Comment Re:Heat (Score 1) 182

I would be more interested in this if it worked the other way, warming my house.

There are lots of designs for doing that. Look at any renewable energy bulletin board (such as fieldlines.com).

Common thread is:
  - Black (or otherwise visible light absorbing) target.
  - In an insulated box.
  - With a glass window (that does NOT have an infrared reflective coating)
  - And some way of transferring the heat from the black target to the house air.

Glass is opaque to infrared and passes visible light. Sunlight goes through, is absorbed by the black material, and heats it (to the tune of about a kilowatt per square meter at noon). The material re-radiates, but it is far too cool to re-radiate in the visible spectrum. So it re-radiates in the infrared, which doesn't escape through the glass and is thus re-absorbed.

It's called "The Greenhouse Effect". B-)

In one of my favorite designs the black target is a series of tubes consisting of used aluminum drink cans with the tops and bottoms removed, painted black. They're very good at absorbing light, because it takes multiple bounces down the valley between the tubes, giving the paint many chances to absorb it. A 4" computer fan pumps air through the box to extract the heat.

But there are LOTS of other designs. Including houses with large south or south-east facing windows and overhanging roofs that shade them in the summer but not in the winter (to rough-tune the absorption). The floor, walls, furniture, etc. serve as the visible light absorber.

My ranch house works like that - a little too well. In the afternoon it will git to 90+ degrees when it's single-digit temperatures outside.

Comment Re:Too good to be true. (Score 1) 182

It's a neat idea, but what happens in the winter?

Put a cover over it.

Glass is good. It is pretty much opaque to far infrared. Instead of seeing the cosmic background temperature of a few degrees kelvin, it will see the temperature of the glass - which is about the same as its own temperature. So the radiative heat flow will be just about zero.

But ANYTHING opaque to infrared will do the same.

Another approach: Instead of coating the house, coat a radiative cooler to make chill water, and pump that through a heat exchanger in your forced air heating/air conditioning system. Don't want cooling? Don't pump the water. (Adjust how much you pump it to regulate your temperature.)

That's not "no power", but pumping chill water is very little power, and you need to circulate the air anyhow. Most of the energy cost of air conditioning is refrigeration, and you still get that for free.

Comment RTFA. They DID try it on people. (Score 1) 153

RTFA. Then follow the link to the paper. They DID try it on humans. Worked reasonably well (though the sample was small so it was more "does this maybe work on people, too? Is it worth a big study to check?" rather than "do all the results reproduce in people just like mice or are they quantitatively different in THIS way?").

Interestingly, they used a proprietary commercial boxed Fasting Mimicing Diet - L-Nutra's ProLon (Developed by a team including a USC Davis professor specializing in gerontology and life-extension) - on the human experimental subjects.

Comment Re:I blame Trump. (Score 5, Insightful) 991

Well, that's one way of looking at it. Another way is that black people do a lot more murder on a per capita basis. As it turns out, the chances of getting killed by a white guy are less for a black person than the reverse. Which is indicative of the overall murder rate in the black community being several times (something like 5+ times) what it is amongst whites.

Some source data

Anyway paying undue attention to a single person amongst the 6k or so that are going to die this year is politically motivated, as usual.

I agree with you. People say a lot of stupid things when they are drunk. But let's not let any opportunity to blame Trump go to waste, right?

And Leftists wonder why they are getting tuned out.

500 white people are killed by blacks every year and 200 blacks are killed by whites every year. One group is 70% of the country, the other is 13% of the country. I notice the same people whining about this event aren't paying attention to those statistics. A couple people assuredly died in interracial murders since that story broke.

But this one drunken fight in Kansas - we have no idea what was actually said and what provoked this - is somehow more significant.

USPS DID loose the package!

They they also lose your elementary school text books in transit right at that critical moment when your teacher was trying to get you to understand the difference between "loose" and "lose?"

the box was sitting in a Atlanta for over a month

Which was probably the same week when you'd have been learning about using "an" in front of words that start with vowels, though that still doesn't help that sentence make any more sense. An Atlanta what?

the recipient who's address is on the box

The recipient who is address on the box? Or did you mean "whose?"

It's getting pretty bad out there. It's a good thing people are spending thousands of dollars and hours reviving old 8-bit video games! Whew!

Yeah, he'll never get around, for example, to orders reducing regulatory burdens. Oh, right! Already done. Or any movement at all to start to undo the financial stranglehold that Obamacare has put onto people forced to fear IRS enforcement if they don't go broke buying insurance they can't use ... oh, right! Already done, with more under way. I guess we could run down the long list, but you already know it and you're pretending you don't so you can engage in more lefty denialism. Carry on! It obviously is your coping mechanism.

Comment Re:It's the suburbs... (Score 1) 107

The suburbs I grew up in didn't have Netflix...but then I grew up before the internet. Our nearest fast food place was a couple miles away, and we had a baseball field at the end of our street where my friends and I used to play ball. We spent more of our waking hours outside than in. I'd typically put 1000 miles on my bicycle during the summer.

So, while you may blame the 'burbs, I'd argue that it's a generational issue.

Comment Re:It is a dog's life. (Score 2) 107

While dog (Kaygogi) is eaten, it's rather uncommon. I lived there for six years, and only came across it once when my landlord invited me to their elderly grandmother's birthday.

I haven't read the article, but my knee-jerk reaction to the headline is disbelief. Korea is highly polluted, with a very large smoking population, and tuberculosis was much more common there than in the US. Many homes are heated using "Ondal", a form of charcoal, smoking out into the open air. Of the roughly 50 countries I've been to, Korea had the worst drivers...Wikipedia shows 18.2 fatalities/billion km...the U.S. has 7.3 in comparison. The country also has a habit of hiding issues...they refused to admit there were any cases of AIDS for quite a while.
