Global warming will be accelerated by cheap free energy. The world will burn out even faster! You people are not physicists and do not understand that the problem is much more complex than you imagined or possibly can imagine. The problem is too many people in too small a space. Either you kill most of the people or you find a more happy solution.
The more happy solution is to harness the "dark" "cosmic energy" like
General MacArthur commanded at West Point in 1961 in his "Duty, Honor,
Country" speech. This will allow us to "part the Red Sea" like a
modern-day-Moses, to make huge Star Gates to transport most of Earth's
population to virgin Earth-like planets for colonization in "Manifest
Destiny" - that's the real story here. It's either that or everyone
dies on this choking sputtering planet.

Jack wrote: Caryn You did not read what I wrote carefully. I am talking about the complex problems of ecology - that a supply of cheap energy will not solve our problem, but will hasten the destruction of the planet because of two factors
1) over-population
2) second law of thermodynamics still applies, i.e. dumping of waste heat between two positive temperatures in all engines in use today.
People like Greer do not understand this.
(Now
one may ask about electric motors, but currents in wires generate
heat unless we have high
Tc superconductors.)

living in this small space at same energy consumption level we "privileged" do

technology and even if we did, practical economics & politics would prevent
us from mass-producing enough for everyone to make a difference in time.
There is one loophole maybe. If you connect a negative temperature to a
positive temperature there is no waste heat. All the heat converts to
work.?
Basic heat engine efficiency is
Work Done/Heat in = (Heat in - Waste Heat out)/Heat in? is limited by 1 -
Waste Heat out/Waste Heat in = 1 - Tcold/Thot
Any negative temperature it turns out is hotter than any positive
temperature, therefore in such a quantum "over-unity" engine
1 - Tcold/Thot = 1 + |Tpositive/Tnegative| > 100%
That is, heat is sucked out of the cold positive temperature reservoir to
get over-unity. If the negative hot temperature works with zero temperature
vacuum it's a zero point energy engine as a special case. There is no actual
violation of 2nd Law of Thermodynamics - it's a new non-classical regime since
quantum theory allows negative temperatures from quantization of energy levels
of bound systems.

You were talking conventional engine; I agreed that something else is required. If we don't have the ability to produce that in time we sure as hell won't be achieving warp-drive and star-gates in time.

SMI^2LE
SPACE MIGRATION through stargate wormholes, otherwise The Reptoids will have a super-harvest with billions and billions of us. Time to get out of Dodge.
You need to control dark energy at small scales to achieve this. This seems
to require the Russian torsion field concept.
