Make A Wind Turbine

Everyone seems concerned with the economy nowadays. It seems there is a crisis going on. Car makers such as General Motors are going bankrupt because of the slow market. Now, how come people are not buying cars?

Naturally, part of the reason is the current recession. But there is another thing: the global warming. Many folks hesitate to throw their money on buying a gasoline-powered vehicle.

Soon, there will be a shift toward electric cars, this seems certain. There is really only one weakness with electric cars: batteries haven’t been powerful enough. But better batteries are being developed. As soon as these are manufactured in full scale, the old gas-powered vehicle becomes obsolete.

Electric cars are actually much more efficient than traditional vehicles. One of the reasons for this is that an electric engine works only when it really needs to. There is no “idle” on such an engine.

Suppose you  replace most current cars with electric ones. Well, this will of course lead to a greater demand for electric energy. And of course nobody likes to pay more for their utilities? OK, to that I say: claim your freedom from the grid with your own solar power! Solar panels for homes are the best thing since sliced bread. You can install your own photovoltaic panels on your very own rooftop.

And then you can get electricity for your house and your car, straight from the sun. The system does not cause any pollution, plus it is free once set up.

You may think that this will be something very expensive to install. Well, that used to be the case but not anymore. The cost of making solar cells is going down rapidly. Everyone knows that there is a huge demand for cheap solar power products. Which causes a bunch of manufacturing companies to put great efforts into making them.

One company, Nanosolar, has found a way to make solar panels in an assembly line process. The process is a bit like printing newspapers. A semiconducting material which looks like paint is sprayed on to a metal foil. The process is fast once everything is put together.

Just think of the enormous surface area of all rooftops – what a tremendous potential there!
