60kWh - 720kAh - 3,000A charge rate and still 20 X 0000 cable .....

More coffee ...

  E = 0.5xCxV^2,

That said; Batteries, super caps or peanut butter, I don't care how the charge is stored...

I just want an electric that can do 100 miles on a charge, with swappable/stackable storage. That way you could get more batteries (or whatever) and only plug them in when you really do need to go 300 miles. My normal commute is 30miles round trip...why carry the extra weight?

I think they're too focused on "300+ miles". Give me 100 miles and I'm happy....make it stackable to satisfy the people that "have" to be able to drive 300 miles or more.

I wrote the following regarding such capacitor battery bank:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For those interested in the capacitor battery banks.

To store energy, one needs to determine the ultimate KWH and what the power source is and its limitations.

Taking as example what the patent says (if I remember right) 52 KWH hours of storage.

The bank has to accumulate around 3500 volts and one needs to remember the basic capacitor charging formula:

Current = 1 / 2 C *dV / dT and the energy available is 1 / 2 C *V^2

Also we need to make a correction for time

52 kwh = 52000 wh *3600 seconds = 187200000 watt seconds = 1 / 2 C * V^2
C= 187200000 * 2 / 3500^2 = 30.56 Farads.

Now we need to define the charging time, let's assume 5 minutes  = 300 seconds

Current = 1 / 2 * 30.56 * 3500 volts / 300 seconds = 89.1 amps

We need a 89.1 amps current source capable of having a range of at least 3500 volts to charge the capacitor from Zero (0) Volts to 3500 Volts.

One can see that the power source needs to be quite strong and expensive.

Home charging with 230 volts with 30 amps limitations, this 6.9 KW or 6.9 KWH limitations, so the charging time will be the 52 KWH(battery) / 6.9 KWH (house)=  7.536 hours

This time is minimum but we need additional time to take care of the equipment efficiencies and if we assume 80% efficient system then the hours become 7.536 / 0.8 = 9.42 hours

Here you have the generalized analysis of the charging time for such theoretical bank.

I am collecting information on using wind and water to make high-voltage AC so the alternator can be in the best collection site, and the house can be in the best home site, often far apart. Its my understanding that when the high voltage reaches the garage, it should be run through a step-down transformer to lower voltage, then rectified to a charging DC to the battery pack.

Franklin noted that even when there was no lightning, his cable conducted electricity from the air to the ground quite often. I plan on having a pond, even if its not a giant capacitor. But if a few small changes make it useable as a capacitor, the problem as I see it is, the voltage will be much higher than 120/240, so there would be no off-the-shelf management components available, plus, the voltage would not be a constant, but highly variable. I can buy a 110/12 volt transformer, but a "black box" that takes variable extra-high voltage and gives me a stable 12 volts, well, I don't even know what questions to ask! but theres gotta be a way.

I know that a cars tiny tail-light bulb can be hooked up directly to a 12-volt battery, but if I use cheap thin jumper cables with no resistance (but much thicker than the bulb filament), they will get hot enough to melt.

A Leyden jar is certainly inefficient for a given volume compared to a modern capacitor, but they are very easy and cheap to make. If one the size of a hot tub could kill a man, then it goes without saying that it would need a non-conductive berm and a significant fence and cover with warning signs. However, if its possible to occasionally harvest even a tiny fraction of the "free" electricity around us (even with a high self-discharge rate) I am very intrigued, even though I am "electrically challenged".
