I have not calculated the acreage required to charge a 7SSSS because there's zero space available where people would want to be getting their swaps = busy roads in cities. Out in a desert where land has zero value is where the photovoltaics would be installed. The existing and upgraded grid would deliver the voltage. With photovoltaic panels in a desert, they would add value to the land by providing shade and electricity to pump water, recharge harvesting machines or provide habitat for fauna/livestock. By providing an instant sink for photovoltaic production when the sun is full glare coming out from clouds, the price of recharges would be reduced. A huge stack of batteries provides a buffer which is crucial for the economic success of electric cars and also for grid use. Elon Musk tries to separately sell huge stacks of batteries to generators with no purpose other than a buffer. Bad idea. 7SSSSs is where the buffer should be, with the charged batteries being swapped for empty. If the station is getting full, they could sell a special = 20% off your swap for the next 2 hours. Car operators would get a bargain and more low cost electricity could be stored. So the mobile fleet would become a buffer too. People would learn when they could get cheaper recharges. With enough saving they'd swap a 3/4 full battery for full. I guess readers understand they'd pay for the difference = computers can do that in 0.1 seconds including after they've left as the process would be all electronic = no cash taking half a minute to waste time on, no credit card drama. People would pay say $100 or $1000 or $10,000 for a rental company, and drivers would show up, transponder ID, 10 seconds later they'd have accelerated back to 100kph (in a Tesla, Lucid, Taycan), ... oops, no, wait. Error. A little battery cannot provide the power needed for 0 to 100 in 3 seconds. It would take 10 seconds maybe. Possibly 7 for a little, lightweight, city car. Heck, maybe 3 seconds for a small well designed one. But cars could have 4 modules, so they could be full power full 800km range. Leave 3 empty unless doing a long trip. Mqurice
