It is also worth noting that thermal mass, by itself, does not improve efficiency. Improved efficiency is often a side effect of adding thermal mass, but the improvement is really just a result of extracting more heat from the exhaust gases. This could be accomplished just as easily without adding any thermal mass. For example, I could extract more heat from my exhaust simply by using a longer piece of aluminum duct between the stove and fireplace (I have noted that the exhaust temperature drops about half way to ambient for every 20cm of tube length).
“In France, having children isn’t just dependent on the economic situation: ‘Many of the babies born in 2010 were conceived in 2009, during the economic crisis,’ underscores Pascale Breuil, head of INSEE’s Demographic Department. In France, fulfillment is primarily dependent on having a rewarding family and social life. Indeed, almost 60% of young French people want to start a family and raise children; this is the highest rate in Europe according to a study carried out in 2011 by the Foundation for Political Innovation…The family policy helps to explain this ‘French exception.’
So our stone work is at a dead standstill and we’re trying to find new guys. Originally we were paying $6 a sq/ft for labor, and we had found 3 masons to agree to that price before we went with Josh, then we gave him a bump to $, and then he left, we had guys quote us $15, or one guy quoted me $23. I wonder if he thought I was an idiot or couldn’t do math. I’m not a lottery winner, I’m an educated successful self made man, I can do math, I can read financial statements, and I even sometimes do for fun. So this one guy quoted us $23 a square foot and says he pays his guys $7 take home pay. Like I say, I’m not an idiot, I know by talking to masons, local and out of state, and reading articles from Masonry Magazine and trade publications, I know how much a mason can lay down in a day. It supposed to be between 100 and 200 sq/ft, per guy per day (with a tender, some lower base laborer guy fetching and carrying). Even Josh’s guys who were slow, according to Josh, did 50 sq/ft a day. So if I remember my third grade multiplication correctly that means this guy is paying his workers $350 to $1400 a day. With 260 work days a year at the low end these masons are making $91,000 a year, at the high end $364,000, per guy, per year. It was all I could do not to laugh in his face, I waited until after he left. We get these ridiculous “castle prices” sometimes, yet another thing to deal with.
