Part 6/9:
Advanced microwave technology allows for penetration into much deeper and hotter geological formations than previously possible. While traditional drilling methods might average around 100 meters per hour, the microwave-based drilling could feasibly achieve a rate allowing for a 10 km borehole to be drilled in approximately 100 days. The minimal wear on equipment could change the geothermal landscape as we know it.
Field Test Plans and Future Outlook
Excitingly, Quazar plans to conduct field tests later this year with two machines, one operating at 100 kilowatts and another at 1 megawatt. These tests aim first at depths of 1000 meters before moving on to more ambitious projects reaching 3-5 km, ideally in high geothermal gradient zones.
