Why would this be dumb?

You only have to warm them up long enough for the ice to melt and run off once for each time they get ice on them.

Plenty of energy falls on a patch of ground each day to melt a layer of ice off of it. Several of times over, even on cloudy days. The reason it doesn't do so consistently is that the energy isn't delivered quickly enough to the ice, so instead a large amount of cold air is warmed slightly. Additionally, ice reflects the sunlight.

None of the people I interviewed have given thought to recycling or handling of the panels, most likely because it's a problem of the future.
People who buy, sell and the government itself, no one has any policy or plan for it.

Silicon based panels are 80% glass and a bitch to recycle. You can crush and remelt it but eh.

Germany is rocking the area, though. Second most Wp per cititzen in europa and they're about to sign a government law where you can return old PV panels for free to the manufacturer.

Also, asia will buy more than 50% of PV panels worldwide over the next couple of years.

And as a note, thin film PV is more "sustainable" than silicon based panels but in decline from an already low market share.

Not the germtard. But no that's patently false. Even the most efficient thermonuclear weapon are below 20% fission rate, and secondary fission products can still be radioactive, and neutron activation can create secondary radioactive compounds.

But the total mass of radioactive compounds in nuclear weapons is far less than you load into a reactor and the explosion vaporizes everything into a fine mist that's readily dispersed and blend into background radiation after a while.

Radiation dangers are severely overhyped because people are entirely clueless, but neither pro-nuclear or anti-nuclear ignorance is going to improve the standing of nuclear power, accurate information is what's needed.

The zirconium cladding can burn, but that would've already happened if you've had a meltdown. The main reason you want it cool is that if left alone it can fully melt and become an ultra hot corium lava if the fission rate is high enough. And this corium blob will melt through steel and concrete and everything else and if it drops into a cooling pool or anything like that it creates a rather nasty steam explosion.

>luckily for the japs
I'm sure those fancy safety features called CONTAINMENT vessel had nothing to with CONTAINING the mateirals, was probably all luck that someone had put a massive structure in place to contain the core in case of failure.

You seem to believe that a BWR with a containment structure can become a chernobyl unless you have luck, this is patently bullshit.
The chernobyl reactor was uncontained with virtually no safety feature. When the core meltdown happened and the subsequent steam explosion happened the graphite moderator was explosively ejected through the reactor building roof.

The safety features of chernobyl was nonexistent and it was a different reactor type, fukushima had them in place so thinking there could've been a chernobyl style release is plain bullshit.

>prevailing winds
prevailing winds are prevailing, there's not much change in them.

Fukushima Dai Ni(fukushima 2, 4 reactors located elsewhere in fukushima province) had more modern safety features(1 was the oldest reactors in japan), but it also lost it's diesel backup power in the same fashion. They had steam driven circulation pumps that can emergency cool the reactor core even in the absence of total power failure. They managed, said it was close to meltdown but nothing comparable to fukushima 1.

These reactors started construction March 16, 1976 and they managed.
