The ThermoHelioDome has been winterized to prevent the bulbs from freezing by using a hot water heater to provide heat to circulating water. Track the performance of the dome’s heater here and the mean radiant temperature here. Eventually, the entire sensor network will be posted online.
New York Times thermal imaging article
The NY Times ran an interesting article on thermal imaging, a tool we use in our research to study how heat moves in and out of surfaces. It gives a nice overview of the technology, as well as some interesting application and business models (like essess.com)

Passive Radiant cooling surface material Nature Paper (Fan @ Stanford)
The group fo Shanhui Fan published a paper in Nature, “Passive radiative cooling below ambient air temperature under direct sunlight.” I demonstrates how a nanostructured surface and shift the wavelength of radiant emission into a band where the atmosphere is transparent, greatly increasing the thermal gradient and cooling potential by radiating to the sky. They were able to cool the surface to 4.9 degrees C below the ambient air temperature in sunlit conditions.

ThermoHelioDome Construction + DAQ
Watch all aspects of our radiant cooling dome construction, from robot foam fabrication and hot wire cutting to truck rigging and gorilla gluing. At the end, check out the in-house design for mean radiant temperature sensing and the wet-bulb temperature depression through the cooling reflected by the dome’s dishes, viewed in the IR spectrum.
