Question

A company claims its washing machine produces 4000 joules of work output for every 3000 joules of work input. What would make you skeptical about this claim?
​

Answer 1

Things that make me skeptical: No evidence is provided, the company also claims that its washing machine produces 4000 joules of output for ever 3000 joules of input, and there is no possible way of creating a joule output larger than the input, unless your using coils to increase electricity, but that's not what washing machines have inside of their machinery. Washing machines don't have mini Tesla coils inside their machinery!

I hope this helps!
