Solar Lantern Bracelet: "Aahana" (2011)
End-users: off-grid Indian villagers. Manufactured and maintained in India.
[ Enscription ] - "Aahana," the name of the product, means "the first rays of the sun" in Hindi; Aahana bracelets are a conceptual portable light for Indian off-grid villages. 
[[ Above image information summarized ]]

[ Problems Addressed ] 
Over 404,700,000 Indians are off-grid (without electricity) in a country experiencing five trillion kilowatt hours of solar power a year; 80,000 villages lack electricity and mostly rely on harmful, expensive kerosene for light. 
[ Solution Rationale ] 
(1) Women Outdoors
On a consistent daily basis in India, millions of women spend one to two hours gathering water, traverse six to eight kilometers seeking firewood, and walk for hours to cities or markets to sell and buy goods. 
(2) Permaculture
Bracelets are ubiquitously auspicious and naturally worn across India by girls and women of all ages. 
(3) Power Hotspot
Eighty-three percent of the year consists of sunny days, equating to five trillion kilowatt hours of solar energy a year (far exceeding India’s annual energy consumption) - and India’s photovoltaic industry ranks sixth worldwide; women of a vast age group may be powerhouses of light energy without any change in their daily schedule or wardrobe. 
(4) Manufacturing Cost  
LED light saves 12-24 times as much energy as it takes to manufacture it. Due to the money saved from not buying kerosene, LED systems ‘pay back’ within two months.
