How about a sub category for scrap D.I.Y, ways to use all those things that would normally endup at the local tip
My topic here (http://www.overunity.com/index.php/topic,3007.0.html) is just one idea, so if you have any ideas about how to use that milk carton your about to throw away, then post it in the new sub category or if it's not possible to create a new category then post them here, if it is the latter I will change the thread title to something more appropriate.
hi there
10 years ago i went to germany where i visited a factory that one freind of mine has there and what they do with milk cartons is that they shred them to peices >>> as most of them are composed of paper carton , aluminium lining and plastic inner air tight sealent >>> they wash the shreds then they process with a big hydrolic press and a hot bed they make a very high quality copressed top board. as the hot bed heats up the plastic melts creating a though cement >>>the paper and alu act as strength fiber under the extreme pressure. the result has many high qualities surpassing by far wood top board: namely >>> very water resistant >>> higher durability >>> high strength to name a few
applications >>> home/office furniture >>> car lightweight inner amenities (dashboard roof fittings and so on )
Very interesting recycling process, sounds like it needs a lot of energy though.
Some more ideas for those into electrolysis, I purchased a car battery charger that is also suitable for lead acid gel batteries, only cost me 3 pound sterling from the local market, what makes this useful is the 100/120HZ pulsed DC output, mine has switches for high and low plus 6 volts or 12 volt output.
The 100/120HZ is derived from the 50/60 hz passing through a full wave bridge rectifier.
The high low switch is used to limit current on mine, on high it is maximum current 8 amps, on low it is around 3.5 amps.
The transformer in mine is rated at 10 amps, so with a little tweaking I'm sure I can get 10 amps out.
