Make a work of art using the sun as your pen with FEBO by Caitlyn


When you think of making art, you’ll likely use a pen, pencil, or paintbrush to make your creative mark. Different tools produce different results, and if you’re avid enough in your artistic pursuits, then you likely notice and appreciate the various intricacies and approaches to each medium. Lots of modern art is very reliant on how it was made, such as the blank canvas that has 1,000 hours of a man staring at it.
While that isn’t everyone’s gig, making art powered by the sun would certainly be a neat concept. The FEBO will allow you to do this, as its job is to focus the sun and turn it into a drawing implement that will let you freehand or follow a traced piece of art. Obviously you can use any type of canvas, though you’ll want to be smart about what you choose to direct some insanely hot rays of sunlight at.
There’s no ink, graphite, or batteries that you’ll need to replenish over time, as you only need a sunny day to create new work. You will definitely need to wear sunglasses when using this, as focusing the sun to a very defined point will not do wonders for your eyeballs. Depending on the intensity of sun, you will get different strokes and thicknesses of line, making every single piece unique, even if it’s the same image. There is a colored safety filter to remove, and you’ll need to hold this at a 90 degree angle to make a mark. This will cost you anywhere from $59-97 depending on what type of wood you’d like.

Pocket-Sized Lantern Connects You to the World Even When There's No Internet Service by Beverley Mitchell




An estimated 4.3 billion people around the world don’t have internet access. In times of natural disasters, internet and phone connections also frequently fail. Lantern is a pocket-sized device designed to bring connectivity to those without internet access, using satellite-broadcast radio waves. The company behind Lantern, Outernet, aims to provide users with an anonymous, portable library that constantly receives free data from space. The device is currently acing its Indiegogo campaign, so read on for details on becoming an early adopter.





So how does Lantern work? The device continuously receives radio waves broadcast from space by Outernet’s satellite transmitters. It turns the signals into digital files, such as readable webpages, ebooks, videos, and music. The device can receive and store any type of digital file, and to view stored files users simply turn on its Wi-Fi hotspot and connect with a Wi-Fi-enabled device. Users just need a browser installed to get going. A homemade satellite receiver could perform the same function, but the Lantern packs down the equipment requirements into a flashlight-sized unit. The device even has its own solar panels to charge itself.
Outernet use the analogy of an FM radio to best describe how the system works: “Outernet is like the radio station and Lantern is the radio.” Users are not accessing the full internet, but rather a curated package of information transmitted by Outernet. Running with the metaphor, they say they are open to receiving requests from users. While this maybe enough to inspire whole forums of conspiracy theories, Outernet are at pains to point out the device’s emergency and remote educational applications.
There is plenty more information about Lantern via their Indiegogo page. A $99 pledge nabs you your own Lantern; a substantial saving off the eventual $149 estimated retail price. Now that they’ve passed their initial funding goal, Outernet are pushing on for the big one: $3 million will allow them to launch their own dedicated Cubesat, $10 million will launch a whole fleet.

History of Solar Energy

1767, First Solar Collector
In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven, reaching temperatures of 230 degrees fahrenheit.
1839, Photovolataic Effect Defined
In 1839 a major milestone in the evolution of solar energy happened with the defining of the photovoltaic effect. A French scientist by the name Edmond Becquerel discovered this using two electrodes placed in an electrolyte. After exposing it to the light, electricity increased.
1873, Photo Conductivity of Selenium
In 1873, Willoughby Smith discovered photoconductivity of a material known as selenium. The discovery was to be further extended in 1876 when the same man discovered that selenium produces solar energy. Attempts were made to construct solar cells using selenium. The cell did not work out well but an important lesson was learned – that solid could convert light into electricity without heat or moving parts. The discovery laid a strong base for future developments in the history of solar power.
1883-1891 Light Discoveries and Solar Cells
During this time several inventions were made that contributed to the evolution of solar energy use. First in 1893 the first solar cell was introduced. The cell was to be wrapped with selenium wafers. Later in 1887 there was the discovery of the ultraviolet ray capacity to cause a spark jump between two electrodes. This was done by Heinrich Hertz. Later, in 1891 the first solar heater was created.
1908, Copper Collector
In 1908 William J. Baileys invented a copper collector which was constructed using copper coils and boxes. The copper collector was an improvement of the earlier done collector but the only difference was the use of copper insulation. The improvements of the invention are being used to manufacture today’s equipments.

