ooo an on topic thread
Apparently it is a DC connection and this is why it needs "thousands of valves". The valves are not valves they are individual power semiconductors in serial to manage the massive voltage and the "fiber wires" are fiber
Why would you even consider nuclear when solar+wind+electrolysis+hydrogen gas plant is cheaper?
No, I just thought a snow storm can easily last 5 days
Ignoring the environmental factors because, you know, radiation, birds, CO2,
A 1 GW plant.
Nuclear about $10 billion to build, varies wildly between countries but $10 billion in a sane country. No back up battery needed.
Offshore wind $5 billion to build plus I'd add at least 5 x $1.68 billion for battery storage
Solar like you say $2.4 billion plus a short term storage $1.68 billion to cover night time PLUS 5 x $1.68 billion for battery storage
Gas maybe $1 billion and lets be fair $2.5 billion for gas storage to last a week (actually a month )
Solar or wind plus gas backup is clearly better than battery backup! I'm surprised, so maybe I made a mistake in the sums there.
Lets go further.
1 GW solar + 1 GW wind + 1 month compressed hydrogen storage + 1 x 500MW electrolysis + 1 GW hydrogen gas plant
$1.2 billion + $5 billion + $3 billion (ignore land use for 5000 trailer sized tanks) + $1 billion for electrolysis + $1 billion = roughly same as 1GW nuclear plant
cuts the lifetime cost of stored energy by an average of $70 per kilowatt-hour. That's roughly half the total cost of a typical battery system today
Do you want me to explain how I worked it out?
To store the full daily output of a 1 GW power station using battery technology priced at $70 per kWh, the total cost would be $1.68 billion.
I think they decided that the 20 year average should be over 1.5 so it is quite difficult to achieve by 2030. The next 3 years would have to be warmer than this year, probably, I think, I guess
What is git gui?
Channeling D.A. for a moment
Why can't our A.I. improve our business?
I guess our minds are just too highly trained
You said : But the state doesn't collapse until YOU join the interaction, and become yourself entangled.
This is untrue, as far as I know.
This seems like nonsense. I think observation is nothing to do with observation but more "making a measurement" It is nothing to do with you looking at stuff.
I don't really get it though. Where does something stop being quantum and start being measured/observed? Is it one electron? Two? Infinite?
I don't think so. The most powerful reactors are under 2GW. They probably meant a complete site. Anyway, the point is 600GWh is about enough to last the USA 1-2 hours. Much much more is needed, if battery storage is the target
This is nothing to do with light speed. It is talking about how quickly mass can fall into a black hole via an accretion disk
This is bull. The figure of $11 million every minute includes about 90% implicit subsidies. Implicit subsidies are like saying "gas should cost $10 so it is subsidized by $7" There is no actual subsidizing happening in implicit subsidies.
Surprise your boss. Get to work on time.
