Dandelion Geothermal System
Geothermal systems are highly efficient, but they're normally custom-designed, which makes them extremely expensive. Google offshoot Dandelion is trying to change that with the Dandelion Air. By standardizing many parts, installation costs up to half of a traditional geothermal system, while reducing heating and cooling costs by up to 20% annually. Currently available to many homes in New York State.
