Hey everyone, went to Big Lots a couple of days ago and they had their Christmas lights on sale so I took the opportunity to get some their solar LED Christmas lights. Normally $18 for $9 I thought it was a fairly decent deal. So what it comes with is, there is a solar panel here the lights themselves they're sixty to a strand and they just connect right into the panel there's a notch in there so it only goes in one way and this will tighten I assumed to keep the rain out since they are designed for outdoor use.
They also give you a clamp so you could actually attach it to just about anything that it will clamp onto, I assume a rain gutter would be the most common they also give you the yard stakes this one looks like it plugged in to there and the solar panel plugged into there so they give you a lot of options so you can get it just about anywhere that there is sun the panel itself has a on off switch in the back here it looks like a sensor for whether it's daytime or nighttime.
Looked like two AA batteries that are rechargeable on the inside, I didn't take it apart or anything to look to give you an idea how bright the lights are that's the lights and in comparison, they had these lights that plug in. These are the warm lights, they seem to flicker in the camera uh. these were $1.50 since they were 50 off. Normally $3, 20 to a strand. these seem to use about 1.61.7 watts of power so they should last quite awhile if you run them off battery or not eat up the.
Electric bill as much. According to the box they use 90 less power than normal Christmas lights Actually on the back of the box of the solar one it gives you a little comparison. I assume that 600 of this C7 lights about $100, $94.50 cost for 45 days 7 hours a day with the average cost being 10 cents per kilowatt hour. And the 600 mini lights would be $7.71 but the solar one ends up being free because it uses the power from the sun. No idea who makes it, just says distributed by Big Lots and made in China no actual manufacturer.
Plants vs Solar Panels Which is better at capturing solar energy AtBristol Science Centre
This is an aquatic plant called pondweed, and we can see that it's making tiny bubbles of gas. This gas is oxygen and all plants produce it in a process called photosynthesis. The word photosynthesis comes from the Greek meaning light' and putting together'. Plants use the energy in sunlight to make sugars, out of the simple ingredients of carbon dioxide and water. And do you remember those bubbles of gas we saw earlier Well. deep breath they're pretty useful. To make the sugar, or glucose, the bonds which hold the molecules together.
Have to be broken apart and rearranged. The bonds are made of electrons. So the water needs to lose electrons, and the carbon dioxide has to gain electrons. And the colour of leaves gives us a clue to what is responsible for this rearrangement of electrons. Every leaf cell contains a pigment called chlorophyll'. It's the chlorophyll which makes the leaves green and helps make photosynthesis happen. Chlorophyll has the amazing ability to release electrons when exposed to sunlight. The electrons from the chlorophyll are replaced by splitting apart water into ions of hydrogen and oxygen.
The excess oxygen is then released into the air. The flow of electrons from the chlorophyll is then used with the remaining hydrogen ions to produce the energy needed to synthesise glucose from molecules of carbon dioxide. So sunlight provides the energy we need to move electrons from one molecule to another turning light energy into chemical energy ready for our plant to use. But can we do the same thing artificially How does photosynthesis compare to a solar panel Well, solar panels like those on the Energy Tree.
Use light as an energy source, and they also generate a flow of electrons. But they don't store chemical energy they convert light energy into electrical energy. They do this by using something called the photoelectric effect'. When photons come and hit a metal surface, they knock off electrons. We then capture and store these electrons. These photovoltaic cells are made of a silicon crystal. But silicon is a poor conductor of electricity. So impurities are added to help. This creates something called a 'semiconductor'. As light hits the surface, electrons are knocked loose.
The electrons then flow from areas with a high concentration, to areas with a low concentration. It's this flow of electrons which generates an electric current. We've done this on a big scale on our roof. We have 560 square metres of solar panels, which generate 47,000 kilowatt hours of electricity per year. So which is better, leaves or solar panels How efficient is each system at transforming the energy from sunlight Well, a leaf can turn only three percent of light energy hitting its surface into chemical energy through photosynthesis.
Whereas, a solar panel of the same area can turn roughly ten percent of the light energy into electrical energy that's over three times more efficient! But it's not quite as simple as that. There's all sorts of other things to take into account as well. Such as the time of day, the location, types of plant, and transport and storage costs on the other side as well. Solar panels may be able to absorb more wavelengths of light than leaves, but leaves can grow and repair when damaged. The Energy Tree may be able to charge your phone,.

Burning Stuff With 2000F Solar Power!!
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.

SOLAR BOAT ENGLISH 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.
