test,wanted to have a link back to this thread.I want to make supercapacitors now.

Question:   

Are you doing this with Charcoal Briquettes or actual Coal???

[Paul-R]

Having built the capacitor, when using it as a replacement battery,  how do we regulate the output voltage to give a fairly constant voltage as the cap discharges?

(Obviously, a voltage regulator would do this but will waste most of the power).

Votlage regulators don't all waste most of the source power.  Many switching supplies are well above 90% efficient, and some specialty designs are over 99% efficient.

Mark,
What about the Robert Murray Smith self charging graphene super cap. If it truly recharges itself then it has to be at a minimum 100% efficient...no?
