1: The particle collider was never intended to support fusion as a viable energy source (That would be ITER)
2: This is very cool although myon catalyzed would be infintely cooler
3: We will get some form of cheap and emission free energy within the next ten years, the question is just which contender will be first to commercialize their technology (it takes much MUCH longer than you think and the building of serious MW plants is a pretty daunting feat.)
4: The major problem going forward will be how we can build the next generations of batteries with materials that don’t run out wuickly.
