I know, and I largely agree with you, too. But you're comparing the National Forest land with an ideal that it never was in the first place.

The American West was first stolen from native americans, then gifted to the barons of railroads, mining, logging, and ranching, because they owned the government - Federal to a large degree but state to a huge degree. It was an incredible battle for Teddy Roosevelt to establish federal control of the lands and the US Forest Service at all, and would never happen again today, who would even dare try? The land was already being exploited and it took decades to reign it in even to the point where it is now. Setting aside all that land as wilderness was never in the cards. Look at the entrance signs - "Land of Many Uses." It is a compromise. Europe has nothing like it. Don't get me wrong, we should absolutely keep bitching about sweetheard deals and encroachment, but I also run trails in the national forest near my home every morning before breakfast, and I feel very lucky to do so.

The odds of them actually fining a reporter doing anything like reporting are nil. That is clearly not the intent of it, as it has an exception for reporting news. I guess the problem is writing the law in a way that disallows shooting commercials or movies, without creating some objectionable corner cases.

Unless there has actually been any issue with this, it's just another trumped up nonstory that will be inflated to cartoonish proportions in the comments to follow.

The AI itself seems alright, although Atari-era graphics and gameplay is extremely simplified compared the imagery and real-world dynamics that robotics struggles with routinely. So, for example, the AI doesn't seem necessarily very advanced compared to a self-driving car.

What I would like to know how to do is to get $500M for so little track record, intellectual property, or even publications. I don't get it.

Comment Re:Plain solar panels cost less (Score 1) 268

Wikipedia says: "Semiconductor properties allow solar cells to operate more efficiently in concentrated light, as long as the cell Junction temperature is kept cool by suitable heat sinks. Efficiency of multijunction photovoltaic cells developed in research is upward of 44% today, with the potential to approach 50% in the coming years.[4]"

So not 4x efficiency like I said, but still 2x.

Then if you can focus 20 times the light on it you're generating slightly less than 20X the power

No, actually more like 80X! Because it converts the light to electricity at 80% efficiency instead of 15%-20% for un-concentrated. This is due to the extremely steep temperature gradient between the super-heated front-face diode receiving the sunlight and the water-cooled electrode behind it. (I'm sure somebody else can explain the physics better).

The point being, say you have a rooftop in a city and want to make power - in that case, density matters.

And if this were stupid-expensive, it would be a research project and not a product.

No, I don't mean it in such a partisan way. For example, if one candidate in the democratic party primaries said, "let's let the science tell us what we need to do to prevent global warming, and then figure out what it will cost, and do it" - I predict they would lose the democratic primary race to another democrat who would take a more convenient "centrist" position (thus playing the role of Reagan). What I am saying is, the American public for the most part subscribes to the Bush 41 position - willing to look for ways to improve so long as it's painless, but not to interfere with our "way of life." (Carter was an anomaly, elected during a moment of national contrition - and that didn't last long!)
