Re: Biodiesel/emergy

[Perry Clutts]

Fryer to the Fuel tank IS great! I hope to use recycled restaurant oil for our composing facility (Tractor).. this season? Never seems to be enough time for some projects.   Seems I remember a section about efficiency of oil plants. Soy is one of the lowest, but still gets the attention here because we have so much soy that no one wants... especially the round-up ready (GMO) type... I guess what we need to watch and be aware of is how much energy does it take to produce these fuels. Anyone familiar with emergy? If all goes as well, we'll have an emergy analysis of this farm next year. Should be fun...   Emergy: (spelled with an "m")—all the available energy that was used in the work of making a product and expressed in units of one type of energy. [When you have your transformities worked out so that you know how much one kind of energy is worth in terms of every other, you can sum up in terms of one type of energy all the available energies used directly or indirectly to create something or to offer a service. That total is the emergy.]   So.. How much energy did it take to produce the energy that is being used for a given task!!   Think what a good emergy scores algae would have!!! Closer to the sun energy force!!!!   Perry   The best book I know of on this subject is from The Fryer To The Fuel Tank by Joshua Tickle. The most efficient producer of oil that could be used as biodiesel is actually Algae. It takes the Suns energy directly and converts it to oil (in the process eating carbon dioxide) and it could easily supply the worlds energy needs. As many other things could...
