Coal plan produces more radioactivity than nuclear plant. There are radioactive elements in coal and they get released in smoke into atmosphere.

This old one again. As someone who's actually worked in the nuclear energy industry, it's a common but wrong refrain... diffusion of petrochem radioactivity is much less of a liability than the very real, concentrated dangers of radioisotopes, even factoring in all of the other many negatives of coal.

Nuclear Fission is not a plug and play solution either. Unlike other possible solutions like a breakthrough in mass energy storage, we know that fission could satisfy our needs. But it will still require some 30 years of investment to figure out the new breed of reactors and where to source the fuel from.

It can be if it's standardized as Taylor Wilson suggests... build uniform, low pressure, high temp molten salt reactors in a factory.

Forgive my skepticism, but Mr. Thiel did not offer to live near a reactor. For someone with his obvious intelligence, his oversight could not have been accidental. Does he fear the radiation or the decline in property value? When a robber baron like Dale Carnegie wanted people to believe in his steel bridges, he staked his life and reputation and walked across the damned bridge. Another major risk not mentioned by Mr…

> Forgive my skepticism, but Mr. Thiel did not offer to live near a reactor. Living next to a coal plant is even more dangerous than a nuclear plant, are you suggesting we should ban both plants based on these considerations?

Actually the late USSR had a technology of small fully automatic single loaded reactors for long-term supply of electric power in middle-size cities. Fully sealed unit. After use (decades) - you just cover it with a lawn. But back then the USSR had enough fuel in production. Right now the know how in Russia is lost and nuclear fuel generation is very weak. Also HMD generator by Oleg Gritckevitch was very promising. The town in Armenia was fed by electricity generated by a small prototype in 1988.

I am afraid that the real goal of at least 50% of climate change activists is not clean energy, but the disruption of current elite and wealth redistribution by taxation vs value creation. It is because of these 50% the realistic proposals like Peter's will not fly politically.

In my country, green organizations, including the local branch of WWF are nothing more than extortion artists. They rally young, impressionable people by spreading FUD. They block ski lift projects and drum the media on all sorts of nonsense and broker their power to influence current political agenda or for money (when they run out). Most were created by ex-intelligence slightly before or after The Wall fell. It's d…

+500. WWF, SSNC, Green Peace they are all selling FUD for a price 'one p#ss for one green piece'.

Absolutely, but don't discount the FUD. Much as people fear an airplane crash more than a car crash, the prospect of nuclear power is far more terrifying to most than just another coal plant. It's not enough that the coal plant is orders of magnitude more deadly, it's the perception. Even the image the NYT used will convey to many a disregard for life, pumping harmful radiation into our environment, rather than merel…

I think the big fear of nuclear power is because we don't know how to handle catastrophic risks. With coal power you will have a few dead mine workers. It's only mine workers that are affected and they have a definite risk in front of their eyes. You can rise the worker protection regulations for making this safer. You have the problem of air pollution through fine particles and sulfur. You can solve this with filter…

Why is it that Fukushima isn't an argument _for_ nuclear power, considering the plant even closer to the epicenter came through with flying colors?

Thiel skips the fact that Chernobyl is uninhabitable for thousands of years (save bloggers on motorcycles), all of the dispossessed persons and extra 40k+ cancer deaths. Plus Fukashima. Big PWR/BWR reactors will always be too inherently dangerous because of high pressures and too expensive to build, regulate and insure (in the US, without insurance and NRC approval, there is no project). And the risks of dual-purpose reactors and long-term storage for large amounts of waste.

Taylor Wilson's TED talk on low pressure, molten salt, modular reactors built as standardized modules with a scram / recycle pool underneath and made in a factory is one of the best ways to go. Smaller, isolated, modular setups limit failure risk compared to a single reactor having a big, explosive meltdown. The other one is thermal generation using chip-like technology with tiny amounts of radiological material isolated in individual "wells" making it safer, more efficient and scalable for many types of battery and generation use-cases.

I think we can do fission safer, cheaper and smarter, responsibly, but repeating the same failures by taking the same risks without learning from the past is inherently dumb.

That would be Andrew Carnegie. Dale Carnegie I suppose is more like a confidence man than a robber baron.

Fossil fuel companies have already priced in eventual recovery of their reserves, added it to their value and communicated this to the market (with what incomplete information they reveal). Fighting to keep it in the ground is already wealth distribution. It reminds one of the story where you ask a person if they'll sleep with you for a million bucks, why not 10,000, since you've already established what they are, now you're just haggling over the price.

It is a shame that we went all in on uranium reactor technology (so we could make bombs) instead of further pursuing liquid fluoride thorium reactors, which are much safer.

Kirk Sorensen at http://flibe-energy.com/ has some great talks about this. I highly recommend watching some of his content on youtube.
