Solar Tanks

The two models of octogonal tanks shown here represent a good example of what could be done for cheap with three 96"x48"x 3 1/2" foam panels, strapping tape, polyurethane glue, two cardboard gigs and a hot wire saw. The high column has a capacity of about 1500 litres (400 US gal or 1.5 metric ton) and the bigger tank can hold even more liquid. The tanks should be strapped all around at least every 6 inch or less to make sure the panels wont collapse under the weight of liquid. The joints should be sanded before glueing them together to get rid of the polystyrene hairs and chunks produced during the hot wire cut procedure. And yet, of course you can build bigger tanks from 108" foam panels. These tanks are purely fictive not tested before devices and and should be rated " try at your own risk stuff ".

Nice animation! Good idea too. Have you tried cutting the foam on a tablesaw using a fine cutting blade?

Thanks,

No I didn't. but it could be a good idea if you are confident with the accuracy. For my part I always use a piano wire and an old car battery charger to make precision cuts in Styrofoam along with Formica guides.
