BBC – Future – Potato power: the spuds that could light the world

With a simple trick, the humble spud can be made into a battery, so could potato powered homes catch on?

Mashed, boiled, baked or fried? You probably have a preference for your potatoes. Haim Rabinowitch, however, likes his spuds “hacked”.

For the past few years, researcher Rabinowitch and colleagues have been pushing the idea of “potato power” to deliver energy to people cut off from electricity grids. Hook up a spud to a couple of cheap metal plates, wires and LED bulbs, they argue, and it could provide lighting to remote towns and villages around the world.

They’ve also discovered a simple but ingenious trick to make potatoes particularly good at producing energy. A single potato can power enough LED lamps for a room for 40 days,” claims Rabinowitch, who is based at the Hebrew University of Jerusalem.

The idea may seem absurd, yet it is rooted in sound science. Still, Rabinowitch and his team have discovered that actually launching potato power in the real world is much more complex than it first appears.

While Rabinowitch and team have found a way to make potatoes produce more power than usual, the basic principles are taught in high school science classes, to demonstrate how batteries work.

To make a battery from organic material, all you need is two metals – an anode, which is the negative electrode, such as zinc, and a cathode, the positively charged electrode, such as copper. The acid inside the potato forms a chemical reaction with the zinc and copper, and when the electrons flow from one material to another, energy is released.

This was discovered by Luigi Galvani in 1780 when he connected two metals to the legs of a frog, causing its muscles to twitch. But you can put many materials between these two electrodes to get the same effect. Alexander Volta, around the time of Galvani, used saltwater-soaked paper. Others have made “earth batteries” using two metal plates and a pile of dirt, or a bucket of water.

Permaculture Greening the Desert – YouTube

This video shows how Geoff Lawton went to the Jordanian desert in 2001 and turned a ten acre bit of desert and turned it into a orchard.if this can be done in the Jordanian desert imagine what can be achieved not just here in the United Kingdom but everywhere.

We are trying to set up similar projects here in Devon but without the support for Permaculture companies and councils are not interested please show support by visiting
