Comments Off on New 3D solar cells capture sunlight from every angle

Georgia Tech scientists developed three-dimensional solar cells which just hitched a ride to space this week on a SpaceX rocket. At the International Space Station , the solar cells will be tested to see how well they function and how they respond to space conditions. The solar cells have been designed to capture the sun’s rays from every angle, which could enable spacecraft to gain more power from a limited surface area. The experimental module blasted into space includes four different types of solar cells. One type is a “traditional planar” solar cell, and a second is a planar cell based on a formulation of low-cost materials: copper-zinc-tin-sulfide (CZTS). These materials cost about ” a thousand times less than the rare-earth elements ” like selenium and indium used in some solar cells. There are also two types of 3-D solar cells: one “based on CZTS” and the other “based on conventional cadmium telluride.” There are 18 solar cells total, and they will be tested in space for six months. Related: 2,500 orbiting solar “flying carpets” could power the planet 3-D solar cells could forever alter the way spacecrafts receive power. The Georgia Tech solar cells are described as miniature “towers” coated with a “photo-absorber.” Instead of requiring the sun to be right above them to work, the innovative 3-D solar cells can capture sunlight over longer periods of time. Georgia Tech Research Institute principal research engineer Jud Ready said in a press release , “We want to see both the light-trapping performance of our 3-D solar cells and how they are going to respond to the harshness of space.” After six months, the solar cells will return to Earth so scientists can study how they held up in space. According to Ready, “If it can survive in space, which is the harshest of environments from the standpoint of wide temperature swings, radiation, and numerous other factors, then we can be confident it will work well down on Earth.” Via Phys.org Images via Gary Meek, Georgia Tech

Comments Off on 5 Hearty Fall Pasta Recipes (and the Tools You Need to Make Them)

Photo: jules:stonesoup /Creative Commons From-scratch pasta is a little like fresh, homemade bread: If you take the time to make it, your guests won’t even pay attention to the rest of the meal. But fresh pasta is also a lot less time-consuming than it sounds — especially when you have the right tools. Try one of these hearty fall pastas — served with fresh herbs or butternut squash, walnut pesto or pumpkin-based dough — made with your own two hands (and, in some cases, a pasta machine attachment) and you’ll have a flavorful dish that makes for … Read the full story on TreeHugger

Comments Off on How Conservation Photography Is A Political Act

Mike Baird / CC BY 1.0 Conservation photography is just starting to find momentum. A combination of photography that is both art and activism, it is a special niche and one to which the environmental movement already owes a great deal. Sometimes we just have to see it to believe it, to understand the resonant beauty or shocking destruction and therefore move to act on the planet’s behalf. But, what really is conservation photography as separate from nature photography, wildlife photography or oth… Read the full story on TreeHugger

pink_dispatcher / CC BY-SA 2.0 The more people who get energy from clean sources like solar and wind, the better. That’s an unambiguous truism at this point. Yet two primary factors prevent more folks from plugging into renewable power: Cost and access. Most people have neither a) the option to plug into a big, centralized wind farm or solar array, nor b) the financial resources to pay the upfront costs for distributed projects like rooftop solar. … Read the full story on TreeHugger
