Slingshot- vapour compression water-purification machine -can produce 30lts of distilled water per hour using 1 kwatts of electricity-cost few thousand dollars--support 300 people
Another cheaper technology by Alfredo Zolezzi of Chile's AIC--sanitizes water by converting it into plasma state through high intensity electrical field-microbiological content eliminated using electroporation,oxidation,ionization,UV ,IR and shockwaves--used for 3 years in a slum at Santiago- village units cost 500$,home units lesser.
Energy:
Sources and Storage
1/fuel from algae
2/micro-scale graphene based supercapacitors - recharge laptops in seconds,electric cars in minutes
3/solar panel cost dropped by 97.2% in past 35 yrs.In India solar energy cheaper than diesel.
unilimited water and unlimited power==> unlimited food --> Singapore having vertical farms,eggs from plants,meat from tissue engineering and 3d-printing.
