“Apple is purportedly talking to small development company Eneco, which has developed a chip that converts heat into electricity. If it works, it could have a big impact on how IT equipment, and in particular laptops and other mobile devices, are designed and powered. However, there are still several technological issues to be resolved,” Dennis Sellers reports for Macsimum News.
Sellers reports, “According to articles at Green Business News and Macworld UK, Dr Lew Brown, president and CEO of Eneco, told investors that its new chip technology ‘will revolutionize the way we generate electricity.'”
Sellers reports, “Eneco is a development stage company that claims to have invented and patented a ‘solid state energy conversion/generation chip’ that will convert heat directly into electricity or alternatively refrigerate down to -200 degrees celsius when electricity is applied.”

Holy Shit!
Does this mean I can charge my next laptop in an oven?
I dream of wireless AC and DC current to eliminate all those terrible power cords. Not holding my breath. The guy who invents that will be able to buy the state of Hawaii.
Now that sounds really . . . cool. Let’s hope it’s going to see the light of day.
GP is hoping for “wireless current”? Isn’t that called “lightning”??
Does NOT sound like a good idea!
LOL
A purpetual laptop power source. The laptop uses energy which generates heat. The magic chip converts the heat into electricity to power the laptop. Which generates heat.
Damn — shoulda kept those G5 space heater chips for use in your laptop!
re “cooling mode”: what happened to the second law of thermodynamics? The heat within a closed system can never deminish (it has to output heat in order to cool).
Doesn’t this kinda sound like the Peltier effect?
I don’t get what’s the big deal – you can build one of these things in your garage. It uses a Peltier device, which has been known about for ages. People use these things to cool their gaming rigs all the time.

as ApplePi put it..
HOLY SHIT!!!
Also, w/ the alternate cooling down, sounds like the possibility of compact, portable, sub-zero multi-100 GHz Processors 😀 😀
HOLY SHIT!!!
> I dream of wireless AC and DC current to eliminate all those terrible power cords. Not holding my breath. The guy who invents that will be able to buy the state of Hawaii.
I don’t think so. There have apparently been MANY such technologies invented over the years, only to be bought up and shelved by oil companies, hidden from the public for reasons of “national security”, or whatever. The real trick doesn’t seem to be inventing this stuff, but getting it into the pulic’s hands. Long live capitalism!
MDN word: This is just ANOTHER amazing, planet-saving technology that’ll be lucky to see the light of day while oil companies keep getting richer.
That is not econo invention, that is called “Termoelectric Chip” you can find it on ebay or JAMECO, it is a simple ceramic chip that “Pumps” heat from one way to athoner depending on the polarity, for that reason, is colds the other side, so you use it as a heater or as a cooler, but if you apply heat, you can produce electricity. I put one of those in may old PowerMac dual G4 on the heat sink in order to cool it.

MIT is working on this to power home electronics/appliances

Name some? Electricity already exist. why would an oil company want to rid of someone that just takes the cords away?
“I dream of wireless AC and DC current to eliminate all those terrible power cords. Not holding my breath. The guy who invents that will be able to buy the state of Hawaii.”
I think it was invented by Nikola Tesla. Tha capability to beam power from one source to another. Just don’t stand in the stream.
I dont think this is what you are referring to Des Gusting. The original poster was merely commenting on a way to get rid of power cords, not to generate cold fusion, which is what I think you may referring to.
I can see it happening. Also, I think Steorn is on to something.

Concur with other posters on this thread – thermoelectric and thermionic power generation has been around for a while. NASA has used this power conversion technology for space missions using a radioactive material as the thermal power source (RTG’s). You can buy thermoelectric coolers at the sporting goods store that heat/cool using solid state technology. The issue is that the conversion efficiency is very low (few percent). Unless an efficiency breakthrough has been made, that is state of the art to the best of my knowledge.
It is not clear to me how Apple could effectively employ this technology on mobile electronics. The power generation aspect seems next to useless to me unless you can locate a thermal source (it would be simpler to find an electrical outlet). As far as cooling goes, it takes a lot of electrical power to get a little cooling due to the efficiency issue. I can’t see this working in a power-constrained mobile device. Besides, the extra power creates more thermal energy which must also be dissipated.
I just don’t see any technical merit in this approach.
macromancer:
you stole my thunder. Tesla is the inventor of transmitting energy wirelessly. Even though Marconi was originally credited with the invention of the radio, Tesla held the patent on which that technology is based. So the credit of the radio now belongs to Tesla. There is a you tube story on Tesla that runs about an hour, if you have the time.
Who cares if the laws of thermodynamics are violated. The end of laptop batteries has arrived. Sit on a pack of these chips and generate enough electricity to drive it.
To Lord Byron and macromancer: Yeah, sorry, got my wires slightly crossed there and commented on the article rather than Georgy’s post.
But for some interesting reading check out a book called “Suppressed Inventions” and mags like Nexus. There’s probably a lot of crap in there to make self-righteous sceptics happy, but there’s also a lot of what appears to be truth.
Daniel, in this scenario it’s not a closed system ( you add energy in the form of electricity and you remove energy in the same form thanks to the chip) so the law does not apply. Simple logic.
Concerning technologies being squelched by oil companies, etc., I heard a story this summer about a local inventor who had designed and installed a carburetor on his Chevy V-8 that got 50 MPG. The auto companies tried to buy the rights to it, but he refused knowing full well that they would suprress the device. Not long after his refusals he disappeared and no one knows to this day what happened to him.
Could be a real tall tale, who knows? But I am always amused by stories like this.
Now consider how slow Detroit is to introduce high mileage hybrid cars — there’s a case for squelching technology. Or GM’s destruction of the EV1 electric cars — that’s real suppression!
I tend to agree that the conversion will be nowhere near 100% and those who are proclaiming the end of batteries for a laptop are premature.
That said, this could easily be fed back into the batteries. Depending on how efficient it is, it might add an extra half-hour or more of battery life. Or you could use smaller batteries for the same amount of life. So figure you could have a MacBook Pro weighing in at under 5 pounds–not too shabby.
Neat idea. We’ll see if anything ever comes of it.
Heat = electrical power?
Really?
Can you imagine the implications during an Arizona summer? Set your computer outside and recharge your battery in 30 seconds!
MDN Magic Word “however” as in however you’ll get heat stroke just as fast!
Brilliant!
Ummm, you all are getting this entirely wrong: this is heat _recovery_ technology. In other words, you slap this chip on your processor and/or GPU, and it’s wired into the power supply. As the CPU heats up, electricity is generated, and is pumped back into the power supply and then to the battery for charging.
This isn’t some magic “we can get rid of batteries” thing. It’s a way to recover lost heat (due to the 2nd law of thermodynamics) and turn some of that into useful electricity, therefore increasing the time you can use a laptop away from a power supply.
Now, as some have noted, the real question here is how efficient is this little beastie? If it’s only a few percent, then it’s unlikely to make much difference to your battery life. If it’s up around 40 or 50%, then we could see significant bumps in “on the road” computing. Here’s hoping it’s the latter!
Now if they could only recapture the methane Peterson spews, or the compost of the .dmg dorkuses, Macs could almost be a perpetual motion machines.
re: “what happened to the second law of thermodynamics? The heat within a closed system can never deminish (it has to output heat in order to cool).”
Daniel, how is that a closed system if its being supplied with energy/current fron an EXTERNAL power source! However this appears to be a heat pump mode, albeit a VERY efficient one…
Just my two pence’s worth

