With 7SSS stations available, people in their Uber autocars will zip in, stop for seven seconds while one battery is pulled out and the replacement pushed in, then they'll accelerate back up to 130 kph in 3 seconds. Good electric cars have super torque from a standing start, unlike sluggish cars such as Ferraris. In one lane of 7SSS one car per 10 seconds could be swapped. That's 6 a minute or 360 per hour. To handle 360 in an hour in the Tesla Supercharger lanes, they would need 180 lanes. That would be the world's biggest service station, bigger than the biggest toll booth lane jam on Earth. And the electricity needed at the peak would be too huge to supply. With 6 lanes, a 7SSS[tm] could supply 2000 cars per hour. Tesla's SSS [Silly, slow, supercharger] would be able to do 10 cars per hour in those 6 lanes. If the Tesla SSS charged 4 cars at a time per lane, they would still be able to do only 40 cars per hour. People sitting in the Tesla SSS would soon get sick of watching people in the Mq 7SSS[tm] pull in then zoom out 7 seconds later. After half an hour of sitting watching that, or an hour if they are stuck in a queue of 2 cars, the Tesla SSS driver will be buying a car that can go in the Mq 7SSS[tm] lane. The Mq car will be much cheaper too as the battery will be a fifth the size, or tenth. And lighter, so less energy would be needed to drive around. And structurally lighter as less tonnage means smaller wheels, lighter suspension and steering, lighter body. At the 7SSS the batteries could be recharged in stacks at off peak times and uniformly at all times providing steady base load to power stations, or when the sun is shining or wind is blowing if those are the energy supplies. The company that figures it out will be the richest company on Earth. They should patent their 7SSS technology and smoothed recharging process. No, wait, they can't. It's public information available to everyone from Mq's public patent portfolio. But wait, there's more. People who have photovoltaics at home or have other cheap electricity supplies will be able to take full batteries to the 7SSS and swap for one with only 10% charge, making money as electricity traders. Your electric car and photovoltaics could be a profit centre instead of a cost. Uber autocar taxis would be constantly on the move, needing regular 7SSS recharges. Delivering charged batteries from home at peak times when prices are high could be quite profitable. Mqurice
