There is talk of a “hydrogen economy.” Australia’s prime minister, desperate to distract from his government’s failures, has promised to put lots of money into it in the (completely unlikely) event of being re-elected.

Lloyd Alter has calculated how many solar panels it would take to fill a car with hydrogen. He demonstrates the ridiculousness of the idea.
His short essay is well worth a read.
