Memory shape material cooling (elastocaloric cooling) is a new application for shape memory alloys. Materials that exhibit shape memory will return to their original cast or molded form when heat is applied.

Silicon based aerogel insulation is a lightweight material with a thin profile that has insulating properties almost three times that of traditional fiberglass insulation.

Permanent magnet AC motors (PMAC) are just like standard induction AC motors except they have permanent, rare-earth magnets attached to their rotors (the center part of the motor that spins).

Vortex water treatment is specifically designed to reduce energy use during the resurfacing of ice rink slabs. An ice slab is the core feature of an ice rink, and the quality of the ice surface is critical.

Magnetic refrigeration is an emerging refrigeration process. It utilizes a completely different thermodynamic process to produce cooling compared to traditional vapor-compression refrigeration cycles.

It takes far less energy to produce these vibrations than to produce the amount of heat used in standard dryers. In fact, they are three to five times more efficient than current dryers.

Screw-in LEDs are lamps that directly replace metal halide lamps without fixture changes or rewiring. The new lamp screws into the existing metal halide fixture.

Packaged refrigeration system controllers are used as a central control system for commercial refrigeration systems in grocery or convenience stores.

The five technologies lack refrigerants that contribute to climate change. That does not mean each is free of any impact. All electric and gas powered devices have impacts.

Magnetic bearing chillers have very high efficiencies, particularly at partially loaded conditions, even compared to other variable frequency drive (VFD) driven chillers.
