I have been following this for quite a while even before MDI has been taken over by tata motors. It seems that we might see the first air cars pretty soon in India. The specs are really amazing especially considering the cheap refills and pretty much the freedom of using w/e energy you like to power a compressor at home.
The temperature of the clean air expelled by the exhaust pipe is between 0-15 degrees below zero, which makes it suitable for use by the internal air conditioning system with no need for gases or loss of power.
What a bonus !!
Wow, if that car would be available here for this price, I would immediately buy one...
About the air conditioning feature. Sure if you live in a hot country like india, this is a benefit. Here where I live, the warmth of a conventional gaz motor is a benefit...
