No, it doesn't. It sounds like a business and they are developing technologies for commercial applications, so they won't be free. In the window coating example you'd be getting more or less energy from the sun depending on how you control the coating, but they expect to sell those coatings I'm sure...they won't be free.

I think he's doing himself a disservice by calling it that since:
In pseudoscience:
Free energy device
a hypothetical perpetual motion device that creates energy, thereby contradicting the laws of thermodynamics
a device of which a controversial claim is made that it taps an unconventional energy source not regarded as viable by the scientific community at large
In popular culture:
Free energy suppression, a conspiracy theory that advanced energy technologies are being suppressed by governments and/or special interest groups

Yes, this was published on Jul 9, 2012 from a TED Talk in Scotland.
Nice find but since I have heard nothing more about it, I had forgotten it.

We call windmills free energy but we have to buy the windmills obviously!!
I think we all know what we mean by FREE energy. It means we're not tied to oil barrens. It means we don't need to provide a fuel. It means were not continually stripping something from the earth. Its very often pollution free too!
By your reckoning free means it should magically materialize in front of us ready packed into a nice battery. We all know that's silly
Compared to oil this IS free because we only need to buy it once.edit on 31-7-2013 by VoidHawk because: (no reason given)
he's selling, blah, blah, meh
No, we don't call windmills free energy. This is my point. Look at all the free energy threads on ATS and the free energy videos on youtube. They aren't about windmills.

I assure you most people are not thinking of something that's more expensive than what they are currently paying, like wind power is in the US, when they talk about free energy.
Wind turbines reached grid parity (the point at which the cost of wind power matches traditional sources) in some areas of Europe in the mid-2000s, and in the US around the same time. Falling prices continue to drive the levelized cost down and it has been suggested that it has reached general grid parity in Europe in 2010, and will reach the same point in the US around 2016 due to an expected reduction in capital costs of about 12%.[111] Nevertheless, a significant amount of the wind power resource in North America remains above grid parity due to the long transmission distances involved.

OR maybe the ideas simply didn't work as expected or, if they did actually get results, the economics of implementing it didn't add up to a figure that was competitive with existing energy sources. To be at all competitive in today's energy market you'd have to be able to produce each megawatt-hour for less than about $40 (or 4c/kWh) and that's over the life of the device(s) including all maintenance and operational costs
like labour and compliance testing for connection to the grid and don't leave out the transmission lines & protection systems in the calcs.
