GROVER CURES HOUSE posted:As extremely poisonous heavy metals, yes. Anything highly radioactive will stop being highly radioactive very quickly because it's highly radioactive. I don't think highly radioactive material is more dangerous than low-radioactive because of some perceived Elephant's Foot instant death. The less radioactive, long half-life stuff can be extremely deadly when it is allowed to spread into the environment. It's not exactly something you can immediately produce "yeah this is really bad" results for either, but when any kind of ionizing radiation gets into a human body, it can have devastating effects.

A plutonium bomb (and my information is a few years old so if I'm talking poo poo please correct me) would be an implosion type warhead. Plutonium only goes critical if it's compressed quite severely with a number of simultaneous explosive charges, and the timing being off by even the slightest amount would radically reduce effectiveness, if not completely fail to detonate. Plutonium is relatively easy to acquire, but the technology to make a bomb is "space is hard" complex. To contrast, you could probably make a gun type warhead using weaponized uranium using two cannons and a chunk of uranium 235, the compression requirements are much less strict. However, refining weaponized uranium is "space is hard" complex. Most of the Manhattan Project was just producing uranium 235, and we only wound up with enough for one weapon (fun fact: Hiroshima was a live beta). I highly recommend this lecture, Physics for Future Presidents if you would like to learn more about the mechanics of nuclear warheads.

Am I right in thinking a lot of the hysteria around the perceived dangers of radiation being based around the whole Radium craze of yesteryear? Radium is pretty loving horrible because your body uses it as it would use calcium, so if you ingest it (which a lot of people did, via crazy radium quackery) it will seriously gently caress you up in the long term. A few scientific studies have come out measuring the health effects of the Liquidators in Chernobyl and they generally found that there was no huge incidence of cancer, and those that did may have been down to better screening techniques rather than the direct effect of the radiation.

And that's ignoring any and all possibilities for reusing said waste too.

Things that are cheaper rarely end up being better. I wonder how many solar plants or wind farms could be built with the $100 Billion the US government still had to spend as of 2014 to clean up the Hanford site. http://www.webpages.uidaho.edu/etox/resources/case_studies/hanford.pdf

I will agree that if we keep burning U-235 we will run out in a quantifiable amount of time - luckily U-235 is not the only fuels source available to us, and likely we're well on the way to developing a new set of reactors that don't need it AND don't operate under high pressure restrictions or use solid fuels.

Solar panels won't work everywhere, but more places could implement it. My company is pushing near to 10k employees in a single campus of 20 buildings and the entire campus now runs 100% off grid between our solar farm, windmills, and geothermal heat. Different areas are more feasible for different types of renewables and companies could definitely be encouraged to do more to select technologies that are suitable for their area. Offer like a fixed %off tax credit or something for percentage of power going to your building from renewables. That'll get companies putting it in much faster than trying to push some sort of rigid building code. Plus, governments love handing out tax credits to corporations so it's something that could feasibly be done.

After watching the full length LFTR vid I'm pretty onboard with the idea. It doesn't seem like all that poo poo I was worried about exists with these things, or doesn't exist in large quantities. I like the idea of the consolidation too, solar is really cool but compared to what they were talking with a LFTR it ends up being a net step backwards.

Bedshaped posted:Nuclear fission in it's current form is: The thing about nuclear waste is its highly hazardous, but its also highly concentrated and containable. Coal power also produces highly hazardous waste, but its neigh impossible to contain so we just say "gently caress it, run it through a mostly useless filter so people feel like we're doing something and then dump it in the air". We're far better off with an occasional nuclear disaster than we are with the guaranteed environmental, health, and economic damage caused by coal plants working as intended. Also most of the nuclear waste we produce can be recycled into usable fuel but we're not doing it because politics. Renewables should be developed, but they're far more limited by location and other constraints than nuclear is. Ultimately, even places with abundant renewable energy resources will need other sources to supplement it, and a lot of places don't have great options for renewable energy.

Wal-Mart has deployed and uses huge amounts of renewable energy. They're probably a bigger consumer of renewable energy than the vast majority of countries. That doesn't mean that it makes financial sense for smaller companies, though...they're able to build this because of economies of scale, i.e. they're able to buy things in vast sums and realize cost savings as a result. They use so much energy that they are by financial/shareholder necessity on the forefront of reducing the costs as much/as fast as possible. They're also redesigning long-haul trucks to be more fuel efficient. You can find both of those things via google. In the southwest of the US (where it is only intermittently/rarely cloudy), we're at a point right now where it makes sense for a homeowner to buy a solar panel system if they can afford it or finance it. Solar panels are no longer a product where it's a luxury or you buy it to feel good about yourself. It makes financial sense...albeit with the 30% federal tax credit. Within 5 years time, it is very likely that the prices will be low enough and the efficiencies high enough that even the federal tax credit will be meaningless. Probably 10 years from now for the rest of the country that have cloudier skies. So you can imagine the same will be true for businesses, but slightly faster since they would have large scale advantages. Solar power is a very near-term inevitability. You're going to see it being a standard option on new home construction, etc. The current hot fad in the tech sector is what Solar City is doing which is solar leasing, where a company puts solar panels on your roof at 0 cost that they own, and then they sell you the electricity back at a lower cost than the utility. It's a great idea for those who don't want the upfront costs, although most homeowners with good finances are much better off buying the systems outright. What Solar City is doing (and other companies have followed suit) could very rapidly speed up the transition. As to nuclear, there is no doubt that we should be building nuclear plants by the dozen. They're cheaper and cleaner. Disposal is mostly just a political bogeyman of the NIMBY variety. Those against it have such poor objections that they come across sounding brainwashed. It boggles the mind that many greenies are standing in the way of it. Been that way for a while now. Speaking of fission, on the topic of fusion, Lockheed Martin has said they will try to have a prototype fusion power generator by 2017, with goals to begin making them for sale in 2022. That's another thing to pop into Google. The energy future is exciting and American ingenuity is mostly leading the way

Are you really equating the damage done by the very first production of nuclear weapons to a modern breeder design that produces a small amount of relatively short-lived waste? And even that 'waste' has medical and space exploration applications. It's hard to take anything you say seriously after that.

Can you imagine private oligarchs coming together and saying to each other "we need to make sure that we invest ahead of time to properly make sure that the american people never have to experience the horrible disaster of the stagflation 70's. Not even a Hyper-Keynesian government will be able to help the poor people who will desperately deal with unemployment and inflation at the same time. This will significantly drive down the cost of labor, and we the oligarchs, who bribe the american government, must help prevent this, a decade ahead of time."
