Who dreams up a car that runs on wood or coffee grounds or a way to turn road traffic into energy? Technology is always unpredictable and no one knows for sure what the future holds. Some of these ideas are brilliant and some are bizarre but at least these folks are thinking way outside of the box. The truck above, for example, runs on a strange combination of vegetable oil and ammonia.
Let’s face it, trying to solve a big problem in one quick step rarely works out, particularly when the problem is global and touches on virtually all kinds of transporation. Too many alternative energy concept vehicles try too hard to rely on a single source of energy. Electric cars need frequent recharges and solar-powered vehicles of course need the sun. These three vehicles are a worthy stop-gap measure as the world slowly learns to rely less and less on conventional fuel sources and turns more and more to renewable energy.
Well, not gasoline per say but something strangely close. With minimal filtering and no refining these amazing trees produce fuel for up to 70 years and and at a rate of 1 barrel per 4 trees per year. After extraction, the fuel must be used within a few months but can be put almost directly to work in a diesel engine. However, even if the fuel is left for too long it changes into another form of oil that fetches a fairly high market price as a medicinal substance.
With elections looming ever closer in the US, more and more politicians are trying to establish strong positions in the political ecosphere. Of course in many regards the US is still a ways behind the rest of the world in terms of environmental policy. However, other surprising giants like China are even jumping into the fray, suggesting that even the world’s more reluctantly green super-powers are getting into the game.
