Something to think about.
The Alcubierre Drive is being promoted by a project called “100 Year Starship”. Their goal is to achieve an interstellar mission within 100 years from their founding in 2010.
A faster than light interstellar starship will not be powered by solar, wind, biomass, or batteries.
At a minimum, nuclear fusion is required. More realistically, antimatter power is required.
If we can build an Alcubierre Drive powered starship in 100 years, it means we will have solved all of the world’s energy problems well before then.
Robert Goddard launched his first liquid fueled rocket using gasoline and liquid oxygen in 1926. It would be another 31 years before launch of Sputnik 1.
The petroleum fuel industry dates to the mid-1800s, roughy 75 years before Goddard fueled his rocket with petroleum distillates.
Realistically, an Alcubierre Drive powered starship is more than 100 years away, but equally realistically, energy from nuclear fusion is closer than 50 years away. And cheaper, safer, advanced fission is less than 20 years away.
Where do you want humanity to be 200, 100, 50, or 20 years from now?
I just don’t know how going backward to windmills and burning wood (biomass) gets us to the future.
Oh please we have only got 11 or so years left
