The whole free energy / Zero point energy and being able to harness it if it is real? I understand that some law is violated in theory and so it is said to be impossible. Also confusion over closed system and a true open system that receives it energy from it's surroundings (whatever that maybe) I've noticed there are a bunch of crackpots on youtube so it is hard to discern the truth about the subject.

Roughly speaking, when you want to do work, it's not the energy itself that is relevant, but the energy difference between two states or systems.
Zero-point energy can be thought of as a consequence of Heisenberg's uncertainty principle; since the ground state of a system cannot have a precisely determined position, particles must still be moving. Currently there does not appear to be a serious or credible proposal for extracting zero-point energy in a useful way.

And also, has he already disconnected his house from the electricity supply and currently running off free energy.
This is similar to the way one tests any claims made by creationists. You check whether they have produced a youtube video, or if they have successfully published an article in a peer reviewed science journal.

My easy test would be merely to observe and note whether this is the case. Obviously, the 'crackpot' fails my test so would be judged to be a real crackpot.
But, although the chances of it being possible to extract zero point energy out of free space must surely be minute, the rewards for finding a way (I guess it would have to be an extremely clever way to get around the laws of physics! ) would be so fantastically great, it may be still worth doing research into it just in case there is a way for that would mean free unlimited energy. I would call such research an example of what I would call "long shot research" -research with extremely low chances of successes but considered worth doing anyway because of the massive potential rewards if successful. Another possible long shot research would be into warp drive or other faster-than-light means of travel.

Basically atoms have a resonate energy and will always have energy even at their most basic energy state or lowest state. Does this tie in with string theory? It must.

Of course it is possible that string theory may be a more general theory than our current quantum theory.
Edit: it also has nothing to do with dark energy.

It sounds like Zero point energy is real but it's not like some average Joe is going to make a device in his garage on the weekend that's going to run off of it. LOL It sounds like theoretically it could explain the dark energy pushing the universes expansion.
