Melt a stack of pennies, burst a glass bottle, damage various food items, and incinerate wood using the power of the Sun! This 4 foot magnifying lens will melt concrete, and nearly anything else that gets in its way. nnhttp://www.thekingofrandom.comnnMusic by http://www.danosongs.com (Crazy from the message)nnProject inspired by: drsimons http://youtu.be/pPgHkSMQP5snnWARNING: This project should not be attempted without adult supervision and adequate training. Misuse, or careless use, of tools or projects may result in serious injury property damage, or death. Concentrated solar energy can start fires and cause personal and property damage. Extreme caution is advised. Use of this video content is at your own risk.nnLEGALITIES: Some people have asked about the legality of treating pennies in this manner. The federal law states that there are exceptions made for use as "educational, amusement, novelty, jewelry, and similar purposes as long as the volumes treated and the nature of the treatment make it clear that such treatment is not intended as a means by which to profit solely from the value of the metal content of the coins."

I'm impressed at the results, and excited at the power available through this Fresnel lens that I've nicknamed my "Solar Scorcher".nnIn the summer, the sunlight at this spot is around 2000ºF, maybe more. Enough to melt spots of concrete into glowing orange liquid. nnI'm curious to see what I can do with all this heat so I've filled a glass bottle with water and I'll punch a hole in the cap. It's incredible to see that the instant I focus my lens on the bottle, it starts smoking. Just a few moments later this water is so hot it's boiling, and I'm a little nervous the bottle might blow. Yep, there it goes. I'll try burning a penny, and, wow, it melted. How about a stack of pennies? Yep, they're nothing but liquid metal now, and I'm thinking that slag in the mixture must be what's left of the copper coating. It's only taking about 4 seconds to melt these. nnWell, I'm convinced there's an insane amount of power behind these lenses. If you'd like to see where I got this one, take a look at my video on how I hacked it out of an old TV. nnhttp://www.youtube.com/watch?v=XFw7U7V1HoknnThis one boiled water in less than a minute, welded a nickel to concrete, and instantly torched any piece of wood in it's way.

A penny-sized rocket thruster may soon power the smallest satellites in space. The device, designed by Paulo Lozano, associate professor of aeronautics and astronautics at MIT, bears little resemblance to today's bulky satellite engines, which are laden with valves, pipes and heavy propellant tanks. Instead, Lozano's design is a flat, compact square — much like a computer chip — covered with 500 microscopic tips that, when stimulated with voltage, emit tiny beams of ions. Together, the array of spiky tips creates a small puff of charged particles that can help propel a shoebox-sized satellite forward. nnRead more: http://web.mit.edu/newsoffice/2012/microthrusters-could-propel-small-satellites-0817.htmlnnVideo: Melanie GonicknAdditional images: Fernando Mier Hicks/NASA Less

580 Watts RV Solar Power Install. See Full Blog Post - http://www.loveyourrv.com/my-friends-awesome-580-watt-rv-solar-power-system/nnI've admired my friend Eddie's photos of his solar install for a while now and finally had the chance to see it for myself in real life. We were dry camped together for several days and had a great time chatting about RVing and all the mods, repairs and upgrades we have done to our rigs.nnI thought other RVing folks would love to get a look at the system and he was kind enough to let me video it and give us some details on the equipment used and how he installed it all.nnI think you'll agree he has done a beautiful job on the installation and wiring. I can attest to the fact that it works really well too. While we were boondocked they had no problems running all sorts of things in their rig, from satellite TV to a washer and dryer, deep freeze, kitchen appliances, electronics, etc, etc.nnIf you'd like to see more of photos of Eddie's solar and power systems as well as numerous other mods and upgrades he has made to his rig head over to the RV Happy Hour.

A dish/engine system uses a mirrored dish similar to a very large satellite dish, although to minimize costs, the mirrored dish is usually composed of many smaller flat mirrors formed into a dish shape. The dish-shaped surface directs and concentrates sunlight onto a thermal receiver, which absorbs and collects the heat and transfers it to the engine generator. The most common type of heat engine used today in dish/engine systems is the Stirling engine. This system uses the fluid heated by the receiver to move pistons and create mechanical power. The mechanical power is then used to run a generator or alternator to produce electricity. Less

