      adjacency - between - deep geothermal - gyrotron - microwave energy - drilling - use oil & gas industry drilling expertise - rehabilitate old mines - adjacency statement - gyrotrons pulse high energy microwave energy in nuclear fusion experiments - Woskov thought of applying to vaporing rocks - Quaise was incorporated to explore the possiblity of using gyrotrons to drill up to 20 miles down to tap into the earths heat energy to heat water and drive steam turbines in existing coal-fired and gas power plants - oil and gas industry drilling expertise can be repurposed for this job - as well as all the abandoned resource wells around the globe - Such heat can provide a stable 24/7 base load energy for most of humanity's energy needs.

      implications for energy transition - This is a viable option for replacing the dirty fossil fuel system - It has the scale and engineering timelines to be feasible - It is a supply side change but can affect our demand side strategy - The strategy that may become the most palatable is one of a "temporary energy diet"

    1. Monseigneur de Hemptinne watched Yeke people working at Dikuluwe as late as 1924. They worked in the dry season and stopped when the first rains arrived. The mining camp was near a stream where millet could be planted. Women and children collected malachite from the surface, while men used iron picks to excavate pits and shafts, using fire to crack the rocks when needed. The mines were between 10 metres (33 ft) and 15 metres (49 ft) deep with galleries up to 20 metres (66 ft) long. The ore would be sorted and then taken to a nearby stream for concentration before being smelted

    1. Northern Transportation Company Limited (NTCL)

      Northern Transportation Company Limited, which began as Northern Waterways Limited, was a transportation company that assisted in the radium and uranium mining on Great Bear Lake (Prince of Wales Northern Heritage Centre). The company had little assets including two barges and a tugboat. They were acquired by White Eagle Mines in 1934 and their name was changed to Northern Transportation Company Limited (NTCL). In 1936, NTCL was acquired by Eldorado Gold Mines Limited, which also used NTCL to service their mining sites. In 1937, NTCL purchased steel hulled boats for transport. An Eldorado mine closed in 1940, so NTCL began working on the Canol Project in 1942 to transport materials to build a new pipeline. In 1944, the Canadian government took control of NTCL and the company became the main transporter of uranium ore. NTCL took control over the Hudson Bay Company’s transport system in 1947. NTCL also assisted with construction of the DEW line. NTCL was sold to the Inuvaluit Development Corporation and Nunasi Corporation in 1985. NTCL’s main fleet was located at the Port of Hay River in 2015. NTCL was responsible for providing goods to 22 communities through specially designed shallow barges (Government of Canada). NTCL declared bankruptcy on December 30, 2016 and were acquired by Alvarez and Marsal Canada Inc.( Alvarez and Marsal Holdings, LLC).
