A path to really cheap energy
- You might be amused by this:
I have identified a positive economic feedback loop between beamed
energy propulsion and power satellites.
Given an understanding of the physics of lasers for beamed energy and
hydrogen for reaction mass, there is a very strong feedback loop between
the existence of power satellites and low cost transportation to build
The physics and feedback indicates that future energy costs will be
very low. This seems to be inevitable if you build power satellites
at all and take the beamed energy route to power lifting the parts.
The energy cost looks to be so low that solar energy from space will
displace fossil fuels by simply underpricing them. (Half or less.)
Very low cost space transport is a side benefit.
Further, with only a ten percent feedback, that is dedicating ten
percent of new power sats to propulsion, the construction rate triples
every year, offering the possibility of ending the fossil fuel era in
The minimum investment to reach the self sustaining scale is not
precisely known, but seems likely to exceed $10 B and to be less than
$100 B. A lot of money but not considering the profit to be made
solving a really big problem.
I can go deeply into the technical and math details if you want to see them.
