there has gotta be a 12 step program for this. Mark...do you have anything to say about this?? Back to crunchin' SETI after a month of doing other projects, and with me it is an obsession. Why else would I have 4 OCed quaddies heating up the basement? Clk2HlpSetiCty:::PayIt4ward

I did some tinkering with the cmos of my um generic quad last night (hobby). Just a slight improvement from 2.4GHz to 2.784GHz, but I'm hoping to see a change in my stats. I've been trawling through BoincStats this morning (again, hobby). Can anyone tell me what a CHRPsIBM,0200-150Cell Broadband Engine is please? It heads the list of average credit per CPU second.

"Yes, #1 son, you really do need a quad" :) Still a hobby, just a little compulsive at times, lol. Happy birthday Calm Chaos!!! Terrible twos? Calm Chaos... are you feeling it yet? |

Oh, I would say that I surely fit in with the 'obsessive' group...LOL. 4 quaddies and 4 duos....all being fsb whipped....dunno if I am gonna be able to withstand the electric bills when I have to start the air conditioning up as the seasons change....ouch.

I think it's an IBM Blade server of some sort. The PS3s have a different ID. -Dave

Well the apartment is in total disaray. Nothing is in the same place it was 24 hours ago. I just needed a 5ft section of cat 5 to hookup an old pc. After almost 40 years of collecting electronics hardware and junk, I was sure there was one somewhere. I found an old crystal radio I made in the early 60s. I found an old heathkit electronics lab from the mid 70s. I found an old CoCo computer from the 80s.(hmmm another cruncher) I dug under my very first IBM AT. I looked in, around and under more old systems.(still don't know why I keep them) Looked in every container, box and drawer. By the time I realized it was hopeless the stores were all closed. Now I ache all over and used language I thought I"d forgotten when I retired from the Navy.(sorry kitty) But the refreshing of all those old memories was priceless! I used to be a cruncher like you, then I took an arrow to the knee. |

You might find that you can buy some panels and an inverter that are not covered under the California PV program for less money -- especially if the inverter is not a grid-tie inverter. You won't get reimbursement from the state, but the savings will probably be more than you would have received in rebates. Your "farm" is a nice predictable draw, so you can work with that load and see if you can take most or all of it off grid.... |

Hobby or Obsession.... Hmm....have a Dual Core and a Single core crunching right now. Smoked a single core laptop that I used as well. Almost ready to upgrade my Single Core gaming machine to a Dual Core. Also planning on buying a duo-core laptop eventually. Wife has a Single Core downstairs she won't let me touch. I was also going to do volunteer work at a Fire Department so I could get their 4 dual cores on Boinc but it's not wheelchair accessible (go figure). Yeah it's an obsession. |

I think you misunderstood my statement. Grid Tie costs more because the inverter must be able to safely "sniff" the grid and turn off if the grid goes down. If it doesn't, and the utility is doing maintenance and shuts down part of the grid, your inverter could kill a utility worker. Grid Tie inverters have to be very safe. They have to be approved by the utility. If on the other hand, you toss a couple of panels on the roof, use it to charge some batteries and use them to feed a PC, you have a known, constant load (lets say 60w for a fairly efficient machine) and three 160w panels and some decent batteries will take that one computer off-grid. You don't need an inverter, you can buy 12v, 24v and 48v ATX power supplies. It's also more efficient if you convert once instead of twice. ... and no approval from the utility because you never touch the utility. The cost of taking one computer off grid depends on what kind of deal you can find on panels, and batteries. So, we're not talking about taking your whole place off grid, but looking at a few strategic loads. It's worth investigating, however you end up doing it. |

Do you have generators on the farm to cover grid outages? I'm looking at a weekender on 2.5 acres up country this week. It's currently off grid (or not supplied with grid current ... lol), but does have phone connected. I'm investigating solar and wind as supplimental power sources to the two generators they currently(now) use. AndrewM |

I didn't suggest that you needed to get off the grid. You want to reduce your electric bill. One way to do that is to go grid-tie, spin the meter backwards during the day, and then draw power when it is dark. The other way is to simply unplug as many loads as possible. Taking your whole house off-grid may not be as simple as it sounds because loads are very dynamic -- lights, heat, A/C, refrigeration, they vary alot. Computers don't. Computers running BOINC 24/7 are a very predictable load, and that makes it easy to design a very simple (cost effective) system to take that constant, predictable load. Servers here draw a near-constant 500 watts, or 12 kwh/day. Currently, we're paying $0.18/kwh. Just taking the server load offline would cut our electric bill in half. ... and I can do that using less expensive gear and no need to get approval from the utility. I would need to make my battery bank about four times larger. It's four group 24 batteries now, good for about 9 hours, and I'd need to supplement on cloudy/rainy days. |

Your TV is a good example of a load that I wouldn't try to take off of your meter. 4 hours of TV is one kilowatt-hour. 24 hours on a 60w PC is 1.5 kilowatt-hours. You might watch an hour of TV one day, and 12 hours of TV on another, but the PC is on (crunching SETI) so it is incredibly predictable, and easy to size the components. Batteries to take the load would cost about $1000. A 2500w grid-tie inverter is near $2000. Panels are about the same either way. Your contractor may not want to look at that because he makes more on a grid-tie system. |

$0.18 per KWh, could You please can up a few hundred of these and send them this way :) Day Price here is $0.35 KWh.
How are You producing Your power going into this battery bank? Windmill, Solar Panels? Just curious :) ChrisD |

After almost 40 years of collecting electronics hardware and junk, I was sure there was one somewhere. Did you ever think of moving to some hick town and opening a museum? Somewhere with a bit of room to dust off the old computers and fire them up. I bet kitty had fun invstigating, too. Lol AndrewM |

That's averaged -- we pay anywhere from about $0.13 to $0.35 depending on total usage during the month, based on a 10.3KWh/day baseline. ... but when you take the total bill divided by the number of KWh, it averages about $0.18.
I'm not producing any power locally (unless the mains go down) currently. I've spent a fair amount of time looking at options.... |

One or two machines crunching on idle: casual user. So what does it mean if you give everyone you can free computer help so you can install boinc as a service on thier computers?

California's electricity deregulation is probably a textbook example of how not to deregulate. If we could stay under 300 KWh (mild climate, it's possible) we'd pay 2.8 cents for generation, and 7.2 cents for transmission and delivery. As use increases, it goes from 2 cents to 5 cents, then 16 cents, etc. and when you pass 300% of baseline, it's 29 cents/kwh for generation, and the same 7.2 cents for delivery. The rate increase that didn't happen would have raised the top rate to 42 cents. Same structure applies to JokerCPoC, but where he lives it is quite a bit warmer, so his baseline allocation (that first 300 KWh/month) is probably much higher than ours. For most of us, the goal to solar, wind, etc. is just to get out of the top tiers in the rate structure. |
