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.
How to Install Solar Panels Tools for Installing Solar Energy System
Now let's get a look at the tools we'll need to safely install this job. Well, we've got a couple of noncontact AC and DC warning beepers here. We've got a AC wiggy that tests for voltages up to 600 volts on the AC side. We've got a standard digital volt home meter for various testing purposes, and the more standard tools razor knifes, screwdrivers, diagonal cutters, linesmen pliers for twisting wires, smaller pliers, and of course the wire stripper's always handy. I like to have a level just in case we're mounting some stuff.
And the things you may be able to do without are some of these large. Boy these are big, these are for making battery cables. If you've got the crimps you make your battery cable very professional. But they're kind of expensive, you can do without that for a home installed system. And then, of course, we're going to use some miscellaneous hardware to mount our rails to the roof. We'll have some screws and more crimps to get the batteries and other wiring completed, as well as possibly a little bit of spray paint just to touch up some of.
Antigeyser Testing Completed for SLS Liquid Oxygen Tank
Music So we were tasked with essentially loading the largest launch vehicle ever built by NASA in history safely with liquid oxygen. We started planning this test program about three years ago. We started by doing a water development test, and we learned a lot in that test. This is the first time we've built a test article just like this. It's very unique to any other LOX system on a launch vehicle ever built. It's different from Saturn, it's different from Delta, it's different than Shuttle. So there are a lot of unique things we.
Got to learn. Today was our twelfth day of testing. We have a total of around twenty test days for our entire test program. The test program was designed to make sure that we had all of the possibilities, all the variables enveloped. Things like ambient temperatures failure of bleed valves on the engines, failures of helium injection, facility failures where we lose supply of liquid oxygen. We've spent a lot of time in that realm and failing certain things that could fail, and making sure that we have the right control knobs on and in.
Place to maintain the system safety. The time line to fill a vehicle of this size is on the order of three or four hours. Once it's filled we'll sit for a number of hours, for things like waiting for the system to actually stabilize.waiting for astronauts to board and other subsystems to get ready. Once you get closer to launch time there's about a ten minute window where you go into your launch countdown and that's when you're closing off the subsystems from the facility. isolating them. So this test.
How Induction Cooking Works
Many of you may not be familiar with induction cooking, so let's review how induction works. Induction cooking is a two part system. The first part is a coil of copper wire like this one. When electric current is passed through the coil, it creates an electromagnetic field of energy. All by itself, nothing happens. The control flashes a letter F telling you that it failed to detect a pan. Electromagnetic energy is around us every day in the form of AM and FM radio, cell phones, wireless laptops, microwaves, infrared, and visible light.
The second part of this twopart system is the pan. Now you need to know that not all pans will work on an induction cooktop. Pans that are a hundred percent copper, hundred percent aluminum, or nonmagnetic stainless steel will not work. The bottom of the pan must have some iron content. The easiest way to tell if your pans have an iron base core is to use a magnet. If the magnet sticks to the bottom of the pan then that pan will work on your induction cooktop. The bottoms of many pans are of a sandwich construction like this one.
Often stainless steel inside and out but may have an aluminum core in the center. Those pains will work if the stainless steel is magnetic. Just check it with a magnet. Now let's see this in action. I'll place the pan on a cooktop with water in it and turn it on high. If this were a traditional radiant cooktop, the entire element would heat and the entire surface would glow red, but not with induction. The coil below the ceramic surface does not heat and will not glow. All the electromagnetic energy passes through.
AntiGeyser Testing for SLS Liquid Oxygen Feed System Underway
MUSIC as SLS, there are a lot of things you have to think about. The problem we plan to address is called geysering. One of the first things we have to get our arms around is how we load the vehicle with cryogenic propellants, and how we safely load the vehicle. Geysering happens whenever heat is entered into the system and a large bubble forms and it displaces liquid and allows that liquid to come crashing back down and cause a hammering effect on the system. And this hammering effect can damage the tank or.
