Spacex have already succeeded with Falcon 9? Starship is the next magnitude in cost reduction following the same formula.

Rather, it is incredibly easy to overspec. Everything is important and then you get SLS like costs. Compare to Falcon 9 which took a similar path to Starship and today works beautifully for human launches. Take the SLS crawler looking to co

They had done static fires at half thrust, equaling the thrust Saturn V produces without issue. Why spend hundreds of millions or in the case of Saturn V billions on a governmentally overspecced launchpad when a launch mount and a concrete

The thing missing from your conclusion is simply combined cycle gas plants. Take an airplane engine, benifiting from that huge industry and add a tiny steam side and you have something way smaller, cheaper and more efficient than any coal p

France has been importing energy and driven the energy crisis in Europe because over half the fleet has been offline. You also talk a lot without addressing the central point: the energy market in Europe is based on marginal price. Please,

Your hanging everything on "24/7". Take a look at the numbers in the report for firming renewables and contrast them with nuclear.

You should learn about the time value of money. Money today is more valuable than in 50 years so you can't simply ignore the high upfront cost because it makes nuclear impossible on any open market. https://www.investopedia.

Framatome is owned by EDF. > Framatome (French pronunciation: [fʁamatɔm]) is a French nuclear reactor business.[1] It is owned by Électricité de France (EDF) (75.5%), Mitsubishi Heavy Industries (19.5%), and Assystem (5%). https:/

EDF bought the bankrupt carcass of Areva to preserve the French nuclear industry. The construction is kept in a separate company, but the French bore the losses.

The French tax payers have through EDF taken a loss of €5-10B on Olkiluoto 3. Definitely cheap, if you make someone else pay.

That is missing the forest for the trees. Yes, there are scenarios where a heat pump is not optimal, but the point is not to fix it all tomorrow. It is to solve the 9X% while creating new industries enabling the last more challenging applic

> Let's ignore the earthquake and tsunami that happened and pretend that all that cleanup is only due to Fukushima. Typical nuclear proponents, trying to shift blame. The $2T is for the nuclear side of things.

We can agree that 90% is trivially solvable. That will get deployed shortly. So you are telling me that a peaking nuclear plant will solve the last 10% when it comes online at earliest 2040? What problem are we even solving at that time oth

Let's fix the +90% that is trivial without storage and work on the last percents when we get there in the 2030s. The research finds it easily solvable today, but a holistic approach is necessary. https://en.wikipedia.org&#x2
