The two compounds in these long acting photoluminescent
pigments are strontium and europium. They are not radioactive and are cousins to the luminescent zinc oxide of our youth. These are much brighter and longer lived then the zinc compounds. ![]() examples of products using these compounds. Move your mouse over the photos in the link below http://www.ez-bright.co.jp/en/products/products.html Any source of heat will make steam. That engine will run on government paperwork! My train of thought would be to use biogas (methane) generated from decomposing organic matter. True sustainable permaculture in action. This would be best done at a community level rather than an individual level. Think city sewage plant. The methane is there waiting to be utilized. On a farm using the already available manure/humanure which must be disposed of anyway, is also highly viable. The process produces fuel for heating and highly valuable compost for crops. It is also independent of centralized control Refrigeration. An already perfected technology exists using ammonia as the refrigerant. Any heat source; kerosene, propane, natural gas, biogas, heats the ammonia and starts the cooling cycle. There are no moving parts! http://home.howstuffworks.com/refrigerator5.htm I have lusted for a propane refrigerator like this one made by the Amish http://www.propanerefrigerator.com/ but they are not mass produced, and are therefore very expensive (2-3000 dollars). Their consumption of propane/kerosene is also fairly dear. The second issue could be circumvented by using one configured for natural gas and piping home made biogas into it. Voila! Sustainable refrigeration that will last as long as your livestock produce manure! Once again, this technology would best be implemented at a community level. Aspects of the technology are time intensive - you don't fire up a steam engine and just walk away and leave it. It needs watching and tending. In a radiant zone community this would be one of the many regular chores to be done to make a community work. Last edited by Baggywrinkle; 09-27-2008 at 04:23 PM. |
