Using nanotechnology to convert waste heat into electricity | Charles Stafford | TEDxTucsonSalon

Wow this man explained this ridiculously complex interaction with high school level knowledge. Awesome.

This was a pretty cool video. I’ve spent all day today trying to think of ways to convert thermal energy into electricity, in hopes to 1) produce energy, and 2) theoretically reduce the heating effect from CO2. I can’t fully grasp my head around why there has to be a pressure differential to do it though. In this case that pressure is created from a hot and cold barrier, similarly an engine turning over is created by a literal pressure differential produced from gas combustion on one side and atmospheric pressure on the other. This demon he was talking about was similar to a thought I had where you may be able to selectively grab the energy and throw away the particles with little energy. Although the demon idea is far more developed. If this type of technology could be advanced there’s so much potential.

Solar Furnaces, quite often Sun heat into a tube, need this to turn the heat they gather into electric. Solar Furnaces have be indicated to be more efficient than Solar Cells but it is much more difficult to turn any heat into electric

Great science and insight into needed solutions for renewable energy.

[@kristopherleslie8343]

Hoping they have improved efficiency to beyond 10%

[@anthonydunn729]

how does that produce electricity though?

Anthony Dunn when u create a tempaturr difference u increase the voltage of a conductor look up the seeback effect

I'm writing a sci-fi story where there is tech that can harvest the heat in air and convert it to hydrogen and cool the air at the same time. Anyone who understands the science of heat who wants to give feedback on my imaginings?

[@emberjaxx585]

How does the heat get converted to hydrogen, and how does it cook the air? Lol. A guess there’s a part of science that might make sense that you can manipulate into pseudoscience. Theoretically Energy can be converted into mass I.e. Albert Einsteins equation E=mc^2. All heat is, is positive thermal energy. So you might be able to write it as you’re putting heat into the system which is resulting in the production of hydrogen mass. You may also be able to conclude that since hydrogen is the smallest molecule on the periodic table that it takes less energy to produce then that of another element. Since the heat is converted to mass the result is less thermal energy in the air resulting in a cooling effect. It will probably be hard to explain the production of mass from heat energy though. Good luck though, writing these kinds of stories are fun, and entertaining.

Don't take PHYS 141 with this guy
