There’s actually a decent amount of research into exactly this sort of thing, called, appropriately, “energy harvesting”. Depending on the application, it can be fairly effective. I know that vibration energy harvesting has been successfully in machinery monitoring applications, for example. I haven’t looked much into stray EM harvesting, but I’m sure it is possible…most likely to supplement a primary energy source rather than as the main source itself. But, yeah, for sure it’s an interesting topic with a fairly good amount of study into it…I think the University of Michigan had a few good research programs related to harvesting for ultra low power applications. You night check out some of what they’ve done

Nice! Enjoy the show!

What concert?

Share a Bandcamp/Soundcloud link if you’ve got one!

Where (generally) were you hiking? I live near the Appalachian Trail & I love to get out for a good hike every now and then.

It remains on my computer since 1998 so I don’t need to learn any new tools.

Mostly kidding…but to be honest, I have just never had any need to try any other tool…it works perfectly for what I need to do (multi-tracking, sequencing, mixing). There’s almost nothing I would want it to do that it doesn’t…so I just stick with it.

Cool Edit Pro. Such a great audio editing tool.
