Quaise Energy, a Boston company, is using tech from nuclear fusion experiments to reach new depths. *"12 miles down", that's 19 kilometers for team metric.

>"Quaise Energy, a startup based in Boston, is taking a third approach: digging deeper—and using more heat—than any company has before. To do so, it’s refashioning a millimeter-wave drilling technique from nuclear fusion experiments."

Globally installed geothermal capacity has grown by 982% between 1975 and 2020, and an astonishing 70% since the year 2000. 📈

While the theoretical potential of geothermal energy is enormous, the technology still accounts for less than 0.2% of the global power supply.

"Quaise’s chief executive officer, likens it to “a big cousin of the microwave in your kitchen”—only with 1,000 times more power. “It’s a fairly mature technology,” he says. “We just use it for this purpose.”
