And the levelized cost of PV + storage as per that link is $250 to $600 per MWh. By comparison the cost of nuclear in that study is $130 to $200 per MWh. Thank your for providing this source explaining how the cost of storage renewables at

Correct, we shouldn't use modular small reactors (or molten salt reactors for that matter). We should use the pressurized water reactors we actually know how to build. France generates over 70% of its electricity from them, and the US

Levelized cost of energy in your link excludes the cost of storage. For the third time, nobody is arguing that raw renewable generation isn't cheap. The issue is that translating raw renewable generation into usable, dispatchable power

Academic papers claiming feasibility decades from now is a vastly different thing than something actually being feasible. If it were, then we'd have all been using fusion power since the 1980s. If you prefer a global approach as oppose

Storage costs, despite being in freefall still are still in the hundreds of dollars per kilowatt hour range. And it's kind of moot since the total amount of storage produced globally is still a fraction of what is necessary to make ren

I think Google would be more than happy to take a hands off approach. The issue is that the PR hit for being alleged to "radicalize" people or promote fringe views had becomes smaller than the PR hit of censorship.

As I pointed out in a response to your other comment [1] this is incorrect. Police as a public institution in the US date back to the colonial era, centuries before you claim the first police departments were formed. Altering the statement

Policing in America dates back well beyond the 1800s (let alone the late 1800s), and has it's roots in the medieval system of sheriffs and their deputies. Organized police in the US date back to the early 1600s at the latest. In fact p

Law enforcement had existed for millennia, not the last two centuries. Greek polis had nyctostrategoi (literally, "night officers") that patrolled and enforced laws as early as 500 BC. And Mesopotamian city states probably had p

Liquid natural gas freightliners are also refillable. I'm not sure what you mean by this. A cargo ship filled to the brim with batteries still has orders of magnitude less energy as a ship filled with the same mass of natural gas.

Correct, the sun is a great source of energy. But we use most of our energy when the sun is blocked by the earth. The sun is opex and capex free, but the storage necessary to make it feasible requires massive capital expenditure and massive

This paper just ran an algorithm over a heightmap, and pinpointed potential reservoirs. This is a far cry from actually identifying feasible sites. The massive density of hydroelectric storage in the Himalayas, for instance, is far too remo

Pumped hydroelectricity is geographically dependent - you need a valley or mountain that you can dam up to build pumped hydro. While it may be great for South Australia, the region examined in your linked paper, it's wrong to assume th
