Hydro plants in cold regions usually have an "ice laying" period where they reduce the output to form a thick layer of ice at their desired level to enable the flow they need and prevent ice-slush from entering the turbines. Seems

Generally people do not pay extra for faster deliveries, that has never penciled out. If you need it fast you spare no expense and use air freight. For the rest it is all about cost. Your scenario can happen if the nuclear setup cost less t

The ship in the article is a Ro-Ro car carrier. No cranes required so the optimal vessel to start with.

Nuclear powered ships would be to putting a crew of ~20 low cost workers assembled from around the world with the inherent communication barriers that brings responsible for a reactor. That does not sound feasible. Regarding sailing, scale

Also, I think every car I have driven in Europe has a knob to adjust the height of the headlights. It seems like it is a requirement, but it might not be. On the other hand, a 2007 entry-level Skoda Fabia would not have it unless forced by

In the Nordics, in December we had the 3 largest reactors out of 11 out of commission combined with a cold spell. That was a nicely expensive week.

That study is useless from a system standpoint. Sure it is a bit interesting to look at the basic facts, but all energy systems are more complicated. For example it only mentions the world "sector coupling" once in the discussion,

You can increase their peak power production to deal with the variability. For example this hydro plant, about the size of a nuclear reactor, maxes out at ~1 GW while the production is on average 250 MW. In other words, it facilitates renew

Or just take any hydro electric dam. The Swedish hydro power currently stores 17.7 TWh. It is not a battery in how it can fluctuate due to natural flow concerns, but some fluctuations are fine.

The problem is taking the most expensive power source with a large portion of the costs being the initial investment and then not running it 100% is economical suicide.

The marginal pricing mechanism is near impossible to change on a market made up of multiple players. Unless you want to fundamentally alter the market to a more monopolistic market where the state selects or owns the power generation. Like

For 100M you get huge solar farm ready to go in a couple of years or 1/100th of a nuclear plant which might come online in 15. Investing in Nuclear is in reality prolonging our reliance on fossil fuels.

What you will accomplish with trying that is that producers will bid what they expect the price to be, instead of their production cost. Thus we still get the marginal cost like all other raw resource markets, but with extra complications.

AWD really does nothing, it helps with acceleration but that is the easy part. The hard part is slowing down and all cars brake using all 4 wheels. You don't brake better with an AWD car. Well, except if you have learned to drive using
