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?
Wattway, part of the France Colas constructions company, announced that four SolarRoad pilots will be built around the world in 2017.
Bloomberg December 4th:
(…) Colas SA, a French engineering firm, has designed rugged solar panels, capable of withstanding the weight of an 18-wheeler truck, that they’re now building into road surfaces. After nearly five years of research and laboratory tests, they’re constructing 100 outdoor test sites and plan to commercialize the technology in early 2018. (…/) Read More
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
Fuel cells (and perhaps other technologies which use hydrogen) fill certain niches in which batteries cannot compete favorably and the opposite is also true.
When I first realized that the world is transitioning from fossil fuels to renewable energy, I fell in love with hydrogen technologies.
Splitting the most naturally abundant compound in the world, H2O, would be the ideal thing to fuel the future. However, there are really dangerous details to how this water must be split and the energy requirement is quite ridiculous.
In addition, changes in weather patterns in the Caribbean due to climate change are exacerbating existing water challenges.
Desalination is not new to the Caribbean, but extracting clean water from seawater is becoming an increasingly integral part of the region’s search for water security.
Since 2007, 68 new desalination plants have been built across the Caribbean, which now boasts an installed capacity of 782,000 cubic metres of purified water per day, according to the Caribbean Desalination Association.
The 250-MW Bujagali hydropower plant in Uganda demonstrates that large-scale private power infrastructure projects can be built successfully in Africa. This is the first power project built in Uganda to secure private financing.
Since September 13, 2012, an enormous underwater turbine in Maine’s Cobscook Bay began sending power inland to the Bangor Hydro electrical utility grid. It was a historic moment for clean power: the first commercial-scale, grid-connected tidal energy generator anywhere in the USA. Read More
