Energy Harvesting for Electronics
I recently highlighted a novel audio amp that can run off batteries for a long, long time. And I’ve been collecting some other low power stuff that I’ll share here. But what really makes it complete is the concept of Energy Harvesting!
Hyper Efficient Audio – 100 W from a single battery!
It’s amazing what application specific integrated circuits can do now. I never stop being surprised at what I keep seeing coming out of the pipeline. Audium Semiconductor recently gave me one such surprise with the hyper efficient AS1001 amplifier that can deliver 100 watts peak power, from a 1.5 volt (read single battery) power supply.
Driving the Nissan Leaf
The Nissan Leaf is an all electric car for the masses. On paper, the car seems to be a much more realistic proposition than cars like the Tesla or the Fisker. It’s a small 5 seat car, with a range of 100 miles and a target price somewhere a bit above $25k. For many, this [...]
Battery fill up via pump?
Turns out the crafty Germans are at it again! As reported in the Fraunhofer Research News recently, a group there is working with something called a redox flow battery. Basically it uses a liquid instead of a solid to store the charge. This isn’t new, but the team has brought the energy density up to that of [...]
