PIGFACE POINT TOUR PICTURES: Set 10.
Fresnel form of concentrator; if each piece of mirrorwas brought out so that its edge aligned with that of the neighbouring piece, you would have a parabola.
A mini-steam boiler and turbine goes at the focus.
Experimenting with solar distilling, and solar chimney energy device. Sun's heat warms water in shallow plastic tray. Heat goes up a 5 m chimney to turn a small windmill. The approximately 50 wqusre metre area will also add to rainwater catchment area.
Bee’s hive, and spare boxes etc. The hive keeps two households in honey, with perhaps five hours work a year. Bee keeping is an interesting hobby. Improves pollination of fruit trees. Provides wax for craft work.
This is the industrial area. Most of the manufacturing we will need in a much simpler economy can be carried out in very small premises within our neighbourhoods, mostly by family enterperises. The pottery (centre) is a good example. All our crockery should be made from local clay in a pottery like this … by people who love making pottery. The pottery shed is also made from local clay. To the right is a blacksmith's forge. A car fan top right blows air through the fire, and through the mnall furnace that is not far awaa, to melt metal for casting. At the back on the left is a shed for mosaics and concrete casting.
Home made pottery wheel.
Furnace for melting metal, e.g., metal to castr buckles, hinges, ornaments. Wood fired. Air blown through by 12 volt car fan. At the back is the kiln for the pottery.
The roof in the centre is over a horizontal shaft pot lathe. Leaning against the upright is a fibreglass mould for structurally strong concrete columns. There are about thirty in verandas and the tea house.
Most of the roofs, including small sheds collect rainwater for the house. The gutters have covers to keep leaves out; the water runs around the curve and drops into the gutter, while leaves drop off.
Cutter/shaper cut from tin, swings forward and back as the pot is rotated…about seven hours after a layer of cement is put on so it is not too hard to scrape. Might take two weeks to make one, doing a bit at a time. All the big ornamental garden pots around the house were made on this.
This is another cement lathe, with a vertical shaft. Cutter rotates around vertical shaft. New pot rim being made. The garden pot stem on the centre left was the last job just taken off.
Garden pot being made from cast sections. Circular parts will be put on using the vertical lathe.
