<p class="MsoNormal"><br>Group all, <br><br>Here's a article I wrote on the <a href="http://www.renewableenergyworld.com/" target="_blank">www.renewableenergyworld.com</a> website. Supposedly it's one of the biggest on the internet, but a good introduction and overview of biogas---no, I don't get extra money for everyone that visits the site. <br>

Just a reminder as we focus on the technical aspects of anaerobic digestion there's still a lot of outreach to do to make biogas more widely understood and adopted. <br><br>Warren Weisman<br>Owner, HESTIA Home Biogas<br>
