Light Dome was a collaboration art project between Zizi &Yo Yo, Winy Maas, a Dutch architect and lighting designer Rogier van da Heide of Arup from London.From January 1 to 6, 2005 the sky above Town Hall Square (Tallinn, Estonia) was filled with bright white balloons with the aim of disseminating innovative street lighting solutions to cities worldwide and enlivening a European-wide discussion working towards a more eco-friendly, cost-efficient strategy to light city streets.
Theses bio sand filters are quite cheap, easy to handle and repair, and durable.It is also expected that neighboring regions will replicate this technology.This initiative achieved a reduction in electricity consumption, greenhouse gases and carbon emissions.The young group members distributed bulbs that consume less electricity and consequently contributed to the reduction of the community’s electricity bills.The project concept is to reduce pollution and minimize greenhouse gases by constructing a sustainable biogas plant.
This plant would treat wastewater and produce biogas as a renewable energy source.
The only source is the river Minela and a few tanks.
In fact, people have to cover great distances in order to get clean water.
Youssef Ait Abi Braim’s invention deals with a daily problem, namely charging one’s cell phone.
His solution is a small solar cell which charges the battery of the cell phone with energy.
Now the availability of bio sand filters will bring the surface water to an acceptable level.
