Solar & Batteries Will power the future..

[Uncle Gizmo]

I've been following James for over a year now. He is usually a guest on other people's youtube channels where he talks a lot of sense.

Here he predicts the advent of solar and batteries.

The computers needed to run AI will use a lot of power! The solution, build the data centres where their is ample free energy, use that and then link the data centres back to humanity with the starlink system.

This is how James explains it:-

Starlink now has around 1.7 million customers in 70 odd countries around the world and is predicted to make six billion this year!

If anyone tells you that electric cars pollute more than internal combustion engine cars then show them this video!

I've said it elsewhere in the forums and I'll say it here. The problem is enthalpy, a measure of energy in a given chemical system. It applies to any battery based on a chemical reaction. The energy available through chemical reactions depends on the speed of the reaction. Due to enthalpy formulas, that energy availability is strongly dependent on temperature.

The specific thermal coefficients vary from battery to battery, but in general, for every 10 degrees C that you drop, you lose 50% of your power. It's a compound interest problem, so the next 10 degrees is 25% more loss., then 12.5%, etc. When the temperature shifts from 35 degr. C to 5 degr. C, you have lost 87.5 % of your power. Then go to -5 degr. C and lose ANOTHER 6.125% - or a total of 93.7%. EVs just DO NOT LIKE cold weather.

With an internal combustion engine (ICE), the problem is a little different. Batteries depend on reduction/oxidation (redox) reactions, and technically so do combustion reactions. But the inefficiencies of the ICE means that the engine will warm up quickly whereas the EV has a lot less waste heat.
