Another technology which has seen a lot of use in areas that have no electricity available is the Hydraulic Ram Pump. This is a passive device that just needs "falling water" of some form. It uses the principle of the "water hammer" to drive water higher than the source. You can't use one to pump water from a well, but if there is a stream or river nearby, you can use it to great effect. I believe they were used quite a bit in gold mining operations out in California. -- Ken Norton ken@xxxxxxxxxxx http://www.zone-10.com -- _________________________________________________________________ Options: http://lists.thomasclausen.net/mailman/listinfo/olympus Archives: http://lists.thomasclausen.net/mailman/private/olympus/ Themed Olympus Photo Exhibition: http://www.tope.nl/ |
