running vehicles by batteries nowadays are welcome by most economic countries both for emission free as well as cost effective.
i suggest to run all the vehicles from a small cycle to big car and truck should run on mini sized batteries like li-in, li-mhd, and they should be charged by some other fuel mechanism voltage (pulsating dc)generation. so that the vehicle should go for a long distance for an economic amount of fuel. but includes hybrid power that we are going to change once in an year or two. i want to make petrol pumped voltage generator in miniature size to charge the batteries which is used to run cycles, motor bikes, small trucks,car, van etc.it may be useful to keep our earth green.

Chrysler during the 1960's demonstrated a car that would run on almost any liquid that contained some hydrocarbons.........motor oil, hair tonic, perfume, cooking oil, terpintine, etc........it had a turbine for an engine........but it quietly died........i guess because of big oil............

it would be fantastic if the on-board computer could analize the fuel in the tank and adjust the engine controls to operate efficently on that fuel...........naturally there would be only certain fuels that thevehicle could use.......but it would make refuling a lot easier if one could have choices while driving to be able to fill up witrh what's available.
