I might add that efficient quantum simulations would be immensely useful. So it's worth pursuing research in this area. Results are however not guaranteed.

We do not have efficient general quantum algorithms for quantum simulations. A quantum simulation can be decomposed in 3 steps: 1. a simulation needs to start in a given quantum state 2. from there it's possible to quantumly evolve the

Dealing with vim plus learning to code is hard. And the reward comes later on. It makes sense to start with vscode...

The conclusion: policymakers should be prepared for several metres of sea-level rise over the coming centuries. [...] Limiting the societal and economic costs of sea-level rise will require a combination of mitigation, adaptation and luck.

Guyana and Venezuela are two neighboring countries and they have no roads crossing their common border. Same context: a thick jungle.

My point is that thermal power doesn't scale well. If you need 10x more electricity (growing needs plus electrification of all energy) thermal pollution of rivers becomes a big issue.

Batteries costs and PV costs are both dropping exponentially. So it doesn't matter much. Once batteries are everywhere who cares when the electricity is produced. Hey btw Vermont Utility plans to installs battery storage at customers&#

«The tides are turning in favor of nuclear energy» in their dreams... PV costs are falling exponentially (-10% per year) while nuclear costs remain at best constant. If you decide today to build a reactor it will be ready in 10-20 years (do

Exactly, 100% nuclear is not achievable without storage: nuclear can do baseload but not daily peaks.

The first sentence «Nearly all of our electricity is generated from heat powering a steam turbine» just explains why nuclear cannot scale: thermal power (including nuclear fission) needs huge amounts of water to cool down the turbine. The t

Actually coal and nuclear can only do base load: thermal power plants need hours to shutdown or to ramp up. That's why hydroelectric or gas peakers are needed for daily variations (peak hours). So 100% nuclear is not doable. Renewable

Chemical energy. Like the plants, they take sun energy and store it as chemical energy. We could do the same, take CO2 and water and make CH4 and oxygen (electrolysis + Sabatier reaction) and make plastic. Or take ore, aluminum oxide and ir
