The next 5-10 years in tech is going to be, rightfully so, greatly reoriented towards sustainability.
I look forward to a time, perhaps beyond my life, when this is not required.
Sustainability is a thing because we know that there is only a finite supply of hydrocarbons in our planet, which are becoming increasingly hard to extract. On top of this, using these fuels negatively impacts climate.
The closer we get to the source, the better things becoming.
Fossil fuels and hydrocarbons are 3rd-4th order Fusion. Fusion > Solar > Plants/Animals > Lots of time > Mining > Burning > useful.
Hydro is 3rd order Fusion. Fusion > Solar > Heating/cooling oceans > Water flows > Dams > Generator > useful
Solar is 2nd order Fusion. Fusion > Gamma Rays > Solar Panel > useful
Fusion is fusion, with no reliance on the sun. Once we crack Fusion, the game changes.
