Entergy Louisiana CEO lets it slip on Meta's electricity demands. 4,500 MW is about four times the peak electricity demand of the entire city of New Orleans. May realized immediately what he had done. “I won’t make you say it again,” an attorney for the Union of Concerned Scientists responded.

Valar’s Project Beehive: 456 reactors × 25 MW = 11.4 GW, but the stated total is 9.6 GW. What explains the gap?

Valar Atomics (Ward 250 went critical in Utah in June under DOE’s Reactor Pilot Program) has proposed Project Beehive: 456 reactors on about 9,000 acres of BLM land near Price, Utah, for a stated 9.6 GW supplying data centers.

A few numbers I couldn’t reconcile:

  • Capacity: 456 × 25 MW per unit is 11.4 GW, not 9.6. Is that derating, spares or phasing? I haven’t found an explanation from the company.
  • Heat: at roughly 40% thermal-to-electric conversion, 9.6 GW of electricity means about 24 GW of reactor heat, so around 14 GW has to be rejected, in a dry part of Utah. For comparison, the whole state’s average electricity demand in 2024 was about 4 GW.
  • Fuel: a generic high-temperature gas reactor benchmark puts a fleet this size at tens of tonnes of HALEU a year. That’s my rough estimate on a generic design, since Valar’s isn’t public, but US HALEU deliveries so far are in the hundreds of kilograms.

Has anyone seen a filing or application that addresses any of these?

How do renewable natural gas projects, especially in urban areas, pencil out?

I find the large wastewater treatment plant, landfill gas, and municipal anaerobic digesters for organic waste as an alternative / supplement to composting all very interesting and was wondering how these pencil out in terms of emissions and cost-effectiveness.

Is the value of the natural gas attained for local use usually not equal to cost of implementing and maintaining these versus just dumping and buying natural gas from other sources?

My impression is that these are not the usual way that wastewater or organic waste are dealt with in urban areas, less sure about landfill gas, but I'm also not sure about that.

Updates for Getting Payment on the Rivian $250 million Settlement

Hey guys, if you missed it, Rivian settled $250 million with investors over claims that it failed to disclose the true cost of producing its vehicles. And, I just found out that they’re accepting claims even though the deadline has passed.

Quick recap: In 2022, Rivian was accused of misleading investors about its vehicle pricing and production costs. In short, the company promoted its R1T pickup and R1S SUV as competitively priced electric vehicles, but investors later alleged that Rivian was losing substantial amounts of money on each vehicle sold and failed to clearly disclose how severe the cost gap was. As supply-chain issues and material costs increased, Rivian announced major price hikes that sparked customer backlash and raised concerns about the company’s financial outlook.

Now, the good news is that the company agreed to settle $250 million with them, and even though the deadline has passed recently, they’re accepting late claims.

So, if you invested in $RIVN when all of this happened, you can still check the details and file your claim here.

Anyway, has anyone here invested in $RIVN at that time? How much were your losses, if so?
