This glass sphere might revolutionize solar power on Earth German architect André Broessel, of Rawlemon, has looked into his crystal ball and seen the future of renewable energy. In this case it’s a spherical sun-tracking solar energy-generating globe — essentially a giant glass marble on a robotic steel frame. But this marble is no toy. It concentrates both sunlight and moonlight up to 10,000 times — making its solar harvesting capabilities 35 percent more efficient than conventional dual-axis photovoltaic designs. André Broessel was a finalist in the World Technology Network Award 2013 with the globe’s design and afterward produced this latest version, called Betaray, which can concentrate diffuse light such as that from a cloudy day. André Broessel’s latest invention looks like something out of a superhero movie. In reality, though, it’s a stand-alone solar energy generator. But Broessel’s invention may be more than just aesthetically pleasing. “We can squeeze more juice out of the sun,” Broessel says. Source: NewsDiscovery
X-Products 50 Round Magazines for AR-15, M1A, FAL, HK91, SR25, AR-10 – Gear Review X-Pr If you have already attempted to buy “high capacity” magazines at a gun show, you already know that all magazines are not created alike. If you haven’t, let us save you the trouble. If you don’t see big, reputable, American companies selling magazines other than standard capacity, for example, 7 rounds in a 1911, 30 rounds in an AR-15, or 20 rounds in an M1A, FAL or AR-10, STAY AWAY. Standard capacity mags are standard capacity for a reason. In the aftermarket high capacity magazine market there are very few companies that have gotten it right, and that are sold by mainstream firearm retailers next to the guns themselves. The AR-15 mag we tested is very different from both the M1A mag, as well as the Beta C-Mag. Not so with all of the 7.62/.308 guns. As you can see from the video and the pictures, we used our M1A that has been converted to a bullpup configuration with the Juggernaut Rogue chassis.
DIY Residential Wind Generators | DIY Solar & Wind DIY Wind Generators I made two wind generators, one was a motor from a stair master and one was from a tread mill. The third wind generator I bought. It’s rated for 1000 watts per hour at 22.3 MPH. If you want to build a wind generator for cheap then you can get any DC motor.

(3) Timeline Photos How to Build a Hot Tub I have lived in the Pacific Northwest with its cool, damp winters for more than 20 years, and I always wanted to build a hot tub. I wasn’t interested in one of the popular jetted tubs because their cost is prohibitive, the pump noise and vibration are bothersome, and the chemicals used to keep the water free of bacteria are a turnoff. The idea of using a stock-watering tank for a DIY hot tub project has been around for a long time, but all of the ones I’d seen were pretty unattractive. I wanted a setup that was nice-looking, easy to use, and economical. My hot tub dreams came together when I discovered a wood-fired spa stove made in Japan by a company called Chofu and imported by Island Hot Tub Co. Depending on how the soaking area is customized, the setup I’ve designed can cost less than $1,000. Soaking in a Wood-Fired Hot Tub Unlike a commercially available tub that only requires you to plug it in and set a timer, you’ll be more involved in the operation of your wood-fired soaking tub.
