Tamo news presents solar power trainer shine future solar panels may be able to generate power scientists in China are
00:00:15
producing solar panels that can produce energy from the last source you’d expect when we’re talking about solar energy
00:00:21
rainwater in a typical solar panel photons from a light source knock electrons free from atoms within the
00:00:27
panel and the action generates a flow of electricity although solar power technology has been
00:00:33
getting increasingly efficient there’s still the tiny problem that solar cells can’t produce any power when it’s
00:00:38
raining researchers are introducing a new type of solar panel by adding a layer of graphene or carbon atoms
00:00:45
arranged in a honeycomb structure to dye sensitized solar cells a flexible layer of indium tin oxide in plastic is
00:00:52
included underneath graphene as unusual properties that allow electrons to move freely throughout the entire layer rain
00:00:59
water contains positively charged ions like ammonium calcium and sodium when water binds to the panel surface a
00:01:06
double layer of positive ions and negatively charged electrons is created which ends up producing a voltage and
00:01:11
current tests of the new solar panels have been able to produce hundreds of micro volts which is small even compared
00:01:18
to a standard double-a battery so there’s a long way to go before the new solar panels they come more widely used
00:01:24
but more efficient future versions could mean big things for the solar industry China powers on world’s largest floating
00:01:33
solar farm China just flipped the on switch on their latest green energy project a new floating solar farm
00:01:41
constructed on a lake and whinin city in central China is said to be the largest in the world it is made up of 160,000
00:01:49
solar panels these panels can produce electricity for up to 15,000 homes the farm is connected to a city where some
00:01:57
two and a half million people reside the panels are placed at varying depths over the lake the water helps cool the
00:02:04
electronics in the devices and stops them from overheating solar energy like wind is sporadic and environmentally
00:02:12
dependent meaning the amount of power panels can gather may sometimes fluctuate depending on the weather

Tesla gets into the home energy game Tesla has unveiled a solar roof product that doesn’t distract from the
00:02:29
aesthetics of a home as they look just like ordinary tiles each Tesla roof tile is made up of a solar cell quartz glass
00:02:36
and a color louver film that makes it appear opaque from an angle Tesla CEO Elon Musk said the tiles have 98% of the
00:02:45
efficiency of traditional solar panels however the tiles have the potential to go above normal efficiency if improved
00:02:52
coatings can trap light inside to reduce loss of energy Tesla sees the solar roofs working in
00:02:58
tandem with its power wall battery unit to provide energy for homes and it’s electric vehicles
00:03:04
Tesla unveiled four types of solar tile during a launch event at the Desperate Housewives said at Universal Studios
00:03:11
last Friday the tiles will be available next year through Solar City a solar installation company chaired by Elon
00:03:18
Musk which he’s trying to merge with Tesla musk didn’t reveal any specific prices
00:03:23
but said the Tesla panels would cost less than the full cost of a roof with the added benefit of being able to

generate electricity dragonflies can be used to spy on you scientists have created a technology that can turn
00:03:39
flying insects into surveillance drones the technology makes use of a tiny backpack equipped with solar power and
00:03:46
navigation systems the backpack is fitted onto a dragonfly and commands the insect with optogenetics a biological
00:03:54
technique that uses light to control the steering neurons inside the insects nerve cord dragonflies can then be
00:04:02
turned into tiny surveillance systems the same setup can be applied to other insects of a similar size such as
00:04:08
honeybees other applications of this technology may include guided pollination payload delivery and

precision medicine and diagnostics the great American Eclipse will cause massive energy loss
00:04:23
the Eclipse is just around the corner and while many are excited the astronomical event will also lead to
00:04:28
a gigantic dip in solar energy production the great american eclipse may cause a loss in solar energy
00:04:35
production enough to power some seven million homes according to US government data california provides 40% of the
00:04:43
solar energy in the US the state will see its solar power generation capacity reduced by 70 percent between 902 a.m.
00:04:51
and 1154 a.m. local time on the day of the Eclipse to fill the power gap during this time Solar reliant grids may turn
00:04:59
to natural gas or hydro plants for energy the Eclipse is set to take place on August 21st 2017 in the u.s. France

a new way of getting power from the Sun researchers in Britain have developed a new type of technology that can help
00:06:38
buildings to harvest solar power in addition to the power generated by rooftop solar panels solar squared glass
00:06:45
blocks contain a layer of small solar cells the intelligent optics of the blocks focus incoming sunlight onto the
00:06:52
solar cells when placed vertically the blocks can be linked and wired to one another generating power for buildings
00:06:59
and electric vehicles or to be stored in batteries these blocks can be embedded in conventional construction designs
00:07:06
tinting can also be added to prevent too much sunlight from entering the building’s interior researchers say the
00:07:12
blocks also offer better thermal insulation and traditional glass building materials startup company build

