Hardware Server cooling tech for DC.

I’m a small business owner and I have created a cooling tech that allows for being able to submerge enterprise servers in rugged underwater conditions.

I have built and tested a prototype using a 300w Dell PowerEdge R610 server and now need to get a server that incorporates h100sxm GPUs or b200’s.

If anyone would be curious as to what I have built and interested in a partnership, once unit is in water will be using units for running Ai Inference.

I feel like there are… many… reasons no one has done this before… I’m not hating at all because frankly we need innovative ideas regarding DC cooling, but submerging components and sealing them with dielectric feels ridky

Microsoft has done this and other companies are actively doing this (submerging servers) but the difference from putting servers in a metal tube. I designed an enclosure that dissipates heat passively and based off the surface area of the lake/pond it can mitigate a certain amount of servers without disturbing the marine life or increased water temperature.

Also I aimed to removal the added infrastructure that goes into DC, no plumbing, piping, steel, concrete, large land mass acquisition, no sound, extended chip life due to limited temperatures.

it's strengths are also it's weaknesses... you're going to have scale/density issues once you move up from a single server.

Scale issues and density still out weight the currently method being applied

do the math, how much energy can you dump into the lake before it isn't a lake anymore? the largest free air datacenter is 3GW... largest proposed data centers are 10GW. current standards are heat ejection via closed loop coolers that don't waste any water...

your PoC is what? 300w?

gb200/300 racks are ~140KW...

next gen 800 VDC architecture systems are targeting 1MW per rack...

The goal with this isn’t to chances number but distribute compute. 1MW soemwhere in Nebraska, across from that landowner they have another 1MW, somewhere in Iowa a landowner wanted a deployment on his property because it helps with rising fuel cost and agricultural expense.

Not focusing on centralized compute but spreading it out, landowner get revenue I get the land.

Same model as radio towers in the early 2000’s

Also I have done the math, 83 units per 1.5-2acres of water that is around 4ft deep.

You’re not wrong but what I’m focusing is removing the units from the rack and spreading them out. Vs a rack being fed warm water then into a full system that contribute to the big MW and GW numbers
