The OneCAT is a compressed air powered vehicle. It is small and light, thus automatically gaining a great deal of fuel efficiency. It runs on 200 liter tanks of compressed air. The vehicle has an onboard compressor. Plugged into a normal electrical outlet, the compressor can recharge the tanks with high pressure air in 4 hours. Future plans include a system of high pressure compressors deployed in filling stations which can recharge the tanks in a couple of minutes.
The OneCAT could be a perfect solution for local urban travel. Since it is not electric, it avoids the need for big heavy batteries. The savings on weight will give it yet more fuel economy.
The near future of consistently high gasoline prices will mean that populations enjoying widespread usage of gas sippers like the OneCAT will escape the nightmare of the gas pump.
