The solar industry is very, very focused on improving efficiency and reducing the cost. Our attempt here with this research is to propose a new way of looking at these structures and saying, well, you can use existing materials and nothing really needs to change very much. You just shape them in different ways that gives you this benefit. Kirigami is a Japanese art that's related to origami where origami is really about folding of things and kirigami is about cutting things. A colleague of mine who is an artist, Matthew Shlian, he had some interesting.
New shapes and when you pulled on the sheet of paper the cuts would sort of begin to buckle and deform in a very controlled way and so I realized at that point that we could look at that structure as a hyperminiaturized version of solar trackers. Conventional solar tracking has been used for many, many years. The mechanism itself cost quite a bit of extra money. What people end up doing as they say, well, since the mechanisms gonna cost all this extra money. we might as well put a really big panel and then eventually you end up with.
Something that's really big and really heavy. When you think about putting this type of thing on a rooftop it's very very difficult and in most cases is just purely impossible. It was a fairly lengthy process because the things that you do in paper don't automatically translate to other materials and so I started talking to my colleague, Stephen Forrest, about using some of their very high efficiency gallium arsenide solar cells. They're pretty thin, less than 2 microns thick that's ten to fifty times thinner than the thickness of a human hair. What the new design allows us.
To do in contrast to conventional tracking is it basically allows us to work with the same form factor. It doesn't catch the wind, it doesn't weigh any more than a conventional solar panel might and the thing that it buys you is that you can use less semiconductor to gather the same amount of energy. A third less material to generate the same total amount of energy that you would otherwise. Which means that in turn that I could decrease the cost of installation because there are fewer panels to install but you do require little bit of extra area. When you.
Multiply it by the total number of solar installations it's kind of like a billion dollar value proposition potentially. I guess it looks simple enough, kind of like something that you could do on your kitchen table, things don't have to be complicated for them to work. If this can be shown to be quite reliable, then the net benefit could be quite big. V.O. These candies which are already pretty soft should be about 10 to 100 times stiffer than the silicone. So the material that we're working with in the lab is really really soft.
Solarpowered color MconneX MichEpedia
Solar energy is the only energy source that we can rely on to survive in the future. We would like to maximize the utilization of solar energy so what we have achieved here is colored solar cells you know the red stripes the blue background they are actually working solar cells. You want this material semiconductor material to absorb all the light and that's why the traditional solar panel they look black. They probably can only be installed on the rooftop because nobody's going to put these black panels on the side of the building or windows.
The rooftop area is very limited, however they are huge amount of surface area on the side of the building not only the exterior but also be interior of a building. There are ambient light that we can harvest. You want a structure to be able to absorb this light but also as a decorative item. sounds of lab What differentiates our work from work in other labs around the world most of us Connor solar cells that produce color is because the material itself that is used in building the solar cell.
They are colored but the color will be depending on your viewing angle. So depending on whether you look at from the front or the sideway the color changes yeah for this type other decorative solar panel we wanted the color to be independent of your viewing angle so here we actually borrowed a new concept and that it has to do with very thin light absorbing semiconductor on top of a metal and that produce a special optical effect that allows us to make the solar panels that whose color doesn't change.
In our solar cell we actually go one step further we have two different versions one is semitransparent and it can be made in different colors as well and the other one is purely a reflective so you can make it into a picture you know for example we made a nice U of M logo. There is a tradeoff between the multifunctionality the solar cell have versus, you know, the highest efficiency one can achieve. The black solar cells absorb the whole spectrum. A colored solar cell for example it absorbs onethird.
Of the light right I'm passing the other light that I means that the solar cell efficiency maximum will be onethird of a black solar panel can produce but on the other hand by making this multifunctional I hope that it can expand the scope of applications rather than just the rooftop in a modern home we want a lot of things to be a beautiful by why not make it was on multifunctional, not only a decorative item but can also produce electric power. V.O, In a quantum computer we don't have bits of information we have something called a.
June Energy Portable solar panels
I was born and raised in Mali, West Africa from a low class family. i was born in Chittagong, Bangladesh which is the commercial capital but my father was from a very very poor village and a very poor family in Bangladesh Everything was pretty much limited. So it was tough growing up. Lack of energy everywhere. Students having no access to electricity I had to pretty much study under kerosene lamps and candlelight.... which are very harmful for the lungs and eyes as well. But I didn't have access to anything better. That was the only choice that I had.
What we have actually developed at June Energy is basically a handheld device that utilizes clean solar energy, stores it in a battery and provides light at night through cleanlighting LEDs. It also has a port on the side where you can actually plug in your any cell phone that you have and it will actually help charge your cell phone so people at nighttime can talk and keep in touch with family back in their villages. Kerosene lamps if you look at it, provides sixty lumens of light which is really not much, that's why it strains the eyes. Whereas our product, we're looking at.
Maybe giving sufficient lighting above a hundred lumens which is really ample for reading at nighttime and provides a good surface area so students can read. Currently we're in a a final revision of our beta product. On my business card. my role in June Energy is, I'm the chief technical officer but we're pretty much, everyone does everything, so I guess it's kind of a loose title. We've build a fully functional prototype and we've done a rapid prototype for the mechanical design of it and now we're just working on getting cost down actually. Our target price for our.
