Will You Drink Crap Water?

Sewerage is just a load of crap. If you think this you are on the wrong track. It can be a valuable commodity. The cleaning process begins with a giant comb that lets the good stuff through and blocks the solids - tampons, tennis balls, toys, sneakers, marbles, cardboard and so on are discarded.
fine polymer membranes filter sewerage
The second stage involves very fine polymer membranes. The membrane pores are less than a millionth of a millimeter thick which filters out microscopic contaminants. That is all there is to it, just fine filters
raw sewerage
Purified sewerage is used to water crops and is pumped into the mains water supply for drinking by the public. It is claimed that it is better than bottled water from mineral springs. This of course is a bold-faced lie. It still contains some ultra-fine remnants of crap!

Polymer Notes are a Loss

The invention of the polymer banknote was a disaster for Australia. Costs involved in continually replacing them is enormous. Let's face it paper and cloth are quite substantial materials. They can stand up to a lot of wear and tear. The main problem with polymer is that once folded it cannot be straightened out - a permanent crease prevents stacking of notes by banks and neat storage in consumers' wallets.

All ATMs give brand new notes. It is impossible to do otherwise because they need to be tightly stacked. You would be wasting your time just trying to put used fifty dollar bills into an ATM.  Replenishing ATMs is a major cost in the modern age.  Government should be looking to save costs here.

Considering the saving from fewer forgeries is a pitiful A$50 million, the extra cost is not worth it. Anyway, if people get a forgery they always pass it on, as giving it to a bank results in nothing in return.  Government should take the loss for forgeries.  Then people would hand them in.

The issue of durability is still a big government lie. As noted above they do not last longer: they become unusable after first use and fold. It is amazing how government blindly accepts a new idea for the sake of it when it is a big expensive white elephant.
