I just hope nothing happens to this guy. It could place major players products in jeopardy. There's conspiracy theories of inventors getting done off when they invent anything that would jeopardize the oil companies, i.e. oil.

no question.....from ooga-booga times, to the creation of religion, to our current form of 'heirarchy' that drives the economic engines, it's one of the few remaining cultural constants that have stood the test of time....
however, in this case, the paper is published.....no differently than arresting the drug dealer, there's others that will replace and continue research if so.....hell, even Tesla took out the 'almighty' overrated Edison.....
#1/0 will always reign supreme until we die off as a species.....time is the only variable
Graphene has been one of those exciting substances that seems to have incredible uses. Its used in supercapacitors and I believe battery technologies. They are probably only scratching the surface of what it can do.

yessir.....IMO, nanotech and bio-engineering will become the next version of the industrial revolution.....how the cause/effect in growth relative to actual numbers of the bipedal wanderers is what I question.....
to say the least, we're currently only beginning to witness the impact today.......imagine what she'll be like a century from now.....
whoever wins that race will control how currency interacts....who lives and who dies and when.....
I haven't listened to the youtube yet, but I wonder if the professor is comfortable with the title "A Potential Source of Clean, Limitless Energy"?
What this appears to be talking about is that nano-devices or implants can be powered by the person in which they are implanted. Graphene in this case converts ambient heat (i.e. body temperature) into electricity to power a sensor or other monitor.
That doesn't mean that you'll shove a plug up your arse and run a Tesla...
another discovery.....scientists created a new material from two layers of graphene called diamene that has the flexibility of tin foil at room temperature until pressure is applied giving it the stiffness/hardness equal to or greater than that of diamond.....

the more we discover how to control elements the more we allow our species to adapt/evolve/survive.....
I see the ones that are living a century or two down the road will view today in the same vein as we look at the wild west now.....
what I find fascinating is how what we know today has been achieved exponentially in relative terms....
getting to the point of defining the periodic table was a monster....it's essentially snowballed from that point.....
they're both really good reads for those that are interested in science.....

Not so sure it's even relative - I think it actually is an explosion of knowledge on an exponential rate. From what I can see, there doesn't seem to be a plateau in our near future. I expect at some point the acquisition of knowledge will slow down, but that's just one opinion and I wouldn't expect the slowdown to occur for at least another 100 years.
Quote:Thermoelectric devices, which can generate power when one side of the device is a different temperature from the other, have been the subject of much research in recent years. Now, a team at MIT has come up with a novel way to convert temperature fluctuations into electrical power. Instead of requiring two different temperature inputs at the same time, the new system takes advantage of the swings in ambient temperature that occur during the day-night cycle.
The new system, called a thermal resonator, could enable continuous, years-long operation of remote sensing systems, for example, without requiring other power sources or batteries, the researchers say.
The findings are being reported in the journal Nature Communications, in a paper by graduate student Anton Cottrill, Carbon P. Dubbs Professor of Chemical Engineering Michael Strano, and seven others in MIT’s Department of Chemical Engineering.
“We basically invented this concept out of whole cloth,” Strano says. “We’ve built the first thermal resonator. It’s something that can sit on a desk and generate energy out of what seems like nothing. We are surrounded by temperature fluctuations of all different frequencies all of the time. These are an untapped source of energy.”
While the power levels generated by the new system so far are modest, the advantage of the thermal resonator is that it does not need direct sunlight; it generates energy from ambient temperature changes, even in the shade. That means it is unaffected by short-term changes in cloud cover, wind conditions, or other environmental conditions, and can be located anywhere that’s convenient — even underneath a solar panel, in perpetual shadow, where it could even allow the solar panel to be more efficient by drawing away waste heat, the researchers say.
The thermal resonator was shown to outperform an identically sized, commercial pyroelectric material — an established method for converting temperature fluctuations to electricity — by factor of more than three in terms of power per area, according to Cottrill.
The researchers realized that to produce power from temperature cycles, they needed a material that is optimized for a little-recognized characteristic called thermal effusivity — a property that describes how readily the material can draw heat from its surroundings or release it. Thermal effusivity combines the properties of thermal conduction (how rapidly heat can propagate through a material) and thermal capacity (how much heat can be stored in a given volume of material). In most materials, if one of these properties is high, the other tends to be low. Ceramics, for example, have high thermal capacity but low conduction.
To get around this, the team created a carefully tailored combination of materials. The basic structure is a metal foam, made of copper or nickel, which is then coated with a layer of graphene to provide even greater thermal conductivity. Then, the foam is infused with a kind of wax called octadecane, a phase-change material, which changes between solid and liquid within a particular range of temperatures chosen for a given application.
I really doubt this kind of device would give you a non-stop current like the PI here says.
What I do find interesting here is that he apparently is converting thermal energy in the air to current, which would seem to me to be a way to circumvent the second law of thermodynamics (you have to have some kind of energy input to take heat from air).

to dumb it down in comparison while going back in time.....think about how they figured out that freon could change state and create what is now the critical component we now ubiquitously call "air conditioning"....that was less than 100 yrs. ago folks
if that doesn't happen, none of what we know as reality exists today in it's current state (pardon the pun)
I have it from a very good source that that's what ETs use for their alien spacecraft. That's all I can tell you otherwise they might beam me up and charge me with treason.
