In a previous project I found a free tv and turned it into a giant solar scorcher. This shoots out a deadly beam of sunlight, that's hot enough to abuse food, melt metal and burn things you probably shouldn't. Today seemed like a good day to play with my Solar Scorcher. I positioned my frame and found the focal point, then added some concrete tiles as a base for my projects. Ok, I've got power, and I'll test it out with this piece of wood and when the light makes contact.
I've got instant fire. The sunlight at this spot is around 2000 degrees Fahrenheit, enough to melt this spot of concrete into a glowing orange liquid. I'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. The glass pieces are melting and that's cool,.
But now I want to try this on some food. I'll get some hot dogs, and when they hit the beam they really do get hot. This might be a little well done for my taste, and I'm still hungry so let's try an egg. The egg is actually working very well. It's so reflective it doesn't burn as fast, and even my wife is interested. A little salt and pepper and it's tempting to try a bite. Ok, so I wasn't actually expecting to eat this, but it looks safe enough, and.
Even my kids are anxious to try. Surprisingly, it's pretty good. Alright, let's see what else this will do. 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, and melting metal is really great, but now I want to see something burst. I wonder what would happen to this egg It's spewing some kind of debris and smoking like crazy. I hear.
Some little pops and it's even forming some interesting growths. huh, Look at that. But no explosion. How about if I put a pop top on this bottle of water and let the pressure build up Yeah, that's what I'm looking for. Let's do that again. The lid is back on, and pressure is building. Awesome! Alright, the sun is setting and I've readjusted my Aframe. I'm just wondering if this would ignite gasoline. It does. Hopefully it goes without saying that this is very dangerous and you shouldn't try this at home. Well, 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 tutorial on how I hacked it out of an old TV. This one boiled water in less than a minute, welded a nickel to concrete, and instantly torched any piece of wood in it's way. Well that was fun, but I'm still hungry so I'll put everything away and go get some real home cooking. That's it for now. If you liked this project, perhaps you'll like some of my others.

SATELLITE SPINNER ENGLISH 11MB.wmv
This satellite spinner is one of the most beautiful spinning toys. you need a plastic pen with a lid and a cross member which can be attached to the back of the pin. lift the clip of the lid of the pen so that it is at an acute angle. press it on your index finger and start spinning and you will be surprised that the pen spins around your finger. now attach a cross member to the little hole at the bottom of the pen. the two arms look like.
Is There A Used Solar Panel Market Out There
Is there a use solar market out there that you're aware is a question I asked John Shaw project engineer for Bella Energy. A little bit on number one that it is more of a market for thermal panels mostly I have a feeling because twenty years ago in the eighties were tax credits and at that time most people can only afford in the realm of solar most people could only afford solar thermal panel solar electric were out there, but they were really being offered to the public so the.
So there are turned over twenty yearold thermal panels that he either people want hear it up as they looked ugly or because base you know, the office system had broken down when in maybe it's a Palm not the panel said he can pick up some solar panels used from even if there were twenty year old PV panels out there I don't think that I really don't think they wouldn't be broken down at the would be still working so I don't I just think that it's a matter.
Energy 101 Solar PV
MR. All right, we all know that the sun's energy creates heat and light. But it can also be converted to make electricity, and lots of it. One technology is called solar photovoltaics or PV for short. You've probably seen PV panels around for years, but recent advancements have greatly improved their efficiency and electrical output. Enough energy from the sun hits the earth every hour to power the planet for an entire year. Here's how it works. You see, sunlight is made up of tiny packets of energy called photons.
These photons radiate out from the sun, and about 93 million miles later, they collide with a semiconductor on a solar panel here on Earth. It all happens at the speed of light. Take a closer look, and you can see the panel is made up of several individual cells, each with a positive and a negative layer, which create an electric field. It works something like a battery. So the photons strike the cell, and their energy frees some electrons in the semiconductor material. The electrons create an electric current, which is harnessed.
By wires connected to the positive and negative sides of the cell. The electricity created is multiplied by the number of cells in each panel and the number of panels in each solar array. Combined, a solar array can make a lot of electricity for your home or business. This rooftop solar array powers this home, and the array on top of this warehouse creates enough electricity for about a thousand homes. OK, there are some obvious advantages to solar PV technology. It produces clean energy. It has no emissions, no moving parts, it doesn't make any noise and it doesn't need water.
The Future of Flight
These are the technological developments that will allow us to move ourselves and our cargo cheaper, greener, and faster, through the air, going forward. This is the future of flight. With the first allelectric twinengine, selfpowered aircraft successfully crossing the English Channel this month, and the ongoing effort of the Solar Impulse team to become the first completely solarpowered aircraft to fly around the world, the amount of innovation targeting the aviation industry is eyeopening. Within the next year, unmanned, solarpowered drones like the Silent Falcon will hit the commercial UAV market.
