We install our gas boosted solar hot water system. The collector panels are mounted on the garage roof directly above the storage tank. The gas booster is adjustable so we can fine tune the hot water supply to maximise its efficiency. Getting the temperature right means you don't have to mix in too much cold water. Once it is up and running, the system is bled and we are ready to roll. The panels are on the north face of the house and angled at about 9 degrees. Because we are installing the storage tank inside the garage it will need to be flumed out into.
The atmosphere to comply with safety regulations. This is part of our gas boosted hot water system installation. It's called the water guardian and what it does, when you turn on the hot tap instead of allowing the cold water to run out first before the hot water arrives it recycles it back into the storage tank. Just press the button, it comes on we wait for it to stop There we are, piping hot water strait away. This device saves 16000 litres of water per annum per outlet. Worth doing.
Saving Energy with Solar Power Using Homemade Solar Panels
When you look over there you see the more common size of solar panel. Don't be afraid that it looks that terrible because I did that solder it together by myself. There are companies who are producing these full sized cells and sometimes when they produce them, they break. And that what you see here, these pieces are all broken. And the funny thing is that it doesn't matter if they are broken or not, they are still producing electricity and each of these pieces is producing 1.5 volts. And the wattage depends on the size.
So this one will produce much more watt than a small one or a broken one. And so you see what I did is here is just put them together. The sun shines on it and ions go through this silicon. So on the top you have minus and on the bottom you have plus. And so I grab the plus from the bottom and bring it here to the next one so this is then the first 1.5 volts. It comes here, feeds in here. The next one has 3 volts. So it goes back there,.
Solar powered air conditioning
Music playing Narrator Over 50 percent of the greenhouse gas emissions you produce in your home are generated by heating, air conditioning and hot water. In other words keeping your home warm in winter, cool in summer with nice hot water on tap is emitting 2.5 to 5 tonnes of greenhouse gas emissions each year. It also contributes a hefty amount to your electricity bill, between 50 to 60 percent. CSIRO has invented a new solar air conditioning system for Australian homes. This technology solution will reduce Australia's emissions, reduce your energy.
Bills and reduce our demand for electricity and gas. If every home in Australia installed our solar cooling technology it would be the equivalent of saving 15 mega tonnes of CO2 or taking 3.5 million cars off the road. CSIRO's solar air conditioning is an innovative three in one technology that provides hot water, cooling and heating. It uses only a fraction of the electricity of current systems and halves greenhouse gas emissions. The process begins with a typical solar hot water system. Water is heated by solar panels and stored in the hot water tank.
This solar hot water can then be used throughout the home, reducing the need for gas or electricity. A portion of the hot water is diverted into CSIRO's new solar air conditioning unit, which is divided into two compartments. The hot water enters a heat exchanger in the first compartment of the unit. Similar to a car radiator the heat exchanger uses the hot water to heat outside air that has been drawn into the first compartment through the vent. At the same time outside air is also being drawn into the second compartment into a desiccant wheel.
The desiccant wheel is the most critical part of the system. It is used to dry out the air before it goes into the house. Slowly turning the desiccant material in the wheel continuously absorbs moisture in the second compartment and then the absorbent material dries out in the first compartment. The desiccant material is dried out using the hot dry air generated by the heat exchanger. This air is then exhausted outside the home. The dry air from the desiccant wheel flows through an indirect evaporative cooler which creates a stream of cool dry air.
Okapi Fan Control Systems for Solar Collector Air Heaters
These are two 4' x 8' solar air heater panels They only took a few days of work and cost under CA$400 to make The sun shines on the panels on a cold December day But there's a problem. Due to convection, all the heating occurs at the ceiling Which this thermal image clearly confirms If you direct the hot air from the panels to the floor, furniture and other objects You will more efficiently heat the room We solved this problem by using our innovative fan control system After just a couple of hours of solar heating.
How to Install Solar Panels Solar Energy System Sizes
Now, we'll talk a little bit about the sizing of these systems. It depends on what you want to actually run, and of course how much money you have. We're going to go on the smaller side, just today. If you're trying to power your whole house, and you had air conditioning, and stoves, and lighting, and computers, and the normal things a normal house has, and you wanted to run it all by solar, you'd be using quite a few of these, or these, and some of the systems we install have up to seventy panels or more, and unfortunately,.
They're maybe a thousand dollars each, so you can see the price goes up, with the amount of load you wish to take over. In our system here, my plan is to take my home office off the grid, and just power up some laptops, and entertainment equipment, so we're going to be using a fairly small system. One or two of these hundred and forty watt panels, charging a bank of perhaps four six volt batteries, and that will give us enough power to run quite a few lights, my laptop, and some entertainment equipment, from the power of the sun.
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.
