Passive Cooling
The science behind our materials
Atmospheric Absorbance
The atmosphere of the planet is transparent at some wavelengths and not at others. Due to the Greenhouse Effect, CO2 and other greenhouse gasses in our atmosphere absorb particles of light, causing the bonds between the atoms to vibrate, effectively trapping the photons and heating up the planet.
For example, this is why we see sunlight at the surface of the planet— visible wavelengths are not absorbed by the atmosphere. We are focused on targeting these spectral windows, but at longer wavelengths that are invisible to the naked eye.
Reverse Greenhouse Effect
We make hyper-emitters that selectively emit in the wavelengths where the atmosphere of the planet is transparent.
When we do this, it is like taking the emitter out of an insulating thermos (the atmosphere) and exposing it to the vast cold sink of space. Then, due to the second law of thermodynamics (heat always goes from hot to cold) the material gets cold without any additional energy or electrical input.
In other words, we are making use of the significant temperature differential between the surface of the planet and outer space, preventing atmospheric absorption by emitting specific wavelengths of light, and allowing the heat to go straight into space.
We like to call this a Reverse-Greenhouse Effect because heat is whisked away from the planet instead of getting trapped.
Engineered using a deep understanding of photonics and thermodynamics, our films reduce emissions, fuel costs, waste, and extend asset lifetimes.
Our pilot projects will revolutionize industries
Refrigerated Trucking Industry
Pilots with refrigerated trucking fleets will consist of at least two trucks, one as a control unit and one with the materials installed. We are currently organizing pilots locally, nationally and internationally with large grocery chains, cold chain logistics companies and refrigerated transport manufacturers. For example, utilizing two refrigerated trailers, one with and one without the cooling materials, we can directly measure the difference in power consumption (fuel savings) between the two trailers under the same conditions.
Energy Systems Projects (BESS, Inverters, Transformers)
Pilot testing in this industry is based on multiples of two units (control and experimental) in the same ambient conditions (wind, solar radiation, air temperatures, etc). The tests include, for example, having the same alignment with the sun’s trajectory and similar thermal profiles. We are currently organizing pilots with a number of large utilities.
Solar Photovoltaic Projects
Utilizing two solar panels, one with and one without the cooling material, we can directly measure the difference in power output and surface/ambient conditions between the two. We are currently organizing pilots with a number of panel manufacturers and large utility companies.