solar which developed this project is looking for test sites for this technology a finished product is
00:07:24
expected to be available next year Dutch University aims to use solar panels as highway noise barriers
00:07:35
Eindhoven University of Technology is developing solar panels that could be used to accomplish goals beyond
00:07:41
electricity generation such as acting as noise barriers along highways the practical test is being run along the
00:07:47
Netherlands a2 highway one of the nation’s busiest near the city of day involves sound barriers with
00:07:53
incorporated lscs for luminescent solar concentrators can absorb sunlight by using transparent diet plastic sheets
00:08:00
which then emit indirect concentrated radiation along solar cells hidden inside the frames the lscs can come in a
00:08:07
variety of colors making highways more visually appealing the current test features only two noise barriers which
00:08:13
measure 4.5 meters high by 5 metres wide a single kilometre of barriers could generate enough electricity to power 50
00:08:21
households the two sets of panels will stay alongside the a2 highway until early summer of 2016 as a full year of
00:08:28
testing is crucial in order to verify the durability performance of the panels under all weather conditions

quantum dot coding can turn windows into solar panels researchers of the Los Alamos National Laboratory in New Mexico
00:08:44
have developed a film of quantum dots that can turn windows into photovoltaic systems when sunlight hits conventional
00:08:51
silicon solar panels electrons break free of the top layer of semiconducting material the electrons then follow
00:08:58
conductors between the positive and negative sides of the panel to generate an electrical current quantum dots which
00:09:05
have an inner core and outer shell and a silica coat can be used as semiconductors quantum dots can be
00:09:13
spread into thin sheets that are placed onto glass window panes when photons from sunlight hit a quantum dot it
00:09:19
excites the electron in the valence band and sends it into the conduction band leaving a hole behind when the electron
00:09:27
recombines with the hole in the valence band a new photon with lower energy is generated this new photon then
00:09:35
propagates within the glass via internal reflections energy is generated when the propagating photons reach the windows
00:09:42
frame where solar cells are stored coatings of quantum dots can be used on any window to turn them into harvesters
00:09:50
of sunlight at lower cost than is currently available Los Alamos based startup ubiquitous quantum dots has
00:09:57
received a 225,000 US dollar grant from the National Science Foundation to commercialize this technology as a
00:10:03
coating on windows new solar sunglasses harvest solar power researchers in Germany have successfully
00:10:13
developed a pair of sunglasses that can generate power the sunglasses contain organic solar cells which are flexible
00:10:20
and can be made into a variety of shapes and colors the frames are also equipped with electronics including a
00:10:26
microprocessor two sensors and two displays the solar power captured by the lenses are used to run the electronics
00:10:34
which measure current illumination intensity and ambient temperatures that are displayed on bar graphs the lenses
00:10:41
can generate about 200 mil Alexa’s power which is enough to run devices such as a step counter hearing aid or a small
00:10:48
speaker the solar sunglasses work best in direct sunlight but they can also work in dimmer lighting environments
00:10:54
such as inside homes or at the office the researchers say the technology could be applied to the glass facades of
00:11:01
high-rise buildings such a large surface area would enable the new solar cells to generate significantly more power North

Carolina town fears solar farm will suck up all the sun’s energy a North Carolina town has rejected a proposal to allow a
00:11:16
solar farm to be constructed after residents expressed fears the panel’s would suck away sunlight from the town
00:11:22
solar companies are looking to the town of woodland because it’s located near an electrical substation where power
00:11:28
generated from panels could be fed into the grid during the public comment period before the rezoning vote was held
00:11:34
town residents voiced their distrust and fear of solar panels June man a retired Northampton science teacher is worried
00:11:43
that vegetation near the proposed solar panels won’t get enough light for photosynthesis man also said she was
00:11:49
worried about the high number of cancer deaths in the area saying no one could tell her that solar panels didn’t cause
00:11:55
cancer Bobby Mann said the solar farms would suck up all the energy from the Sun and businesses would not come to
00:12:01
Woodland [Music] the solar company then attempted to
00:12:06
address the council and audience but that didn’t go so well the council voted three to one against the rezoning and
00:12:16
later voted for a moratorium on future solar farms endless energy with one coat of paint researchers from the Royal
00:12:27
Melbourne Institute of Technology have invented a novel new paint that can turn surfaces into a hydrogen power generator
00:12:34
synthetic molybdenum sulfide is a newly developed compound that absorbs moisture and accelerates the splitting of water
00:12:40
molecules when mixed with titanium oxide in paint the resulting substance is able to produce hydrogen energy from sunlight
00:12:48
and water vapour hydrogen is one of the cleanest sources of energy and can be used to power vehicles and equipment the
00:12:58
solar paint can generate hydrogen energy in remote locations or hot and dry climates so long as there is sunlight
00:13:05
and moisture in the air [Music] researchers believe it will take at
00:13:10
least five years to come up with the final product but they’re confident that it will be cheap and accessible say no

green sources solar window blinds can block and harvest sunlight a California startup has designed window blinds with
00:13:34
solar panels that can block out sunlight while harvesting solar energy from it each slat in solar window blinds is
00:13:41
equipped with monocrystalline solar panels which can harvest solar energy the blinds can also track the path of
00:13:49
the sun’s position and automatically change the angle of the slides to optimize its absorption of sunlight the
00:13:56
company claims the blinds are able to generate up to a hundred watt hours of energy for every square meter when
00:14:01
mounted on the outside of a window or half that amount when mounted inside although the slats can automatically
00:14:08
change their angles the blinds can also be manually controlled via an app the company is hoping to raise $50,000 from
00:14:15
