It seems to me that testing basic physical characteristics should be
helpful for every usage category. The testing data should help
people determine which particular papercrete mix will work best for
whatever particular application they have in mind.
I'm proposing that we create a suite of tests that can be performed
on a wide variety of different mixes.
This testing program will probably be a never ending process. People
will always be coming up with new ideas. This will allow us to test
new mixes 5 or 10 years from now that we haven't even thought of
yet. We should be able to compare them to recipes that are tested
today.
I'd like to see us test everything from simple paper-mache to the
ultimate uber-mix that a techno-freak invents years from now and
everything in between.
This won't happen overnight, of course. It starts with one or two
simple tests. We will add each little bit of data we generate to the
recipe and testing database. Over time we will have a very powerful
dataset that will help us greatly. With a lot of us working together
we can cover a great deal of ground much faster than anyone, even a
professional laboratory, could cover alone. We'd be leveraging the
power of this wonderful group of people. All of us would benefit.
