They mean that there are other much larger sites like Facebook which does take payments which has literally, literally, 1 million times the number of cases of those illegal types of things getting reported on their site.
One of the things that happens when consumers have options they didn't before is previously invisible preferences become expressible. What if the bulk of consumers never cared much about albums as coherent pieces of art? What if they only did so financially because it was the only way to get the separable pieces they did care about?
The advent of fast food has not exterminated fine dining. What's changed is that consumers have more choices. This did not signal the death of fine dining.
Yes I had some 555’s for almost 18 years of DAILY use and abuse and the band up top eventually broke. I could replace it if parts weren’t more than a new pair.
Half a century ago some companies actually planned for things like that - a small nuclear reactor that you would bury under your house and it would provide you with power for decades. It went the same way the nuclear car did - the concept would work but it's just too dangerous without constant supervision.
I had never heard of that, but the idea of it makes me think of all my neighbors growing up in the 90s who were spending tens of thousands of dollars cleaning up contamination from leaking underground heating oil tanks. It was a major issue for people buying and selling older houses...sellers hiding knowledge of leaking tanks, surprise discoveries etc. In the worst cases the soil decontamination could cost over $100k. I can only imagine what fun these end-of-life home nuclear reactors would be causing 50 years later!
I visited a home once that was built in the mid 20th century on the assumption that electricity would become too cheap to meter. The original heating system was described to me as just a bunch of resistive elements strung in the attic. I think the house actually got an award similar to LEED (or maybe it was LEED?) at its construction.
My parent's late 70s house has something like this. There are heating elements sandwiched between two layers of drywall in the ceiling. It actually works really well, because it heats objects rather than the air--sort of like the sun on a cool, cloudless day--but electricity is like 4x the cost of natural gas so it never gets used. Also, the attic has insufficient insulation, so half the heat would go the wrong way.
Oh yeah my (boarding) high school had a dorm built in the “electricity will soon be too cheap to meter” era and had heating elements set into the concrete floors. It housed like 50 students and used more electricity than all of the other buildings on the 500 student campus combined. The warm floors were very nice though!
Fair enough. Still, it's one thing to be specced for 24kW peak load (the breaker) and quite another to require 20kW continuous (two 10kW nuclear power plants). I still think 20kW is an awfully huge amount of power - the average US house only uses about 1 kilowatt when you smooth it out.
Same as in a car or any air conditioner. You pump a hot fluid to/from radiators. Look at the iss. See the big black structures always held perpendicular to the solar panels. Those are the radiators.
You build your walls out of Peltier elements. On one side of capsule, hot side will be in, cold side out, the other side of the capsule, the reverse. And then you use the generated power to drive a laser to shoot the energy right back into the sun.
The relationship between soot aerosol and warming is complex.
Black Soot may dim the sunlight,but may increase the warming by warming the snow.
"A new study found that emissions of soot, or black carbon, alters the way sunlight reflects off snow and may be responsible for as much as 25 percent of observed global warming over the past century."
Wikipedia> Soot forms during incomplete combustion from precursor molecules such as acetylene. It consists of agglomerated nanoparticles with diameters between 6 and 30 nm.
So yes, soot are nanoparticles, but that doesn't mean all nanoparticles are soot.
Simple. We all walk in the middle of winter four hours to and from our unheated homes and offices and work by candle light. Also candles cost 45$ for the carbon offset.
