Long distance would be accomplished by DC transmission. Much lower losses than AC.Insolation at the equator is between 380 and 430 W/sq meter (depending on the time of the year) for no more than twelve hours per day
With commercial photovoltaic efficiency available now in the 22 to 26% range, 1kw would require 9 to 12 sq. meters
If you're going to transmit it long distances (like to the US) you need to convert it to a/c and conversion losses can be as high as 30%, or 13 to 17 sq. meters per kw
US total energy consumption in 2019 was about 4 trillion kWh, or about 11 billion kwh per day. Assuming 2/3 is daytime consumption that is about 611 million kWh per hour during that time
That equates to at best 8 billion sq meters of photovoltaics, or 800 million sq meters to accomodate 10% of US daily demand, which is 800 square kilometers or a square 17.5 miles on a side plus room for the infrastructure - enough to completely cover Honolulu more than 4 times over. Where are you going to put it?
Will an equatorial country give up 300+ square miles of cleared land? I think not, esp. since most of that is farm land. Are you going to hack 300 square miles out of jungle (and keep it hacked)? Bon Appétit
C'mon, foz -you should be able to do the math as well as I can. And don't forget that the US will have to come up with the other 300 million or so kWh per hour of demand during the night. Then you have transmission infrastructure running about 2400 miles through countries of various degrees of lawlessness or instability (that distance is Bogata to Brownsville)
Then long line transmission loss is 8% at best, so you need to up your photovoltaic area commensurately, all to take on 10% of us power consumption for half the day.
I'm sure you'll have no difficulty lining up investors
Have you ever been in a powerplant, particularly a coal fired powerplant? Ever stood inside the boiler, repair the wall tubes, slag tank, grinders, sootblowers, ID, FD fans etc.?At the design parameters, slagging is much less. With dirty blends it becomes necessary to deslag more often sometimes much more often.

I have this isnt theory for me, its real life stuff
Nikola Tesla disagrees, their is a reason it AC today. And that is actually transmission capabilitiesLong distance would be accomplished by DC transmission. Much lower losses than AC.
You guys would argue all day long for steam engines in the face of internal combustion. Unable to see the future for the present
Call me a skeptic.
DC becomes cheaper over long distances than AC. That doesn't mean AC isn't more economical in medium distance.Nikola Tesla disagrees, their is a reason it AC today. And that is actually transmission capabilities
OK this is mostly for balance not power supply on a steady basis. You realize this will absorb power as well as this has been explained to me. Frequency control is a new ball game done this way. It is a step up.
Rather just call you Jay.Call me a skeptic.
over the Break Even distance only. and still has limitations, you don't get something for nothingDC becomes cheaper over long distances than AC. That doesn't mean AC isn't more economical in medium distance.
Yes. >60 Hz charge, <60 Hz dischargeOK this is mostly for balance not power supply on a steady basis. You realize this will absorb power as well as this has been explained to me. Frequency control is a new ball game done this way. It is a step up.
thats fine, just don't call me late for dinnerRather just call you Jay.
Ignoring your first sentence, the rest is true. Your conclusions aren't. That's exactly why boilers started having so much slaging issues because bean counters ignored design parameters and started burning cheap ass coal from out west
Precisely. Balance not supply.Yes. >60 Hz charge, <60 Hz discharge
it can't you have to have boosters at a lot closer intervals than AC.....so we must rebuild the grid too???DC becomes cheaper over long distances than AC. That doesn't mean AC isn't more economical in medium distance.
Good Lord, Bug talks about transmission from the equator so I mentioned DC is cheaper over long distance than AC.over the Break Even distance only.
Boosters at a lot closer intervals than AC?it can't you have to have boosters at a lot closer intervals than AC.....so we must rebuild the grid too???
that is not free so power costs go up....
the discussion was about our grid, you didn't quote anything bug said.Good Lord, Bug talks about transmission from the equator so I mentioned DC is cheaper over long distance than AC.
Did you think I was talking about something less than the break even distance?
More likely just wanted to disagree.
So has Biden . . .Well he ain't lying. It's been declining for decades
