Tl:dr The max theoretical efficiency for a silicon solar cell is estimated to be 29.4% with real world high end modules topping out at 26.8%

26% in a lab is not the same as 26% in the field after 5 years, but it is nonetheless a good result.

Solar scales out well, so low conversion effiency isn't really what determines whether an installation is feasible or not.

If you're evaluating cheap 20% efficient panels vs expensive 25% efficiency panels, you need only scale up the area of cheap panels by 25% to match output. Plus, panels that start at a lower efficiency experience less derating over time, so the difference in performance diminishes as an installation ages.

A conviction by the Senate is the only legal way to hold a rogue president accountable. The founding fathers foresaw the branches of government vying for more power, but they did not expect a congress to work with an executive against the interests of the people.

Minor notation quibble: I suspect you were thinking of the hecto prefix. Centimillionaire would imply a net worth of $10k which isn't going to get you the time of day from a republican.

I hope AMD and Intel will recognize the opportunity to maintain their cadence and earn some market share.

Since everything is projection; what's on his email servers?

The loss in trust may be permanent, but I think there is still a real desire to develop new good relations. If the US were to pass meaningful reforms and approach old allies on a more equal footing in real negotiation and not primarily the role as the big bad bully, I think a new framework of trust could be slowly built again.

Joining the ICC and not threatening invasion if they dare try to hold an American accountable would be a good start.

There have been a few of those, but it's always for DWI or similar when they aren't protected by their gaggle of goons.

I don't recall the media covering the fake electors of the Jan 6 coup hardly at all. The media loved to cover the big violent crowd becaus it was flashy. However, the fake elector scheme was the more significant crisis in my mind. That showed a planned and coordinated effort by people in power to subvert democracy.

Market cap and realized losses are completely different things. Reporting a change in market cap as a loss is misleading imo.

This dip might drive some volatility for a bit, but gold and silver are still at crazy high valuation. It isn't likely to affect you unless you've been speculatively buying precious metals and panic sold.

SpaceX was his one good company thanks to the work of people like Gwynne Shotwell. xAI must not have been getting enough investor interest and rather than admit it's a stinker, he's shackling spaceX with it.

If I were a spaceX investor, I would be absolutely pissed about this and talking to my attorneys.

We need to add digging/ tunneling to the grid.

It's a double entendre because firstly this is absurd, and also a vague reference to how when Trumps insurrectionists show up with guns they just get pardoned instead of executed.

I'll admit it's a bit of a stretch as far as jokes go.
