How to teach children to purify water ?
JOEL OMINO SECONDARY SCHOOL, KISUMU , KENYA
Students were suffering from water born diseases caused by drinking unsafe water in the school and at home. This affected their learning in school and regular duties as well as faced with huge medical bills.
Students were trained on how to make and maintain Biosand Water Filter. They were able to pass this knowledge and skill to the community.

What does it take to build a sustainable civilization with modern comforts?
Open Source is not just software
Open Source Ecology is a network of farmers, engineers, and supporters that for the last two years has been creating the Global Village Construction Set, an open source, low-cost, high performance technological platform that allows for the easy, DIY fabrication of the 50 different Industrial Machines that it takes to build a sustainable civilization with modern comforts.
The GVCS lowers the barriers to entry into farming, building, and manufacturing and can be seen as a life-size lego-like set of modular tools that can create entire economies, whether in rural Missouri, where the project was founded, in urban redevelopment, or in the developing world.
How to lighten houses that are dark even during daytime?
Build a solar bottle bulb
The communities who benefit from this idea live in areas where the houses hardly have windows and live in darkness even during daytime. Their solution up until this innovation was to turn on the light bulb and use electricity.
Alfredo Moser, the inventor of the lamp says:
It's a divine light. God gave the sun to everyone, and light is for everyone. Whoever wants it saves money. You can't get an electric shock from it, and it doesn't cost a penny.

Building a windmill
At age 14, in poverty and famine, a Malawian boy built a windmill to power his family's home. Now at 22, William Kamkwamba, who speaks at TED, here, for the second time, shares in his own words the moving tale of invention that changed his life.

How to protect the cattle from lion attacks ?
Solar-powered solution invented by 13-year-old Richard Turere
Richard Turere, 13, doesn't like lions. "I grew up hating lions very much," says Turere, who is from Kitengela, just south of the capital Nairobi, Kenya. "They used to come at night and feed on our cattle when we were sleeping."
At the age of 11, Richard decided it was time to find a solution for protecting the family's cows, goats and sheep from being eaten by lions.
"One day, when I was walking around," he says, "I discovered that the lions were scared of the moving light."
He started to work on a system and despite the fact that had never received any training in electronics or engineering, he came up with a simple and low-cost system to scare the predators away. He arranged a series of flashing LED bulbs wired to switches and a car battery powered by a solar panel. It worked, since then his family has not lost any livestock.
"One thing that's unique about Richard is that if you give him a problem, he'll keep working at it until he can fix it," says leading Kenyan conservationist Paula Kahumbu. "He doesn't give up; he doesn't find things too difficult; he's not afraid of being unable to do something and I think this is why he is such a good innovator."

How to heat a room for little money
Using 2 or more clay pots of different sizes, a metal cake pan or bricks and small candles.
This awesome idea works on convection, which is accomplished by the air moving around between the two clay pots. This helps create a forced air effect which pushes the hot air around the room.
Honeybees and the bio-dynamic way to save them
TOP expert: Yossi Aud
This growing method is substantially friendlier towards the bees in comparison to industrial beekeeping. This method allows the bees to live sustainably, consume their own products and to stay healthier. Another aim of these centers is to encourage and promote growing bees on the city’s rooftops. In this way the centers aid in the re-establishment of honey bees to the city and the environment in general.
