REPLY Jim, my reply was directed to the question of "why not run a laptop directly from ships 12V power"? Evidently the person had declined to consider the dedicated power bricks which all laptop manufacturers do offer or else there was some other reason that was not stated. For example peripheral equipment like printers, fax, copiers, and scanners etc. can also use a lot of power. I picked 500 watts simply because it is one size I know is being made by more than one manufacturer. In addition, 500 watts is about what you would need to run a satellite TV plus DVD /CD player and home entertainment system. More and more liveaboards now have boats equipped like a floating condo and you find fewer and fewer minimalist who eschew the trappings of urban livigng. The fact is you can now find pure sinewave inverters in quite small wattages. Several less than 500Wats. I just did not want to be accused of being partisan to one specific brand. It is also a fact that not all computer manufacturers do make the effort to ensure their power bricks do not emit any RF interference. Because the Europeans have stricter regulations on the books, North America is often the dumping grounds for substandard equipment they cannot sell over in Europe. The nature of the question would certainly indicate a lack of technical sophistication such as you have,. In a technically perfect boat, none of my equipment would run at less than 90% efficiency and none o fit would radiate RFI and none of it would run hot. And if that was a technical possibility I can promise you it would be the only 30 foot boat in the world that cost a million dollars. Anyone with your technical know how and ability can certainly device much better solutions. but for th eaverage person who has to rely on of the shelf solutions, the choices are more limited. cheers Arild _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://www.liveaboardnow.org/mailman/listinfo/liveaboard To subscribe send an email to [EMAIL PROTECTED] To unsubscribe send an email to [EMAIL PROTECTED] The archives are at http://www.liveaboardnow.org/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
