Nuclear power

How about instead of copper, monocrystalline silicon?

Wafer (electronics) - Wikipedia
Wafers are formed of highly pure,[6]nearly defect-free single crystallinematerial, with a purity of 99.9999999% (9N) or higher.[6] One process for forming crystalline wafers is known as the Czochralski method, invented by Polish chemist Jan Czochralski.

Maybe 0.1% in the control circuits for hydro?

When you count materials used, deaths caused by, CO2 and land use there is only 1 clear winner and a very clear loser, well maybe 2.


Nuclear is the lowest. Lowest death, lowest pollution, lowest land use.
Hydro is pretty good too but we just can't effectively build any more in the US.
I have heard solar can be as high as 2 or 3 deaths per TWH when you count people falling off roofs f'in with solar panels, installing them, cleaning them ect.
I'm not counting land use for hydroelectric because the numbers are all over the place, we need the water, people seem to like lakes. I have never heard anyone complain about a lake ruining the scenery. And it's not like we are going to build any more huge hydro dams in the US. My understanding of hydro electronic growth in the US is coming from adding generation to existing dams, pumped hydro and slapping a hydraulic motor on the end of a piped aqua duct.
Hydro is actually pretty dangerous. A hydro electric dam in China broke in 1972 I believe and killed unto 380,000 people, more recently in 2017 the Orville dam was a few inches of rain away from washing out the spillway and clasping that dam. It caused at least a billion dollars in damages to the dam.

I would say coal is definitely the worst and solar is pretty bad too based on land use and resource use. Coal is so bad why is any nuclear super power even using it at all?
Wind is not really that great either.

Your markup is indecipherable.

I don't disagree with your conclusions in general; maybe coal isn't as bad as firewood and dung?

Wind and solar are a design problem waiting for an optimal solution. The tides will continue regardless.

More is bad.
More death, bad.
More plant food, bad.
More land use, bad.
More resources, bad.
The only one with the least of all those is nuclear.
Here is an representation of how safe forms of power are.

So you've congregated your power into a centralized location. What then? Powerlines are vulnerable to CMEs and Gamma Ray bursts. Comes now https://earthgrid.io/plasma-tunneling/

Can they leave The Boring Company in their dust? If a sense of humor is necessary, then yes; their acronyms are:

B.O.O.M.™

Build, Own, Operate & Maintain — B.O.O.M. — is for customers who prefer to sign a long-term lease or tolling arrangement covering the commodities flowing through the EarthGrid tunnels. (EarthGrid will cover 100% of all costs for development, construction, operation, maintenance, etc.)

B.A.D.A.S.S.™

Boring And Drilling As a Simple Service — B.A.D.A.S.S.— is designed for customers who want to own their own tunnels. EarthGrid provides the tunnel.

Centralized is easier to manage.
Australia is about to spend billions of dollars to revamp their power grid so it works better with highly variable power sources. That's more resources, money, land use that isn't counted when figuring wind and solar.

Centralized is easier to manage control.

Australia will likely drop billions into obsolete thechnology. There're people making graphene power cables now. Those should be in underground plasma-dug tunnels.

Recently some optic-fiber internet cables caught fire in a nearby borough due to overheating. Makes me wonder how a graphene cable would cope better with such conditions.

I wish I had the problem of my fiber company being on fire. Instead, I've had my cable box open and exposed to the weather for over a year with no fiber being installed. I think government is paying them to pretend to install fiber.
