Batteryless Solar Electronics
Can we make electronics more sustainable, with lower impact to the ecology? One way is to design them differently, more like batteryless solar calculators or Citizen eco-drive watches, which never wear out. In this space I invite a sharing of DIY projects which apply this energy harvesting strategy toward consumer electronics, a traditionally “fast-cycling” industry, and an invitation to remediate the 15 billion battery discards occurring worldwide, each year.

Hi Brian, thanks! This is such a crucial topic. I’ve been reading work by the Romanian economist Nicholas Georgescu-Roegen, who tried to bring entropy and energy dissipation into focus in economics. He’s been an important inspiration for the degrowth movement. He challenges the idea of a steady-state system as a kind of fiction. There is always some kind of dissipation, entropy, loss, and so for a system to be truly sustainable, it must be open to an outside flow in some way. This is what the sun is for us generally, and so solar influx is one kind of resource to design with. But I also wonder about other forms of available energy, like the energy generated by kinetic movement. There are watches, for example, that are powered by the movement of those who wear them. I wonder if one could begin to imagine electronics also powered by incidental kinetic movement, or other forms of energy already out there in the world.

You would probably like the raindrop powered electronics project.

Not solar, not batteryless, yet relevant:

I’ve seen some of these that do not have batteries — just a turbine in the water generating electricity directly to USB device.

Portable turbine provides a "stream" of power for charging devices
Portable solar chargers are perhaps the most popular means of keeping devices powered in the wilderness and, as we've seen, portable wind turbines are an option too. To cover all bases though, you may soon also be able to take … Continue reading

Hello, Ecological Design Collective:
Recently at the Green Tech Hackathon in Amsterdam I had a chance to develop how to type instructions for batteryless solar electronics — here’s a link!
Enjoy and shoot me any questions.