1916, Photoelectric Effect
With Albert Einstein publishing a paper on photoelectric effect in 1905 still there was no experimental evidence about it. In 1916 a scientist known as Robert Millikan evidenced the photoelectric effect experimentally.
1947, Solar Popularity in the US
Following the Second World War, solar power equipment started being popular among many people in the USA. There was a huge demand of solar energy equipment.

1958, Solar Energy In Space
Solar power was used to power space exploration equipment such as satellites and space stations. This was the first commercial use of solar energy.
1959-1970, Efficiency of Solar Cells and Cost
During the period between 1959 and 1970 there was major discussion about the efficiency of solar cells and reduction of costs. Up to that time the efficiency of the solar cells was only 14% and was not comparable to the high cost of producing cells. However in the 1970′s, Exxon Corporation designed an efficient solar panel which was less costly to manufacture. This was a major milestone in the history of solar energy.
1977 Governments Embrace Solar Energy
In 1977 the US government embraced the use of solar energy by launching the Solar Energy Research Institute. Other governments across the world soon followed.
1981, Solar Powered Aircraft
In 1981, Paul Macready produced the first solar powered aircraft. The aircraft used more than 1600 cells, placed on its wings. The aircraft flew from France to England.
1982, Solar Powered Cars
In the year 1982 there was the development of the first solar powered cars in Australia.
1986-1999 Solar Power Plants
Evolution of large scale solar energy plants with advancement being made in each phase. By the year 1999 the largest plant was developed producing more than 20 kilowatts.
1999, Breakthroughs in Solar Cell Efficiency
The most efficient solar cell was developed, with a photovoltaic efficiency of 36 percent.
2008, Subsidy Reduction in Spain
Due to the global financial crisis in the year 2008, the Spanish government reduced subsidies on ongoing solar power production in the country. This had a negative effect on the industry across the world.
2010, Evergreen Solar and Solyndra Fail
Two leading solar companies failed. This was due to lack of market for their high technology produced products
2012, Record Breaking Solar Plants
The past few years have seen enormous investment in utility-scale solar plants, with records for the largest frequently being broken. As of 2012, the history’s largest solar energy plant is the Golmud Solar Park in China, with an installed capacity of 200 megawatts. This is arguably surpassed by India’s Gujarat Solar Park, a collection of solar farms scattered around the Gujarat region, boasting a combined installed capacity of 605 megawatts.

White Goat - Your Office will never waste paper


Your office will never waste paper again with Oriental's White Goat machine, which converts normal paper into toilet paper. Simply insert about 40 sheets of paper, and in 30 minutes you’ll receive a freshly made roll of toilet paper. The machine shreds the paper, dissolves it in water, thins it out and then dries it and winds it around a roll. According to Oriental, it costs about 12 cents to churn out one roll.
 
White Goat goes on sale in Japan this summer and will be priced at $100,000. While the machine will definitely make your business more eco-friendly, there is one snag: Where are you going to store this nearly 6-foot-tall machine?

Solar energy - the 'alternative' way forward

Noopur Tiwari, Hindustan Times  Paris, October 05, 2014

The sun could be the world’s largest source of electricity by 2050, ahead of fossil fuels, wind, hydro and nuclear, according to a pair of reports issued by the International Energy Agency (IEA).
Solar photovoltaic systems (PV) could generate up to 16% of the world’s electricity by 2050, while solar thermal electricity (STE) from concentrating solar power plants could provide an additional 11%.
A combination of both these solar technologies could prevent the emission of more than 6 billion tonnes of carbon dioxide per year by 2050 – that is more than all current energy-related CO2 emissions from the United States or almost all of the direct emissions from the transport sector worldwide today.
In most parts of India, the sun is strong and skies are clear with North-western India being one of the most favourable areas for solar power resource.
India will be able to reach the highest reduction in additional CO2 emission in 2050 and along with China could account for half the global additional emission reductions with the help of STE.
While PV is already expanding globally, with China leading the world, followed by the United States, STE is likely to expand further.  This presents a major opportunity for India, which could become the third largest producer in terms of solar power plant capacity, just behind the Middle East and the US.  This is however not a forecast on what will happen but what should happen if the right steps are taken, IEA executive director Maria van der Hoeven clarified.
“Both technologies are very capital intensive: almost all expenditures are made upfront. Lowering the cost of capital is thus of primary importance for achieving the vision in these roadmaps.”
Currently, Spain is the leading country with 2% annual electricity from solar power plants with US at second place. In the rest of the world, UAE and India have the largest plants.

