Hi Jeffe,
Many of us have read your articles about your turbine and its not so good performance. What did you replace it with and how much better is the new model doing? Regards Michael Lawley Renewable Energy Engineer EcoInnovation 671 Kent Road R.D.1 New Plymouth New Zealand Phone: (NZ) 06 752 2765 Web site: www.ecoinn.co.nz email: [EMAIL PROTECTED] ----- Original Message ----- From: Jeffe & Carrie Aronson To: [EMAIL PROTECTED] Sent: Sunday, November 14, 2004 10:47 PM Subject: [microhydro] New post: Low Head Platypus turbine for sale: Victoria Australia I've just installed a new low head turbine and am selling the old one. It has a Smart Drive generator on it, and makes 200 to 350 watts with a 5 to 6 foot head. Smart drive is in perfect condition, turbine needs some work.
