The all-carbon solar cell consists of a photoactive layer, made of carbon nanotubes and bu...

Researchers at Stanford University have developed an experimental solar cell made entirely of carbon. In addition to providing a promising alternative to the increasingly expensive materials used in traditional solar cells, the thin film prototype is made of carbon materials that can be coated onto surfaces from a solution, cutting manufacturing costs and offering the potential for coating flexible solar cells onto buildings and car windows.  Read More

Is there a future for synthetic gasoline? (Photo: Shutterstock)

Air Fuel Synthesis, Ltd. (AFS), a small company in the northern English county of Durham, has recently made headlines for a chemical process that claims to synthesize gasoline from air and water. In essence, AFS is using energy to unburn fuel so that it can be burned as fuel again – a great deal of energy. Sixty kWh of electric energy are used up to store 9 kWh of that energy in a liter of gasoline. When you take into consideration that gasoline vehicles are about 15 percent efficient, a car fueled with synthetic gasoline would use roughly 35 times more energy on a given trip than would an electric vehicle. Not, it would seem, a prescription for a commercially valuable green product.  Read More

MIT has developed pencil 'leads' that can be used to draw gas sensors onto paper

We’ve already seen a pen with silver-based ink, that lets its user draw electrical circuits on ordinary paper. Now, scientists from MIT have brought similar “hands on” technology to the humble pencil – they’ve compressed carbon nanotubes together to form a pencil lead substitute, that has been used to draw gas sensors onto regular paper imprinted with gold electrodes.  Read More

UBC promises that each frame is hand built in clean room conditions in accordance with mot...

The UBC coren is what happens when creative minds get to run amok without the usual constraints imposed by reality. The new single speed bicycle combines a unique shape, belt drive and plenty of high-tech composite.  Read More

In the near future, genetically-altered Ralstonia eutropha bacteria could be used to conve...

Scientists at the Massachusetts Institute of Technology (MIT) have succeeded in genetically altering Ralstonia eutropha soil bacteria in such a way that they are able to convert carbon into isobutanol, an alcohol that can be blended with or even substituted for gasoline. It is hoped that once developed further, this technology could help reduce our reliance on fossil fuels, and lessen the amount of carbon dioxide released into the atmosphere by smoke stacks.  Read More

Diamonds may be forever, but they aren’t what they were. True, they shine just as brightly and they’re as hard as ever, but scientists from the Carnegie Institution of Washington are giving them some competition. An international team led by Carnegie’s Lin Wang have discovered a new substance that is not quite crystalline and not quite non-crystalline, yet is hard enough to dent diamonds.  Read More

As manufacturers of smartphones and mobile devices strive to make their products increasingly portable, they repeatedly come up against the constraints of existing battery technology. However, Xiaodong Li, a professor at the University of South Carolina (USC) believes that we will soon be able to employ the clothes we wear to help overcome such challenges and to this end, Li has transformed T-shirt material into an energy storage medium which could one day be used to power portable devices.  Read More

Researchers at MIT have developed a new type of photovoltaic cell made with carbon nanotubes that captures solar energy in the near-infrared region of the spectrum, which conventional silicon solar cells don’t. The new design means solar cell efficiency could be greatly increased, boosting the chances to make solar power a more popular source of energy.  Read More

While there are plenty of ways to make carbon-based products from CO2, these methods usually require a lot of energy because the CO2 molecules are so stable. If the energy comes from the burning of fossil fuels, then the net result will be more CO2 entering the atmosphere. Now a material scientist at Michigan Technological University has discovered a chemical reaction that not only soaks up CO2, but also produces useful chemicals along with significant amounts of energy.  Read More

A researcher from Adelaide's Flinders University has developed a prototype solar cell that...

Imagine if every window of the 828-meter (2,717-foot) high Burj Khalifa in Dubai was capable of generating electricity just like a PV panel. That's the promise of solar window technology like the RSi and Sphelar cells systems. Rather than using costly silicon for window-based collection of solar energy, Dr Mark Bissett proposes using a very thin layer of carbon nanotubes instead.  Read More
