"Vídeos ▼ https://vimeo.com/pannirbr ► RELATORIOS GESTAO ENCONOMICA Geoff Moxham - Biochar Lecture - 90min https://vimeo.com/ This is the final full lecture given by Geoff before his fatal accident in August 2009 and the public release of this video is intended as a second anniversary remembrance tribute for 27/8/2011. It was part of the ongoing workshops held at The Castle on the Hill in Uki near Mt Warning http://www.castleonhill.com/workshops.htm/ You can explore all Geoff's work on his website http://www.bodgershovel.com/ including a collection of videos demonstrating various pyrolysis and Biochar production techniques. This extended 90 minute talk shows Geoff in great form, complete with a supportive slide presentation, pyrolysis gadgets, him munching on Biochar samples, pyromania and his usual, unique Mad Scientist sense of humour. It's easy to see his skill as a qualified Industrial Arts teacher showing through and his early fascination with Professor Julius Sumner Miller on the TV show 'Why Is It So?', which he watched religiously in the early 60's. http://www.youtube.com/watch?v=LIfxV7uNZXQ It is also beautiful to watch his sense of fluid movement as he describes his concepts with his whole body and energy field. As a Tai Chi master you can see many of the Tai Chi set moves incorporated into his presentation. Geoff was the second speaker at The Castle that day along with John Davis from The Rainbow Power Company in Nimbin who gave an overview of solar power. This Vimeo video copy is Part Two of a DVD filmed and produce by Paul Tait from Gaia Films in Nimbin who has kindly given permission to upload Geoff's part of the lecture in full and make it publicly available at no charge. The full DVD, including the talk on solar power, is still available from Paul Tait gaiafilm@linearg.com for a very nominal price. You can find out all about the Biochar movement now from the primary person who continued Geoff's work by exploring Paul Taylor's website http://w

"stract This review summarizes the effect of high- and low-temperature thermal pretreatment (TPT) on sludge dewaterability, anaerobic digestion (AD), and biogas production efficiencies. The AD of the TPT sludge has demonstrated the following observations: reduced sludge retention time, increased biogas generation, higher organics degradation, improved dewaterability, and lower digester volume than the conventional AD of sludge. Energy balance of the TPT process was energetically self-sustainable and produced surplus energy at solids concentration greater than 3%. Net energy and energy ratio of TPT and AD revealed that net energy and energy ratio are increased with increase in total solids concentration"
