This revolutionary wind/solar energy tower is 2,235 ft high and 1,200 ft width.
Mexico is making history with this hybrid solar & wind energy tower. Have you ever seen this?
The simplicity of solar/wind energy’s revolutionary solution lies in its ability to harness the natural power of a downdraft created when water is introduced to hot dry air within the confines of the Company’s patented tower structure.
In response to worsening air pollution problems in many of Europe’s largest cities, Barcelona (Spain) and Munich (Germany) have been moved to action. In Barcelona’s case, voluntarily, and in Munich’s case, as the result of a court order.
From 2018 there will be bans on diesel cars in Munich.
The court order in Munich follows legal action taken by Transport and Environment’s German member DUH to force action on Bavaria’s breaching of EU air pollution limits in some locations.
During reel-out, the kite is flying figure-eight maneuvers at high speed (70 to 90 km/h). This creates a high traction force (3.1 kN at 7 m/s wind speed) which is converted into electricity by the drum and the connected 20 kW generator.
Kite Power by harnessing high altitude wind next step in Dutch Icon project ‘Afsluitdijk’.
Even NASA has started to work on airborne wind energy. This field is very new and has much room for innovation.
Flight testing with actual consistent measured power production is the next step.
Last week the German government reported that the Portugal produced so much renewable energy on a particularly sunny, windy Sunday that there was a power surplus.
In may 2016, Portugal ran for more than half a week without having to resort to fossil fuels. Thanks to a big push toward solar, wind, and hydro power and a little nudge from the EU, for four days, Portugal produced enough clean, sustainable electricity to meet the needs of its people. Read More
Aquion did come up with a breakthrough saltwater battery. It is environmentally friendly, cost effective and has a life cycle way beyond any other battery: up to 5,000 cycles.
The development of sustainable saltwater batteries enters the next level.
The American company Aquion Energy has received $ 33 million extra finance.
Previously, Bill Gates invested in Aquion Energy.
Aquion developed batteries that can store solar and wind energy to serve as backup for times when there is no wind nor sun. Saltwater batteries are not new, but the batteries from Aquion are special because they are using salt water as a conductor, instead of acids or bases.
Aquion has come up with a clever twist on a 200 year old salt water battery technology using:
Activated carbon (anode)
Manganese oxide (cathode)
And basically a salt water electrolyte
They have come up with a breakthrough solution. It is environmentally friendly, cost effective and has a life cycle way beyond any other battery: up to 5,000 cycles
So what’s Aquion’s energy storage innovation?
The startup — which was backed by Bill Gates and VCs like Kleiner Perkins and Foundation Capital — is making a low cost, modular grid battery made from basic materials like sodium and water.
The battery pairs a carbon anode with a sodium-based cathode, and a water-based electrolyte shuttles ions between the two electrodes during charging and discharging.
The technology was developed out of Carnegie Mellon University by founder and chief technology officer Jay Whitacre.
By using basic materials, Aquion is hoping its product is inexpensive enough to disrupt the current grid battery market.
Aquion’s CEO Scott Pearson:
“When the battery has been manufactured at a commercial scale for awhile, the price point of the battery could be $300 per kilowatt hour. That’s about a third of the cost of some of the more expensive lithium ion battery grid products.”
Saltwater batteries are tolerant to wide temperature ranges, partial state of charge cycling, and daily deep cycling with minimal degradation.
In addition to the safety and sustainability advantages of using water as electrolyte, another advantage is the thermal mass of the embodied water means that Aquion products neither heat nor cool rapidly. As such, the products can operate in a very wide operating temperature window because they simply take so long to heat and to cool.
The saltwater battery chemistry relies on charge/discharge mechanisms which are unaffected by partial state of charge – these batteries can sit indefinitely at partial, or even no state of charge, without irreversible capacity loss like lead acid batteries.
In June 2016, Aquion Energy has introduced the Aspen 24S, a 24-volt version of its award-winning Aqueous Hybrid Ion (AHI) battery.
The new product is designed for energy-intensive applications that use solar panels, such as off-grid solar-powered LED lighting, as well as small pumps and motors. It is also an ideal drop-in replacement for existing systems using 24-volt lead-acid batteries.
This glider, called the ‘PowerPlane’ is a green energy turbine that extracts energy from the wind much more economically than conventional wind turbines.
PowerPlane systems convert wind power into mechanical power by having an autopilot-controlled glider plane creating pull on a tether by flying repetitive cross-wind patterns at an altitude of 300 to 600 meters. Read More
Sam Molenaar believes that, with further optimization, the bacteria-based battery could rival the performance of lithium-ion batteries at a lower cost and with greater safety.
A rechargeable battery driven by bacteria? Lithium-ion batteries are limited by safety issues, high costs and other factors. Sam Molenaar and his colleagues from Wageningen University wanted to come up with a less expensive, more sustainable solution.
The research team combined two separate microbial energy systems. One system used bacteria to form acetate from electricity, while the other one converted the produced acetate back into electricity. Read More
in 2014, companies in the electric transportation sector accounted for 820 million euro.
In 2014, the number of employments in electric vehicles increased by 25% to 3,200 jobs in the Netherlands.
Dutch companies in circular electric transport are doing a great job. National and international. Important, because they do not only contribute to our economy but they also are part of the solution to the global energy and climate issues. Read More
