Solar is a lot cheaper than nuclear though: Everyday the production of solar electricity has to be curtailed when the amount of kWh produced exceeds the demand. Those kWh in excess, by definition cannot be sold and are hence free (as in fre

They are not here to mitigate global warming. They plan to make big money. There is a market for natural gas, they have a precise estimate of costs (including carbon capture) and their costs are lower than fracking. No new tech. No big upfr

Solar is a lot cheaper though. Curtailment is the key word. The production of solar electricity has to be curtailed everyday when the amount of kWh produced exceeds the demand and cannot be stored. Those kWh are free.

Yes, they put a cost on everything. The solar panels, the capture, water electrolysis, Sabatier reaction, etc... All very predictable. And how much they'll be making per year selling their gas at market prices. And they already signed

I'm not aware of He3 easily becoming T. I know T spontaneously becomes He3 (emitting a positron and a neutrino) with some probability, a very low one, not relevant at the scale of a pulse

You are right, it's a pulsed system. The operation goes like this: 1. Fill the chamber with D and He3 2. Ionize the fuel and compress the plasma 3. The fusion starts and pushes back the magnetic field producing electricity 4. Stop ever

I thought Trenta was already recapturing electricity and feeding it back to the capacitor banks. This not clear from this video but it was a previous claim. Otherwise I don't think they would have said "feeding electricity to the

Exactly, but the fuel cycle is actually more subtle than that: When compressing the D+He3 plasma, inevitabily some D will also fuse together. And since one in two D+D reaction yields He3+n, if you fine tune the proportion D/He3, the D+

The learning cycle is too long. It takes ~10 years to build a reactor, so if you spot a way to improve on costs or safety it will take another 10 years for the innovation to see the light. At the contrary in renewables the learning cycle is

Flying less or more generally consuming less is not going to solve the climate crisis. We need to go to net zero emissions and then to net negative emission, we need to capture the excess of GHGs to go back to a level where warming stops. I

There is this misconception that fusion is far in the future. But these startups are aiming at commercial fusion before 2030. For instance, Helion plans for net electricity by 2024, in two years. Maybe the employees and the investors of the
