Running On A Tank Of Sunshine

This is a replication of an idea by Grandad where he ran a solar waver device on a directly connected supercapacitor. What was unusual about what he did was that the small super capacitor stored the excess solar energy during the day and then ran the device at night —-on the little tank of stored sunshine. How long it ran wasn’t really important but rather that the simple idea worked at all.
Here is Granddad’s video showing his experiment with this idea: https://www.youtube.com/watch?v=cDCQJMbzLEE&t=0s
