National Renewable Energy Laboratory’s Eric Kozubal co-invented an air conditioning system that’s energy efficient while incredibly effective at both cooling a building and managing its humidity levels – the first time both of these processes have been fit into a single machine. Kozubal recently talked to us about his invisible technology, its road to commercialization, and the effects it will have on industry. Question: This is a perfect example of ‘invisible technology.’ How would someone walking into a building know the DEVAP was being used?
