Ann: Eden Applies for US Patent for EdenCrete, page-25

That is a good point.

It is quite possible that while edencrete used this method of mixing in nano-carbon tubes, the method will also work in the other forms of nano-carbon.

While eden may not be producing that product with those forms, it does block others from using that method of mixing for their products... a good blocking move.

The patient application appearing so late did worry me at first... after all, a leaky ship can have the method sold off to a competitor who can patient it pretty damn quick if the company was too slow... well played as it turns out.
