How to make cheaper second-gen biofuel

Producing second-generation biofuel from dead plant tissue is environmetally friendly - but it is also expensive because the process as used today needs expensive enzymes, and large companies dominate this market.

New material for solar panels could make them cheaper, more efficient

A unique solar panel design made with a new ceramic material points the way to potentially providing sustainable power cheaper, more efficiently, and requiring less manufacturing time. It also reaches a four-decade-old goal of discovering a bulk photovoltaic material that can harness energy from visible and infrared light, not just ultraviolet light.

Forest waste used to develop cheaper, greener supercapacitors

Researchers report that wood-biochar supercapacitors can produce as much power as today’s activated-carbon supercapacitors at a fraction of the cost – and with environmentally friendly byproducts. The report appears in the journal Electrochimica Acta.

New nanoparticles make solar cells cheaper to manufacture

University of Alberta researchers have found that abundant materials in the Earth's crust can be used to make inexpensive and easily manufactured nanoparticle-based solar cells.

New flow battery could enable cheaper, more efficient energy storage

MIT researchers have engineered a new rechargeable flow battery that doesn't rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage.

Solar is getting cheaper by the minute

Cheaper by the minute: That seems to be the story with solar photovoltaics in the United States these days.

Smartphones to get cheaper and cheaper

As the smartphone juggernaut rumbles on, vendors are increasingly turning their efforts to emerging markets, with less disposable income and a much lower smartphone penetration rate.

Visio.M MUTE EV is cheaper and lighter

According to a consortium of European automotive industry engineers, government officials and academics, the current crop of electric vehicles (EVs) now on the market could be better — a lot better.

Analyst says cheaper iPhones on the way

A Morgan Stanley analyst has predicted that Apple may introduce a line of cheaper iPhones in June.
