Generate electricity from coins

With coins, wires and salt water, we can create electricity in a fairly simple way.

Entrepreneurs take advantage of the fluctuations in the value of money in the market to make a profit, while Jonathan Keat, a painter in the US, comes up with the idea of ​​generating electricity from metal coins. Chinese and American coins were chosen by Keat during the study, Livescience reported.

American coins.

Chinese coins are cast in aluminum, and US coins are cast in bronze. Corrosion on both coins occurs when they are immersed in an ionic-rich substance like seawater. When immersed in seawater, aluminum is corroded faster than copper so the positive ions from aluminum will move in the water to the side of the copper. Electrons also move in the opposite direction (from copper to aluminum) through metal wires attached to two coins. We all know how electrons move.

The higher the number of coins in a solution, the greater the amount of electricity generated. The US government makes about 4 to 5 billion coins every year. Like Chinese coins, the coins of Thailand, Japan and Peru are also made of aluminum. With such abundant production materials, Keat thinks he only needs a small piece of land and the amount of seawater is large enough to create a small power plant.

'If I want to produce 6 million KW of electricity, I need about 600 million pairs of aluminum - copper coins, a small number compared to the amount of coins that countries cast every year,' Keat said.

Keat insists that his method of producing electricity is not only cheap, reliable but easy to apply because even people who know a little about physics can do it.

'Thanks to this method, the value of money is represented by a specific number. We can measure it with Volt (voltage difference) and Amp (current intensity) , ' he said.
