Make a magnesium copper battery that lasts for a year. It appears each cell provides about 1.5vdc and 20ma, enough to power an LED light for a year or more. Using a voltage booster with one cell will increase the volts but decrease the amps meaning you will not be able to power an LED light. So make 2 cells and put them in series for 3vdc 20ma output.
