DIY well drilling / trench digging for GSHP

It seems to me that the #1 obstacle in building a geothermal system is the digging. Even the heat pump itself isn't too difficult as you can simply buy an pre built unit; albeit for a lot more money than one can make their own. There have been some valiant efforts on this front in the heat pump manifesto but most people there that have described their processes in any great depth have all run into various problems with getting down to great depths, such as 100 - 200 '. Let us here discuss the methods of drilling and digging at home without subbing out the work to a well driller or excavation contractor.

I will keep the first post of this thread updated as time passes with links to relevant posts and news.
