Experiments in DIY supercapacitors
Just back from Brussels where I worked for 5 days on DIY supercapacitors with my inspiring friend Michka Melo. We worked on the premises of the equally inspiring organisation Foam, trying to build supercapacitors from upcycled computer batteries and other methods including chemically altered cuttlefish bone, in a true citizen science spirit!
[Supercapacitors are electrical storage devices that become a viable alternative to conventional batteries, making up for lower capacity with a very fast charging time and much longer life.]
Michka compiled a detailed account of our experiments. Thanks to Robert Murray Smith for valuable info on DIY supercapacitors.
