Would it be a good or brilliant idea to use a stationary mounted gas engine to generate electricity through a generator and capture all its heat through running it through thermal Mass. For example have the water pump send coolant through a radiant floor in lieu of a radiator and have the...

I have pondered the idea of the total btu release from gasoline or propane being ignited by spark or burnt in flame. It seems to me to use an internal combustion engine to create both torque and heat would be superior to simply burning it. The torque energy could power alternators, generators...

I'm seeking general design guidelines. Basic specs 21 feet spans, 6" thick slab. Slab supported by 2" thick stay in place pavers for 2" cover for fire protection.

Thank you. What would your opinion be of sleeving the beam with L rebars in the slab, tensioning the slab so the vertical L s could move in, then grouting the sleeve after a while?

What's the current thinking on the detail of a post tensioned slab supported on all sides by spandrel beams. The beams can be considered as a top bond beam of five inch width cast in place within a wall cavity. Will the shortening of the slab cause adverse effect to the beam? Should one let...

PVA fiber or helix steel fiber could be added to the panel mix. I've used with approval Helix fiber as a substantial rebar replacement in the cast in place, at 13 pounds per cubic yard.

I'm hoping to finalize a design for a precast pea gravel concrete wall panel to serve as a stay in place form for cast in place concrete. It will be a non braced system to hopefully contain form pressure of 1500 psf at the bottom of a ten foot pour. My concern is that the embedded expanded...

I'm using 2 x 12 boards cut with a table saw at a 20 degree bevel so I can decrease the interior thickness of pavers from two inches to 3/4" in order to benefit from less material and lighter weight. The 1-1/2" thickness is pressed 1-1/4" into the concrete. I seal the cut boards with two coats...
