High mileage carburetors have been perfected. Other systems both hot and cold fuel vapor also work. Systems that mystify and preheat the fuel are effective as well. These all can be perhaps used together and improved but in all reality it is ancient technology. While in certain applications where fossil fuels are still used passing up gas stations can be a real blessing. Then again if we can produce more power using BG-nitrogen the sky is the limit.
WELCOME TO THE PERPETUAL AGE!!!
