ISRAEL - Heat and Cool with Only Air

Arno Froese

Imagine if you could heat or cool your home just by plucking the desired comfort level out of the air. Literally.

Israeli startup ThermoTerra is turning that vision into a novel renewable energy system that harvests energy from fluctuations in humidity.

“Water vapor in the air that’s absorbed onto or into an absorptive material transfers a significant amount of energy,” explains ThermoTerra founder and CEO Dror Zchori.

The ThermoTerra system is controlled by sensors embedded in the walls. Smart algorithms monitor when to bring in hot or cold air and when to release it. The algorithms learn owner preferences and automatically adjust the temperature accordingly. They can also tap into external weather forecasts.

The need for new technologies like ThermoTerra is indisputable: Some 40 percent of the world’s building energy is spent on heating and cooling, and buildings represent 30% of the world’s energy usage.

Zchori came up with the idea for ThermoTerra when he was building his own green home in Amirim, a rural Galilee community known for its environmental consciousness and where ThermoTerra is now headquartered.

By tapping into the natural fluctuations in humidity, Zchori discovered he could increase the temperature in his home from 12 degrees Celsius (53.6 Fahrenheit) to 26 C (78.8 F).

Going forward, Zchori can imagine ThermoTerra being used to cool cars. “When a car is sitting in the sun, it gets hot. We can cool it using evaporative water that’s harvested overnight.”

Whether in a car, a home or someplace even Zchori hasn’t thought of yet, “cooling and heating is a basic need. We are giving the power to the people to make their houses self-cooling and self-heating.”, 6 July 2022

Arno's Commentary

Not surprisingly, this originates from Israel. It’s cheap, it’s practical, and it’s environmentally friendly. That is the future due to the increased use of energy and natural resources, primarily burning fossil fuels.

In Biblical times, the fuel was often wood. We read in Isaiah 44:15-16: “Then shall it be for a man to burn: for he will take thereof, and warm himself; yea, he kindleth it, and baketh bread; yea, he maketh a god, and worshippeth it; he maketh it a graven image, and falleth down thereto. He burneth part thereof in the fire; with part thereof he eateth flesh; he roasteth roast, and is satisfied: yea, he warmeth himself, and saith, Aha, I am warm, I have seen the fire.” This type of success and prosperity led to idolatry: “And the residue thereof he maketh a god, even his graven image: he falleth down unto it, and worshippeth it, and prayeth unto it, and saith, Deliver me; for thou art my god” (verse 17).
