Right now it's not quite as efficient as your traditional cooler as it takes roughly 1.75W to dissipate 11W of heat, while your traditional desktop heatsink+fan takes the same amount of power can dissipate at least 10x more than that. Nevertheless, it's a very interesting piece of tech and I look forward to seeing future iterations.

Also, the audacity of the bald slant calling himself an American. lol just go fuck yourself MAH UNG.

interesting approach this guy has. I thought it was going to be a peltier chip based design - wasn't expecting a mechanical system like this. I would think it would be very sensitive to dust and contaminants.

according to the interview, this thing operates at a high pressure than conventional fans, allowing you to put a dust filter on the inlet port of the chassis and it will still be strong enough to overcome the additional air resistance

Strong enough until a hair or some other stray contaminant slips into the chip and clobbers a few hundred of his nanobellows ;)

I wonder how long the MEMS elements last.

I'm skeptical of this.

Hopefully they don't price themselves out of the ballpark to prevent broad adoption. Even quality fans are relatively cheap. Granted, most laptops have extensive heat pipes and various means to extract it out of the device. Copper isn't cheap. Maybe this provides enough room to compete not against a fan, but fan plus extensive cooling pipes and so on.

In the video they explain how due to thickness and heat distribution a vapor-based heat pipe is recommended. The small, hot area of the CPU needs to be spread over the entire surface of this larger cooler.

The biggest benefit is in its claimed quiet operation. Laptop fans can get annoying, especially the way they speed up and slow down in response to what you're doing.

I explained it poorly. For example, my laptop has roughly 12"x2 + odds and ends of heat pipe. That's two feet+ of copper. I'm hoping they can get by with something like 1/3 of the amount of copper and it's enough to offset the price difference.

Aluminum is cheap and conducts heat better than copper.

Copper is around twice as thermally conductive as aluminum. It's more expensive but that's why it's used.
