You're correct, that was sloppy wording on my part.

The idea is to direct all of the nanotube-emitted light onto the PV cells, so hopefully you won't see anything. Citing the Rice article: > Because electrons in nanotubes can only travel in one direction, the aligned films are metall

The article doesn't provide very much detail, but it's absolutely possible to absorb multiple low-energy photons and emit fewer higher-energy ones, see e.g. https://en.wikipedia.org/wiki/Second-harmonic_genera

Hot things glow. Medium hot things (like you) emit lots of infrared light. Really hot things (like lightbulbs) emit infrared and visible light. Ridiculously hot things (like the sun) emit infrared, visible light, and higher-energy radiati

You're confused – heat isn't being converted into anything. The article conflates the words "heat" and "infrared radiation", which are not at all the same thing. As a rule, everything around you glows – in othe

Huh? The Wikipedia article you linked puts the moon into > Unrestricted Category V: “Earth-return missions from bodies deemed by scientific opinion to have no indigenous life forms.”

You need to look beyond just US corn. Crop yields need to continue increasing globally just to keep up with population growth, which going to be a significant challenge. At the same time, farmland is being lost to urbanization and desertifi

Well of course – almost nobody is really campaigning for independence. HK is very much dependent on the mainland, and that's understood. The demands are much more narrow: for the extradition bill to be scrapped, for Carrie Lam to step

Yeah, this absolutely crucial piece of information is missing from most articles like this one, a journalistic failure I find incomprehensible. Anyways, the Woods Hole Research center claims that boreal forest fires are not included in cu

Consider using a cookie for that purpose. I was looking for the calculator everywhere until I realized I had to enter my email first. That's a pretty big trust hurdle – no thanks. I suggest you let people use the calculator freely, and

Correct – more effective terms are climate crisis, climate chaos, climate emergency.

They aren't typically found in nature in the form in which we consume them. They require human processing (even if it's much less processing than what goes into making a frozen pizza).

Wild speculation: I wonder whether loudness is actually a design goal, to make the dryer appear more powerful. A sizable number of people are skeptical of electric vehicles, because they perceive an earth-shaking vroooom to be an essentia

You can look at the issue however you want, but at the end of the day somebody is going to have to pay for the renewable energy and carbon sequestration tech. We can fund them with taxpayer money, which means the average Joe pays, and pol

I don't know about France, but this model is now reality in (at least part of) Canada, and the US has a bill before the House [0]. It's the only politically viable way of implementing carbon pricing. [0] https://energyi

> "Paying for the damage" is this some kind of joke? What about all the other polluters? Shipping? Coal plants? Right – tax them too, and distribute the revenue back to households. That way it's not a regressive tax, but a

All of this has been studied and modeled extensively. It's called elasticity of demand. The fact that professional trading firms are selling airline stock, pushing the price down, shows you that yes, this will indeed have an effect.

Carbon taxes are the most efficient way to let the market work out technical solutions to the climate crisis. Period. If you're worried about regressive taxation, check out the fee-and-dividend model, where all revenue is returned to h

Carbon pricing, carbon pricing, carbon pricing. No other approach will allow technical solutions to emerge faster. If you want to do something about climate change, talk to your politicians about carbon pricing. In the US there is finally a

Good question. The answer lies in multilateral agreements (Paris etc.) and in so-called Border Carbon Adjustments. The latter have to be implemented carefully so as not to violate any WTO rules [0], but it's possible. [0] https:/

> Trees readily plant themselves in areas they are well adapted to. I am very skeptical if that's true – see formerly forested areas like Iceland, Brazil, etc. It's not easy for a single sapling to grow into a tree, even if the

Absolutely true. And tree planting appears (to me) to be an underappreciated philanthropic cause area. This study could help change that.

Interesting – we need more of such studies. Check out Drawdown [0] for other interventions with quantified costs/benefits. Economists widely agree that carbon pricing is the most effective way to fix climate change [1], and fee-and-div

The range matters – had they found 10 serial numbers between 100000 and 101000, would the mean still be a meaningful estimate of the production rate? In this case, the author just tacitly assumes the minimum to be zero.

Another favourite of mine is mpsyt – a terminal interface for youtube-dl. I stream music for hours without ever getting ads or even having to have Youtube open in the browser.

I'm curious why they use capsules of fine powder, instead of glued/sintered pellets. Perhaps you can provide some insight?

"Learning" here means averaging over many rollouts (i.e. simulation runs) of a policy. Naturally, time only increases in those runs, as you require.

I had no idea what this did until I watched the video. Suggestion: let people play with the map customization tool directly on the landing page, then charge them for changing the date/location and for hi-res exports.

I agree with the sentiment, if not with the needlessly aggressive wording. Also, the spelling you're looking for is hordes, not hoards.
