Solar-Powered Floating Farms That Can Produce 20 Tons of Vegetables Every Day

Posted by in categories: employment, food, solar power, sustainability

Traditional farming has challenges that are now being overcome by innovative and sustainable solutions. One instance is a floating island that is powered by solar energy and has several farms that were created by the Forward Thinking Architecture. The islands are designed to work in an energy efficient manner where rainwater and sunlight are harvested so that the farming is done in a sustainable manner. The floating farms are designed to produce vegetables of the amount twenty tons every day. The advantage of this approach is that it has paved the way for farms such as this to be built and run across the world, even in places that are not accessible or do not have the right resources for farming. Locals can grow the food they need and reduce the need to import food and other goods which can then save money and provide opportunities for local employment. The floating farms and their amazing technology and possibilities are shown below. There are links given as well for those who wish to know more. It surely will revolutionize the problems of food production that has been plaguing many countries.

The world’s largest floating solar power plant is being built in Japan

Posted by in categories: solar power, sustainability

As solar power becomes a bigger and bigger part of the overall energy landscape, engineers around the world are busy working out how to build plants that are large and efficient enough to keep up with demand. Now Japanese electronics giant Kyocera is starting construction on what it says will be the largest floating solar power plant (in terms of overall capacity) in the world.

It’s the fourth such floating plant Kyocera has worked on so far, but this one promises to be the most impressive yet: the facility is going to be built on the Yamakura Dam reservoir to the south-east of Tokyo in Japan, and will pump out 13.7 megawatts (MW) of power once it’s completed in March 2018. Some 51,000 photovoltaic panels will be stitched together to cover around 180,000 square metres (about 44.5 acres) of space.

That’s roughly the same area as 18 soccer pitches, so you get a sense of the sort of scale we’re talking about here. Kyocera says the new plant will provide enough power for 4,970 average households and offset around 7,411 tonnes of CO2 emissions every year that it’s in operation (equivalent to 19,000 barrels of oil).

Google’s Project SkyBender aims to beam 5G internet from solar-powered drones

Posted by in categories: business, drones, habitats, internet, mobile phones, solar power, space, sustainability

Google is working in secret at a spaceport in New Mexico to build and test solar-powered internet drones in a new initiative codenamed Project SkyBender, according to a report from The Guardian today. The company is reportedly renting 15,000 square feet of hangar space from Virgin Galactic — the commercial spaceflight outfit of business mogul Richard Branson — at the privately owned Spaceport America located near a town called Truth or Consequences. The lynchpin of Project SkyBender appears to be cutting-edge millimeter wave technology, which can transmit gigabits of data every second at speeds up to 40 times faster than modern 4G LTE.

Millimeter waves are thought to be the future of high-speed data transmission technology, and may form the backbone of 5G mobile networks. Aereo founder Chet Kanojia’s new startup Starry announced earlier this week it would use millimeter wave tech to bring gigabit internet speeds to people’s homes via Wi-Fi. Millimeter waves have much shorter range than current smartphone signals and are easily disrupted by weather conditions like rain, fog, and snow. Using what’s called a phased array, however, Google and others could potentially focus the transmissions over greater distances.

Google is currently testing the technique with a new solar-powered drone called Centaur and other units made by a division known as Google Titan, which the company formed after it acquired drone maker Titan Aerospace in 2014. The company has a deal with the FCC to continue testing until July, according to The Guardian. It’s also paying Virgin Galactic about $1,000 a day to use its hanger, as well as an additional $300,000 to Spaceport America to construct installations with servers, millimeter wave transceivers, and other tech onsite.

France to pave 1,000km of road with solar panels

Posted by in categories: solar power, sustainability

Not mentioned is that the roads become easier to replace instead of having to repave them.


The minister told a conference of transport authorities last week that the tenders for the “Positive Energy” initiative had already been issued and the tests on the panels would begin in the spring.

According to France’s Agency of Environment and Energy Management, 4m of solarised road is enough to supply one household’s electricity needs, apart from heating, and one kilometre will light a settlement with 5,000 inhabitants.

Tesla’s home battery is finally rolling out. First stop: Australia

Posted by in categories: habitats, solar power, sustainability

According to Nick Pfitzner, the Tesla Powerwall is “a thing of beauty.”

Pfitzner, who lives in Sydney’s Hills District, was one of the first homeowners in Australia to have the highly anticipated energy storage battery installed at his home on Thursday.

Tesla announced in September it would be bringing the Powerwall to Australia, with a spokesperson telling Mashable Australia the country had been “prioritised as a market” due to its high number of solar energy users.

Can we Afford to go Into Space?

Posted by in categories: business, economics, materials, military, solar power, space, sustainability

Space is not a government program; it’s the rest of the Universe. Private space business is now a major factor, bent on finding investors interested in generating profits by making space more accessible to more people. Space business pays taxes to governments; it does not consume tax revenues. Further, space business can offer launch services to government agencies at highly competitive rates, thus saving taxpayer dollars. How can they do this, competing with government-funded boosters with a 50-year track record? Simple: governments have no incentive to cut costs. Traditional aerospace industry giants have a huge vested interest in boosters that were developed to military and NASA standards, among which economy was not even an issue. But innovative, competitive companies such as XCOR Aerospace and Mojave Aerospace, without such baggage (and overhead) can drive costs down dramatically. This is a proven principle: notice that we are no longer buying IBM PCs with 64 k of RAM for $5000 a unit.

Even more important in the long view, space is a literally astronomical reservoir of material and energy resources. The profit potential of even a single such resource, such as solar power collectors in space beaming microwave power to Earth, is in the trillions of dollars. What would it be worth to the world to reduce fossil fuel consumption by a factor of 20 or 100 while lowering energy costs? Can we afford to continue pretending that Earth is a closed system, doomed to eke out finite resources into a cold, dark future?

Can we afford space? Wrong question. Can businesses afford space? Yes. We get to reap the benefits of their innovative ideas and free competition without footing the bill.

Material could harvest sunlight

Posted by in categories: materials, solar power, sustainability, transportation

Imagine if your clothing could, on demand, release just enough heat to keep you warm and cozy, allowing you to dial back on your thermostat settings and stay comfortable in a cooler room. Or, picture a car windshield that stores the sun’s energy and then releases it as a burst of heat to melt away a layer of ice.

According to a team of researchers at MIT, both scenarios may be possible before long, thanks to a new material that can store solar during the day and release it later as , whenever it’s needed. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.

Although the sun is a virtually inexhaustible source of energy, it’s only available about half the time we need it—during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering in the form of electricity, but the new finding could provide a highly efficient method for storing the sun’s energy through a chemical reaction and releasing it later as heat.

These Technologies Will Shift the Global Balance of Power in the Next 20 Years

Posted by in categories: business, economics, habitats, solar power, sustainability, transportation

Governments, businesses, and economists have all been caught off guard by the geopolitical shifts that happened with the crash of oil prices and the slowdown of China’s economy. Most believe that the price of oil will recover and that China will continue its rise. They are mistaken. Instead of worrying about the rise of China, we need to fear its fall; and while oil prices may oscillate over the next four or five years, the fossil-fuel industry is headed the way of the dinosaur. The global balance of power will shift as a result.

LED light bulbs, improved heating and cooling systems, and software systems in automobiles have gradually been increasing fuel efficiency over the past decades. But the big shock to the energy industry came with fracking, a new set of techniques and technologies for extracting more hydrocarbons from the ground. Though there are concerns about environmental damage, these increased the outputs of oil and gas, caused the usurpation of old-line coal-fired power plants, and dramatically reduced America’s dependence on foreign oil.
