Once we get in there, put it in place and anchor it down, that’s it. When the water starts flowing in and turns the generator, we make electricity, and we’re able to put it in the distribution grid.
The potential for generating hydroelectric river power has been overlooked. At least until now. This cross-flow turbine from KWRiver can capture the power of the flow of water over the weir of a low-head dam. A low-head dam is defined as one having an elevation difference of less than 15 feet.
The turbine can fit into dams with little or no structural modification needed. The system is even compatible in a river with a smooth flow of water with a current of 10 m³/s and a small inclination. Read More
The Oregon Solar Highway Program seeks to further the use of solar energy in greening the nation’s grid, adding value to the existing public right of way, and supplying clean, renewable, home-grown energy to Oregonians.
In 2008, the Solar Highway Project in Oregon (USA) was one of the first eye catcher world wide. Right now, there are a lot of examples of PV along the highways that power grids.
Because of the project’s high visibility, the team also took more extreme security measures than most projects need. A fence with razor wire and a motion detector surround the panels, protecting them from theft and graffiti. The 594-module, 104 kW project costed about $12.50 per W – about 50 percent higher than the average price for commercial projects installed that year in the state.
In the future, private households will be capable of contributing to the stabilization of the power grid by enabling better integration of renewable energies.
TenneT and Sonnen are pioneering the networking of storage batteries with blockchain technology in order to stabilize the power grid.
Private households and owners of electric cars charged at these households, will be capable of contributing to the stabilization of the power grid by enabling better integration of renewable energies. Read More
pressure-compensating drippers to operate at 0.1 bar — one-tenth of the pressure of commercial systems
Engineers at MIT have found a way to cut the cost of solar-powered drip systems by half, by optimizing the drippers.
These new drippers can halve the pumping power required to irrigate, lowering energy bills for farmers.
The team modified the drippers’ dimensions in a way that significantly reduces the pressure required to pump water through the entire system, while still delivering the same amount of water.
The V-shaped turbine is modeled on the lines of conventional turbines, however, with a sting of advancing technology. The difference between the conventional windmills and aero-generator is that the later generates power through a rotating vertical shaft, while the horizontal shafts form an important part of the former.
Look at this beautiful wind turbine designs.
The increasing demand for green electricity is like food for designers. Conventional horizontal axis wind turbines come with their own set of issues ranging from spoiling the view of the landscape to causing birth deaths and health related problems for people living nearby.
Research is on to find alternative designs, which can answer all the issues, while still providing enough energy to power homes and industries. Here is a list of some of the most innovative designed wind turbines for the future. Read More
There is about a 300 000 volt (V) potential difference between the Earth’s surface and the electrosphere, which gives an average electric field strength of about 6 V/metre (m) throughout the atmosphere. Near the surface, the fine-weather electric field strength is about 100 V/m..” Average height of a man is 6 feet or 2 meters so 100 V/m x 2 meters = 200 Volts 6 feet off the ground.
A black electromagnetic energy receiving antenna absorbs all electromagnetic radiation and doesn’t reflect at all.
Pure clean energy with a simple antenna. Is that possible? It seems to be.
The Egyptians used it 2000 years ago. We did it when our TV was still for free. But we seem to have forgotten it. Read More
Leading in alternative energies supports the kind of sustainable economic development and cost savings for our homeowners and businesses that we need.” – Mayor Emanuel
More than 900 government buildings in Chicago will shift their electricity use to “100% renewable energy” by 2025 under an ambitious mayoral plan that contrasts sharply with President Donald Trump’s retreat on environmental issues.
Three scientific breakthroughs will enable us to quickly reduce these emissions according to venture investor Bill Joy.
It can not be missed: we have to combat our CO2 emissions to stop climate change.
We have some news: Three scientific breakthroughs will enable us to quickly reduce these emissions according to venture investor Bill Joy. A pre-publication – including an update of the companies he mentions. Read More
In the transition period, storage and transportation of fossil fuels such as gasoline, diesel and kerosene will grow. International cargo flows remain important als long as societies still can not fully rely on green alternatives.
At its core, blockchain technology is a way to transfer any kind of data or information in a fast, tracked, and secure way without the need for an intermediary institution. Initially developed to allow peers to directly exchange digital currency faster and at lower cost, blockchain is now yielding a variety of promising new solutions beyond financial services.
The blockchain technology has attracted public interest as it provides an effective instrument to satisfy the needs of people to cooperate horizontally with each other in economic and social spheres like energy microgrids.
Blockchain technology is an innovative method of storing and validating data that permits direct transactions between energy producers and consumers.
In 1989, the organization changed the design of a drilling platform in order to take account of extreme weather and rising sea levels.
Shell produced a report on global warming called ‘Climate of Concern’ in 1986. In 1991 they made the video documentary for the public. It warned that trends in global temperatures raised serious risks of famines, floods and climate refugees.
But in the quarter century since, Shell has continued to invest heavily in fossil fuels.
Already in the eighties, Shell understood that climate change would affect its own operations. In 1989, the organization changed the design of a drilling platform in order to take account of extreme weather and rising sea levels.
Festivals encourage the donation of urine. It could be also used for batteries according to Standford University
Researchers at Stanford University have developed an inexpensive battery for renewable energy. This is done by making use of urea, a substance which is to be found in fertilizers and urine. Isn’t this great news?
If you can prove something like a hydrogen society can work in a city like Tokyo, then it’s a matter of how do they scale it, how do the Japanese ensure that all the ancillary consequences have been addressed, and you only really do this by testing it out.
Japan is moving faster than expected toward an hydrogen energy future. Prime Minister Abe has become a vocal advocate for hydrogen – both to stimulate developments in technology and to help the resource-poor nation lower greenhouse gases. With Japan relying more on fossil fuels since the shuttering of most of its nuclear reactors after the Fukushima disaster almost six years ago, it’s a push that’s gained more urgency.
Toyota is at the forefront of Japan’s efforts to use hydrogen and fuel cells to power cars, heat homes and keep factories running. Other companies pursuing the technology include Panasonic Corp, Toshiba Corp and JX Nippon Oil & Energy Corp. Read More
