I have a blind spot on vertical ones because they're definitely not an option here; my well wouldn't qualify as "marginally acceptable" as a water source in most places, and you'd have to be impossibly lucky to get a shaft with enough water layer and flow to work as a ground source. In a place like florida they'd be amazing, but in florida you could just warm your pool instead.


Geothermal in general has that "as much art as science" problem. There's research asking "wait, how much heat could pump from the ground below a city without causing problems?", and there's not much in the way of hard numbers yet, especially in the cold climates where a ground source is important.


That's one reason I think co-gen will be a big deal. Having a huge volume of power plant condensate to work with takes out the guesswork, and there's no technological advances needed over current high-temp cogen systems.


				

				

						

							

								
							

						


						
					

				
			


			

	


			
			 
				
					

						
							



	

	

		
			

			

				

			

		

			


				

					
In yet another victory for thermodynamics; it turns out that a large thermal mass is just fucking better for the shit we want to do if you can max out capacity.


It's like that old tmblr post; that no matter what you  are doing the most efficient form will always be whatever the train equivalent for the field is.

is it entire interesting part? Or have they got interesting examples?


				

				

						

							

								
							

						


						
					

				
			


			

	


			
			 
				
					

						
							



	

	

		
			

			

				

			

		

			


				

					
A conceptual train.


Imagine you are, for example, lifting mass into orbit, or moving people between floors in a building, or cooking food, or digging a big hole.


What is the most efficient way to do all those things?  Orbital elevator theoretically/BIG ROCKET currently, Escalator, BIG pressure cooker, BIG bucket wheel excavator.


The more the spirt of the thing is akin to a train, the more efficient the thing is, and also the more RIGHTOUS the thing is because trains are fucking sick


				

				

						

							

								
							

						


						
					

				
			


			

	


			
			 
				
					

						
					

				
			
		

	



						
					

				
			
		

	



						
					

				
			
		

	



						
					

				
			
		

	




	

	

	

	

	

	
	

	
	

	
 















	






			
			

		

		
			
				


	

		
	


	


		
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!
