We are reminded daily of the dwindling natural resources the human race uses to power all sorts of things, and we moan like stink about the cost of fuel. However, it may surprise you to know there are many scientists who are doing their best to get countries across the Globe to change their attitudes towards energy sources such as gas and electricity.
For instance, the US is currently the world leader in geothermal energy, which is a source of renewable energy that comes from the heat the earth generates. This heat is processed so it can produce electricity. Other renewable energy sources have been around for many years. We all know what a wind farm looks like, and I doubt anyone would question what a solar panel is.
These are all welcome technologies but what about transport companies? They still rely heavily on fuel sources such as diesel and petrol so they can get around. Sure, the vehicle industry has, and still is, trying to become greener and we have seen adverts for electric vehicles or vehicles that run on old cooking oil, and we’ve even had a little taster in terms of solar powered vehicles.
So there is a lot going on behind the scenes. The latest snippet of information I came across was courtesy of Sky News. They reported that scientists are looking into using the air we breathe as a renewable energy source. Sounds too good to be true doesn’t it? I’m no expert, but as far as I understand air will turn to liquid when it’s cooled to very low temperatures. When it’s heated back up it turns into gas. This gas is robust enough to drive an electric turbine or even power a car.
Welcome news indeed my friends, but I think it will be a long time before we’re all filling our vehicles with air!
