This technology looks to be promising enough in reducing effective carbon emission and green house gases , by elimination of CFCs and by reduction in Electricity consumption. Early commercialization of such technologies is the need of the hour.

I see the number now in the picture caption...175% more efficient. I assume it translates into roughly 3x the efficiency, meaning 1/3 the electricity usage.

The article states that this technology will allow refrigeration without the emission of greenhouse gasses. That sounds like a distortion to me, the majority of greenhouse gas emission for refrigeration systems is in the electricity they consume. Refrigerants are considered a greenhouse gas, but are not normally released in refrigerant operations. I assume this process still consumes electricity. Perhaps it is more efficient than a gas-liquid refrigerant cycle. Would be helpful if there the article contained some estimates on efficiency relative to current solutions in the article.

Does anyone know of other efforts to harness these thermoelastic shape memory alloys? I know that nitinol wire has been used in robotics, because when heated above its transformation temperature it can be stretched to 30 times its normal length, which it recovers when it cools. Also if you stretch it when its already cool, it will "remember" its original length when heated to its transformation temperature. I'm not familiar with other applications, though. Does anyone know of other efforts to harness these thermoelastic shape memory alloys?

An interesting technology for cooling with a number of potential applications. I wonder if it could be used to provide cooling for ICs that enable them to run faster while dissipating the die heat? Could the process be reversed like a heat pump to extract geothermal heat or to generate power? I would love to know more about how this works.

I'm sorry, but the Mrs. is not going to allow what's pictured in her kitchen.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
