Researchers have developed a successful way to grow molecular wire brushes that conduct electrical charges, a first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs.

Engineering researchers in Canada have developed a tiling technique to create flexible solar cell panels. It is being tested on the curved roof of a campus bus shelter to power interior lighting.

Researchers have developed an "electronic glue" that could accelerate advances in semiconductor-based technologies, including solar cells and thermoelectric devices that convert sun light and waste heat, respectively, into useful electrical energy.

How much usable energy do wind turbines produce? It is a question that perplexes engineers and frustrates potential users, especially on windless days. A new study provides a formula for answering this vexing question.

If solar cells were transparent, they could be fitted to windows and building facades. Physical modeling helps in the development of suitable materials for transparent electronics and thus in creating the basis for transparent solar cells.

A transparent thin film barrier used to protect flat panel TVs from moisture could become the basis for flexible solar panels that would be installed on roofs like shingles.

A newly built "Cliffs Cottage" has all the latest technological innovations in sustainable living. Geothermal heating and cooling, two solar technologies, bamboo floors, furniture made from reclaimed wood, even cisterns that collect rainwater from the roof. The home has 3,400 square feet, but is so energy efficient that it can be heated and cooled for less than $75 a month.

Solar electricity has a bright future: It is renewable and available in unlimited quantities, and it does not produce any gases detrimental to the climate. Its only drawback right now is the price: the electric power currently being produced by solar cells in northern Europe must be subsidized if it is to compete against the household electricity generated by traditional power plants. Researchers are demonstrating how laser technology can contribute to optimizing the manufacturing costs and efficiency of solar cells.

Cost is one of the main disadvantages of the use of renewable energies. Researchers are aiming to make the development of efficient solar panels easier and cheaper. They propose the use of more economic synthesis methods using sulphur-based compounds (chalcopyrites) as an alternative to the ones used up until now.

A new concentration solar power module that produces heat, cold and electricity can be integrated to fa?ades or building roofs.
