SMALL LOW COST HYBRID ELECTRIC CARS NEEDED

CliveS
At present only large companies who can write-off car expanses are using hybrid luxury cars to advertise themselves as environmentally friendly wealthy companies.

What we want is a small smart light weigh car with under 1000cc engine that can do 200 miles on open road and then switch to a small low power battery/motor that can do just around 10 miles inside the city boundaries. 

NOTE.  One standard 12 volt lead/acid battery 100 amp-hour contains 1kWhr of energy.  Small petrol engine is typically 35kW; so 3 batteries will give 3 kWhr which is just sufficient.  Or is it???

    Hydrogen gas cannot be liquefied at normal room temperatures and requires massive strong tanks to be stored as a gas.  Easiest way to store hydrogen is to combine it with a carbon atom and make a hydrocarbon liquid gas or fuel.

      However, when you burn hydrogen only with oxygen you get pure water and heat energy BUT with hydrocarbon fuel you also burn the carbon with oxygen and get carbon dioxide which is no problem in the countryside where it is absorbed by trees and vegetation but is a pollutant in cities. 

    So best of both worlds is a hybrid car running on hydrocarbon on motorways but capable of short distance trips in cities using electric batteries.
