We can use the sun and desert to print (http://www.markuskayser.com/work/solarsinter/)
photo bio reactors

that process waste water and then use focused solar
to release the energy stored from the algae cultured as a result of processing the waste water.
The bi-products from burning syngas in a generator are C02 and H20 - which can then be returned to the photobioreactor for reuse.
