Hydrogen is a storage medium. Fossil fuels are used as the energy source to make the rocket propellant.
I can also guarantee you that fossil fuels were used in the production and distribution of the rocket boosters and that the airplane the video was taken from wouldn't be flying if it didn't have any jet fuel in it's tank.
Humans are smart creatures, but we shouldn't kid ourselves into thinking we would be where we are at now if it weren't for a cheap, albeit limited, supply of highly concentrated energy.
- kirubakaran 16y agoBy that logic, fossil fuel is a storage medium too. Solar energy was used as the energy source to make fossil fuel.
- aarontait 16y agoTrue, with the difference being humans (and our predecessors) had to wait hundreds of thousands of years for the fossil fuels to form under the immense pressure (and additional energy input) of the earth.
- dtby 16y agoAnd you believe that the value of this observation is what, exactly? That we are wasting energy which has been stored and untapped for hundreds of thousands of years? Do we really expect that our ancestors will be better able to exploit this value than we are... without our given expliotation? Will this be true forever? Should we just let that stored energy remain forever? Ceteris parabis, we will extract exactly as much value from our ancestors as makes sense. And our ancestors will do exactly the same. I do not begrudge them that any mire than I begrudge us this current state of affairs.
