This episode of DNews is brought to you by Full Sail University. This week the Japanese Aerospace Exploration Agency announced it wants to get solar power from space. I'm having flashbacks to disasters from SimCity2000. Hello! I'm Trace. Thank you for watching DNews. Back in the 1960s, American aerospace engineer Peter Glaser proposed launching solar panels into space, and beaming the power they collect back to the surface for our use. Since the late 60s the idea has been in a holding pattern mainly because of the expense and worries about maintenance and equipment, but thanks.
To recent developments in solar panel tech the Japanese space firm JAXA says they can finally try it. The plan is ambitious at minimum and cost hasn't yet been calculated, BUT JAXA is determined, and they're not the only ones. The U.S. Naval Research Laboratory is also interested in spacebased solar. The reason everyone's looking up, is because that's where the sun sits! If we can put a satellite in orbit to collect the sun's rays BEFORE the atmosphere filters them out, and without the worry of a cloudy day, that would be rad. The JAXA Space Based Power System.
Or SBPS will orbit 22,400 miles up, and if done to their specs, would completely replace a nuclear power plant by producing 1 gigawatt of electricity enough to power halfamillion homes. Their plan uses a 10,000 metric ton system, which is. well pretty ridiculous. The largest rocket ever launched was the Saturn V it took our boys to the moon and could only lift about 130 metric tons. Once the power is gathered, a converter in space will convert the electricity into a microwave beam not like in your house, literally waves of energy that are.
On the micro scale. Microwaves can be converted from energy at 80 percent efficiency, which means there would be some loss, but it would be pretty damn efficient about 48 of the power collected would reach consumers. Which doesn't sound great, but it really is. To make sure the array is getting sunlight 24hours a day, JAXA plans to put mirrors on either side of the planet to reflect sunlight at the collector all the time. The Japanese are announcing their plan so far in advance in the hope other countries.
Will gather and help realize the dream of solar from space. Once created, it could provide clean, unlimited energy anywhere on the planet, regardless of remote location. Here's the kicker. It would cost about a trillion dollars. Which sounds like a lot, but it's like 125 bucks per person on the planet in 2030. And that's WAY more than you're paying doe your power bill. Not to mention oil wars and all the pollution, ecological damage, mining and drilling that goes with fossil fuels. We've got commenting areaaassss, check them out and type your feelings on spacebased.
Solar so we can all talk about it! None of this would be possible without computers to run the system, and we need people to write the computer programs. Full Sail University in Florida offers courses to help train tech professionals by blending code and realworld experience.

How Do We See Things From Space
Earth observation satellites orbit between 111 miles and 1,243 miles above the surface. so HOW THE HECK can they spot the car in my driveway! Hey y'all, Trace here for your Weekly DNews Space Update! There's this amazing political commitment called the International Charter on Space and Major Disasters. The Charter was created after the UNISPACE III conference in 1999 as a framework for sharing of satellite data amongst member states in the case of disaster. Pretty much all of the satellite operating countries are members. China activated The Charter after the Malaysian Airlines Boeing.
777 disappeared. Once activated, member agencies determine which satellites can be tasked with shooting pictures of the area of interest, usually a location of a tsunami, earthquake and so on. This is the first time the Charter's been activated to hunt track down a missing airliner! Conspiracy theorists assume spy satellites can zoom in and read over your shoulder, but the Earth is real big y'all. Anyone who's used Google Earth knows this, you can spend days on there. But how does a thing 1200 miles a way make out a tiny airplane, or a car in.
My driveway Back in the day, the recently declassified Gambit and Hexagon American spy satellites used large format film dropped from space and developed on the ground. The chemical process of film is SUPER clear, but limited to the number of rolls of film blasted off with the satellite. Digital camera technology exists in part BECAUSE of the space program's want for digital images. Three companies GeoEye, DigitalGlobe and Spot Image employ about a dozen satellites just for ground imaging. Governments, agencies and private companies have their own cameraequipped satellites, but the specs are a secret. The GeoEye1 says.
They can capture 700million pixelspersecond with a black and white resolution of 16 inches per pixel. The most famous, Earthimaging satellites are the Keyhole series. They're probably the best, and some version has been orbiting for more than three decades. The KH satellite is basically a giant orbiting lens. They're like the Hubble Telescope, but instead of pointing at faraway galaxies, they're pointing at terrorists, enemies of the state, and that little red book you're reading in the park. HowStuffWorks says the KH series can use it's camera to see things as small as FIVE INCHES per pixel, so they can't tell WHAT book you're.
