Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

How close are we to a solar powered car?

How close are we to a solar powered car? I mean a car that can depend on just solar power. Of course I don't believe we could ever create a car running on just solar power. I believe that a good car would be would be dual-receiving energy. One receiving electricity from solar and the other from it's own battery.
But really? How close are we to create a car that if was going to the Sahara could run more then 100mph, and just go on for hours as long as it received it's power from the sun? I know that we have created transparent solar panels which are terribly inefficient at about 1%,yet would provide more solar coverage of the car, but if it could reach efficiency at around 20% and a regular solar panel on the top of the car could receieve around 100%, would this be enough to power the car?
Also just to be more specific, the car would be a Tesla Model S with four people inside. Could it be done?

Even if solar panels were 100% efficient,you wouldnt come close to 100mph.
The average energy from the sun per square meter on a hot clear day that hits the earths surface is around the equivalent to 1300 watts. Your average 1 ton car would have a usable surface area of about 8 to 9 square meters(boot,roof,bonnet) to fix your solar panels to. So this would give you a total of around 11700 watts-or 11.7kilowatts,or 15.7 HP equivalent.
Now, im yet to see a 1 ton car with 4 people in it being propelled at 100mph by a 15.7hp engine.

Maybe !!maybe!! it could be done on rail's,where the friction is very low,and the body shape is very aerodynamic-but that is a big !maybe!

Not commercial and not ready for daily use..


But there is some real research and progress..
Topspeed over 150 kmh possible.


The Dutch Solar team has won a few challenges in a row with their purely solar powered car.

   For a bit of fun we're having a go with a Tesla car and a good few panels on
the roof (the workshop roof rather than the car's roof).
I don't think it's particularly economically viable, but it's a start.
