&lt;b>Comparison for &lt;a name=".trenchgeothermalcooling" href="http://www.ubasics.com/home/wiki/TrenchGeothermalCooling" class="">/Trench&amp;nbsp;Geothermal&amp;nbsp;Cooling&lt;/a> of &lt;a href="http://www.ubasics.com/home/wiki/TrenchGeothermalCooling?time=2006-09-23+23%3A32%3A22">2006-09-23 23:32:22&lt;/a> and &lt;a href="http://www.ubasics.com/home/wiki/TrenchGeothermalCooling">2006-09-24 22:08:22&lt;/a>&lt;/b>&lt;br />

&lt;b>Additions:&lt;/b>&lt;br />
&lt;div class="additions">Two&amp;nbsp;methods:&lt;br />
Air&amp;nbsp;tubes underground.  Lead into the&amp;nbsp;house &amp;ndash; as&amp;nbsp;a solar chimney pulls air&amp;nbsp;from the&amp;nbsp;house, cool air&amp;nbsp;is&amp;nbsp;drawn from the&amp;nbsp;ground tubes into the&amp;nbsp;house.  Romans used these for&amp;nbsp;cooling.&lt;br />
&lt;a name="geothermalheatingandcooling" href="http://www.ubasics.com/home/wiki/GeothermalHeatingAndCooling" class="">Geothermal&amp;nbsp;Heating&amp;nbsp;And&amp;nbsp;Cooling&lt;/a> uses a&amp;nbsp;heat pump to&amp;nbsp;both heat and&amp;nbsp;cool the&amp;nbsp;house using a&amp;nbsp;ground loop heat sink/source.  A&amp;nbsp;simpler method simply uses a&amp;nbsp;water pump, radiator, and&amp;nbsp;a&amp;nbsp;ground loop.  The&amp;nbsp;ground stays at&amp;nbsp;a constant 54F, so&amp;nbsp;a large enough ground loop would cool the&amp;nbsp;water close to&amp;nbsp;that temperature, which you&amp;nbsp;can then use&amp;nbsp;to&amp;nbsp;cool the&amp;nbsp;house with a&amp;nbsp;blower and&amp;nbsp;radiator.  A&amp;nbsp;water pump is&amp;nbsp;significantly cheaper to&amp;nbsp;run than an&amp;nbsp;air conditioning compressor.  More expensive than the&amp;nbsp;air version above, but&amp;nbsp;may be&amp;nbsp;able to&amp;nbsp;provide greater cooling capacity.&lt;/div>&lt;br />
