Photocopying

In spite of auto-double-siding machines being available, thereby "halving" the cost of copying, most routine copying is still done on one side of the paper only for speed and convenience.

Nevertheless routine copying using coin-fed single-side machines eats up a big chunk of most tertiary students' out-of-pocket expenses.

As paper-cost is a large part of photocopying charges, any reduction in the cost of paper - if passed on fairly - would help students and others everywhere.

So, in my dream, I bring together paper-suppliers, advertising agencies, and owners of coin-fed machines, to supply virtually free paper for copying machines.

Yes, shock, horror, the paper supplied has paid-for advertisements on the hitherto unused BACK of that paper, pre-printed with non-strike-through ink, and ranging from discreet watermark logos to fast-food ads, according to circumstancesa and discount-rate.

[I could go on at great length about the permutations and combinations possible in developing the idea, and about the negatives I can think of, but I won't need to!]
