Question

Hydrogen or normal fuel? (efficiency and cost, and why...)?

Answer 1

Hydrogen is one of the most efficient, non-polluting fuels on earth.  Combustions produces only water.  To produce hydrogen, you needs lots of electricity.  So, if the hydrogen were produced from renewable sources (such as solar, geothermal, hydroelectric, etc.), then hydrogen, hands down.  This would dramatically reduce pollution, have not CO2 emissions, and would make air much healthier.  It is difficult to determine if there would be a cost-savings with the price of gas fluctuating and solar panel technology improving hand-over-fist.

I hope this answers your question.

Answer 2

Use hydrogen and ethanol so that we arent dependant on the arab emrate (sp?)
