If I used a heatpump to draw heat out of the sea, drive a steam turbine that'd drive the compressor and pumping system, and generate surplus energy, is that an over unity device?

No, because the energy is coming from the sun.

What energy is coming from the sun?
It looks to me like it is an over unity device.

Drawing heat out of the sea? It's definitely coming from the sun.

How about hooking a tube from my ass to a natural gas burner, use that to drive a generator? It comes from where the sun don't shine. When I eat beans I could run the whole house.

Drawing it out of the earth is better. Geothermal.
Its not over-unity though because the energy is stored in the planet and will one day run out same as the sun.

No...it's actually an energy sink you've got there...not an energy source.
Heat pumps require energy to work and, in the case of every heat pump we have, can require much more energy than you can ever get from the heat you collect.
Reason being, you are taking something that is at very high entropy (a sea filled with heat) and trying to put it into a low entropy state (collecting all that heat and putting it in one place).
--------------------
You're here because you know something.
What you know you can't explain,
But you feel it;
You've felt it your entire life.
That there's something wrong with the world.
You don't know what it is, but it's there....
Like a splinter in your mind...
Driving you mad.

Oh yes, I see it now. I assumed he was talking about extracting energy directly from the heat of the ocean. Which would work in some places, at some times of the year, as it would require the sea to be warmer than the air. In that case the energy is coming from the sun.

I read it like he wanted to power the heat pumps with the energy they provide; which would be over unity.

I don't get it. A heat pump doesn't make energy right? Are you talking about the generator/heatpump combo or something?
Why is this over unity? Take heat from the ocean and power the generator with it, use the generator to power the heat pump and yield the rest as usable energy. ?
Is this some technical point about the definition of a heat pump I may be missing? While I understand the common examples, isn't it just anything that transports heat by an active process?
Are you just saying its unlikely this could ever work due to the temperature of the ocean and the inefficiencies of the process? I could see that. But like zouden said, if the sun is heating tidal pools or something why couldn't you get energy from the sun? Or just a hot part of the ocean?

Yes, I think the proposal was to use active pumping to collect heat in one spot, then use a heat engine to generate electricity from that, and use that electricity to drive the heat pump (and more). I couldn't think of a system less likely to work.
