Hi; I'm a retired environmental scientist who joined EcoVillage at Ithaca in '92 and am living in the first neighborhood. I'm interested in using the principals and practices of permaculture to reduce our consumption of natural resources. I'm tracking the neighborhood's total use of water, electricity and natural gas to see the extent to which this suburban ecovillage/cohousing community actually is moving towards sustainability. I'd like to explore using more alternative techniques such as rainwater collection instead of potable water to flush toilets, a strawbale composting greenhouse to grow salad vegetables in winter, solar energy for preheating hot water, geothermal energy for space heating and photovoltaics for electricity. I'd like to grow tree crops such as fast-growing poplars or bamboo for some useful purposes. Any suggestions? Jay Jacobson
