Following the conception of a Transatlantic power cable, I just heard on
the radio that a couple huge globe-ish spanning electrical-busses are
under planning... one that might span from Thailand to Saudi Arabia
(through northern India) with Solar (and other renewables?) tapping in
along the way and load-shifting E/W with the sunlight and load. Also
maybe one that spans Australia which I believe to be about as wide as
the US?
Seems like TX's problems stemming from their own (short-sighted?)
self-isolation might be good hosts/promoters of such a long-throw?
I don't know what it would take to upgrade the national rail system to
also be a load-balancing shadow network for renewable electricity? I
assume none of them are electrified (third rail) but maybe laying one,
given the pre-existing right-of-way and regular
inspection/maintenance/access available would be of interest? But then
maybe our FriAM member who is working on converting natural gas to
pneumatic energy-transfer/storage knows more about all those issues?
Hybridized infrastructure across many types?
Maybe the existing Diesel-Electric Engines (most of what is on the rail)
could tap in mildly to reduce diesel consumption and do their own load
leveling? Fill empty tankers with water at the top of lines (where
there *is* water) and carry it to low lying land, extracting the PE from
the mass/elevation drop? Reline old asphalt/fuel-oil/etc tankers and
provide boutique "Rocky Mountain" (or Cascades) branch-water to the big
cities while extracting (maybe) enough energy from the elevation drop to
at least pay to haul the damn empties back up the hill?
With me as the big "unintended consequence" chicken-little, I'm sure
most if not all of my hare-brained schemes are truly just "asking for
trouble", but I think it is inevitable that they will all be considered
in the spirit of adjacent-technical-possibles...

This fusion video should be the standard for how to present every
single technological innovation, every so-called "renewable energy"
device that is too little, too late, and most importantly distracts us
from thinking seriously about how we shall survive climate catastrophe
and continue to live a flourishing life on earth. Thank you Carl--I
think you sent this link to the group.

I had never heard of a transatlantic power grid. That is an
interesting idea. The sun is probably shining somewhere on the
earth at any given time. Would a lot of energy get wasted with the
long distances?

I like the idea of a large transatlantic DC power cable.
That would enable solar power to be distributed around the
world. It would reduce the need to depend on batteries
for wind and solar. Of course, you raise #3, so it would
be a target for sabotage like with Nordstream. It would
be nice to think there are things just to valuable to
destroy, but probably there are no such things.

What you are missing includes
1) Disposal of long term hazardous nuclear waste.
2) Problems in maintaining / decommissioning ol older
nuclear fission plants
3) Examples like we are seeing Ukraine's nuclear plants
caught up in a war.

Ok so this is cool and all.
Sigh I'll ask /that/ question. We want less carbons
because the planet is on f'n fire
<https://www.youtube.com/watch?v=IFgBFYkBZ6E> . As
far as I know humans (in the very least) accelerated
climate change. Ie we made this mess clean it up. ok
fair so far I'm following.
So uh why not just start with fission (breeders) ? Why
not also put as much money into matter/anti matter as
well as fusion? We can make minute amounts of
antimatter in massive collider. I'd think something
who's by product are xrays gamma and some other stuff
with a lot of energy created would be a massive honney
pot the department of energy would pursue as well.
I know the answer to fission (sadly) is NIMBY. (yes
but it's a lot cleaner and safer than oil and coal I say)
I don't know why we haven't looked at other things as well
What I'm saying is fusion has been humans icarus wings
with it being just arround the corner for decades.
while matter/anti matter is (sort of) here. Fission is
here. Want zero carbons? cool! so why not build out a
ton of reactors we already can do. Or am I missing
something?

I think DT refers simply to the remaining
fraction of Deuterium/Tritium remaining after
the reaction event (-4%) without specific
accounting for remaining D vs T.
My understanding is that D-T fusion occurs at a
lower temperature than D-D but that once fusion
commences (starting with D-T), both D-T and D-D
reactions occurring in similar amounts. In
laser-driven ICF (as with NIF) I believe the
ratio of D/T is nominally 50/50 though it would
seem to make sense to have a higher T to D ratio
but most references I see imply equal
portions. An equal number of D-D and D-T
reactions would seem to consume D more quickly,
though as that commences, the D/T ratio would go
down, making D-T reactions (yet) more
likely... tricky business, no wonder it has
taken decades to get to this point?
The Wikipedia Entry on ICF is pretty good:
https://en.wikipedia.org/wiki/Inertial_confinement_fusion
I found several popular science Articles which
seem to reinforce my sense that this
"breakthrough" is not as significant as implied:

and D-D fusion...

That's why I asked. I guess I'll assume DT
means both deuterium and tritium, not just
deuterium. If you were going to track fuel use,
you'd track the rarer part more closely, right?
