Eliodomestico Solar Water Filter

Designer Gabriele Diamanti invented Eliodomestico, an eco sea water distiller running on solar power to provide safe bacteria-free drinking water for people in developing countries.

Solar Water Heating Systems

Solar water heaters – also called solar domestic hot water systems – can be a cost-effective way to generate hot water at home. They can be used in any climate, and they use free fuel – sunshine.

Solar Bottle Lamp

Alfredo Moser came up with the solar bottle lamp – it illuminates dark spaces during the day without electricity, by using a plastic bottle filled with water and a bit of disinfectant.

‘Sunplace’ Solar Powered Grill

The SUNplace is a “solar cooking table,” a collaborative project by designers Francesca Lanzavecchia and Hunn Wai, intended for a group of chefs to cook together and prepare a meal using sunlight.

‘Powerwall’ Home Solar Batteries

The Powerwall is the new Tesla solar battery unit to power households. The battery is affordable, comes with a 10 year warranty, and has an elegant design that easily mounts on the wall.

Transparent Solar Concentrator

Michigan State University researchers designed a transparent luminescent solar concentrator that can be used on buildings, cell phones, and other devices with a clear surface that harvests energy.

Smart Power Outlets Prevent Fires

Intelligent power outlets can conserve energy and prevent deadly accidents like house fires. John La Grou is working on the Electrical Fault Circuit Interrupter – EFCI – using microprocessors and RFID tags.

‘AMBRI’ Large Scale Batteries

Donald Sadoway is working on a large scale battery – an inexpensive, efficient, three-layered battery using “liquid metal” – to provide storage for renewable energy, for supply to meet the demand, rain or shine.

Ancient ‘Baghdad Battery’

Dated to 200 BC, the so called ‘Baghdad Battery’ can produce almost a volt of energy. It consists of a clay jar, a copper tube wrapped around an iron rod, and an acidic fluid transferring electrons.

Vortex Wind Generator

Vortex Bladeless is a new model of wind generator that bends in the wind and produces power at its base by utilizing the vortex created when wind moves around it. It’s silent and completely safe for birds.

Teen Built Homemade Windmill

A 14 years old Malawian inventor William Kamkwamba built an electricity-generating windmill from spare parts, working from rough plans he found in a library book “Using Energy.”

Hot Water With Rocket Wood Stove

Using some recycled parts and a small rocket stove you can heat and pump hot water without the need for electricity. You can also easily make the rocket stove yourself from four concrete blocks.
