okay with the  gem quality MANufactured
diamonds and silocones heat barrier of 200 degrees
fahrenheit, diamonds just may supplant silicone seeing
as how diamonds can withstand approximately ten
times that amount...

silicon chips can only RESIST 20 volts or so.... diamonds up to 200

what will it do to electronics when 3 tons of silicone can be replaced with say 50 pounds of diamond based electronics and hardware in a standard electric passenger train?  Maybe soon electricity will be sold at restaurants in electric car parking spaces and the cost of it will go up... At least you can make your own electricity...

where will this take the future of computing, laptops may VERY soon last for DAYS.... the chevy volt 230 mpg may be something to scoff at when the power to weight can be diminished by utilizing diamond technology.

hmm........

saw this a week or so ago...

DIY thermal compound for improved CPU cooling, using diamond dust

Voltage is not an obstacle for computational speed. Also impedance is irrelevant in a closed, DC system that powers PCBs.

We're now way beyond my feeble electrical engineering knowledge with the boxes on our desktops, but I know that it's black box waveguide voodoo.

i think the voltage coolness is to keep things like inverters and motors from getting too hot... i wonder if soon diamond hardware in electric  cars will push the gasoline engine in the corner of the engine compartment as just a little 2 hp generator that comes on to charge up the batteries when your NOT driving... it would be sweet..

using diamonds an inverter or power converter could be realy small and not draw so much juice just turning fans to keep it cool ...

diamond dust cooler? sweet .. I still like the saab 9000 transmission
cooler- fish tank pump motor peltier rig you talked about making,
that is a 10!

The scientific (non-engineering) explanation for why chips get hot has nothing to do with the silicon.

The reason that materials approach superconductor states as they approach absolute zero has to do with the fact that logic gates *need* to waste some energy.

Think about this: You have an OR gate in your chip. You have one high input and one low. Perfect, you output +5v and nothing is wasted. But suppose you have two high inputs - what happens then? Well, you still only output +5v, that other +5v has to go somewhere. It's dissipated as heat. Multiply that by several hundred million for any modern semiconductor, and that's where all that heat comes from.

EDIT: Didn't finish my thought

What I'm trying to say is that gold at -30 degrees Celsius is most likely about the same level of conductivity as a diamond at room temperature. A peltier device (active heatpump) will get your chip well below that at idle, even under load if it's water-cooled.

does the -5  dissipate into the silcone?  i thought it just dissipated into the ground....  the point of the diamond hardware is for the diamond
to replace the silicone insulating the transistors allowing them to run
much hotter i thought... im really intrigued by this but outta time, im gonna have to read up on it cause im not sure.... but i dont think that diamonds conduct electricity at all ... so diamonds as light weight heat barriers in motors and inverters as well as to supplant silicone in chips, hopefully keeping the heat where it needs to go.... my question is if we break the heat barrier of silicone... at what point will the gold melt?
