What I meant is ofcourse de-carbonise economy, Singapore can't be energy independent in meaningful sense as it does not have fuel sources of any kind. And solar/wind do not count as there could totally be still nights. I frankly d

I am all for pursuing fusion, for pushing borders of our knowledge. At the same time, concerns are way overblown about fission. You know, it is regulated to 1/10000 amount of radioactive increase that is known to ever cause harm. This

To add to your list of currently available proven approaches, would an approach that decarbonized France's energy in just 10 years should also be considered? It looks like proven track record of decarbonisation if there is one.

Well, one example. I live in Singapore, and for it to become energy independent, it would need a square kilometer for a nuclear plant. To achieve the same with solar, you need to pave the whole country with solar panels. Besides, to make th

nuclear energy density is derived from e=mc2, so fusion/fission are in the same ballpark. Current accepted way is to build solar/wind and redesign grid to deal with intermittency. Solar and wind are even more energy diluted than f

The fundamental difference between nuclear and any other source is energy density. It boggles ones mind that your can replace burning 14 thousand tonns of coal _every day_ with something that needs to be refueled once a year.

In this particular case, they are planning to take energy from carrier's nuclear power plant. More generally, either hydrogen or fuel synthesis requires energy to come from somewhere; In this regard it is no different than re-building

If my understanding is correct, the goal is to reduce aviation effect on climate change. There is an ongoing project [1] by US NAVY to turn seawater into jet fuel. This way we would not need to burn fossil fuels and would not need to throw

The point is to be able to have way less exclusion radius, not 10 km but 500m, as nothing will fly out of there. Chernobyl occured because of graphite/fuel configuration went wrong. In this fuel it just cannot go wrong as it never chan

It is for use in reactors cooled with gas, so there is nothing to boil up and explode. And higher temperatures allow for smaller and more efficient reactors. Smaller also means cheaper.

The reason for nuclear is that it has proven trackrecord of decorbanizing an industrialized economy. [2] As for the waste, it pays to extend 'relative' - nuclear leaves a coke-can size of waste safely stored on site for a person&#

The difference here is that you test everyone entering a certain location, not everyone in general. This is much easier, and allows testing to be focused on most needed areas. In effect, if you only go to the groceries once a week, you will

Solar and wind are fine for residential, which is 13% of global consumption. Transportation and industry, with their 75% , would need some clean source of energy, for which calm nights are not a problem, crony capitalism or not.
