I’d like to make a PSU that can try out a whole bunch of charging strategies:
Instant = seconds to minutes.
Getting energy from light, heat, wireless, movement, RF, and anything else that seems interesting.
An anchor node running 24×7 with no maintenance required.
A wearable that can either scavenge power, or needs a few seconds recharging each day.
Can this be tried out with a single desktop prototype?

There's a lot of useful stuff for me to follow up on there. Thanks.
I was thinking of making a single PCB with jumpers for trying different options.
David Carkeek says:
Instant charging isn't possible yet with a battery. A supercap can charge very quickly but its energy density can't compare with a battery.
Solid State batteries? Maybe some news here: International Rechargeable Battery Expo "Battery Japan"
Energy from light seems to be the low-hanging fruit. I went to a session last year that yielded useful information. I need to dig it up.
Scavenging stray RF is worth looking into, but unlikely to yield much with a small antenna.
Body heat is promising.
Body heat power supplies
A single design isn't going to be suitable for all of the possibilities. A single PCB can have multiple designs; the PCB can be scored so the individual power supply layouts can be separated.
