A former Formula 1 engineer, Guy Négre, has signed a deal with an Indian company (Tatra Motors) to produce an air-driven vehicle.
This car works on compressed air, thus having zero emissions.
A completely non-pollutant vehicle.
Or is it? Its air tank must be filled with an air compressor, either the in-built electric compressor or an industrial compressor.
So although the car by itself is environmentally friendly, charging it means you'll have to use electricity.
Now, you can have a windmill generating the electricity, or a solar panel, that way you won't be using fossil fuels to generate the electricity for the compressor, but then you'll have to spend energy to build the windmill or the photovoltaic cells...
Don't get me wrong, I DO think this car is great and I do think we must try and find environmentally friendly solutions. But the main issue remains in electricity. Most of the processes in our so called civilized world require energy, at some point or another. Nuclear power is dangerous and generates pollution. Fossil fuels aren't going to last forever and you all heard about the problems associated with them.
As for all the other sources of energy... they are not efficient enough to satisfy our needs for energy.
Without wanting to seem pessimistic, but assuming it will take a long time to solve our energy problems, maybe we all should really focus on the other side of the equation and instead try to reduce our need for energy. Walk instead of driving, use public transportation, turn off the lights when you don't need them, unplug all the useless electrical gizmos around the house. Electrical can opener? What for?
Off course this idea can also mean don't spend so much time on the internet, turn off the computer...
In the meanwhile, a big HURRAY!!! for Guy Négre for is contribution!
