"Indeed, gyrotrons capable of generating continuous energy beams over a megawatt in power are now becoming available, and that's amazing news for deep drillers. "The scientific basis, technical feasibility, and economic potential of directed energy millimeter wave rock drilling at frequencies of 30 to 300 GHz are strong," wrote Ogilvy. "It avoids Rayleigh scattering and can couple/transfer energy to a rock surface 1012X more efficiently than laser sources in the presence of a small particle extraction plume. Continuous megawatt power millimeter-waves can also be efficiently (>90 percent) guided to great distances (>10 km) using a variety of modes and waveguide (pipes) systems, including the potential of using smooth bore coiled and jointed/ joined tubing.""
MIT spin-off Quaise says it's going to use hijacked fusion technology to drill the deepest holes in history, unlocking clean, virtually limitless, supercritical geothermal energy that can re-power fossil-fueled power plants all over the world.
10:23 PM
"The next step is commercial genius: Quaise plans to take advantage of existing infrastructure like coal-fired power plants, which will eventually be mothballed as emissions restrictions become ever tighter. These facilities already have enormous capacities to convert steam into electricity, as well as established commercial operators and experienced workforces, and they come conveniently pre-connected to the power grid. Quaise will simply replace their current fossil fuel heat sources with enough supercritical geothermal energy to keep the turbines spinning indefinitely without ever needing another lump of coal or puff of methane.
Quaise expects to re-power its first fossil-fired plant in 2028, and then go on to refine and replicate the process all over the world, since the heat should be available absolutely anywhere on Earth with this drilling technology. There are somewhere upwards of 8,500 coal-fired power plants around the world, totaling over 2,000 gigawatts of capacity, and they'll all have to find something else to do by 2050, so the opportunity is clearly mammoth."
From Their Website ( https://www.quaise.energy/ ) :
"Geothermal does not require any fuels and does not produce any waste. It’s truly renewable, abundant, and equitable for all, even in the most challenging energy environments."

Frequency response is a measure of the magnitude of the output of a system compared to its input, as a function of frequency. In other words, it describes how accurately a system reproduces each frequency of an audio content, in terms of amplitude.
