>From MIT: http://laptop.media.mit.edu/ Sub-$100 laptop design unveiled http://news.bbc.co.uk/2/hi/technology/4292854.stm -Mark Nagel Everett, WA ===================== From: Max Klohn <[EMAIL PROTECTED]> Date: Sat Oct 01 07:07:32 CDT 2005 To: [email protected] Subject: Re: [microhydro] microhydro powered Internet Cafe Dear Ron, While not having a formal Internet Cafe, we live in an isolated outpost with a satellite link, so we frequently operate like such. We have a battery charger (pelton runner and delco remy alternator, trojan T105s and a 900 W sine-wave inverter). Power generation is 550 W (daily 13.2 KWh), with that we run two houses with energy-efficient lighting, the usual fridges and washing machines (the latter ones within time slots), small tools, plus the telecom gear, a local wireless network and a couple of laptops. IMHO the main caveats with this kind of setup would be: * If power is limited, use laptops, desktop computers tend to suck a great deal more power. * If power comes from an inverter, be sure it is a true sine-wave one. "quasi-sinusoidal" and chopped waves tend to overheat power supplies and cause them to fail prematurely.? In another subject I am interested in your bronze runners: pricing, sizes, features (monobloc, soldered, bolted, polished etc) for several small projects in southern Chile. Could you please send me some more information? Greetings, Max Klohn Le mercredi 28 septembre 2005 ? 09:50 -0700, davis ron a ?crit : >?? Dear Group, > >???
