The Globe Drill GT3000 mobile drill rig takes about two semis to haul, but can drill holes as deep as some oil and gas rigs that take 40 or 50 semis to move. It has the potential to revolutionize the small scale geothermal energy market. Apparently the Chilean government was also in discussions with the rig’s creators to use it drill a hole to rescue the trapped miners if the three smaller rigs they used didn’t work. The rig’s creators are currently drilling a 17-in diameter, 3-km deep test hole in hard rock near the creator’s Merredin, Australia work shed. [Source: Merredin Wheatbelt Mercury via AGC SmartBrief.
