Hmmm... I think I'll stick to Petrol until they finalise Hydrogen Fuel Cells.
Now that's cooling!
No electronic bits - just pre-cooled Hydrogen in Liquid Form (<40 Kelvin) then kept in a container of Millions of Layers of Fibreglass with a Vacuum between each gap. Great stuff. Not good for cooling - but good for keeping temperature in, be it hot or cold.
