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.

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.

Clearly we can’t very well tear down all of the world’s old skyscrapers for not being environmentally friendly - that kind of approach would itself be (ironic and) wasteful. At the same time, many of these buildings are projected to last for decades (or centuries) more. So what is the solution for making them green now? One rather clever proposal involves adding an auxiliary environmental layer to the existing structures that could house gardening and natural wind power production spaces.

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.

Except perhaps in the bathroom, do you really need any kind of paper? These days it seems like paper is just an intermediate step or default conclusion - a copy that will eventually be scanned in or a digitally written paper printed out at the end. Still, is paperless the solution to environmental problems or simply wasteful in another way?

Some families are choosing to go entirely paperless though this choice isn’t necessarily a complete fix for the environment: paperless lists, games, educational tools and other devices still require energy to run. Also, with the virtually unlimited supply of information online and in digital form many people don’t think twice about printing out a copy for temporary use and then discarding it.

Also, while paper use is decreasing in many developed countries there are many places in the world where paper use is still on the rise, such as China and South America. Hopefully as paperless approaches become more the norm at work and at home energy efficiency can be increased and the world will begin to adjust to the new technologies without needing to print out unnecessary hard copies.
