Potato power: the spuds that could light the world
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.
Their cost analyses suggested that a single boiled potato battery with zinc and copper electrodes generates portable energy at an estimated $9 per kilowatt hour, which is 50-fold cheaper than a typical 1.5 volt AA alkaline cell or D cell battery, which can cost $49–84 per kilowatt hour. It’s also an estimated six times cheaper than standard kerosene lamps used in the developing world.
In 2010, the world produced a staggering 324,181,889 tonnes of potatoes. They are the world’s number one non-grain crop, in 130 countries, and a hefty source of starch for billions around the world. They are cheap, store easily, and last for a long time.
In a country like Kenya, the potato is the second most important food for families after maize. Smallholder farmers produced around 10 million tonnes of potatoes this year, yet around 10-20% were lost in post-harvest waste due to lack of access to markets, poor storage conditions, and other issues, according to Elmar Schulte–Geldermann, potato science leader for sub–Saharan Africa at the International Potato Center in Nairobi, Kenya. The potatoes that don’t make it to the market could easily be turned into batteries.
