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.

Space Junk – The Strangest Trash (Not) on the Planet
With all our problems down here on Earth most people don’t think about space junk very often, but there is more of it to think about than most people realize. An estimate 50,000 pieces exist that are large enough to do significant damage on collision with an operational space craft or satellite. Over 90% of the stuff we currently have in space is useless trash – with less than 10% being operational/useful.
Awesome: Solar Powered Bicycle Boat Design
Imagine a boat that coasts along almost silently and works completely on free energy. OK, well, almost free: when it is cloudy out you may have to pedal a bit to get it going. Still, you get to toss out the pricey gas costs associated with most water cruisers and relax in the sun when the weather is nice and pedal your way to shore when it isn’t.
Gasoline That Grows on Trees – Literally
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.
