No, that's a 75% increase. A 175% increase from 40%, using Method 2 () gives:

(40+(40*1.75))=110% efficiency

- so we are still in the realms of perpetual motion machines. If they really can do this, buy stock right now
No, thats wrong.

It is 175% MORE efficient than it already is, which means 1.75 more efficient... That makes it 70%.
