Kronos Advanced Technologies claims that's the way we're headed
Lately, heatsinks and traditional fans have become so large that they are beginning to be obstructive and are sometimes too heavy. This is an issue on the graphics processor front in many ways, as there isn't enough room for large heatsinks,
yet GPU thermal exceeds that of high-speed CPUs
A company called
Kronos Advanced Technologies
is working on a method of
removing heat from devices such as CPUs by using ionic discharge to
create a fluid motion of air. This technology has been around for a few years and is used in products such as ionic air filters, which have no moving parts but still move volumes of air and create quite a strong breeze. The same concept is being applied to micro processor cooling.
Despite the advancement however, the volume of air moved over the CPU core is still small because the core surface area is small. Heatsinks are used to increase surface area of the hot surface, so that when air is moved over the fins, more heat can transfer to the air. The Kronos' device will attempt to remove hot air away from the processor core directly without the need for heatsinks. With this method, the velocity of air being moved needs to be extremely fast in order to compensate for the lack of surface area -- and speed is something that ionic air "movers" lack.
Right now, Kronos is still working on prototypes, which it claims are scalable from very small micro coolers to large scale sizes. Power requirements also appear to be quite steep at this point in time. One of Kronos' demonstration shows a heated area being reduced from roughly 50C to 25C using an ionic cooler, but the power supply required around 8.5kV, or 8500 volts, to stay stable.

In europe its 220-230 volts...well in Denmark it is.
The difference between this voltage and the 110 in usa is that the amperage is half. thus giving the same amount of power.
Really dont know whats its called on english but there is safety in houses normal that shuts of the power if a thing like the bobby pin in power out happends. That has saved many lives I guess. Its both to protect the installation so the house dont burns down plus to protect humans.
I learned in school that Amperage kills people not volts!
Thats the most simpel thing to remember. A 100.000 volts static zap wont kill you due to the lack of amperage....and thats enough proof.
But this new hot technology needs 8500kw to work...and I almost bet that include more amperage than the firm behind the test wanna tell us at the moment. I for sure will not touch anything of that..I guess you are dead then.
The process of this "masterpiece" is likely very power dependent...otherwise we would have seen it before. Another part is that most emit lots of sparks and static electricity in the machine....not good at all for sensitive equipment. Its just one small zap away from making it a very DEAD PC.
