: Just note that running this does cause your computer to use a lot more power. On board my laptop draws ~2A @12V when just running, but draws close to 8A when running BOINC. The fan runs faster in my tower Windows box. The box gets warmer, but not alarmingly so...thanks. I was a SETI supporter a long time ago, but my systems were so slow it just trashed them so I had to drop out. |

EXACTLY which spyware are you referring to? Nothing has been installed onto my system except the heavy-loading computational system. It uses 21.4MB of hard drive space for data storage but empties it when it goes into the report cycle. Looking at the file, there's nothing about me in it at all and it's not encrypted, unless you consider physics and chemistry cryptography in your world. I'm running it wide open on a couple of dual core Intel machines and there's plenty of CPU left to watch Livestation streaming, type this nonsense to you and download more movies from alt.binaries.movies.divx to play on my Nokia Linux tablets. It also doesn't upset my movie viewing on the same machines. It only uses internet bandwidth about once ever 28 hours of number crunching to get the next job from the server and to upload the report of the last job, about 30 seconds, tops. The current job has been running full bore for 26 hours and has about an hour and a half left before it uploads its findings and starts the job it got this afternoon. If you know of any spyware, I'd be happy to investigate it..... GOOD GRIEF! "Love Cypress" commercial just came across Euronews and after seeing the thong-clad model walking through the Mediterranean white sand beach, I'M READY TO GO!.....How DOES she keep from falling over on her face?? It defies Physics! You'll actually find out that this is based upon the BOINC platform, which supports many different distributed computing projects. It actually grew out of the SETI (Search for ExtraTerrestrial Intelligence) project which was started in the mid-90s, which was when I started using it. You can find info on BOINC at http://boinc.berkeley.edu/ There are currently 319,060 active contributors running this on 567,770 computers producing 1,441 Terraflops per hour! I personally have contributed almost 27,000 hours of computing time, which places me at the 96% percentile of BOINC contributors and 94% in the US. http://boincstats.com/stats/boinc_us...de39e8f890005a 30e5de9dfd848a929 Just note that running this does cause your computer to use a lot more power.

My panels are fixed horizontally, but I figure that costs less than half the potential with no effort. In fact, near noon on the summer solstice a horizontal panel collects roughly 90% of the available energy, and the Sun only has to be up 30 degrees to make panels 50% effective. My plan for the future (which seems to be perpetually delayed) is to add large adjustable panels on my davits which would double my generation, even more if I adjust frequently. ** Posted from http://www.teranews.com ** Admittedly I am in the "bright sun" zone but nearly all the cruising boats I see have solar panel arrays. Usually 3 to 4 panels, and usually mounted horizontally with no regard to the direction of the sun. the main worry seems to mount them in such a manner that shadows do not fall across them. Several people have told me that they normally use no other source of power. Regarding regulators you only need one if the panels can get your battery voltage above 13.4 volts. If you panels are old or undersize (like mine) you don't need the regulator at all. Cheers, Bruce (bruceinbangkokatgmaildotcom) |

Just like everything else about your boat they are old, tired and stuck in place. Wilbur Hubbard |
