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. Students of Full Sail have handson access to technology on their first day, get a discounted laptop and all the software they'll need to earn degrees in software, mobile and web development.

Welcome to the Teeny Greeny my name is Rob Greenfield and this is my off the grid in the city tiny house life Last Fall I left my apartment to live a simpler life I left behind the convenience of living on the electrical grid it was all too easy for me to waste energy when I had a seemingly infinite supply at the flip of a switch or push of a button Here at the Teeny Greeny I harvest my energy from the sun with these solar panels I thought about getting a whole larger system.
So that I could charge large appliances but I decided I didn't really need that much electricity and I wanted to keep things simple I've got this 20watt panel from Goal Zero and this 36watt panel from Endless Sun Solar both of them charge a battery and can also charge devices directly too This gives me plenty of energy to charge my laptop Powerup the 3 watt light bulb in my house my bike lights and my headlamp and shave my beard Most of the things that take electricity have an electricity free alternative.
I use this oldschool press to make my orange juice I don't need a fridge because i buy dried goods and purchase small quantities of produce at a time Since I eat a planet based diet I don't have to worry about meat either and And I don't use a microwave because I cook from scratch and spend time with my food my stove uses propane I do my laundry off the grid too and hang it out to dry Instead of watching TV I spend my time outdoors or with my friends.
And I'm going to build a bicycle powered blender too I found that I just don't need much electricity at all and that my life is much more stressfree without all the electronic gagdets Also it's easier to produce all the energy I need with solar panels If I reduce my needs but my entire life isn't off the grid When I'm at a friends house of course I use the grid and I plug in my computer at the coffee shop or library One day, we'll all have renewable energy.
Solar array will allow OPP vehicles to operate at zero fuel cost
In conjunction with the Sustainability Institute, OPP and some student groups are building a solar array to offset the use of electric vehicles on campus. The people assembling the array are a mixture of OPP staff and tech service workers and student help. These tech service workers have really enjoyed coming out here for the day. They've worked all day helping the students, teaching them different methods of how to assemble things. I was jumping at the opportunity to do this as soon as I found out about it.
It's great to do something that's sustainable for the Penn State community and to learn something related to my major, hands on. As an energy engineer for the Penn State University I was driving around a V8 Ford Explorer getting three, four miles a gallon on campus and I thought that was a bit contradictory. So, I approached my boss and we went over a handful of things and came up with the idea of an electric car with a solar offset. The reason for that is, if you just get an electric car.
Can Korea take lead in Solar Panel Industry ,
Solar power is the biggest and fastest growing sector in the renewable energy market as it's expected to become an affordable and feasible alternative to fossil fuels. Korea is making increasing use of this energy source. but it is going to be a global player For this week's Industry Insight, here's Song Jisun. This is the biggest solar power plant in the capital that started operating this summer. It's equivalent to 13 football fields with a capacity of 5point6 megawatts enough for 22hundred households a year. Solar energy is quickly rising as the next.
Generation of renewable energy here in Korea accounting for 98 percent of all renewable power plants built in the first half this year. This solar panel system has been set up on the roof of this waterfiltering plant and we have completed a couple of other solar power facilities like this for the Seoul Metropolitan Government. It's fully operational even on cloudy days and only takes three months to install and operate. The market for these solar facilities is booming in Korea. with most being bulit by government or public agencies. Over the past decade. solar energy has emerged.
As the world's biggest source of renewable energy, overtaking wind power. Last year alone it created half of total electricity generated from renewable energy sources. This prospective market is forecast to expand by 10percent each year by 2030. with China and India likely accounting for half of the global demand. By then, the cost of generating electricity from solar power is expected to reach similar levels to burning fossil fuel meaning it could become more widespread without the support of government subsidies. as it mostly depends on at the moment.
The biggest competition in the industry comes from China which produces 80percent of the global demand. at prices 20 to 30 percent cheaper than Korea. Backed by government support, Chinese companies have been producing well over the market demand. with half of the world's top 10 solar panel producers based in China. It's not easy to counter them in terms of price, so Korean firms must improve their costefficiency, at the same time revving up quality and technology. Around 40 players are in Korea's solar power generating market with small and midsized.
Companies focusing on solar cells or modules. while large conglomerates aim to tackle the global market by equipping a complete chain of production to service. We've established a value chain from solar component production to system maintenance. And we aim to expand the solar power generation infrastructure to even include households. Industry experts point out that it is also crucial the government take steps to speed up growth of the domestic solar power industry. To expand its economy of scale and improve its profitability, they add. Korea needs to ease regulations concerning installation.
Power to the People with Johan NorbergPreview
JOHAN NORBERG Most people in developing countries aspire to a rich, better life. These people know how we in the West live, and they refuse to be left behind. The highest standard of living the world has ever known has been built on an everincreasing use of energy, and there is no end in sight. We've made great strides in making everything more energyefficient, from jumbo jets to television sets. But despite that, we've increased our use of energy. Not only do we fly more, but there's a TV on the back of.
The seat. Couldn't we all just cut back, and learn to live with less energy Why can't we live greener reduce our consumption buy local and just travel less Denmark wanted to maintain its high standard of living, and reduce dependence on fossil fuels. So it bet its future on wind power. Should we follow in their footsteps Or could massive solar, like this plant in Morocco, be the answer Some believe that Ethanol, as a biofuel, was going to help to solve our energy problems. Now it appears to be a dead end. But fracking, under these.
Same fields, is now creating a boom in natural gas, especially here in the United States. It's the cleanest burning fossil fuel we've got, and it seems we're finding more of it every day. But can we live with the tradeoffs The most ambitious transformation of a country's energy sector is taking place right now, here in Germany. The specter of potential nuclear disaster has moved Germany away from nuclear, and toward wind and solar energy but not without unintended consequences. Right now, we are relying heavily on fossil fuels, and a lot of people are concerned about global warming.
Turning Salt water into Drinking water using Solar power
According to the Securing Water for Food agency, between 2000 and 2050 water demand is expected to increase 55 percent globally, meaning the number of people affected by water scarcity will continue to grow. By 2025, twothirds of the world's population could be living in severe water stress conditions. Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water and much of that area is not served by an electric grid that could run conventional reverseosmosis desalination plants.
To find solution for this drinking water issue in developing countries, USAID the U.S. Agency for International Development had run a global competion for Desal prize. The idea for the competition was to create a system that could remove salt from water and meet three criteria it had to be costeffective, environmentally sustainable, and energy efficient. The winners of the $140,000 first prize were a group from MIT and Jain Irrigation Systems. The group came up with a method that uses solar panels to charge a bank of batteries. The batteries then power a system that removes salt from the water through electrodialysis,.
That means that dissolved salt particles, which have a slight electric charge, are drawn out of the water when a small electrical current is applied. Using the sun instead of fossil fuels to power a desalination plant isn't a totally new idea. Larger solar desalination plants are being seriously investigated in areas where water is becoming a scarce resource, including Chile and California.But the current technology is expensive. The MIT team's this new desalination technology electrodialysis is comparatively less expensive. Both electrodialysis and reverse osmosis require the use of membranes, but the membranes in.
