The powerpaste is magnesium oxide. One magnesium atom weights around as much as 24 hydrogen atoms. Thus for every hydrogen molecule you have to carry around 13 times the weight in magnesium oxide. Aka: This stuff is very heavy . Not exactl

This is the wrong question to ask. Hydrogen is not for use cases where there is an electric alternative. Electric almost always wins. But there are use cases where there is no electric alternative or none that is available any time soon, mo

This was pretty much the idea of back then Ecuador's president Rafael Correa with the Yasuni project. Most of the rest of the world said "we won't pay".

Given Juniper released basically nothing about their investigation, I'm not convinced this is a valid example. Notably, I'm not just asking if there ever was a bad commit that was investigated - but that the commit came from someo

I don't like Microsoft, but you can't blame microsoft for the fact that apparently the git project never made a proper webpage. Obviously that means people will try to find information about git elsewhere.
