Radiant Tubing Into Concrete Slab Detail
2008-08-01 03:22:00 This post is an answer to a question a reader asked the other day. "How should I treat the radiant tubing into concrete slab detail?"It just so happens that I installed the radiant tubing in our new home so I've got a bit of experience with this detail. Installing radiant tubing in a concrete slab is fairly straight forward. The key is to lay out the loops so that each loop is approximately the same length. Each loops starts and ends at the same point (location of the header manifold).The easiest way I know how to deal with the location where the radiant tubing exits the concrete slab is shown in this photo. I used a 1 1/2" electrical conduit 90 degree sweeps for each pair of radiant tubing. The conduit sweeps help make sure you don't have a kind in the radiant tubing where it exits the concrete.To support the conduit sweeps and radiant tubing during the concrete pour I pounded two wood stakes into the sub-grade on either end of the sweeps. Then I screwed a scrap piece of wood bet...

Casual Friday ? Ulysses at mission?s end
2008-06-06 14:35:00 It's always sad to see an old friend fade away, even when that friend is a robot. Such is the case for the international (but largely ESA-driven) Ulysses mission to study the Sun. Launched in 1990, the spacecraft has been powered by RTGs (radioisotope thermoelectric generators), and they are now generating so little power that the spacecraft is slowly freezing to death. Here's a video from happier times -- a 15th anniversary commemoration put out by NASA in 2005...
