Assuming à 2% annual growth, humanity's entire power consumption will surpass:
- the entire power sent by the sun to earth in 360 years.
- the entire supply of fissile material in about 900 years.
- the entire supply of deuterium in the oceans in about 1000 years.
Andrew Côté@Andercot· 18 août 2023The oceans contain enough fusion fuel to power our current civilization for 65 billion years.
If we assume compounding growth of 2%, how long will it last?
Fusion: 1060 years
Solar: 460 years
Let's dig into the physics of our energy economy.
(warning: math ahead).
