The reason they are over unity is becaues they put out more than the
operator puts in in power. the rest of it is collected from the
environment. the input power is just used to divert environmental
energy. So even if the heat pump is only 50% efficient it can still
be over unity. Bearden has a good explanation for that, I watched his
DVD recently and he explained how the math is done in detail.
Solar and wind is all ovor eunity becaues the amount of power you put
in is much less than what you get out of it even thought a solar
panel is only abount 15% efficient. so one needs to differentiate
between effirioncy of a system and the COP as they are two different
things and you can have the COP be over unity but the efficiency be
way under unity. so when one uses the term overunity it needs to be
specified as "overunity what"?
