It needs to produce about 100X more energy if it wants to produce grid power. It didn't achieve net break even compared to the amount of energy that went into the NIF equipment to produce the shot. Not even close.

His mom literally runs a major fundraising arm of the DNC.

We're talking about a major political donor who just defrauded people for billions of dollars, whose parents are extremely well connected to the DNC and have actually written a substantial amount of legislation put forward by Democratic lawmakers, and who was sleeping with the niece of the current head of the SEC who was appointed by Biden. He has every single motivation to lie about this.

>I don't know if that's true, but it's possible.

Sounds an awful lot like a conspiracy theory, my dude.

So 0.6% of his overall contributions? Not even a full percent?

> despite having donated to both parties extensively

> both

He was the second biggest donor to the DNC after George Soros. I'm not aware of any RNC contributions.

Truly incredible that such a small group of people could be so well represented in academia and media. My hat goes off to them!

I don't think that's correct. It appears that this was designed using topology optimization.

Again, as with the sibling comment, I would like to see empirical data on the cost viability of existing solar and wind installations. Most of the links posted so far seem to present projections about the future, which seems to imply that wind and solar tend to be higher cost today.

I am not asking for forecasts of what could theoretically happen in the future: I want to see an analysis of existing installations.

The PDF you linked does not contain empirical data on existing solar and wind installations. It's an investment pitch.

> A clean power grid means cheaper power.

That's a pretty wild assertion, given current events. Care to back it up with some evidence from a neutral source?

I am still struggling to understand how migrating to a censorship-resistant platform will mitigate concerns about a lack of strict content moderation at twitter.

Would the article have been published if the author found evidence to the contrary?

Same, just signed up for a paid account today. Looks like the full $8 blue checkmark experience hasn't been released yet though.

Having implemented them myself on an ad hoc basis in pytorch, I don't see how they're much different than training a deep learning model.

What about interior point methods?

There are a lot of large-scale optimization problems in industry that are still compute bound. Currently available solvers are either single threaded on the CPU, or offer "parallelism" by running copies of the same problem on multiple threads, but with different initial conditions in hopes that one happens to converge faster.
