fill them. The stored energy in each tank is about 1.5 MJ, or 0.8 kilowatt-hours of energy. Since 300 bar/4500 psi compressors are only about 50 efficient, it will take about 1.6 kWhr to fill each of the two tanks. (1600 watts for two hours). The "refill in seconds" obviously is by tapping into a larger tank that is kept filled by the compressor. - Charlie Thu, 05 Mar 2009 08:57:53 +0100 http://www.ecogeek.org/automobiles/1549#comment-20434 Mount 2 tanks at a 45 degree angle as fairings and a 3rd tank above them horizontially. The 3 tanks can all be part of the fairing for better year round operation. Build in the headlight and turn signals. All this will help to streamiline it and increase it's range. Lots can be done be using a rear fairing for battery, storage, and motor and drive systems. Refine IT! - Paul Eckerson Thu, 30 Oct 2008 17:10:22 +0100 http://www.ecogeek.org/automobiles/1549#comment-18523 hook up a windmill to a compressor and off you go! im trying to do this myself but am trying to find a compressor that will allow the connection. - gerard Mon, 08 Sep 2008 09:43:53 +0100 http://www.ecogeek.org/automobiles/1549#comment-18480 please tell the detail about cost,capacity of air tank,efficiency in percentage,if any drawbacks mention it - sankarmahesh Sat, 06 Sep 2008 02:38:32 +0100 http://www.ecogeek.org/automobiles/1549#comment-18156 Could anyone inform me Jem Stansfield's e-mail address? today.is.a.gift@163.com - Chinese Student Thu, 28 Aug 2008 22:40:17 +0100 http://www.ecogeek.org/automobiles/1549#comment-18155 Could anyone inform me Jem Stansfield's e-mail address? - Chinese Student Thu, 28 Aug 2008 22:37:43 +0100 http://www.ecogeek.org/automobiles/1549#comment-17606 this was a very good concept for today as we all r fighting global warming...... I wanted to have information about the engine you used......plz rply for the same n details abt what kind of engine u used to make it possible - RAHUL Wed, 13 Aug 2008 00:35:21 +0100 http://www.ecogeek.org/automobiles/1549#comment-15912 The tanks could get compressed by somehow trapping the strong winds of a tornado. Then we could power the trailer parks for free. Its powered by compressed air dude. How the air gets compressed is none of your business really. The future is beautiful! - davidEdwinLewis Thu, 10 Jul 2008 14:02:24 +0100 http://www.ecogeek.org/automobiles/1549#comment-15781 Hi all, I would like to know the specifications ( configuration, bore, stroke, valves) of the air-engine that Jem used for his moped. Thanks. - Raghu Tue, 08 Jul 2008 01:50:57 +0100 http://www.ecogeek.org/automobiles/1549#comment-14774 Get over the "It runs on electricity thing". It uses air to power the vehicle, how the air gets there is another thing. Using your same theory, means that petrol cars also run on electricty, Because, without electricity, your petrol station couldn't "pump" your petrol into your car. SO, feel free to tell me how "Electrically pumping petrol into a car" or "electrically pumping Air into a car" is any differant? I don't see you crapping on about how Petrol cars are really powered by electricity.. - Craig Mon, 16 Jun 2008 07:01:57 +0100
