extrude
It takes 32amps over 40min for one square meter of sheet using the sheet press machine. An amp is 1kwh, 32kwx0.66= 21kwh. Clear plastic at R2/kg(directly from street recyclers), R12/sqrm + 21kwh x R2.60(eskom) = R12 + R55 = R67/sqrm. A solar Redrok solar links heliostat furnace brings the costs down. For a 10x30m(300m) surface area Greenhouse the costs are between R20,100(eskom) and R3600(Heliostat Mirrors, sun is for free) for the plastic covering. The energy required is 3.5kwh/kg or plastic, about 4sqrm of solar mirrors. A more practical machine for making sheeting using the sun, is the motor powered extrustion molding machine to extrude 7cm wide by 6mm thick planks of plastic timber and then manually heat weld the timber together for a required size using a plastic welding gun. It will be much easier to heat the single thermal element of the injection extruder. Compare the cost of everyting, bread, cars, metal in terms of sqr meter of sun and then ask yourself what you are doing stuck in traffic 7am on a Monday, on your way to office politics to get money to buy what you could have roped the sun in for instead? https://preciousplastic.com https://community.preciousplastic.com/academy/build/sheetpress sheet plastic <br https://www.youtube.com/watch?v=3-JFVo6BDA4 building extruder https://www.youtube.com/watch?v=avdOxtKywbk https://www.youtube.com/watch?v=YyfputUXCD0 The Process of pressing a plate from plastic waste granulate by means of a plastic plate press design by Mark Bachrach and The MMID Foundation http://mmidfoundation.org for more info see http://studiombb.nl and http://plaatjes-makers.nl