The Joby Aviation S2 electric is a proposed Vertical Takeoff and Landing aircraft that could be five times as efficient as a conventional personal airplane. Airbus' two passenger version of the EFan will use onboard lithium batteries to power two electric engines. The Aeroscraft ML868 could lead a comeback of giant airships. The 770 footlong behemoth can carry 200 tons with cargo bays larger than any current air, truck or rail transport vehicle. Aerion's AS2 is the first supersonic commercial jet since the Concorde. It will fly at a speed of Mach 1.6. Laminar flow technology and better wing design will reduce drag by 20.
By the middle of the 2020's we'll likely see solar powered drones delivering broadband to millions for a fraction of the cost of traditional satellites. Building on the concept of drones and autonomous flying technology, fullyautomated planes will take to the skies to revolutionize not just the air cargo delivery industry, but possibly personal air travel as well, much like what's happening today with driverless cars. By 2030, plantbased fuels should account for 30 or more of an airlines' fuel consumption. Airbus' hybrid commercial airliner will emit barely any emissions or noise on takeoff.
And landing thanks to lithiumair batteries. Boeing and NASA could team to launch a hybrid commercial airliner called SUGAR for Subsonic UltraGreen, Aircraft Research, which uses twothirds less fuel than an equivalent sized aircraft from 2015. Travelling 10 slower, but using 70 less fuel than today's Boeing 737, the D8 Series Double Bubble's fuselage will provide 20 of its lift. By 2040, we could see the world's first hydrogen powered commercial flight. The hydrogen would be cryogenically frozen. EAD's Zero Emission High Supersonic Transport passenger jet, running on biofuel, could cut.
The more than 6,000 mile flight from Paris to Tokyo to just 230 minutes. Like a fighter jet on an aircraft carrier, commercial planes could be catapulted into the air, reducing the length of runways by onethird. As if they were a flock of migrating birds, more intelligent systems could allow aircraft on the same routes to selforganize into a flying patter, reducing wind drag and saving fuel. Six hydrogen engines, a rear engine that doubles as a wind turbine, and solar panels on its roof and wings will propel the zeroemission Progress Eagle, a tripledecker, 800passenger.
More Sun For Less Money
We are sort of on the frontier of solar energy research. So everybody wants more energy from the rooftops the way you do that is to have more efficient solar cells. A photon from the sun is a little pack of energy. It comes down, gets absorbed, that creates a packet of energy and the material. The key to this experiment is to design material that then splits that packet of energy into two separate packets that can then go on to generate two electrons. Finding a way to do that to make.
Material that can take one photon and turn it into two electrons that's the subject of our research. There's a lot of land that's required to make a solar farm. You make a more efficient solar cell, you can use less land and that would lower the overall cost of solar energy. A lot of solar energy research is concerned with one or two percent improvement that'll translate to hundreds of millions of dollars. Here in my research group you know you have to take a longer view, you're looking for not one or two percent, but twenty or.
Thirty percent improvement. Ten or twenty years from now, you'll be able to install something that will provide a factor of two or more energy because it's much more efficient. The societal goal of our research will be to someday have a better solar cell and instead of needing 10 acres maybe you only need six or seven acres for your solar farm. People ask me if I have hobbies and I have to say I don't really have hobbies other than my work and my scientific research. I'm lucky in the sense that my work is fun for me and I do find enjoyment of that.
SOLAR BOAT KANNADA 20MB.avi
This solar boat has been designed by LG in korea and made available through the department of physics in Pune university. this is a ready made kit. you need to assemble it. here is a solar panel with a toy motor and a worm gear. when you keep it out in the sun it rotates. once the shadow falls on the solar panel the motor stops. place the motor in its plastic casing and this is the solar panel. this is the body of the boat. these are the styro foam mounts, with a hole in the middle where the main axle will come. this is the pilot.
And this is the mount for the solar panel which can be adjusted. now place the motor along with the worm in position. place the solar panel on its mount which is adjustable. now place the steel axle with the gear in the middle and place two pedals on the ends. now this is the entire assembly of the solar boat. you can see that worm is with alignment with the gear. if the gear moves, both the pedals will move. this is the solar panel whose angle can be adjusted so as to orient it towards the sun. if you place the solar.
Boat in the sun, the solar panel will produce electricity which will run the motor, which will run the worm gear and gear in the middle will operate the pedals. when the shadow falls, the boat stops. now place the solar boat in a big tub of water. sun will fall on solar panel, the boat will run and the boat will go forward. when the solar panel comes under shadow, the boat stops. right now its turning, pedals are moving and boat is moving round and round. but as soon as the shadow falls on solar panel, the boat stops. its a nice.
Radiant House Raising The Roof
Today we installed the roof module onto Radiant House. We built the top module seperately from the rest of the house for two reasons. The first is that if it was all built as one piece it would be too tall to be put on trucks to be transported to Irvine. The second is that with the roof module on the ground we were able to install the solar panels with more ease. After the crane arrived we connected the cable to the eight lift points on the module and then lifted it into place. The team members were extremely excited because.
