Depends on your point of view. Do you (generic, I'm not specifically asking chalsall) think that its contribution to GIMPS, along with any other purpose it may be fulfilling, outweighs its contribution to carbon emissions and your electric bill?

With one exception that xilman is fond of pointing out. They make excellent space heaters. In the winter, operating an old machine for GIMPS is essentially free if your house needs warming. I know this is not a consideration in Barbados

but is in other colder places.

I think that falls vaguely under this category:

Who says the purpose can't be "space heater".

Now that's an angle I hadn't thought of...

I apologize for not having phrased my posting more carefully. I didn't mean to accuse you of anything. I was just presenting a set of alternatives, without intending to actually attribute any to you.

If you can't contribute to GIMPS efficiently (read: as a side effect of other uses of energy), then perhaps you shouldn't be doing so (from a global energy / carbon emission POV).

I contribute to GIMPS as one of my primary, not secondary, activities -- so that doesn't apply. :)

The waste heat is a noticeable contributor to heating my apartment about half the year, reducing my use of fossil-fuel for heating. My electricity for air conditioning (and for the system producing the waste heat) is 100% from renewable sources. Also, my doctor recommends using A/C rather than open windows: unfiltered outside air would trigger my allergies on the vast majority of days (I've actually tested that -- lots of flowering plants around here), which would make me miserable. I've had the allergy shots to reduce my sensitivity as much as current medicine can.

No apology needed. And I hope that I have not caused any offence, to anyone. I believe that debate is healthy.

Sometimes we even learn something (as I have here)....

I sincerely hope this thread doesn't start another GLOBAL WARMING: HOAX OR REAL!?!! debate...

monst helped himself to my 192M range so I am taking 80.5 to 80.6. Hope that is ok with the crowd here.

Fine by me, too.

I'll start moving into 80.7M in a few days, if that's ok with everyone.
