Geothermal Installation by the Numbers in Pennsylvania A lot of friends and neighbors ask why we switched to geothermal; here is the answer to that question by the numbers. All numbers used are verified averages, they are not estimates. In August of 2009 we installed a 5 ton geothermal heating and cooling system to replace our propane furnace and central air conditioner. The chart to the left shows the system cost. Don't let the initial cost scare you away - the signficantly lower cost of operation will make up for it. $3,000 - $4,000 per year to Heat with Propane The Latest Clean Energy Cocktail: Bacteria And Fungus By Jeff Spross "The Latest Clean Energy Cocktail: Bacteria And Fungus" By throwing together a common fungus and a common bacterium, researchers are producing isobutanol — a biofuel that gallon-for-gallon delivers 82 percent of gasoline’s heat energy. The more common ethanol, by contrast, only gets 67 percent of gasoline’s energy, and does more damage to pipelines and engines.
MIT researchers create super efficient 'origami' solar panels MIT researchers have created an origami-like solar structure that is much more efficient than current flat panels. The three-dimensional solar structure could, at least in principle, absorb a lot more light and generate more power than a flat panel containing the same area footprint. The hope is that all unused light which has been reflected off one panel would be captured by other panels.

Mycorrhizal fungi growing on a petri dish in Alia Rodriguez's lab Cynthia Graber This article was originally published on Gastropod. Unless you've been living under a rock for the past couple of years, you've probably heard about the human microbiome. Research into the composition, function, and importance of the galaxy of bacteria, fungi, and viruses that, when we're healthy, live in symbiotic balance in and on us has become one of the fastest moving and most intriguing fields of scientific study. But it turns out that plants have a microbiome too—and it's just as important and exciting as ours. In this episode of Gastropod, a podcast that looks at food through the lens of science and history, we look at the brand new science that experts think will lead to a "Microbe Revolution" in agriculture, as well as the history of both probiotics for soils and agricultural revolutions.
The microhydro plant My little paradise has a stream that provides enough water flow and head to run a small turbine, to provide electricity to my home. While writing this, the microhydro plant is being implemented, and here are some photos of the process. Since I usually like to start at the end, the first thing I built is the controller: It is an implementation of Jan Portegijs' "Humming Bird", with some changes and adaptations. The largest cost of the plant, by far, is in the piping for the rather long penstock. When the purchase was made and the truck arrived, we unloaded the pipes at different places, to get them as close to the installation area as possible.
Super Cheap Solar Cells Just Got Cheaper, Switch Gold For Nickel One of the major drawbacks of most renewable energy sources is high cost. In order to see a huge rise in the use of renewable energy sources, prices must come down. In the world of solar there have recently been some major breakthroughs in cost advantages and efficiency increases. Scientists at the University of Toronto in Canada have come up with a way to reduce colloidal quantum dot solar cell prices by up to 80%, by swapping out costly conductive gold for cheap nickel. Quantum dot solar cells consist of a silicon substrate that has a thin film coating of nanocrystals — or quantum dots.
11 cheap gifts guaranteed to impress science geeks Science comes up with a lot of awesome stuff, and you don't need a Ph.D, a secret lab, or government funding to get your hands on some of the coolest discoveries. We've got a list of 11 mostly affordable gifts that are guaranteed to blow your mind, whether or not you're a science geek. Click on any image to see it enlarged. 1. Aerogel Also known as frozen smoke, Aerogel is the world's lowest density solid, clocking in at 96% air. Ibasei's Cappa provides hydroelectricity on a small scale The Cappa compact hydropower generator can deliver 250 W of electricity Image Gallery (4 images) Despite being the most widely used form of renewable energy worldwide, hydroelectricity is generally reserved for large-scale commercial installations built around massive dams.
Following the Mycelial Path to Discovery and Saving the World by Carolyn Shea Paul Stamets ’79 turned his teenage curiosity about mushrooms into a singular path that not only led him to become a leading mycologist, entrepreneur, and author, but also put him on a trailblazing journey of discovery. Stamets has been a devoted acolyte, emissary, and evangelist of the fungi for more than four decades. Early on, he recognized that they were far more than forbidden fruits or culinary ingredients. To him, they and the mycelium—the hidden, subterranean networks of filaments—from which they spring (and which he’s dubbed “Earth’s natural Internet”) are powerful gifts of nature that hold the secrets to curing a multitude of medical and environmental ills. He’s made it his mission to not just uncover those secrets, but to dispatch the blindness and prejudices humans have toward mushrooms—what he calls “mycophobia”—that keep people from understanding how crucial these humble organisms underfoot are to our survival.
New device generates electricity from condensation MIT researchers have found a way to generate small amounts of electricity from condensation, by having electrically-charged droplets jump between superhydrophobic (water-repelling) and hydrophilic (water-attracting) metal plates. The advance could be especially useful in remote areas or developing countries, not least because it produces clean water as a side product. While pulling electricity out of thin air is a physical impossibility, producing it from water droplets in the atmosphere is very much within our reach. Some Earthy Figures and Facts About Solar Energy You Have to Know - Phoebe-Elle's blog Want more facts about solar energy? The best thing about it is that there are no rising and annoying importation costs of gas, oil or coal, which are by the way, increasing almost half the time. For more earthy figures and facts about solar energy, here they are: * In 2004, the solar cells' global production magnified by 60%.
