What about fusion energy? I just watched this video on LockheedMartin’s channel.
As many people said before, the main problem with electric cars is that they still need to generate the electricity in some way. Electricity is not a power source like fuel. It is a power conductor, you need to produce electricity (that is the main difference with fuel)
So an electric car is as eco friendly as the energy production which fuels it.
But here we have a problem. Windmills are the most eco friendly energy available, because is the less pollutant, mostly because you need less energy per KW when making the generator + wind mill.
On the other hand, the good old photovoltaic energy is no as much eco friendly as they said, since the silicate panel manufacturing process spends a LOT of energy, and this energy comes from fossil fuels.
As many, many people have said, the future is fusion energy. Clean and with a lot of fuel available (well, not straight fuel, but it is easy to acquire)
But forget about having a fusion generator at home. Not only it is dangerous (If your neighbour cannot maintain its own house, he won’t maintain the generator!) but it is useless. What we will have is the same as we have now, big powerplants, which will feed the electrical power lines as we do now.
And with that electricity we can charge our electric cars, or produce hydrogen for hydrogen cells. Most people will have electric urban cars, but for long range transport + highway cars, the hydrogen cells are better, just because you can fill your car in 5 minutes like you can do with petrol.
Also, the electric drive train is very, very simple. Much simpler than the mechanics of a ICE, which will allow new car configurations, like one tested by Honda, with all the drive train + cells/batteries in the ground of the car, and an interchangeable chassis, where you can change from a coupe, to a van, to a hatchback, with the same drive train and a fast visit to the car dealer.
Unfortunately, oil is still plenty enough and cheap enough, and will be for the next 100 years, so I don’t think we will see that. they are just investing now to have something available when the next oil crisis (the big one) starts. The states are keeping their strategic reserves to allow a smooth change between technologies, which can take at least 20 years.
