The earth under your feet costs nothing - and it stays cool year-round.\u003c\/i\u003e\u003c\/p\u003e\u003cp\u003eEarth tubes - also known as earth-air heat exchangers or geothermal cooling tubes - are one of the oldest passive cooling technologies on the planet, used in some form since ancient Persia, and one of the least known among modern homeowners and builders. A length of buried PVC pipe, a gravel bed, and a cracked window are all it takes to deliver free air conditioning for the lifetime of your home - passively, silently, and at zero operating cost.\u003c\/p\u003e\u003cp\u003eThis is the most comprehensive DIY guide to earth-air heat exchanger design and installation ever written for the existing homeowner, new home builder, homesteader, and off-grid community. It covers everything from the physics of geothermal cooling to the hands-on trench work, from ancient Persian qanats to the latest research on backfill materials and corrugated pipe performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eInside you will find: \u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eA complete honest pros and cons assessment - including when earth tubes are NOT the right choice for your site\u003c\/li\u003e\n\u003cli\u003eStep-by-step installation from trench planning to interior finishing\u003c\/li\u003e\n\u003cli\u003eThe Larry Larson slit-and-sand method - the highest-performing DIY earth-air heat exchanger design documented\u003c\/li\u003e\n\u003cli\u003eTwo original designs: angled tubes for condensate water collection, and spiral tubes for small lots and bermed homes\u003c\/li\u003e\n\u003cli\u003eHow to size your system for humid climates, high water tables, and off-grid communities\u003c\/li\u003e\n\u003cli\u003eWhat goes wrong - and how to spot it before it becomes a permanent problem\u003c\/li\u003e\n\u003cli\u003eEvery other low-cost cooling method worth knowing about, and why earth tubes outperform most of them\u003c\/li\u003e\n\u003cli\u003eCommunity-scale geothermal cooling for ecovillages and intentional communities, with documented case studies and real performance data\u003c\/li\u003e\n\u003cli\u003eHow earth tubes pair with passive solar design, rocket mass heaters, and thermal mass construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe book also covers the history you did not learn in school: 3,000-year-old Persian qanats that cooled entire desert cities without electricity, the termite mounds that inspired a net-zero office building in Zimbabwe, and the prairie dog burrow that applies Bernoulli's principle more elegantly than most HVAC engineers.\u003c\/p\u003e\u003cp\u003eWhether you are building new, retrofitting an existing home, living off-grid, or designing housing for a community, this guide gives you everything you need to put the earth's stable temperature to work - permanently, passively, and for the cost of a weekend's worth of pipe and a rented trencher.\u003c\/p\u003e\u003cp\u003e\u003ci\u003eCool your house without AC.
