thermal mass is a passive way to stabilize temperatures. that's why a stone fireplace stays warm long after the fire has turned to embers. thermal mass is also why radiant floors are often under poured concrete floors, as the cement will slowly release the heat. this product called SCIPs has a foam or straw core encased in wire mesh with shotcrete sprayed on either side. so its an engineered version of a strawbale home. kind of neat.

i found one company that precasts all this stuff, csips, called Dukane
i don't know if this is pre-made or not Dow TMass: article

UPDATE: got an email from Dow that they don't make it anymore. found out SCIPs are better for warm climates. ICF is better for colder climates.

i like the concept of radiant heat floors. usually the heat comes from water circulating under the floor. but there's this neat thing called the air floor. it circulates warm air in the heating season and cool air in the cooling season.

UPDATE: similar product but closed loop, called Legalett

Why did Peter put his coat on before jumping in the water? John 21:7

-
I have the great pleasure of facilitating every week a Bible discussion group with several high school students. We've been discussing the Gospel of John  this past year, and we finally finished tonight. We enjoyed the humorous scene John writes about in this last chapter. The great apostle John can't help himself when it comes to embarrassing his fellow inner circle apostle; the denial of Christ, his slowness in getting to the empty tomb, and this event in the last chapter. John 21:7 That disciple whom Jesus loved therefore said to Peter, "It is the Lord!" When Simon Peter heard that it was the Lord, he put on his outer garment, for he was stripped for work, and threw himself into the sea. What's the joke? Well John is the first to realize that Jesus is on the beach, #humblebrag, but then Peter puts ON his coat before jumping out of the boat? I've seen some academic ink spilled trying to explain this weird behavior on the part of this fisherman ( good one

I bought a recumbent bike last month from Actionbent and have been using it for my commute. here is a picture of the Jet Stream 2, understeering. i've been a bicycle commuter for years but last summer i developed at work a bad case of tendinitis in both wrists which made riding painful. one day i longed for my old Huffy Star Spangler with the banana seat and the hot rod handle bars and pined for the good old days. then i remembe

The near sacrifice of Isaac and bad religion

Bad religion asks parents to sacrifice their children. Bad religion is cultural. Bad religion looks for scapegoats. Bad religion always find scapegoats in those with less power. Bad religion kills kids. Abraham's story in Genesis 22 is a story of good religion prevailing over bad. image source    Abraham lives in a culture which not only approves of child sacrifice, but even encourages it for assistance from the deities. Abraham believes his deity wants him to also perform this act of devotion. But after he ties his son up, he has an encounter with God unlike any previous one. It appears God changed his mind.  More likely, Abraham changed his mind about God. Evangelical and fundamentalist christians also live in cultures where they think their deity asks them to bind their children, to not let them live in truth their sexual identity. Hence, these children who normally benefit from the protective effects of religion on suicidal thoughts and tendencies actually experience it worse a