Reading, but they can see the book. When it comes to spotting VERY specific things, things get tough. The lenses and digital cameras inside the satellites have to point at the right place at the right time. So if you're worried someone is spying on you, don't be. The resources are hard enough to task already. Not to mention, all this doesn't mean JACK SQUAT without some SERIOUS data analysis. There are whole industries built around the analysis of the images and data from space. Think about it 700 megapixels every second is a lot of visual information, and computers.
Aren't great at picking out visual details. With regard to the Malaysia airline, NASA is looking through the archives of their satellite data to see if any equipment was over the area at relevant time. China's satellites spotted some debris on Sunday, but small pieces of debris in a constantly moving ocean are difficult to identify. So far no one has found anything. The Internet has been a game changer for this type of humancentric analysis. DigitalGlobe has made it's entire library of relevant photos available to help search for the missing airplane,.
What Is A Solar Sail
I'm Fraser Cain, and I'm a sailor. Well, okay, I've got a sailboat that I take out on the water when its warm and the weather's nice here on Vancouver Island. I think it's one of the reasons I absolutely love the idea of a solar sail. Here's how they work Light is made up of photons. Even though they have no mass at rest, they have momentum when they're moving, well, light speed. When they reflect off a surface, like a mirror or a shiny piece of metal, they impart some of this momentum to.
That surface. This effect is negligible here on Earth, but out in space, with forces perfectly in balance, that additional momentum can really add up. A spacecraft flying to Mars gets pushed off course by several thousand kilometers because of light pressure from the Sun.If mission planners didn't compensate for this drift, their spacecraft would miss the planet, or even worse, crash into it. Even though the total amount of pressure per square meter on a solar sail is minuscule, it's constantly streaming from the Sun, and it's totally free.And propulsion that you don't have to carry with.
You is the best kind there is. This is more than just an idea. Solar sails have already been launched and deployed in space. The Japanese Ikaros satellite unfurled a 14meter solar sail back in 2010. NASA launched its own NanosailD spacecraft in 2011. An even bigger solar sail, the Sunjammer, is planned for launch in 2014. The Planetary Society is working on a solar sail project as well. The closer to the Sun you are, the better they work. In fact, a solar sail would be an ideal vehicle to explore the regions of Mercury and Venus, since they receive so much.
Radiation. But you're probably wondering how a solar sail could get down to those planets because light is streaming from the Sun in all directions. It's all about raising and lowering your orbit. If you want to raise your orbit around an object, all you have to do is speed up. And if you want to lower your orbit, you just need to slow down. A solar sail launched from Earth would start out with the same orbital velocity around the Sun as the Earth. To get into a higher orbit, it tilts the sail so that the light.
From the Sun speeds it up. And to get into a lower orbit, it tilts in the opposite direction, and the light from the Sun acts like a brake. A solar sail might even be the ideal spacecraft to make the journey to another star. An interstellar solar sail could lower its orbit so that it's just above the surface of the Sun. Then, it would unfurl the full sail and capture the most possible photons. A series of powerful laser beams would then target the sail and increase its velocity to a significant fraction.
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.
Which Solar Panels to Use
Namaste Solar primarily installs from three manufacturers SunPower, Sharp and Kyocera. Your Sunpower panel and your Sanyo are you two high efficiency high end panels, so must power per square foot but also the most cost per watt as well. Those panels are very popular when you have very limited roof space and you want to maximize how much power you get on your roof. Sunpower also has the nice added benefit of an all black ascetic that you don't get with any other panels and that is really popular with homeowners.
Then your Sharp and Kyocera panels are your low efficiency but lower cost panels so those can really make sense when you have a lot of roof space in order to fit the solar system. So which one has the most bank for the buck Sharp or the Kyocera They are actually quite comparable, Sharp has their own racking system now, which is called SRS aestecally is nice because black frame system which sits low to the roof but sometimes you do not get the flexiblity with that system because of the low profile and.
Because it is a frame you need to have some margin of roof space around the system to work so you end up losing a little bit of real estate with that system that you can't go over attic vents and those kinds of things. Where as with a panel like Kyocera can be used with standard 3rd party mounting systems such as Unirack or ProSolar and those tend to be pretty flexible and can often clear some roof obstructions and go right to the ridge of the roof or gutter of the roof.
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.
