> Bitcoin has been accused of wasting energy in the past because of the computing power it takes to mine coins, but Gogerty says that SolarCoin is 50 times more energy-efficient because its algorithm allows the total number of coins to be mined faster... That's not how crypocurrency mining works. Mining more coins in a shorter period of time does not make it more efficient. It just means the coins are worth less money.
