i was looking at
http://www.theaircar.com and they are using compressed air in order to power a vehicle. it is a fairly simply concept but i am curious every one talks about using diesel generators and such in order to make a hybrid but why not use the same concept as the air car but using the air power to charge the system, batteries etc. yes would require more computer parts to regulate when it would kick in etc. but if could simplify a little why would it not work. if can recharge the new lithium batteries that quick charge when say at 75% power till able to recharge then if able to produce enough power both run car and recharge battery. or just recharge battery at faster pace then it is draining.
the inventor has a us patient for a generator built on air but is a huge version so many other parts and such for buildings so not really an option.
i am also curious of using 4 small dc brushless motors at each wheel instead of keeping the tranny and such. this would be a big weight loss to the car but more batteries. so maybe the same. i am looking for help. thank you