The feed lines or other components. So we put together a fullscale test bed here at Marshall that simulates the LO2 feed system for core stage. We're utilizing test stand 4670 at Marshall. We've set a tank that Boeing procured, which is representative of the SLS height. And we have fullscale feed lines where we matched geometry to the SLS flight LOX feed system. We plan to mitigate the risk of geysering with circulation induced by helium injection. We've got two feed lines which feed four engines. The two feed lines.
Solar Electric Propulsion Aids CostEffective Space Exploration
Music Music The objective of the solar electric propulsion project is to enable or be a step change in solar electric propulsion. Right now it is used for station keeping for a lot of geo comm sats. What we are trying to do is take it a step further, and have this electric propulsion used as the primary propulsion for satellites. We need to make higher powered solar arrays that can power these higher powered thrusters. The issue with that is that you need them to be stowed for your launch vehicle and they need.
To be autonomously deployed. We also have support from folks at Glenn and Langley, supporting that work. Historically there was the NSTAR mission and DAWN and those were on the order of 2.5 kilowatts of electric propulsion. The advanced EHF was on the order of 10 kilowatts and that was where they utilized, and that was where they used electric propulsion in a manner it was not designed for. And it succeeded, it saved a billion dollar asset. What we are looking at is a 30 kilowatt SEP TDM. So this would be.
A step change from the current state of the art, with about a factor of 3 to then something that could support human exploration. And that is on the order of 100 kilowatts to 300 kilowatts. What exactly that is we don't know for sure because of the particular architectures are trading, but it is on the order of 100200 kilowatts for human exploration. So as far as compared to chemical propulsion, you don't need as much propellant and electric propulsion is much more efficient as well. We're utilizing power from the sun to power our.
Thrusters and also other onboard electronics. So we are utilizing, caching the suns power, with our arrays, using that to power our thrusters. So our tanks that we need to power our thrusters are zenon are much smaller than what you would utilize with chemical propulsion. So what that does it allows you to either send more payload or to use smaller launch vehicles. Both of which save you a lot of money because it costs so much to send things into space. There are 4 main objectives for the mission there's technology, technology.
Development, infusing new technology. There's capability, so having a new capability, a new system, an integrated system again which is the same. And extensibility, something that can be used for this TDM but infused for human missions but also for industry. So those would be our four objectives that we are gearing towards that this mission will be targeting. SEP can be applied to broad range of missions, it would range from science missions to human exploration missions, to DOD to satellite servicing to a plethora of industry opportunities. So there.

Are Electric or Gas Water Heaters More Efficient
Are electric or gas water heaters more efficient That is an interesting question you pose. Historically gas water heaters have been thought to be the most fuel efficient, however there are a number of electric water heaters that are also efficient. For instance the electric heat pump by Rheem, the Rheem 50 is one of the most efficient water heaters on the market. That is pretty interesting. What can you tell me about the difference between gas and electric water heaters in terms of efficiency Well, some of the differences between the two units are that obviously electric heaters.
Run on electricity. They consequently are at the mercy of a power outage. A power outage is one of the reasons that people may prefer natural gas heaters. It also depends on a large part where your power comes from and how much your utility costs per kilowatt hour. Some people in a certain locality may get greater fuel efficiency with their natural gas unit, while others may find that the electric units are the best in terms of overall efficiency. That is a point to consider, my electricity costs here are pretty expensive. I think I.
Might do better with a natural gas water heater. Even though usually gas heaters are cheaper to run overall, they are more expensive to purchase and can cost about one hundred dollars more than electric heaters. They also require venting which electric heaters do not. Your point, and you do have one, is that electric heaters cost less to purchase, and less to install, but they may be more costly overall. Exactly, you are a quick one. The most efficient water heaters are the tankless varieties, and the gas versions are the most efficient but they can cost up to $1,300.
