RE: [rp-ml] Slow growth

All

The website describing the work of Enrico Dini does indeed look to be
revolutionary and fit's Adrians suggestion of print anything from sand.

Must admit though I find the claims re Enrico's Binder to be A. Mysterious
and B. to feel like it fits in the too good to be true category. (I could
be being excessively cynical here, sorry).

I wonder why the Construction industry is'nt snapping up the binder for
it's Portland Cement beating properties alone.

There should also be a ready market for smaller machines to print out
Bespoke Architectural Stonework to order (Quoins, Keystone's, Arch's,
Gargoyles etc). At least in the short term as folk catch up with the
concept.

Re Adrian's question of what to do with all the energy.

Consider that the Dessert Lands arguably have some of the highest energy
concentrations in terms of Insolation.

They also have water (just not easily accessible on the surface) or abut a
Sea.

Harnessing that Acreage for energy capture (Adrian's Robots) and coupling
it with Desalination and Electrolysis of water could preposition the
Dessert Lands to continue as the global energy suppliers post Oil, through
being the primary source of Hydrogen for a global Hydrogen based economy.

Interestingly enough Hydrogen from Fossil fuels (with carbon capture) is
readily doable as a way to kick start the process.

Alternatively.

Take a jolly into the dessert by camel every once in a while to
hunt/harvest the surplus solar cells and sell them on to folk for
Domestic/Industrial Electricity production elsewhere.

I guess if you leave them too long in situ Sandstorm Abrasion and Burying
could be problematic.

Thoughts for what they are worth.
