I believe Two Bit DaVinci covered this a while back, but I could be wrong, oh well, summary:

This video talks about a new technology that could revolutionize geothermal energy. Geothermal energy is a clean and renewable source of energy that uses heat from the Earth’s core to generate electricity. However, traditional drilling methods cannot reach the deep, hot rocks that contain the most geothermal energy.

The new technology, developed by Quaise Energy, uses a microwave beam to vaporize rock. This allows them to drill much deeper and faster than traditional methods. The microwave beam is created using a gyrotron, which is a device commonly used to heat plasmas in fusion reactors.

Quaise Energy is planning to test their technology in the field later this year. If successful, this could mean that geothermal energy could be a major source of clean energy in the future.

Here are some of the key points from the video:

• Traditional geothermal drilling methods cannot reach the deep, hot rocks that contain the most geothermal energy.
• Quaise Energy’s new technology uses a microwave beam to vaporize rock, allowing them to drill much deeper and faster.
• The microwave beam is created using a gyrotron, a device commonly used to heat plasmas in fusion reactors.
• Quaise Energy is planning to test their technology in the field later this year.
• If successful, this could mean that geothermal energy could be a major source of clean energy in the future.

I hope this summary is helpful!
