Geothermal looks so cool, I'm pretty sure I'll be in my house for at least the next 10 years so it's tempting. My back yard is full of roots though and I'm worried I couldn't dig the trench without killing my shade trees, which I love. I'd probably rent an excavator though, I've done enough digging to know I never want to do it by hand again.


				

				

						

							

								
							

						


						
					

				
			


			

	


			
			 
				
					

						
							



	

	

		
			

			

				

			

		

			


				

					
It does! I'm in a similar situation with shade trees, but seriously thought about lopping them all down and doing it anyways. It was tempting to put a big "geothermal!" mark at COP5+ on the graph, but it was already too crowded.


Had to cut almost everything about ground-source stuff for length, but I think it's the future in cold climates, and Europe is making a serious mistake trying to push air-source units rather than street-level ground source. There's a tremendous amount of wasted heat flowing down every sewer pipe without even having to do any digging, and ultra-low-temperature local cogeneration would make even a simple gas turbine about 260% efficient.


				

				

						

							

								
							

						


						
					

				
			


			

	


			
			 
				
					

						
							



	

	

		
			

			

				

			

		

			


				

					
I'd like to read your write up of the geothermal material that you had to leave out. Any chance of a supplementary post?


				

				

						

							

								
							

						


						
					

				
			


			

	


			
			 
				
					

						
							



	

	

		
			

			

				

			

		

			


				

					
Next post is focused on all the culture war you could see oozing from the seams in this post lol.


After that I was thinking about a electrical generation post. Unfortunately I don't have any firsthand experience with ground-source heat pumps, and there's so much propaganda around all things heat-pump that I wouldn't want to post my research as trufacts without independent confirmation. Maybe Stefferi could help with that.


				

				

						

							

								
							

						


						
					

				
			


			

	


			
			 
				
					

						
					

				
			
		

	



						
					

				
			
		

	



						
					

				
			
		

	



						
					

				
			
		

	




	

	

	

	

	

	
	

	
	

	
 















	






			
			

		

		
			
				


	

		
	


	


		
What is this place?

		

			This website is a place for people who want to move past shady thinking and test their ideas in a 
			court of people who don't all share the same biases. Our goal is to 
			optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.



			The weekly Culture War threads host the most 
			controversial topics and are the most visible aspect of The Motte. However, many other topics are 
			appropriate here. We encourage people to post anything related to science, politics, or philosophy; 
			if in doubt, post!


			
			Check out The Vault for an archive of old quality posts. 
			You are encouraged to crosspost these elsewhere.
		


		

		
Why are you called The Motte?

		

			A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, 
			it's an element in a rhetorical move called a "Motte-and-Bailey",
			originally identified by 
			philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial 
			but high value claim to a defensible but less exciting one upon any resistance to the former. He likens 
			this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for 
			the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired 
			propositions to which one retreats when hard pressed."



			On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.
			
		


		

		
New post guidelines


		

			If you're posting something that isn't related to the culture war, we encourage you to post a thread for it.
			A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts
			such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a
			submission statement. A submission statement is required for non-text sources (videos, podcasts, images).



			Culture war posts go in the culture war thread; all links must either include a submission statement or
			significant commentary. Bare links without those will be removed.



			If in doubt, please post it!