Isn’t that what killed Tesla? That’s dangerous shit.

Apple busted by the physics police for breaking the Second Law. News at eleven.
If this is for real, the best utilization for computers would be for the chip makers to design their chips to run cold using the cooling mode of this technology. The key is that the efficiency of this thermionic emission technology, like the old vacuum tubes, must be far more efficient than available Peltier coolers — which are very inefficient.
This would result in chips that use far less power than chips running at much higher temperatures. So the power efficiency of the accelerated chips would have to more than compensate for the power to cool them.
To Daniel and others
The Second Law of Thermodynamics actually states that the *entropy* of a closed system can only remain the same or increase. There is nothing in it that says that it must involve heat.
Consider a cup of milk and a bucket of water, both at the same temperature. If you introduce the milk into the water, you will find that the milk begins by being concentrated around the place in which you poured it into the water. Over time, however, it spreads to finally be spread evenly throughout the water. The entropy of this closed system has progressed to its maximum level without any heat being exchanged whatsoever.
Pouring hot water into cold is an analogous example, but as you can see the concept of entropy is far broader than heat alone.
Converting heat into electricity is not new. In fact photovoltaic cells have been around for a while, they convert light (high frequency heat) into electricity by pushing electrons into higher energy states around their atoms so that they can be skimmed off with an electrical field. In this whole interaction, you can expect entropy overall to increase. Some of the heat is lost in the apparatus, some of the electrons fail to be captured in the current, and the electrons will generate heat in any wire they travel in, resulting in their being captured by the nearest atom, and the heat radiating into your desk or whatever.
King Mel says: “It is not clear to me how Apple could effectively employ this technology on mobile electronics. The power generation aspect seems next to useless to me unless you can locate a thermal source (it would be simpler to find an electrical outlet).”
Unless of course that thermal source gave off a particularly large amount of heat … Perhaps Apple knows something about the consequences of scaling up Intel’s mobile chips that they’d rather not be a showstopper for them in the future?
Steve Jobs CNet inteview circa 2009: ‘Well, yes, the thermal dynamics of Intel’s new Core2Duo2Squared ARE roughly 80 times worse than the competition … and yes, IBM’s new experimental PowerCell3 has actually demonstrated the ability to preserve raw ham on a Georgia roadside in the summer … But look – we can generate 50 Gigawatts of power from Intel’s CPU! We call our new computer: The iPerpetualMotionMachine. What’s that? NO I’m not exaggerating the performance! Of course not. Why would you even ask me, of all people, such a preposterous question?!’

Ah nice to see people know about this technology. Don’t forget gel ponds, used by the asians to take advantage of temperature differences at different depths of water.
Love Tesla.
Can you say infinite power? Imagine having heat generated by your laptop, recycled and used to recharge your laptop’s battery. Interesting concept, eh?
Holy icicle Batman!
From the story: “The chip is based on the principles of thermionic energy conversion whereby the energy of a hot metal over comes the electrostatic forces holding electrons to its surface. These free electrons then pass across a vacuum to a cold metal and in the process create an electronic charge that can be harnessed.”
Holy Atwater-Kent! Vacuum tubes will change the world!
nukeman: re thermodynamics … the point is that heat must be produced somewhere in order to cool elsewhere (check your refrigerator). The net heat produced (heat – “cooling”) is always positive. Indeed the Peltier effect produces heat at one junction while cooling another. So what we have is a (hopefully efficient) method of heat transfer.
McGherkinstein Jones: Indeed the second law speaks to the change of entropy. And the change in entopy is defined as the change in heat of a system divided by its temperature.
I’m hoping this is a way to quietly cool (by transferring heat without fans). I greatly prefer quiet computers as does Jobs. When he introduced the first Macintosh he said computers should be as quiet as toasters.
