Most of us still use today the traditional incandescent light bulbs to light our homes. But as the traditional light bulbs have a high energy consumption, most turn nowadays to compact fluorescent light bulbs(CFLs).
Geothermal energy is considered to be the ultimate energy source in terms of reliability. Since it doesn't depend on day or night, or other external factor, it is practically undisturbable and has a huge potential.
What can you do with a steam powered engine, a LEGO toy kit, some wood sticks and a USB cable?
There have already been successful experiments involving solar powered boats, and there have already been people sailing them in the last ten years. Still, all of them have something in common: they use photovoltaic cells as an intermediate between the sunlight the mechanical work.
Jon Boehmer, a Norwegian based in Kenya, developed a solar powered cooker that can reduce greenhouse gases at a large scale. The cardbox named the "Kyoto Box", costs 5 Euro($ 6,60) to make, and is designed for the usage of 3 billion people that use firewood as a heating source for cooking.
It seems natural that military applications take over the new technology. It seems natural that people use their best to defeat others, instead of helping their civilians.
After so much seriousness, let's try and take a look at something else, a new invention that will surely change the way we live, think, and act during our irresponsible ride to the grocery store.
Using microscopic creatures as our friends is not a new idea, not it has been used recently. Nowadays, pushed by our green energy needs, we have to find solutions by using and probably killing some of our little friends to make us energy. This phrase sounded like the madhouse, now let's get to the real subject.
Prof. David Milstein, and his colleagues from the Weizmann Institute, the Organic Chemistry Department, demonstrated a new way of generating hydrogen and oxygen, through a series of steps that involve applying heat, light, and a special catalyst.
As many producers announce their hybrid or electric cars, it's a more obvious sign that the future is for electric cars.
There is a competition to be the first one to produce electric cars and have them on the road.
China is trying to get on the track for this and they will try to produce 500 000 electric cars in the next two years. It might not sound much, but compared to the 2100 produced last year, it's a great evolution.
