suggests the sun has no effect on climate.

Or, that we we cannot presently correlate sun and climate. Or there is
some interfering data swamping a comparatively small effect.

If not the sun, how about our dirt? It lives, excretes, and is deep,
to boot. Who understands zero gee fission? we are ice on a fireball.
We are the snowball surrounding hell, walking around on a little
insulating frozen rock floating on a lake of magma.

Cheap renewable power? Geothermal, solar steam, wind, tidal.

Real expense? Transmission, overpopulation?

Private planes to eliminate highway congestion? The highway, be it
asphalt or air, is no more than an extension of the parking lot. Are
we gonna have sky garages 20 floors tall and elevator parking for
excess idle Mohler sky machinery, or are we gonna take air taxis? How
many pedestrians squashed by crashing cabs before we try dirigible
busses, or living with parachutes in our office?

I see city buildings before commuter conveniences. Land is limited. I
see deep wells for Icelandic power, even air conditioning. I see tube
trains surrounding volcanic artifacts linking ring of fire hot spots.
I count the calories produced by cities in their warm spots with their
reflective sky scrapers and steam pipes warmed by moving lightweight
reflectors.

I see wind power to produce compressed air, liquid nitrogen and
ultimately, hydrogen to be burned on site to put power into the grid
when needed.

Can liquid nitrogen be used to operate a Stirling cycle engine or
turbine warmed by ambient air? What is it's energy density next to
gasoline or hydrogen? What about it's seasonal efficiency?

Our oil problems are really political marketing.