Target customers, which are the people in these developing areas, is around $15 or so. We were traveling back and forth to the Ross Business School, meeting MBA students from there, we went to the medical school. We talked to the health officials who told us, 'you know this energy problem It's in health care, too, because hospitals in rural areas of Africa can't operate at night because we have no lighting.' Our initial market might be like Engineers Without Borders or Peace Corps volunteers, the military is a possibility. Anywhere, any type of situation where you're in an area without electricity.
In a remote area like hiking trips and things like that. I'm really excited about our upcoming venture in Singapore, to get more involved with the manufacturing process. So our next step is to make a second trip to Africa We're definitely going to go to Kenya in the next one to two months to understand how people live there, what are the problems their really facing, and how our solution can meet and be tailored to solve their problems. I'm excited already because I think the dream is coming into reality.
As of a couple weeks ago we just were offered just over half a million dollars of venture capital investment So we're really excited about that as well. Since I was a eleven, I've had that mentality I want to do engineering and so i can give something back to the society. It's about helping people. I'm not happy with the way other people are living. Like, I see things that are happening and I'm, I don't I don't think they should live that way, you know So it's just, making a stride toward changing that.

Block Ms in a Cancer Fight
These particles are about a thousand times smaller than the width of a hair. I estimate we could fit billions within the big Block M behind me. We just wanted to demonstrate that we can make particles in different complex shapes and we just wanted to show Block M as an example. So these are the particles floating on water now. I think we made,probably, the world's smallest Block M particles, in any case, we haven't seen anything smaller than these. Block M was obviously one of our favorite particles to make.
We've also made all sorts of other shapes from squares and triangles to star shaped particles a range of different shapes. One of the primary applications is in the area of drug delivery where there's been a lot of work looking at how shapes of different particles can affect whether a cell can uptake those particles or not. We've been looking at drugs that can specifically go in and target ovarian cancer cells and kill the harmful cancer cells without affecting any of the remaining cells within the body. By knowing which types of shapes can actually pass through a particular cell.
Membrane we can be easily develop the exact same shape and then incorporate drug molecules within that particle so that once it's ingested by the cell it can go in and the drug can be released on the inside of the cell, essentially killing that particular cell. The process of making these particles is relatively straightforward we take a template that has a very low surface energy, essentially it's not wettable by any liquid and in between we pattern domains that are extremely wettable by other liquids. So, with this technique I start out with a silicon wafer coated with liquid.
Or plain coating and then I expose this wafer to UV light. To expose that in the desired patterns we use a photo mask and we design the photo mask depending upon the particle shape and size that we want. We dip this template in different polymer solutions one after another. This allows us to deposit different layers of polymers one on top of another. There's no limit really to how many different layers you can have in a single particle based on this technique. Imagine I had to take a drug.
Every day for 10 days, if I had 10 layers within a single particle I could take a single capsule and have the particles dissociate over 10 days each day releasing a certain amount of the drug and so you would only have to remember to take the pill once in 10 days as opposed to every day for 10 days. The other thing that it's really useful for is developing particles that can be targeted to specific areas so, for example, we've incorporated magnetic particles and so using an external magnet you can program are you can direct.
The flow of these particles to any specific areas within the body that you would want. No one had really put two and two together and combined these properties of using a very low surface energy material and a high surface energy template on top of it to make particles before us. In terms of next steps for the project, we're working on developing a tool that can be used to automate the entire process where we'd be essentially able to program and both the shape size and thickness and we would be able to make those in a very rapid and automated manner.
Residents At Huntington Beach Apartment Complex Lose Ceilings After Heavy Rains

Garden Gurus Solahart Power Solutions
This gardening program tends to tackle issues related to the environment, we even try and save your back along the way. Well this stories is going to help you do both in a really big way. Now, with power prices skyrocketing we need to look at sustainable free energy sources and that's why solar power is so important Without the Sun life wouldn't exist and the reason we have seasons is because the constant bombardment the Suns warming rise and our Earth's axis. Energy's absolutely essential for our survival to, and considering we all live under rooftops, why not use solar energy to power our homes.
Solahart has long been recognized as a leader in solar technology and for sixty years now Solahart solar water heaters have been saving Australians much as 50 to 90 off their hot water energy use. And now they're leaders in PV, or photovoltaic, energy production. The way PV works is simple yet absolutely effective. Rooftop panels harness light from the Sun which is converted into electricity of sitting your electricity costs any ex's pal can then be sold back into the grid soul has been very cautious when entering this market.
As a quality systems can be reach a medically this cells are individually tested and then selected to make soul has high standards and technical specifications the cells are independently rated as one of the hospital Ming saw Lindsay collecting performance panels there are a few things that you need to take into account when it comes to setting up a photovoltaic system on your oath now an onsite assessment make sure you pick the raw aspect for example if you're in a north facing side you got to get the.
Best results and is with the free onsite assessment from Seoul hot really comes into play see it helps you picked a lot system to your situation once you're happy delving organize the installation using a fully qualified professional installer remember how prices are skyrocketing we'll have to do something to reduce our energy bills so why not use the sundries now they're still government rebates available and Seoul hot have some right finance packages 10 it uses the sun's energy to get you off that neverending price hike cycle it's an investment in your future that will reach you should have bills and.
