Cristian commented on Grow as A Tree When You Die

Interesting idea. It makes us part of a living cycle. 


Cristian commented on A Liter of Light

This is an interesting project that initiated in The Philippines. In 2014, it helped around 28000 homes and 70000 people in Manila. They have integrated an electronic circuit with a lighting emission diode and a photocell to have lighting during night. Although this idea may not reduce the overall energy consumption, it is certainly a good example of sustainable development for the low income population of the world and a smart eco-friendly solution.
