2 sad bullying stories in the news this week in MA:
$35M lawsuit: Lynn failed to protect bullied kid
South Hadley: Prosecutors: 9 teens charged in Phoebe Prince death
To these communities and families and friends of all involved, my heart goes out to you.
ObComment: Many of our schools are broken. Bullying is a symptom of deeper problems. Not just with our schools, but with our communities, families, society. Schools are just a mirror. But still a good place to start!
Bode Miller: “The Olympics is definitely, in my mind, a two-sided coin,” he said. “It has all the best things of sport. It has amazing energy, enthusiasm, passion, inspiration. It’s what changes lives. In that sense, it’s the pinnacle of what sports and camaraderie and all that stuff is.
“On the flip side of that is the opposite, and that’s the corruption and the abuse and the money. I’m not pointing fingers, but that’s what was bothering me [in Turin 2006], and being thrust in the middle of that, and being the poster boy for that, when it’s the absolute thing I despise the most in the world was really draining on my inspiration, my level of passion. . . . I just had the plug pulled out on my most important fuel source, and it had been happening for a year, and it was just too much.”
“Alas if the space heating limit is 15 kWh per m2 per year you have only a few options to tweak. One of those is sub slab insulation.
Once you have maximized the cost benefit of wall insulation (which is the most expensive because it increases roof area and fastening costs) and the attic is full to 120 how else do you meet the heating? Well even though sub slab is not that effective it is an available option to meet that unyielding target.”

“… PH software assumes too low of a ground temperature versus what has been measured in cold climate housing with decent sub slab insulation.”
Joe Lstiburek of Building Science Corporation puts it this way:
“In order for the fan to work the air needs to come from the outside and not be pulled from the house so this means that the attic ceiling needs to be airtight. If the attic ceiling is airtight you don’t need the fan. Your money is better spent on something else.”
Did you know that the thermal efficiency of power plants is basically ~33%? This is for oil, coal, natural-gas. I had no idea it was THIS low. I find this horrifying. Our propane furnace at our last house was AFUE of ~94%. LINK
In other words, it does seem a little silly to heat with electricity (at least quite indirect!), even if you are using an air-source heat pump with a COP of over 3 like the Fujitsu 9RLQ. This is essentially just getting you back to 1.00 (.33 * 3 = 1) And minus the losses due to transmission I suppose.
I should look at those plug-in hybrid calculations again. I suppose the issue there is maybe that internal combustion engines kinda stink too, in comparison to electric motors, so it more than makes up for the hopeless electricity generation.
And of course, there is always PVs and GreenUp type options thru the grid. But still. Something seems a little fishy?

Easy, use less glass.”
