Sustainable Transit
Vehicles that draw their energy from green sources have created an exciting new frontier in the travel industry! At least, that’s what most people think. When it comes to boats, though, alternative energy crafts are nothing new. Back in the day (1902 in fact!), Mary Gordon was an electric-powered boat sporting stained glass windows, silk curtains and luxurious, velvet covered chairs.
So how far have we really come since then?
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.
The original Spiral Island was the talk of the world: a man-made floating island constructed from 250,000 plastic bottles that could drift and relocate as needed until it was destroyed by disaster. Now the new Spiral Island is slated to open to the public within the next few months in Laguna Makax near Isla Mujeres. The new island has drawn in donations, volunteers and visitors from all parts of the world and walks of life – people inspired by what may be one of the most impressive do-it-yourself projects of modern times.
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.
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.
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.
It is all too easy to get excited about the next big sustainable technology for saving energy or producing non-polluting power – and forget the flaws in many of these ideas. Some of the best projects show smart out-of-the-box thinking but lack feasibility or, in some cases, might do more harm than good. While these ideas may not work at least scientists, politicians and other innovators are beginning to explore alternatives.
When it comes to vehicles, green can mean many things. Many supposedly environmentally friendly vehicles also aren’t as green as people might assume at first glance. These three articles provide some facts, figures and humorous anecdotes about what it really means to go green.