Nation banks on green evolution



China's rapid transition to a green economy will be a boom both to its domestic market and the global economy, especially renewable energy industry, leading experts have said.
Commitment to developing a sustainable economy, emphasizing domestic consumption, and putting a green economy at the heart of the planning process already form the basis of China's ongoing 12th Five-Year Plan (2011-15).
"We definitely need China to succeed if the world is to succeed. Whatever China does will have global repercussions because a lot of the world's manufacturing is going on there," said Nis Hoeyrup Christensen, advisor on Chinese affairs at the Confederation of Danish Industry (CDI), and researcher in China's renewable energy sector at Copenhagen Business School.
He added that a green transition in China's manufacturing model will have especial relevance where it concerns production for the domestic market, "because that amounts to a lot of economic activity."
The UN's Environment Program defines the green economy as one where "growth in income and employment should be driven by public and private investments that reduce carbon emissions and pollution, enhance energy and resource efficiency, and prevent the loss of biodiversity and ecosystem services."
For its part, China is making a green refurbishment of its economy under a number of key headings defined in its 12th Five-Year Plan. These include that value-added output of emerging strategic industries will account for eight percent of gross domestic product (GDP), and that the country's manufacturing base in coastal regions will transit to high-end manufacturing, services and research and development.
Keystones in China's greening process include replacing coal-fired plants with those run on renewable sources like bio-mass, wind energy and solar power. Other areas involve better insulation of homes and offices to cut heating bills, combined urban heating and power networks, more recycling, improving energy-efficiency of production facilities, and developing alternative-fuel cars.
In fact, China is now the world's largest maker of wind turbines and solar panels, and its largest market for wind power. Moreover, the Chinese government says it plans to increase the share of non fossil-fuel based energy in the country's total energy consumption to 11.4 percent in 2015, up from 8.3 percent in 2010.
Green model
Denmark and its Nordic neighbors, who have been first-movers in the global green growth arena, could stand to benefit commercially from China's rapid green transition.
"I believe a more sustainable growth in China can turn out to be an advantage to Danish companies because of the technologies and solutions we have developed in our effort to create a green economy," said CEO of the CDI, Karsten Dybvad.
According to the CDI, the Danish economy has grown 78 percent since 1980, while keeping energy consumption more or less constant and slashing carbon dioxide (CO2) emissions, owing largely to technological developments in renewable energy and energy-saving.
The Danish or Nordic model of green development can be adopted in emerging economies as well, as long as they are scaled-up and adapted to fit local needs, experts say.
In fact, technology adoption and transfer would likely see Nordic technology and energy firms work even more closely with Chinese partners so as to better understand and respond to the needs of China's green market, Christensen said.
New chances
"China is at a crucial stage where the tracks will be laid out for the future direction of welfare policies and economic restructuring," Dybvad said, referring to China's move away from export-led growth and towards greater domestic consumption.
The social impact of re-balancing can perhaps be felt most palpably in the way China expects to care for its rapidly-aging population. According to Chinese official data, the country's elderly population equaled 185 million persons at the end of 2011, and is expected to be 221 million before 2015.
"Danish politicians have talked about exporting our welfare technology for a long time. This means equipment for old people's homes and hospitals, and tools which makes life easier for the elderly and for those who work with them," said Christina Boutrup, author of "China Sweet and Sour", a book on Danish companies' experiences in China.
"While this was just a dream scenario for Danish exporters in the past, China's move towards sustainability means the dream can now be realized," she added, pointing to this burgeoning area of business collaboration.
Although Danish companies can face "fierce competition from local players" when marketing welfare or energy technologies in China, Boutrup believes they hold a competitive edge as they can meet China's increasingly tighter environmental regulations, "even if they are more expensive."
Whatever the specific, future investment areas, companies will need a stable market with clear policy indicators of how best they can deploy their resources over time.
Given the Chinese government's grip on macroeconomic policy, Christensen believes these factors already exist in China and are among the stepping-stones to its green transition.
"If investors are going to put money into establishing a new technology or company, they need to be sure there is a market. In China, there is a market and a clear horizon, which the Chinese government is pretty good at showing, as it puts up both short-and-long term economic goals," he said.
