A surprising one this time – We have suggested numerous bizarre replacements for fossil fuels over the years. Here’s yet ANOTHER suggestion for something other than gasoline to put in our cars: Watermelon juice. And if it doesn’t work in the car, it makes great moonshine!

The problem with watermelons is, just like corn, farmers produce too much, and blemished fruit is often left to rot in the fields. Brazil runs its vehicles on sugar, so maybe we can run ours on fructose.

To piss off petroleum providers – Urine-powered cars, homes and personal electronic devices could be available in six months. No, you won’t be pee into a battery: urine will be collected from cattle, just as it was collected from pregnant mares when hormone replacement therapy was being prescribed for post-menopausal women. Soon we’ll use cows for more than milk: just one of them can provide enough energy to supply hot water for 19 houses.

Everyone’s talking about biofuel for cars, but what about using it for jet planes? The seeds of a weed could cut jet fuel’s carbon emissions by 84%.

Engineer David Shonnard analyzed the carbon dioxide emissions of jet fuel made from camelina oil and says, “Camelina jet fuel exhibits one of the largest greenhouse gas emission reductions of any agricultural feedstock-derived biofuel I’ve ever seen.”

Camelina sativa originated in Europe and is a member of the mustard family, along with broccoli, cabbage and canola, and it thrives in the semi-arid conditions. “Unlike ethanol made from corn, it won’t compete with food crops,” says Shonnard. “It is almost an exact replacement for fossil fuel.”

Fuel from ice? How about fuel from algae?and the water it lives in!

The invention of an efficient system for splitting water into hydrogen and oxygen will be what shows us if hydrogen really does have the potential to be a clean, sustainable fuel. But manmade systems that exist today to do this are very inefficient and often require the use of additional chemicals. But anew method uses a simple chemical process powered by sunlight.
