How much would I sell? None

In true Engadget form I'd give it away too!

To ameridan:

Temperature fluxuations are not dampened by the heat sink. Go back to you thermo book and look up sterling cycles. The liquid coolant cools absorbs the heat which is is not transfered until isothermal expansion of the cooling liquid. The liquid is then cooled at which time the heating blocks latent heat is building awaiting for the cooled liquid to transfer back. So there very much will be a build up of energy on the chip followed by cooling. Varibilty in temperature equates to variability in energy consumption.

You must look at the thermal efficiencies of the chip vs. the thermal efficiency of the process to decide which approach is more efficient. This sterling engine is only efficient when large temperature gradients are present similiar to heat pump cycles. So this believed savings is often wasted and thats the point. You believe you are recovering energy but at what cost? Chips become less efficient with increased temperature and variability. So you trade chip efficiency for that of an electric fan. Once this calcution is complete you likely will find the electric fan a more efficient use of resources since you'll exchange for load on the chip.

This seems like a great gimmick to displace consumers of their money in yet another green effort!

To drive the piston you are relying on expansion and contraction of the cooling gas/fluid which equates to a temperature fluxuation (excludes state changes and enthalpy of formation). This fluxuation would invariably change the efficiency of the chip likely in the +/- efficiency range. So the chip would likely draw .5 to 1 more watt if it used 20 watts.

Current fans running at full efficiency use .1-.2 watts. So this technology would likely use more energy than just adding a fan. At best the technology would be a energy wash with significant more cost in building and energy use to create the item!

What? 21MP 5D give a D300 a run for the money? HUH they would be different classes. Plus you'll never see the 1DsIII Sensor in another camera won't happen.

Nikon lenses (non-G) are made for full frame so they won't vignette? Nathan what are you talking about. You are implying that Canon's lenses are not designed for full frame? Your statement strikes me as absurd. All lenses can be prone to vignetting and it's often a matter of trade-offs. Plus go back and do your homework. Kodaks DCS-14N was known for horrible vignetting.

Digital also plays an effect in vignetting hence so many newly designed lenses.

me me me!!!

ME ME ME :)

This is nothing more than a small scale Rotovap. Common piece of equipment from Brinkmann, the same company that makes this item. The last rotovap I used was 20 years old so not sure how this is news worthy on a tech blog?

The vacuum unit is not included!

There are 2 major map producers, Telenet and Navteq. One is being bought by Nokia and the other TomTom. Sorry but there are more than 2 manufactures in the market and these 2 producers are working on vertical integration.

I don't see how this is good for the consumer in the long run or helpful for prices. I suspect the maps/software are the most expensive single component of a GPS unit.

Sounds like terrible news for the consumer! Will we see GPS price go up now?
