2024年8月1日 · MMW drilling transmits vast amounts of concentrated energy downhole, and the circulating gas is highly effective at removing small cuttings from extreme depths. Both tasks are tall orders for conventional drilling technology. However, conventional drilling outperforms MMWs in sedimentary rock.

FIG. 3 Millimeter wave drilling will unlock the most abundant and powerful clean energy source on Earth by allowing us to drill as far down as 20 km to reach temperatures up to 500° C.

• Overall Objective : Further develop millimeter wave (MMW) radiation technology for drilling and lining/casing wellbores- by the melting and ablation / vaporization of rocks.

2020年2月19日 · AltaRock Energy is leading an effort to melt and vaporize rocks with millimeter waves. Instead of grinding away with mechanical drills, scientists use a gyrotron—a specialized high-frequency microwave-beam generator—to open holes in slabs of hard rock.

2022年12月8日 · To tap into this natural power, engineers must devise a new strategy for drilling a dozen miles into Earth, deep into rock. An MIT spinoff company believes it has the answer: millimeter wave...

2022年2月25日 · Quaise's hybrid ultra-deep drilling rig will combine conventional rotary drilling with gyrotron-powered mm-wave directed energy drilling, pressure-purged with...

Millimeter Wave Drilling uses a continuous beam of energy waves between 30-300 gigahertz (millimeter waves) to melt, vaporize and bore through extremely hard and hot rock layers located deep in the Earth’s crust (Oglesby et al, 2014).

2022年7月1日 · Quaise Energy has proposed adopting existing technology from the nuclear industry, high-power millimetre waves, to drill holes to even greater depths enabling geothermal energy plants to be...

2014年12月30日 · To demonstrate MMW beam drilling capabilities a lab bench waveguide delivery, monitoring and instrument system was designed, built and tested around an existing (but non-optimal) 28 GHz frequency, 10 kilowatt (kW) gyrotron. Low waveguide efficiency, plasma generation and reflected power challenges were overcome.

2016年4月13日 · Woskov, a senior research engineer at MIT’s Plasma Science and Fusion Center (PSFC), is using a gyrotron, a specialized radio-frequency (RF) wave generator developed for fusion research, to explore how millimeter RF waves can open holes through hard rock by melting or vaporizing it.