New Urban Mini Turbine for lantern poles introduced - The Archimedes 27 May 2014 | On the market launch of its ‘big brother’ – the Liam f1 – R&D company the Archimedes introduced a smaller version as well: the Liam Pole Mini Urban Wind Turbine. With half its size (ø 0.75cm) it will be mounted on a Cradle-2-Cradle lantern Pole manufactured by Sapa Pole Products. This new Product Market Combination (PMC) has the potential to save a lot of money on electrical infrastructure. When combining the Liam Pole urban mini wind turbine with a set of solar panels (PV), a LED lantern pole becomes totally self-sufficient. During daylight the solar panels and the turbine will charge a battery which will supply the light emitting diodes (LEDs) during night time, supported by the Liam turbine when enough wind is at hand. Because of its coned shape, the Liam Pole urban wind turbine will yaw itself in any wind direction starting from a windspeed of 2 m/s, even when it changes a lot. More information: sapagroup.com/nl/
Using Antacids as a Treatment for Exposure to Nuclear Fallout | This prepping and survival post contains important information on using simple OTC antacids as a treatment for internal contamination with radioactive isotopes from nuclear fallout. The radioactive fallout might come from a nuclear power plant disaster, or a dirty bomb, or a nuclear bomb explosion. Regardless of the source, at least several different types of radioactive elements are released, and these isotopes can end up in the air, food, and water. The most prevalent radioactive element in nuclear fallout is likely to be iodine-131 (a radioactive isotope of iodine). The treatment, as most preppers know, is potassium iodide (KI) or potassium iodate (KIO3) tablets. But what can you do for internal contamination with other radioactive elements? The treatment options are somewhat complicated, so I’ll just summarize them here. For exposure to radioactive strontium-90 or radium, ordinary antacids, available Over-The-Counter, are suggested, in two steps. 1. Learn more at Prep Blog Like this:
Heat Your Room For 15 Cents a Day | DIY Solar & Wind Heat Your Room For 15 Cents a Day The following video shows us an ingenious way to heat a whole room for under 15 cents or possibly even cheaper if you find cheaper candles or maybe larger ones. It’s simple, here’s what you need: Small candles such as the ones seen is the video which are found at IkeaA metal cake panTwo clay planter pots, one smaller than the otherA lighter to light the candles This awesome idea works on convection, which is accomplished by the air moving around between the two clay pots. The idea is if your only using only one or a few rooms, you can turn the thermostat down and save money.
HootSuite Versus Buffer for the Heavyweight Championship HootSuite versus Buffer for the Heavyweight Championship One question that has come up a lot recently from readers is why I use both HootSuite and Buffer. Isn’t one better than the other? I hope you won’t be too surprised to learn that there actually are good reasons for using both services, and in fact, I use the paid versions of both! While they may both fall within the category of “Social Media Management Software” I think you’ll find that there are stark differences and benefits to each. Before we get into how I use each service, let’s compare and contrast some of the key aspects that may determine for some whether or not the service is useful. Round One: Social Network Support Buffer Buffer supports personal Facebook profiles as well as business Facebook Pages. HootSuite HootSuite on the other hand has an even wider net. Round Two: Mobile Support Buffer has an app that allows you to view scheduled posts, as well as past posts (posts via Buffer). How I Use Buffer What do I share?
Wood Burning Heaters - Dragon Burners What causes wood smoke? Wood releases its volatile compounds when heated. Most of these compounds require at least 1,300°F to combust. They also store between 50%-60% of the total energy contained in the wood. A wood-fired combustion zone can be cooled to below the required temperatures for combusting smoke in a variety of ways. It follows, then, that the hotter the fire, the more complete the combustion, the higher the efficiency of the burn, and the less wood you have to chop. To insure a hot burn, the Dragon Burner primary combustion chamber (shown in the illustration as the horizontal tan component) is cast from an insulating refractory material. The importance of turbulence in burning wood The fire in the burn tunnel consumes the solids and releases the wood's volatile compounds. There is no smoke or pollution emitting from your stove pipe because all of the components of the wood are consumed. Burning Softwoods and Conifers Using the heat
Wind systems | YourHome The amount of renewable electricity harnessed from the wind is growing rapidly. Australia has an abundant wind resource, which, if used to generate electricity, could save significant greenhouse gas emissions. To take advantage of this resource, turbines must be installed in open sites on sufficiently tall towers. Appropriate wind system locations Begin investigating wind technology by ‘reality checking’ your general location. Coastal locations, and flat rural areas without significant vegetation or buildings, offer the most laminar wind flow. Urban areas have a poor wind resource that is usually extremely turbulent. Urban areas have a poor wind resource that is usually extremely turbulent. Wind systems installed on roofs typically do not produce much electricity, have short life spans and are thus never economically sound.
