Arg! Running out of time again. A principle to remember before I forget

Have to make this fast because the thought just came in.  The intermittent nature of wind and solar make are poor solutions for the grid because the grid require continuous power.  Therein lies a principle, if you can extract it.

The principle  ( this is temporary as I don't have time to evaluate it ) is that for purposes of generating power, if you need a continuous supply, the solution must also be continuous.  If you want to use intermittent supplies, you must convert it to continuous, or it doesn't solve the problem that you claim that you want to solve.  Hence, for the grid, the use of solar and wind will require that you use fossil fuels as a backup.  This isn't solving the problem of emissions because the fossil fuels are still being used.

How do you make this work in the context of automotive solutions?  Elon Musk's Tesla battery electric car purportedly solves the emission problem, but it doesn't really do that.  That's true even if you use his other company, Solar City, in order to supply electricity for your Tesla.  However, Solar City puts the electricity on the grid, and the supply is intermittent in nature.  This means that Tesla is not really a solution to the emissions problem.

To solve that, you need to store the electricity on site and then use that electricity to recharge the batteries at night.  That's because at night, while you are sleeping, the intermittency problem doesn't exist.  As long as the car isn't moving, it can be supplied by an intermittent source, like store solar power in a capacitor or battery.

This requires more equipment though, and therefore may not be economical.  That's a topic for another discussion.

By the way, glad to see that Market.org does support LFTR technology.
