<VV> New engine possibilities

[jvhroberts at aol.com]

 A lot of this is conjecture anyway, and with all rapidly advancing technologies, what's difficult today may be commonplace tomorrow. Less than 10 years ago, rechargeable lithium batteries were merely a lab curiosity, now they're in nearly every portable electronic device. Including the Chevy Volt!!

Did you guys actually watch the video? The points you have brought up were

addressed.



1: re-pressure can be done at a "station", (of which there aren't any yet)

in a couple of minutes, or you plug in the car to use an onboard compressor

which takes several hours.

2: the tank is carbon fiber, so that there is no shrapnel or rocketing tank

in the event of catastrophe. It just cracks and releases the pressure -

probably blow you down if you're standing nearby.



To me these are not the questions that need to be answered, my questions

are:



1: does this tank of air contain more potential energy than a battery pack?

2: how efficient is the energy transfer - electric to pressure, then

pressure to motion? In other words, how much energy is wasted getting me to

my destination?

3: how much of the energy savings due to the vehicle being under 1000

pounds? there is a lot of legislation that would be required to make one of

those street-legal in the US.

4: and as Ron brought up - what is the longevity of the design? in this

market you won't sell a vehicle that doesn't last 100K.
