Wind and photovoltaics energy require instant electricity sinks for when the wind blows and the sun comes out The big blunder was to not build those sinks in parallel with the installation of wind and solar farms. They make the wrong argument that storage is expensive. It is not if done right.
There are now swarms of electric cars and soon to be trucks. But they are designed badly.
They are designed with giant half ton batteries so that vehicles can get 500 km range. Then the vehicle is parked somewhere for an hour to get a part charge. Or half an hour at a supercharger to get a part charge. And that electricity has to be available then and will be priced at whatever the price is at that moment = if the sun isn't shining and the wind's not blowing it will be expensive. And the vehicle will also have to pay for the parking time at the recharger [about $10 an hour].
Hopeless. A vehicle and driver parked for an hour is expensive.
But Mq's amazing method solves all the problems such as cars being expensive and inefficient because of the stupid heavy batteries. Lugging an extra 500 kg up hill and with the extra rolling friction costs more energy. Waiting with a vehicle for an hour is $100 an hour down the drain. Maybe $40 an hour for an Uber driver or delivery vehicle. That's more expensive than the bloody electricity!!
Cars should be designed with 7 second pit stop 50 kg or maybe 100 kg swappable battery modules. Pull into a 7 Second Swap Stop station, car ejects and robot pulls out the discharged battery from one side. A robot pushes another one in from the other side. The car locks it into place, shuts the hatch and accelerates away, back up to highway speed in 3 seconds. Elapsed time = 10 seconds deceleration, 7 second battery swap, 5 second acceleration = total 30 seconds more or less.
The discharged batteries would be in a stack of 1000s which would be charged when the sun comes out or the wind blows, or when electricity prices are low, and electricity is actually available.
Hey presto, lots of problems solved. Cars cheaper to buy, less engineering needed, depreciation expense lower [it's the battery that wears out fast, not the other vehicle parts], better mileage, cheaper electricity, no waiting for a recharge. No cooling system needed for the battery I guess but maybe still needed. Wind and photovoltaic farms would have a place to put their electricity at all times.
But wait, there's more.
People with photovoltaics or wind at home could fill their car while parked at home, then instead of PAYING for a filled battery at the 7SSS station, they could drop off their full one and get an 80% discharged one and be PAID!! making their home photovoltaics economic. So there would be sinks everywhere.
Global Alarmists would love it as photovoltaics and wind would be cheaper than coal which requires somebody to dig the stuff up and carry it to a power station. CO2 emissions would decline.
