Impact Technologies LLC (Impact) would utilize DOE and cost share funds to further develop the intense millimeter wave (MMW) radiation technology for ablation/vaporization and melting of rocks in drilling to deep geothermal formations. Phase I of this work would consist of laboratory bench testing and prototyping of the technology and analysis of results. Laboratory work would be conducted at Massachusetts Institute of Technology's (Cambridge, MA) Plasma Science and Fusion Center gyrotron facility and Rock Mechanics Laboratory.
