Did Carl Sagan know something? Not sure if this is the right forum? This post is NOT about crop circles though it may appear so at first. Please read all three posts. Below is Chilbolton (UK) radio telescope. One year after the formation in the picture above another formation appeared in the same field. Two days after the face appeared this formation appeared. The following year this formation was found near another radio mast. The disc looks very much like a compact disc and contains a message. Beware the bearers of FALSE gifts and their BROKEN PROMISES. The upper/lower case is how it decodes. In 1974 Carl Sagan Transmitted a signal into space in simple binary form. Our DNA and the dominant substances that create life on earth. The star system that the signal was aimed at (M13) is very distant, infact its 26000 light years distant so we would not expect a reply until about 52000 years later (I did say it was distant). We'll deal with the easy ones first. The following was posted anonymously by a research biologist.
MIT Researchers are Printing Solar Cells on Sheets of Paper Published on August 20, 2011 by admin · No Comments Geek.com Solar power is a great alternative energy source, but it’s unfortunately a rather expensive one. However, researchers at MIT are working on a new and less-expensive way to make solar cells which involves printing them directly on to fabric or paper. We’re not talking about any fancy paper or fabrics. The MIT researchers discovered the printing process works on just about any paper, from regular printer paper, to tissue paper, and even to already-printed newspaper. It’s a much easier method than the current one, which needs super high-temperature liquids at several hundred degrees Celsius to create the cells. The substrate of the current method is usually glass and requires a number of other components that are expensive and result in a heavy, rigid object – and that’s not even taking into account the installation costs.

plant-e.com Home ‘Artificial leaf’ makes fuel from sunlight Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source. The artificial leaf — a silicon solar cell with different catalytic materials bonded onto its two sides — needs no external wires or control circuits to operate. Simply placed in a container of water and exposed to sunlight, it quickly begins to generate streams of bubbles: oxygen bubbles from one side and hydrogen bubbles from the other. The creation of the device is described in a paper published Sept. 30 in the journal Science. The device, Nocera explains, is made entirely of earth-abundant, inexpensive materials — mostly silicon, cobalt and nickel — and works in ordinary water. “I think there’s going to be real opportunities for this idea,” Nocera says.

The first power grid collapse took place on Monday, affecting seven states in northern India. The power went out at 2:35 a.m. and was brought back six hours later, only to go out again. Being someone of Indian decent, and having visited the country, I know that the country and its people are no strangers to power outages–sometimes they are government mandated to save energy and at other times they are brought on by power grid failures. Even though India is Asia’s third-largest economy, the country still depends on coal for its energy needs. With a population of over a billion–and counting–it is no surprise that the nation faced a supply shortfall of 8.6 percent this year in the month of June. Photo via ThinkProgress.org
In een ei-huis kun je overal duurzaam (over)leven De energie voor dit eivormige woninkje komt van zon en wind. Het huisje vangt en filtert regenwater en heeft zelfs een kitchenette die kan worden gebruikt om een warme maaltijd te bereiden. Wat het niet heeft: aansluitingen op het energie- en waternet. Off-grid leven (zonder aansluiting elektriciteit, gas en/of water) doe je niet zomaar. Nice Architects uit Bratislava ontwierpen de Ecocapsule in de afgelopen zeven jaar, een micro-schuilplaats met verschillende duurzame opties. De eivormige capsule is 4,5 meter lang, 2,4 m breed en 2,5 meter hoog. De ingebouwde 750W windturbine en 2,6 m2 hoog rendement zonnecellen (600W output) voorzien de Ecocapsule van energie. Potentiële kopers moeten nog even geduld hebben: de Ecocapsule is nog niet te koop. Misschien kan de Ecocapsule ook een duurzame oplossing zijn voor mensen die op dit moment geen veilig thuis hebben?

We dump 8 million tons of plastic into the ocean each year. Where does it all go? What happens to all our plastic bottles and lids and containers after we toss them out? Every single ocean now has a massive swirling plastic garbage patch The vast majority of plastic trash ends up in landfills, just sitting there and taking thousands of years to degrade. But there's another big chunk that finds its way into the oceans, either from people chucking litter into waterways or from storm-water runoff carrying plastic debris to the coasts. Now we can finally quantify this problem: A new study in Science calculates that between 5 and 13 million metric tons of plastic waste made it into the ocean in 2010 alone. Plastic debris in the Mediterranean Sea. And here's another surprise twist: We still don't know where most of that ocean plastic actually ends up. Yet those patches accounted for less than 1 percent of the plastic thought to be in the oceans — and no one quite knows where the other 99 percent went. China accounts for one-quarter of plastic ocean waste (Jambeck et al 2015)
Airborne robot swarms are making complex moves (w/ video) (PhysOrg.com) -- The GRASP Lab at the University of Pennsylvania this week released a video that shows their new look in GRASP Lab robotic flying devices. They are now showing flying devices with more complex behavior than before, in a fleet of flying devices that move in packs, navigate spaces with obstacles, flip over and retain position, and carry out formation flying, The researchers have cut down these robotic creature-like drones to small size to what they call “nano-quadrotors.” The video shows them in action: not just engaged in formation flying, but also creating an impressive looking figure-eight pattern. The video says as much about the GRASP Lab as the flying machines, in that the GRASP Labs seems intent on raising the bar on what robot swarms can achieve. Still, the video is clear proof that the team developers, Alex Kushleyev, Daniel Mellinger, and Vijay Kumar, are able to showcase complex autonomous swarm behavior. The key word is agile.

Countries Around The Globe Opting For Solar Power Solar power, which converts sunlight into energy, is beneficial for reducing our carbon footprint and has been accepted as a greener alternative for harvesting power. While harvesting solar energy has a carbon footprint of its own, research shows a solar panel’s carbon footprint is at least 20 times smaller than that of coal. As of late, solar energy is slowly transitioning from an alternative energy source to a preferred energy source. For starters, the Australian government recently announced a $1.3 million grant to researchers who specialize in solar power. Resources minister Martin Ferguson said in an e-mailed statement: “From techniques to improve the efficiency of solar cells made from low-cost and readily available organic materials, to investigating ways to optimize hybrid solar-diesel systems in remote areas using smart grids, the Skills Development Program is helping to drive Australian solar innovation.” Villager, and tailoring shop owner, Rekibul Rahman shares:
