Geothermal is fantastic for heating. Speaking as an Icelander, we have so much hot water in Reykjavík that we even use the residue to keep our pavements clear of ice in winter. Pipes under the sidewalks carry exiting geothermally heated water from nearby houses. It's great technology and has served us well.
"There are clever, hardworking, stupid, and lazy officers. Usually two characteristics are combined. Some are clever and hardworking; their place is the General Staff. The next ones are stupid and lazy; they make up 90 percent of every army and are suited to routine duties. Anyone who is both clever and lazy is qualified for the highest leadership duties, because he possesses the mental clarity and strength of nerve necessary for difficult decisions. One must beware of anyone who is both stupid and hardworking; he must not be entrusted with any responsibility because he will always only cause damage." -- Kurt von Hammerstein
