|> How could it consume 1800W of electricity and produce 2200W of power? It

|> Another example: Milwaukee 6391 has a 15 Amp motor and claim the saw has 3
|> 1/4 horsepower.
|> Since 1 horsepower = 746 W, 3.25 HP = 2424.5 Watt. It is even more

|> Why hasn't these more than 100% efficient machines made the headlines?
