It&#39;s extremely difficult to create a structure in which the tenets of custodianship, rather than ownership, are the foundation point for dealing with entities such as local councils and developers who simply wish to milk the land for everything possible.<br /><br />I&#39;m currently planning some informal sessions to bring the foundation concepts of Caring Economics and Partnership models (as contained in the works of Riane Eisler, as well as in the work of many &#39;new&#39; economists etc) to the Byron shire area in an effort to get real dialogue for transformation happening. I love this line: &quot;Any human activity needs to be seen as carried out under an implicit ecological lease covenant from the Earth, which expires with our personal, collective or corporate life.&quot; That, and the Earth Trust concept, are ones that I will be bringing to our community meeting for discussion and incorporation into our foundational ideology. :)Rimfirehttp://www.blogger.com/profile/06973880563591560946noreply@blogger.comtag:blogger.com,1999:blog-5849778833367156622.post-3760440258650210782009-12-10T18:59:21.974-08:002009-12-10T18:59:21.974-08:00Great post. I am interested in learning more about the development and application of ecological economics. Perhaps if they taught this when I took economics in college I would have been more interested! wikipedia offers some more info: http://en.wikipedia.org/wiki/Ecological_economics. <br />Can you tell us about the guy who inspired you to write these posts?<br />THANKS!jessi love.http://www.blogger.com/profile/05528759385993854375noreply@blogger.comtag:blogger.com,1999:blog-5849778833367156622.post-3621635244416963682009-07-20T15:45:14.367-07:002009-07-20T15:45:14.367-07:00I love how solution-oriented this is!

Yes, more people are becoming aware of the environment and making lifestyle changes that would dramatically affect the environment in a positive way. We in http://climatarians.org need to use all modes of communication to get the message across.<br /><br />Let’s make the transition!<br />Joost HoogstrateJoost Hoogstratehttp://www.blogger.com/profile/08663653677065799014noreply@blogger.comtag:blogger.com,1999:blog-5849778833367156622.post-63546882797111986882009-05-30T12:47:35.018-07:002009-05-30T12:47:35.018-07:00Nice slideshow!

We are convinced that the simple steam engine is the superior choice in CHP for plants under 500 hp in size, as well as solar concentrator power systems. We welcome any critique - <BR/>see <BR/><BR/>http://openfarmtech.org/index.php?title=Solar_Power_Generatormarcin_osehttp://www.blogger.com/profile/05052032028273550909noreply@blogger.comtag:blogger.com,1999:blog-5849778833367156622.post-67758951834809293412009-02-08T15:17:00.000-08:002009-02-08T15:17:00.000-08:00Please view our documentation as to why - from the open source perspective - Stirling engines are a bad idea, apparently inferior to simple steam engines:<BR/><BR/>The second and last cycle that was reviewed is the Stirling cycle. This cycle much more closely approximates the ideal carnot cycle. Mainly this is due to the use of a gas as the working medium and thus reducing the non isentropic loses associated with the condensation portion of the ranking cycle. Additionally the closed cycle use of air as a working medium eliminates both the complex valve arrangement of the steam engine and the inherent dangers of steam. Despite the ideal safety and theoretical thermal properties of this engine its cult of hobbyists and developers have yet to succeed in a low cost entry-level sterling engine. To achieve high efficiencies and a modest size it is required to pressurize the cylinders and preferably with an ideal gas. This greatly adds in complexity and cost. Furthermore to obtain the inherent thermal advantages of this engine a high performing regenerator is needed. This device acts as a heat exchanger to store energy during the expansion stroke and keep from rejecting it to the low temperature discharge side. In practice it has proved difficult to make a compact efficient regenerator and few stirling engines achieve &gt;60% of carnot efficiencies. These problems though are mainly due to pursuing a compact highly efficient stirling engine for mobile applications, one alternative is to look at slow speed large cylinder low pressure devices. This approach was tried in the S5. This engine was designed for burning agricultural wastes and is 20% efficient at transforming applied heat to electricity. The engine could presumably be retrofitted to accept solar input, however the initial construction and subsequent maintenance are reported to be fairly difficult. Most concerning to us at OSE is the very large cylinder, which is a result of using low pressurized air as the working medium. Manufacturing and machining of this cylinder will not be friendly to relative novices. Therefore this engine with the advantage of using a safe working medium (air) and the ability to accept a high input temperature, should be reviewed further when our machining capabilities are more mature.<BR/><BR/>We welcome feedback on this.

To compensate they often work with a pressurized gas. Then their is the task of designing an efficient regenerator. All of this puts the machining capabilities well out of reach of your open source participant.<BR/><BR/>Of course I am quite biased as I am working on the solar/biomass steam engine project over at openfarmtech.org Either way its really exciting to see the open source sustainable tech idea pick up steam!kabirhttp://www.blogger.com/profile/12517669370625553926noreply@blogger.comtag:blogger.com,1999:blog-5849778833367156622.post-37543169241843125412009-02-04T08:28:00.000-08:002009-02-04T08:28:00.000-08:00do you mean the best examples of natural buildings out there? <BR/><BR/>Sun Ray Kelly has some amazing timber frame cob buildings, there are great strawbales all over the country, Ianto Evans makes amazing cob cottages, and there are a myriad of examples around....<BR/>hope that helpsGreghttp://www.blogger.com/profile/16346725307961401013noreply@blogger.comtag:blogger.com,1999:blog-5849778833367156622.post-73261382619821210322009-02-02T13:03:00.000-08:002009-02-02T13:03:00.000-08:00doing a project on natural buildings, do you have any suggestions on some of the best ones? its at industrialecology.blogspotalexbhttp://www.blogger.com/profile/12793331039571112940noreply@blogger.comtag:blogger.com,1999:blog-5849778833367156622.post-26960282134063485662009-01-11T10:42:00.000-08:002009-01-11T10:42:00.000-08:00wow front page of the Wall Street Journal. not bad...<BR/>Perhaps you could take a picture of the front page for us?jessi love.http://www.blogger.com/profile/05528759385993854375noreply@blogger.comtag:blogger.com,1999:blog-5849778833367156622.post-46267993267568348162009-01-05T04:06:00.000-08:002009-01-05T04:06:00.000-08:00Dragonfly,<BR/>I just took a second to change the font...let me know if that works better.<BR/><BR/>Thanks for letting me know what works!<BR/><BR/>GregGreghttp://www.blogger.com/profile/16346725307961401013noreply@blogger.com
