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
Of the 315 million people who are expected to gain access to electricity in Africa’s rural areas by 2040, it is predicted that only 30% will gain access to national grid-connected electricity
A new report from former UN Secretary-General Kofi Annan’s Africa Progress Panel has called for a “significant boost” in investment to help African governments and their partners to “bridge the continent’s huge energy gap.”
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
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
If this large-scale storage of renewable energy in liquid ammonia succeeds, communities can cover long low wind and solar energy periods
The Battolyser, which will be used as a super battery in a gas power plant, is becoming a reality.
For the first time, TU Delft researchers led by Prof. Fokko Mulder have produced an integrated battery electrolysis system – known as a ‘battolyser’ – that can not only store or supply electricity efficiently as a battery but can also split water into hydrogen and oxygen using electrolysis.

The magnetic motor works on the simple principle that we all already know, ‘Like poles repel each other while opposite poles attract each other’. By arranging the magnets in a fashion where only like poles face each other, one can simply set the motor into motion like in the video below.
The solar cells at the second side are are almost as efficient as the cells in the front end. As a result, the panels can also utilize the light that is reflected by the surface of the water or the ground, which normally is lost.
By applying double-sided panels – working on water – the yield of solar power can be increased by 20% on average and expand the potential to generate solar energy even more.
So why not use both sides?
Double-sided solar panel
This week, Energy Research Centre (ECN) is demonstrating ‘floating double-sided solar panels on the ‘River IJ’ in Amsterdam. By also using the back of the solar panels, the reflected light from the surface of the water, can be catched to generate electric power. Read More
The challenge we face is big, perhaps bigger than many people imagine. But so is the opportunity. If the world can find a source of cheap, clean energy, it will do more than halt climate change. It will transform the lives of millions of the poorest families.
Every year, Bill Gates writes a letter to students.
This year’s letter is about our climate and energy transition towards a renewable energy world.
In his letter, he notices that that all plans and existing techniques will not be sufficient enough to stop the global warming.
This year, Gates appeals to the students of today. Read More
“We have got a very good year,” according to IKEA Group President and CEO Peter Agnefjäll at the presentation of the Annual Review and Sustainability Report of the past year. “As a result we have been able to continue significant investments in sustainability, improving our product portfolio and more increasing the number of our stores.”
Yesterday, US Secretary of State John Kerry announced a doubling of the US payments on climate aid from 430 to $ 860 million in 2020. With this gesture of goodwill the White House hopes for a possible signal from the developing countries.
Yesterday, the new concept agreement was finished. Just two hours later than promised.
