Calling CO2, designated “R-744” as a refrigerant, an emerging technology may be a bit of a stretch. It was originally patented as a refrigerant in 1850; however, it fell out of use Read more
What is it? Membrane air conditioning is a category of cooling technologies that utilizes hydrophilic (attracted to water) membranes to dehumidify air efficiently as part of a cooling system.

What is it? Building operators have long abandoned hope of keeping everyone, everywhere comfortable. However, that’s because they have to set setpoints that occupants have little to no control over. Advanced setpoint controls take the guesswork out and allow users to give the system feedback directly. How does it work? Advanced setpoint controls are software Read more
What is it? Lithium ion batteries are familiar to most of us. In fact, there is a good chance one is powering the laptop computer or cellphone you are using to read this. Their high energy density and light weight makes them perfect for these applications. Forklifts have continued to use old fashioned lead acid Read more
Laser diode lighting is among several next generation lighting technologies that have emerged as a potential successor to LED lighting. It uses laser technology to provide light, as opposed to using diodes, gas, or a wire filament.
