Blue Freedom – Providing reliable first aid electricity from hydropower

Electrical power supply is among the first critically important services in disaster areas. Especially natural disasters such as hurricanes, earthquakes or floodings lead to a destruction of the installed power grid and portable electricity becomes indispensable. One innovative solution is Blue Freedom Portable, a lightweight hydropower generator with 5W output capacity. With a weight of […]

Green solar grill

Derek Ham writes over at Barbeque Lovers about a solar-powered grill project he has been working on that uses latent heat storage to both extend cooking times, create hotter temperatures, and reduce the problem of intermittent sun. Based on technology developed by MIT professor David Wilson, the concept is expected to generate cooking temperatures of 450F, and […]

Uganda is up to speed – electric

“The car is ready, the Kiira EV can pick speed very fast, the motor stands strong, the reverse is perfect, it properly climbed a 55 degrees incline, the performance is good” exclaimed Mr Paul Isaac Musasizi, the Project Manager of the Vehicle Design Mission at Makerere University, which has produced Uganda’s first electric car. The vehicle for […]

Water and Salt = Light

Green House Co Ltd will release an LED lantern that generates electricity with water and salt. The lantern GH-LED10WBW does not require a dry cell or rechargeable battery and emits light when water and salt are put in the lantern. It can continuously generate electricity for eight hours per charge of water. To use the […]

Solar buddy – mobile off-grid system on wheels

Green Sun Rising Inc.  has developed and built a mobile solar off-grid system, the “solar buddy”. It can be wheeled around, can be directed to the sun for optimum harvest, and is a solar power generator. Perfectly quiet, its 240W DC module harvests solar energy and provides power for either direct use or battery charge. 1000 W AC 120V […]

An efficient and clean way to access water

For the many countries that are facing drought and dry conditions, access to clean and safe drinking water is a top priority. To answer this need, designers from the European team, CORDIS, have developed a desalinization process that utilizes solar power, is highly efficient and low cost. Current desalinization systems pressurize salt water to force […]

Liter of Light

The project, Liter of Light offers a sustainable alternative to kerosene lamps traditionally used in homes in developing nations. Kerosene lamps are dangerous and they emit toxic gases and large amounts of CO2. MIT student Alfredo Moser, envisioned an alternative lighting system made of recycled plastic water bottles, functioning as solar lamps. Illac Diaz, a […]

Eliodomestico – solar purification

There are many products that are designed to help irradiate the problems of water scarcity and purification of water supply. Eliodomestico is one such design, providing safe drinking water through renewable energy. Eliodomestico is an eco-distiller that runs on solar energy. The device can produce clean drinking water from sea or brackish water, through a […]

Turning Hydropower into Light – ES Pipe Waterwheel

The ES Pipe Waterwheel is a tool that utilizes hydropower generated from regular water taps by converting it to energy. The waterwheel works in the same way as a mini turbine does, the waterwheel pipe connects to a regular water pipe, as water runs, the turbines turn and generate energy. This energy is used to […]
