I read where a group studied the environmental effect people had on the environment and that large cities on a per person basis come out on top as compared to people with rural lifestyles.

Are you saying that city people had a larger or smaller per-capita effect?

Per-capita the city people have less impact. I think the study was for New York. Found it.
The Greenest Place in the U.S. May Not Be Where You Think
Green rankings in the U.S. don’t tell the full story about the places where the human footprint is lightest. If you really want the best environmental model, you need to look at the nation’s biggest — and greenest — metropolis: New York City.

On a local note, this week's high and low temperatures from last year. -7/-16 , -14/-19 , -14/-21 , -4/-14 , -20/-24 , -18/-23 , -18/-28
Other that a few days here and there we really have not got below freezing (0 C for our American friends) in the daytime since fall.
It is nice getting a break from winter but it is worrying. There is just a light sprinkle of snow on the ground now and I can see my neighbour's grass where I should be seeing about a foot of snow.

Thanks for clarifying. My mind thought “probably not in Africa”.Per-capita the city people have less impact. I think the study was for New York. Found it.

What do you think they are trying to do? Are they trying to win back customers with that deal or are they treating you folks like suckers?

I think they are trying to identify people like me that are no longer interested in a Cybertruck. and to clear some of the Millions of trucks on back order. and also clear some of the unsold cars que'd up on their production line.

Can I put that down as "treating you folks like suckers" on my "what Elon Musk did today" Bingo card?

I made my cybertruck reservation in the first hrs of tesla taking orders, so I have a place near the front of the line. I will look into whether or not I can sell my reservation to someone who ordered a truck later and is not wanting to wait. Or I may just take delivery and sell to the highest bidder. Tesla has millions of these trucks back ordered..

The Man Who Could Finally Solve the Geothermal Puzzle
The huge potential of geothermal energy to meet the climate and energy crises has always been outweighed by its problems. With Eavor, John Redfern believes he’s found the solution.

Does not say much about the technical aspects other than they drill into hotter rock. Their answer, conduction. But that is no different than a normal geo loop.This is a good read.

Our geo holes were 100’ and loop temp was 50F in winter. Even that allows for appr 3x cheaper heat then resistive. 310F is amazing

The reason the depths are hot is because rock is a pretty good insulator. It will be interesting to see what the Bavarian project’s “available power half-life” will be. The equilibrium when the boreholes have made thick shells of cooled rock around themselves probably will be too low in power to support pumping.
As an extreme extrapolation, if this tech takes off and we pull terawatts out of the continental crust over generations, we might discover that cooling large parts of that crustal rock has unintended consequences. Global Warming might be joined by the calamity of Crustal Cooling.
One scenario I find only mildly fantastic would be that chilling the rock in seismic regions might temporarily freeze major quake activity. The strain will still accumulate, so when it finally breaks it’ll be a doozy.

I thought of the rock cooling and it may cause quakes. Same as fracking, who would have thought it would cause them? Maybe it will get us until fusion is viable.Are you subbing for DIY?

i know we get small little quakes down here cause of fracking, especially in west texas...

Fusion has the singular advantage that you cannot power a planetary cruiser or asteroid habitat on geothermal.

Planets are not the future imo. That’s a key failure of man-child’s plans for Mars. Let him go from cradle to playpen while the bigger, smarter kids take the high ground: asteroids, comets, places with a low delta-v penalty. Then charge the red rabbits an arm&a leg for deep-space commodities.

Too much radiation to content with unless shielded by a big chunk of rock. I assume people will be living Flintstone like on mars or underground. Maybe brief contracts to do the mining but I doubt people can be exposed for years to the extraterrestrial hazards.
