The paradox of tolerance is simply factually incorrect when it comes to speech. The existence of intolerant speech doesn't exclude anyone. People who are offended don't have to listen. The paradox of tolerance only exists when peo

The book mostly focuses on raw generation figures. I see little to no writing on how to handle the intermittency of renewable sources. Also, the 1,000 year figure for fissile fuel does not consider reprocessing which reclaims over 80% of fu

Likewise, Pripyat remains a ghost town because it was planned city built to support the power plant workforce. Now that the power plants are no longer in operation, there's no incentive to clean it up and resettle it.

> That's not 1.5GWh energy stored, it's 1.5GW output from storage systems So how much is actually stored? 1.5GW for 10 minutes? 15 minutes? Watts isn't a unit of storage, watts per a unit of time is a unit of storage.

Th fact that California only has 1.5 GWh of storage is precisely the reason why wind and solar cannot form the primary source of energy. Who cares if the state met it's storage goals if the storage goals were tiny?

Yes, but the cost is spread out over all the nuclear plants in operation. Nuclear energy already provides 10% of the world's nuclear power. We currently average one significant nuclear catastrophe every 20 years. $15 billion every 2 ye

I like framing the problem in this term. Our ultimate goal is decarbonization: $1 million per gram of C02 emitted unless equivalent mass is sequestered. Do we have a realistic plan to built a wind and solar grid under that market? I don

Even a much more modest goal of provisioning a single day of storage would entail 11.5TWh of storage. Dozens of 100 MWh facilities is still in the single digit GWh range. That's six orders of magnitude. And this isn't even taking

To put these in perspective, the US consumes 500 GWh of electricity every hour. Of the 23 GWh of existing storage, 20 GWh come in the form of hydroelectricity. 100 MWh of storage only amounts to 1.4 seconds of electricity storage. We don&#x
