Another one of Google's secret projects is becoming its own company.


														
							

A new startup called Dandelion, born from the secretive and futuristic lab “X” of Google’s parent company Alphabet, says it will offer affordable geothermal heating and cooling systems to homeowners. Existing systems are typically expensive with big upfront installation fees, discouraging homeowners from adopting the technology.

Home geothermal systems tap into the ground’s energy. Because geothermal energy is generated and stored in the earth, these systems use plastic pipes in the ground and a pump inside the home.

In the winter, water located inside the pipes absorbs heat from the earth. The pump then turns it into warm air. In the summer, the pump pulls warm air out of the home and the pipes disperse the heat back into the ground.

Installing the pipes — called “ground loops” — under someone’s lawn is a traditionally invasive, messy process. It involves using wide drills that dig wells more than 1,000 feet underground.

Dandelion’s drill is fast and lean, allowing for only one or two deep holes a few inches wide.

The system will cost between $20,000 and $25,000, compared to conventional systems priced as high as $60,000.
