I know my opinion doesn't matter to those who matter, but it rather matters to me and probably to you, my reader. Since I saw what electricity could mean to the car industry and how it can revolutionize the way and what cars consume energy, I totally changed my mind about biofuels and other burnable liquids or solids. They are here, are working, but not for long - at least I hope so.
I guess I don't have to emphasize the importance of batteries in an electric car economy of the future. I also don't have to tell anyone that many manufacturers pursue making ultracapacitors for their ability to quickly charge, discharge, and store a huge amount of energy - the perfect combination for an on-the-fly highway recharging.
We are used to throwing our garbage in the bin, dispose it, and then forget it (and pay the monthly garbage collecting tax). What we often hear is that piles of garbage have saturated square kilometers in big cities, and that by making us comfortable, the garbage company (and, indirectly, us) pollutes the soil and the environment on a very large scale.
Even though plastic solar cells are cheaper to produce and they have some advantages like lightweight and flexibility , they still miss one important thing: the efficiency. Researchers are optimist that in the years to come, the polymer solar cells will be able to compete from the efficiency point of view with the silicon solar cells as well taking into account the fact that plastic solar cell have improved their efficiency each year.
The world's most expensive and exotic experiment was thought to be CERN. Few people know that the EU, US, China, and Japan have invested billions of dollars to construct the International Thermonuclear Experimental Reactor (ITER) that would use nuclear fusion instead of fission, like all nuclear power plants do today.
Although it has many opponents even among green technology sustainers, the good-old battery still evolves to help us have those all-electric vehicles beneath us, and make us drive cleaner and faster than ever.
Silicon photovoltaic cells are preferred in today's market conditions and technological implementations because they are cheap, silicon is abundant and the ongoing research has made them more and more efficient. Still, manufacturing the PV cells is very energy consuming, and they are very fragile and prone to breaking in the most mildly hostile situations (hailstorms).
Until now, in order to make more powerful wind turbines, you had to make longer blades, so they could capture more incoming air and transform it into mechanical work. Leviathan Energy, led by dr. Daniel Farb, has refreshed this approach towards increased efficiency not by increasing the blades, but by making the wind hit them differently.
Who said that the nuclear age is over is not quite right. Nuclear weapons exist all over the world since WW2, and they are being stored in all kinds of places, including submarines. These nuclear supplies could give us extra energy at a price similar to oil, if not better.
The waterproof solar cell phone will be sold starting with June by Japan's No.2 wireless provider, KDDI Corp. The gadget had been developed by Sharp Corp and promises carbon dioxide reduction by 80% charging from sunlight.
