There is a real concern about us running out of oil or at least it becoming such a scarce resource that the price of petrol for cars becomes too much for most people to afford. There is the development of electric cars and as we get better at converting clean energy (wind, solar, tidal) into electricity then I think the electric car will become the vehicle of choice for the future.
Fossil fuels running out are a big worry that is why I’m working on solar energy and hydrogen fuel generation. There are at the moment two main oppositions
Electric cars (like the G-Wiz or the Tesla Roadster) these use batteries that are recharged from your home or a recharging station.
Hydrogen Fuel cell cars (like the Honda Clarity) this uses Hydrogen gas and reacts it with the Oxygen in the air to generate electricity and water.
I guess humans are pretty resourceful so we’ll have an alternative when if we run out of oil! If I could tell you what it was then I’d be very rich because everyone is looking for it. At the moment, the best guess is probably hydrogen fuel cells. These are clean and only water comes out of the exhaust pipe. The downside is that it takes a lot of energy to make them.
The message I suppose is that we need to save oil and not use it all!
