The car.. that runs on AIR! that's right.. air.

by daniel_mad / March 28, 2006 7:42 AM PST

Forget about hybrids, bio-diesels, and mexican cooking oil. The new fuel is.. AIR! yupz, there's a video from the discovery channel with a new type of automotive vehicle, that runs on Air. It uses Air Compression to actually run the car, with carbon fiber air tanks and the only pollution is cold air, which can be used for the A/C.

check it out guys!

PIstons vs. Electric Motor
by MacHugger / March 28, 2006 8:15 AM PST

Pretty cool, though I don't understand why the need for pistons. Surely they can come up with a more quiet and energy efficient delivery of the power generated by the compressed air to the drivetrain than that. Why not just develop some system that uses the compressed air to spin a device that is essentially an electric motor and then just use the electricity from that to spin the wheels?

I also hope they are using the brakes to somehow recompress the air so as to recover at least a portion of what is spent on acceleration. Again, if they were using an electric motor for the propulsion, the energy regained from braking could be fed back into the system.

What happens if...
by roberpic / March 28, 2006 11:10 AM PST

I'd hate to think of what happens if that air tank gets punctured. 200 L of air at ~4000 PSI. That's a LOT of air at a VERY, VERY high PSI; and on a super-lightweight car, no less.

Not really

This car uses air compression to STORE energy, but air is not the "fuel". The energy to compress the air in the first place comes from electricity. Which means that whether the car has zero emissions depends entirely on how the electricity is generated.

In France, this car probably is emission-free, because France uses nuclear power.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
