Everyone seems concerned with the economy nowadays. Indeed it appears there is some crisis going on. So few people buy cars now that major car manufacturers are on the verge of bankruptcy. Now, how come people are not buying cars?
One reason is the bad economy. Yet there is another aspect, namely the global warming. People are wary of putting their hard-earned cash into a gas-powered vehicle.
I am sure we will soon see a breakthrough for electric cars. 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 contributing factor is that an electric engine doesn't work when it doesn't have to. Such an engine doesn't need an "idle", for example.
Imagine that most cars are now running on electricity instead of gasoline. Well, this will of course lead to a greater demand for electric energy. And I guess none of us wants to get a higher utility bill? My answer to that: get off the grid, get freedom with solar power! Solar panels for homes are the best thing since sliced bread. Photovoltaic panels can be set up on the roof of your house.
And then your house and your vehicle are both solar-powered. There is no pollution and once the system is set up, the rest is a free ride.
You may think that this will be something very expensive to install. OK, this used to be true but times are changing. Intense r&d is cutting the cost of producing solar cells. Everyone knows that there is a huge demand for cheap solar power products. Therefore several companies are working hard to make them.
One company, Nanosolar, has found a way to make solar panels in an assembly line process. You can compare the process to how you print 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!
