Generating Energy from Heat with a Chip


We've talked about passive energy generation before, but those devices pulled minuscule amounts of power from heat or vibration. Eneco, a company I've never heard of before, has created a solid-state (no moving parts) device that converts heat to electricity with 30% efficiency. The device consists (very basically) of two pieces of metal sandwiching some kind of mystery semiconductor. The trick is that one piece of metal is specially designed to lose electrons when heated, and the other is designed to accept them at a lower temperature. If electricity is applied to the chip, the bottom piece of metal becomes extremely cold, if heat is applied to the bottom piece of metal, electricity comes out.
The first applications are obvious ones. Off-grid electricity for pipeline monitoring (pipelines are usually quite hot to i use it cialis canadian keep the oil flowing well.) But the viagra canada cheap possibilities for the automotive and cialis no doctor consumer electronics industries excite me much more. We all know about waste heat from our laptops. All that wasted heat means a hot lap and less battery time. But the Eneco device promises to harness a lot of that energy and turn it into heat. The result is longer battery life and less heat produced. The same goes for cars, which lose a ton of their energy as heat, and even for fossil fuel power plants, which lose up to half of the energy created as heat.

Eneco is already in talks with BMW, Apple, Dell, the US Military and NASA. There's no word yet on how much the devices will cost, or what dangerous materials they might or might not use, but the technology sounds extremely promising. Representatives say that the first devices will be in use by 2008, but the time line for consumer devices is unspecified.

Thermoelectric Peltier effect - is not
written by Christopher Haase, November 25, 2006
There may be 1000's of pseudo patents on this kind of device.

I bought a great one on cheap viagra Ebay using heat from furance to power lights in my house (for free!)

NASA & the U.S. have used 40-60% efficient ones to power satellites & other “stuff” for decades

Not new, not news… just “Green Marketing”

Much like Bio Fuels, Electric Cars & Hybirds have been around for nearly a century. The only thing that has change is “Eco-Marketing”. Seriously, people take credit everyday for someone else’s ideas. There have been passive energy generation devices that are equally inefficient used for decades. If they utilized power better, everyones house would have one.

Do a simple google or patent search on anything that appears to be a new “Eco Idea”…. Most often you’ll find the only new info about the “new” device is the buy 100 mg cialis name of the company.

While you should watch out for the new generation of “EcoScams”, I think it is levitra online prescription AWESOME that so many people are looking for greener solutions and I support ALL companies that offer truly innovative, safer & environmentally sound solutions.

P.S. There are still 100's of great ways to look here levitra online in canada use Peltier energy, I just questioning the obvious "What's green is new" Title on this one...
Or We can use our NUKE decayed waste to power our houses the same way (Russians did this for over a decade)

What's New

You're right, and I did a bit more research after I posted and found similar information. The difference here is that peltier devices generally use a vacuum to separate the plates, which makes the devices difficult to create with high efficiency. Using a semi-conductor allows Eneco to have a device that works well, albeit not at optimal efficiency. They also have a higher chance of being mass produced, are less fragile, and very small.

That being said, we're all very tied to press releases and announcements of devices, and it is too bad that there are so many innovations that didn't catch on in the past. Hopefully, the second time around, these devices will find their way into more applications.

Peltiers (which do pill price viagra not involve a vacuum) are used by every two-bit computer overclocker. Pump electricity in, and a temperature difference is formed between the cheap generic online viagra plates.

You can buy one for $50 and use it NOW. It's just very inefficient.

Complete hype for a many-decades old invention (opposed semiconductor stack between two plates) that is surprising to people the first time they discover it.
Regarding laptops
written by anon, October 22, 2007
Thermoelectric devices have been around for a long time, as people above have mentioned. The only things that this company may have accomplished are that they seem to buy cialis pills have improved efficiency some and possibly made them more durable.

When it comes to laptops, though, if any are included in future models they will not have a significant effect on battery life and hot laps (at least not at the same time). The key problem with laptops is that the electronics inside produce a lot of heat and if it isn't removed it will damage the components.

Adding TED to recharge your battery using the internal heat would make it harder for the heat to get out and thus damage the laptop. The only way this could be avoided is if they made a larger heat sink or used a stronger fan to dissipate the heat, which means you'll probably have a hotter lap instead of a cooler one. (if they use a very powerful fan it would sound awful but you may get slight (probably unnoticeable) heat and battery life improvements.)

If instead you powered the TED to force more heat into the air being vented from the laptop it will probably help the laptop's temperature, but it will hurt battery life since the TED draws power from it.