Originally published on August 26, 2013nnAircraft designer Titan Aerospace unveiled last week its Solara 50 and 60 unmanned aircrafts, the world's first atmospheric satellites powered by the sun with a mission range of over 4 million kilometres.nnAn atmospheric satellite is a drone that can conduct most of the operations of an orbital satellite, but is much cheaper and more versatile. nnAmong the applications of a Solara aircraft there are disaster recovery, weather monitoring, communications relay, oceanographic research and earth imaging.nnAccording to reports, Solara 50 and 60 can be launched at night using power from internal battery banks. nnWhen the sun rises, the solar panels covering the crafts' wings and tails, store enough energy to allow them ascend to a position of 20 km above the sea level and to stay aloft continuously for five years, without ever having to land and refuel. nnThe aircrafts will operate in an atmospheric sweet spot known as the tropopause where winds are generally less than 5 knots.nnDespite its massive dimensions, Solara 50 only weighs about 160 kg, and can carry a payload of 32 kg. According to reports, differently from satellites, it is possible to get the payload back at the end of its five years endurance. nnAs for the speed, Solara 50 can travel at 104 kilometres an hour (about 64 MPH).nnAccording to reports, smaller versions of Solara have already flown, and Titan Aerospace is planning to start selling operational systems in less than a year which opens up possibilities like regional internet or a version of Google Maps with real-time images. nn--------------------------------------------------------nnTomoNews is your daily source for top animated news.

Solar Storm Barrelling Towards Earth This Weekend : www.thelivingguru.com Are We Safe From Solar Storms? www.thelivingguru.com What is a SOLAR STORM? www.thelivingguru.com According to reports, The space weather forecast for Earth looks a bit stormy this weekend, but scientists said not to worry. A solar storm was due to arrive Saturday morning 13 July 2012 and last through Sunday 14 July 2012, slamming into Earth's magnetic field. Scientists said it will be a minor event and they have notified power grid operators, airlines and other potentially affected parties. In severe cases, solar storms can cause power blackouts, damage satellites and disrupt GPS signals and high-frequency radio communications. Airlines are sometimes forced to reroute flights to avoid the extra radiation around the north and south poles brought on by solar storms. Were there past incidents of solar storm heading towards earth? In 1989, a strong solar storm knocked out the power grid in Quebec, causing 6 million people to lose electricity. Some satellites in polar orbits lost control for several hours. GOES weather satellite communications were interrupted causing weather images to be lost. NASA's TDRS-1 communication satellite recorded over 250 anomalies caused by the increased particles flowing into its sensitive electronics. The Space Shuttle Discovery was having its own problems.

Scientists at Nasa have recorded a huge solar flare caused by a large magnetic eruption. The space agency's Solar Dynamic Observatory filmed the images on February 24. The M rated event is not the strongest solar flare ever recorded but was still big enough to kick up a huge tendril of plasma, known as a solar prominence. The entire eruption lasted for about 90 minutes. Thursday's flare was the latest in a recent series of sun storm emissions, but its blast was directed away from the Earth and is not expected to pose any disruption to satellites or other electronic systems. Scientists use a three tier system to classify solar flares; Class X are the largest and most powerful, Class M are medium but still considered very large, while Class C are the weakest. Less

On July 23, 2012, Earth narrowly escaped a solar blast that could have knocked out power grids and disabled satellites and GPS. On July 23, 2012, Earth narrowly escaped a solar blast that could have knocked out power grids and disabled satellites and GPS. Had the solar eruptions occurred 9 days earlier, their impact would have been felt. That news was announced recently by scientists from the University of California, Berkeley. According to their report, the averted blast was likely equal to the one that hit in 1859. Eyewitness accounts of the mid-19th century hit describe night being as bright as day and a sky filled with brightly colored flashes. Telegraphic service was adversely affected beyond control. The fallout of the 2012 event would have been far worse because of our dependence upon vulnerable technologies. Magnetic surges could well have wiped out communications, power, and navigational abilities for large crafts in the air and at sea. The financial tally of the damages likely to have been rendered was estimated at 2.6 trillion dollars. Recovery time after such an event is said to be between 4 and 10 years. Researchers say that the near miss is a reminder of how little is known about solar blasts, and how crucial a better understanding of them is. Less

Two years ago, a NASA observatory picked up on a solar storm that came close to causing serious technical problems here on Earth. Two years ago, a NASA observatory picked up on a solar storm that came close to causing serious technical problems here on Earth. Solar storms, or coronal mass ejections, are composed of gas clouds and magnetic field lines that alter the magnetic fields of the planets they hit. In 2012, experts say that a coronal mass ejection came within a week of hitting our planet. Disruptions to electricity and satellite technology would have been felt across the globe if the solar storm hit Earth. Blackouts would cause most toilets, which are powered by electricity, to stop flushing. According to estimates from the National Academy of Sciences, repairing infrastructure damaged by a coronal mass ejection would cost around two trillion dollars. The last time a significant solar storm hit Earth was back in the year 1859, in what’s known as the Carrington event. Pete Riley, a physicist at Predictive Science Inc. is quoted as saying: “It’s likely that the Carrington event was also associated with multiple eruptions, and this may turn out to be a key requirement for extreme events.” Experts predict that there is a 12 percent chance of a solar storm hitting our planet in the next ten years.

