Giving It The Green Light

Greener lighting at home

These days when we go shopping for a new laptop or television we are looking for the thinnest and lightest product available. Researchers have come up with graphene based electrode technology which make affordable and energy efficient display technology that could be a good alternative to light bulbs. Interestingly it is so sleek that it could even be used as wallpaper or applied to ceilings. Almost all modern devices use organic light emitting diodes (OLED) for display which are energy efficient but also have some drawbacks. The slimness comes with a cost making it very expensive compared to CRT or LCD type displays. OLED… read more

Graphene Paint: A solar wonder

Graphene Paint

A little while ago, we wrote about the potential new uses for ‘Graphene’; a natural element similar to silicon in its uses. Today we’re showcasing the possibilities for graphene paint. Basically, graphene is a light, efficient, and cost-effective alternative to silicon and other such elements. It’s planned uses include solar farms, vehicles, and electronics. Graphene paint opens the door to wonderful possibilities, and makes it widely available to the public, rather than just commercial/industrial uses. For now, graphene paint won’t be available until some time in the future. Still, scientists are very optimistic about the development and conversion of paint. Since graphene… read more

How Graphene Will Change Everything

Happy Valentines Day! If you’ve got nothing to do this evening, why not learn about graphene? You’ve probably heard quite a bit about graphene in the past year or so, and you’ll certainly be hearing more about it in the coming decade. Graphene has the potential to completely revolutionize the world of energy, batteries, solar power, automobiles, and more. It’s a magical element with mindblowing capabilities, and we’ve only scratched the surface on what graphene can actually do for us. We can use it to charge our cellphones in mere seconds, or put it to use creating an efficient solar… read more

Charge Your Phone In 5 Seconds

Graphene is an amazing technology. It’s biodegradable, flexible, super-conducting, and will literally change the world. In the next few years as the technology is refined, we’ll discover an entire array of possible uses, including the ability to charge your cellphone in seconds, your car in minutes, and after that? Well, I suppose we’ll have to wait around and see. In the meantime, check out how this technology is even possible:

Innovative Green Chargers

Graphene

Smart recharging options for gadgets are getting more interesting as advances in renewable technologies are made. Solar powered chargers are gaining in popularity, but there are also other resources that are becoming available for charging up devices. A new way being marketed at powering up gear is really an old way to create energy. Manual versions, like the YoGen Charger for Life are turning up, and this may be a practical object to have on hand. With no electrical outlets required and no battery to replace, the YoGen works solely on physical exertion. Chargers like these can conduct natural energy… read more

Hemp Could Yield Cheap Nanomaterials for Supercapacitors

hempfibers

Next generation energy storage may come from supercapacitors, devices that can not only store large amounts of energy, but can also both receive and deliver a charge quickly. One of the ‘wonder’ materials used for developing them is graphene, which can be difficult and expensive to make, but one group of researchers may have found a replacement that can be made from agricultural waste, specifically fibers from the hemp plant. Research at the University of Alberta into using plant waste materials as feedstock for commercial products has turned out a “graphene-like” nanomaterial that can function as electrodes in supercapacitors. The… read more

10 Green Tech Trends to Watch in 2013

10 Green Tech Trends 2013

Over the last couple of years, we have seen a large number of green and clean tech concepts go from idea to prototype to finished product, and because of the many environmental challenges (and consequent opportunities) facing us, it seems as if that trend is set to continue in the near future. A revolution in green materials has been entering the consumer market, with products made from recycled and eco-friendly components appearing in everything from food packaging to automobile interiors, and many customers want to see more of that. Some of the innovations that could also have a big potential… read more

Goodbye Silicon, Hello Graphene

Graphene electrodes

Silicon, the second most abundant element in the earth’s crust, and eighth most abundant in the entire universe, may have just taken a backseat to a lesser known element: Graphene. One of silicon’s best uses is in solar cells, though that may all change soon. According to MIT, Graphene has the potential of providing 60 percent more energy efficiency than silicon. So far, there aren’t any devices capable of using graphene to harvest energy, however, in the near future when companies begin testing and developing such machines, we may very well have a revolution in solar energy on our hands…. read more

New Technique Uses DVD Burner to Make Graphene Supercapacitors

Micro-supercapacitor

The next generation of supercapacitors could completely revolutionize energy storage devices, and a team at UCLA has developed a method for producing them with graphene, using a standard DVD burner. Supercapacitors exhibit the best characteristics of both batteries (high energy storage capacity) and capacitors (rapid charging and releasing of energy), and graphene, while considered a “wonder material” for those applications, has been a difficult one to work with. Graphene, essentially a pure carbon polymer, has a very high surface area (1500 square meters per gram), is an incredibly conductive superconductor, and is both flexible and durable. But previous to this… read more

Graphene Could Boost Solar Efficiency to 60%

Graphene

Current solar cell technology, using silicon as the base, has a theoretical limit to its efficiency, which falls somewhere around 30%, but solar cells made with graphene may push that limit up to somewhere around 60%. The results of a study from researchers at the Institute of Photonic Sciences suggest that graphene might be the material of choice for the next generation of photovoltaic cells, as it is “highly efficient” at generating electrons from light. When hit by light, silicon generates just one electron for each photon absorbed, which is only a fraction of the potential energy in the photon…. read more
