Making something from nothing, use of readily available resources and cleaver optimisation techniques are key lessons from nature. Investro is a new Australian company with a compelling application that fits well with the emerging  “CleanWeb” category:
Rocksolver software uses advanced optimisation algorithms to fit irregular virtual objects together to build stable virtual structures. It is the first of its kind. Unprocessed rock is only 10% of the price of competing products. Rocksolver will enable the use of a very cheap, local resource by reducing the cost of labour. The production of unprocessed rock results in only 10% of the greenhouse gas emissions compared to competing products like brick, concrete and dimension stone.