There’s a big solar storm headed for Earth and when it arrives it’s expected to have an effect on the power grid, radio transmissions, and satellites. There’s a big solar storm headed for Earth and when it arrives it’s expected to have an effect on the power grid, radio transmissions, and satellites. It isn’t anticipated that it will cause severe problems, but scientists are concerned about the size and location of the sun’s recent eruptions. A smaller solar event occurred on September 8th and it’s impact has already reached our planet, causing a slight disruption to radio communications when it did. The larger of the two developed on the 10th and its aftermath is still en route.When weather events on the sun such as these happen, they result in the creation of a coronal mass ejection, or a CME. Billions of electrically charged particles form a traveling mass that can mess with a planet’s magnetic sphere if it gets too close. In the case of Earth, with all of its electric Less

Just before noon on September 1st 1859, the British astronomer Richard Carrington witnessed the largest solar flare ever recorded. The solar flare ejected a plasma cloud that traveled from the surface of the Sun for just over eighteen hours before finally reaching the Earth. As the dawn broke on September 1 1859, the skies all over planet Earth erupted in red, green, and purple lights so brilliant that newspapers could be read as if it were daylight.
Stunning northern lights pulsated at the tropical latitudes over Cuba, the Bahamas, and Jamaica.
Telegraph systems worldwide went haywire. Spark discharges shocked telegraph operators and set the telegraph paper on fire. Even when the telegraph operators disconnected the batteries powering the lines, electric currents in the wires still allowed messages to be transmitted.
A sun storm of this sort today could cause billions of dollars of damage to the Earth's satellites and terrestrial power grids. And disrupt radio and cell phone communications.
In the 160-year recorded history of geomagnetic storms, the Carrington event is the biggest. Less

The SOHO spacecraft has recorded the effect of all this rising energy. Its ultraviolet sensors show a wavy pattern of gas on the sun's surface, along with the super-hot halo of gas called the corona. nnThe white regions are places where the rising gas suddenly escapes.nnImmense loops of ionized gas, ten times the diameter of Earth, rise and fall back. These solar prominences are hot, about 60,000 degrees Celsius.nnBut there are times when the release of energy on the solar surface gets bottled up, by magnetic fields generated by the sun's spinning turbulent core.nnUsing data from the sun's exterior, scientists have modeled these fields as they erupt all around the sun's surface, twisting and looping.nnHeat rising toward the surface follows these magnetic field lines, which can also stifle the rising columns, forming relatively cool patches. nnThat's where sunspots form. Four centuries ago, Galileo Galilei was the first to argue that these blotches were actually on the Sun's surface, though he suspected they were clouds.n nTheir nature remained unclear until 1908, when the astronomer George Ellery Hale demonstrated the link between sunspots and intense magnetic fields.nnOver the years, scientists have drawn their strange shapes in an effort to understand them.nnWhat they didn't see, until recently, was the heat and pressure building around them.nnUsing data from the Solar and Heliospheric Observatory, SOHO, scientists are learning to read undulations on the surface of the sun, the result of pressure waves ricocheting through its volume. nnLike the study of earthquakes on Earth, this field, called Heliosiesmology, is a window on the movements of gas inside the sun. It's also generating predictions of flares and sunspots, including those forming on the far side.nnDetectors aboard the SOHO spacecraft have managed to catch the moment when the energy capped by a sunspot is suddenly released.nnA shock wave travels rapidly outward, like a solar tsunami, with enough force to circle the star. nnThat signals the start of a coronal mass ejection, or CME, a massive eruption of particles and hot gas. nnWith a coronagraph to block out the bright light of the sun, you can see how violent our sun can get. nnIf a CME is detected blasting out from behind this artificial eclipse, you know that satellites and power systems on Earth are going to get hit hard, especially if it has been launched in the direction of where Earth will be in its orbit in about 24 to 36 hours.nnThe sun sends a wave of energetic particles that will crash into Earth's magnetic field. nnAnd as more and more of the ground around Earth gets carpeted with conductive metal, the chances are that all that juice will "fry" something vital to humanity.
