Scientists make electricity from tap water
Cool.
A team of Canadian researchers has found that an electrical current can be produced between the ends of a microscopic channel when a fluid flows through it.
...
A typical setup using a ceramic filter and tap water can produce 10 volts and the current depends on the size of the filter. Since large water pressures are not needed, natural flows of water can be harnessed. These could include tidal water flows, underground aquifers, dammed water, drinking water currently being filtered by utilities companies to improve its clarity, and rain falling from roofs.
