Float more boats while saving the climate?



Solar-powered power bank for TLUD fan, smartphones, LED lighting or other USB-powered devices

Improved lighting->reduction in blindness and increased educational opportunities

Smartphone->communications, mapping , micro-finance and millions of other benefits from apps

*TLUD stove

Cooking food - nutrition

Boiling water - kills most pathogens in water

Almost zero Carbon emissions from cooking using micro-gasification->reduction of climate change

Fuel pellets made from sustainable biomass waste eg. rice husk, saw dust etc.

Biochar from TLUD pellets->Long-term Carbon sequestration in the kitchen garden->reduction of climate change

Reduction in smoke with TLUD compared to a dirty stove or open fire ->reduction in smoke-related eye disease eg.blindness and respiratory illness


*Water filtration with biochar

Potable water (after initial boiling)

Decreased saline water and persistant organic pesticides (POP) and unhealthy bacteria or viruses that aren't killed from boiling water->decreased salt intake, toxins, water-borne disease eg. diarrhea

*Water conservation

Wastewater on kitchen garden increases water conservation for household->decreased cost of water bill and addresses potential water shortages due to population increase, climate change caused droughts, broken or inaccessible water infrastructure


Potable water->drinking, personal hygiene

Treatment of sewage/sewerage with biochar (biochar 'humanure')->organic fertiliser for the kitchen garden


Food hygiene

Biochar treated sewage/sewerage fertiliser->increased kitchen garden productivity/yield and nutrition (with many other benefits to the soil and climate)
