Geoleaf: A variable greenhouse envelope for energy-efficient food production
We have developed an energy-saving, inexpensive variable insulation system that can be switched between two states. In one state, the system
acts as a sunlight transparent window and the other state of the system acts as a highly thermally insulated ceiling. This variable light transmission /
thermal insulation system uses readily available, inexpensive materials and switching between the two states requires only a simple low-power, inexpensive
actuation device. We believe this new system represents the first truly practical and cost-effective variable light transmision / thermal insulation system
for greenhouse food production.
