Look at caswell.com for electroless nickel plating kits.
If the copper is just a conductor, I don't care about tarnish on the
non-mating surfaces.
Where the bars meet, or the wires attach, polish the copper and use an
ant-ox compound.
I like brass bolts and nuts with flat brass washers.

5,000j is 5000 watt/seconds or 6.7 HP for 1 second
100 amp-hour battery at 360 volts is 36KW-Hr or 129,000,000 watt-seconds or
joules.
To store 36KWhr at 360 volts, you would need 2,000F of capacitor rated at
>360volts. When 50% discharged, the voltage would be 254volts.

the result is air at over 90% oxygen. The pressure is dropped and the

Most of these can run off DC either from DC input terminals or Just run the

The biggest cost for either system is posible litigation when someone get

Most of the USA requires all consumer products be UL or similarly listed.
Some cities are stricter than others. On top of that it is a liability
issue for both the manufacturer and the user.
If JuiceBox gets a UL listing it will only apply to new units. Old one will
still be noncompliant.
