Severe drought threatens to run taps dry in Cape Town
How did Cape Town deal with its “Day Zero” water crisis and what can we learn? Intense drought in South Africa’s Western Cape Province has led the world-renowned city of Cape Town to the brink of “Day Zero”. Day Zero was the date at which residents would be forced to collect strictly rationed water supplies from shared distribution taps. Read More
MVRDV wins competition for landmark public installation in Den Helder with ‘infinite loop’ design
This stunning Seasaw concrete sea defensewill rock back and forth with the tide along the Dutch seashore. MVRDV recently won a competition to design a unique permanent art installation for the scenic coastal Dutch city of Den Helder.
The design, which will rise on a historic dyke north of Amsterdam, is a curvilinear observation platform that twists into an infinite loop perched several feet over the sea. Read More
Recent experiences in the United States demonstrate that new technologies and systems, including mini-grids and the communication and automation technologies that sync them with traditional power sources, can help prevent energy crises like the one being experienced in Puerto Rico
When we talk about renewable energy sources like solar and wind we need appropriate forecasting as it can affect the grid integrated to the solar or wind system as it can lead to frequency fluctuations, along with appropriate forecasting we need to have data for demand and supply in which area and at what time as demand and supply prediction along with appropriate forecasting will be helpful in making a grid resilient.
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.
With the federal government casting off the task of emissions reduction, initiatives are now on cities and states to make up the shortfall. This is what the cities are doing to stave off the threat of climate change. Read More
Tiny holes called nanopores, is specially designed to let high volumes of water through but keep salt and other contaminates out
MoS2 Nanopores, developed by the University of Illinois, seems to be an energy-efficient technique for removing salt from seawater. The material, a nanometer-thick sheet of molybdenum disulfide (MoS2) riddled with tiny holes called nanopores, is specially designed to let high volumes of water through but keep salt and other contaminates out, a process called desalination.

According to climate researchers, more rain than snow will fall in the Arctic. Moreover, oceans are getting hotter, and they’re also losing oxygen
According to climate researchers in the Netherlands, at the end of this century more rain than snow will fall in the Arctic. It was already known that, due to global warming, up to 60% more precipitation would fall in the Arctic.
The researchers now argue that it mainly involves rain, while scientists always presuppose the precipitation would be snow. Read More
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.
Between the years 1986 and 2006, Toronto experienced not one but eight storms of the magnitude that had been predicted to occur no more than once in a quarter-century. The Finch Avenue Washout was the capper, a one-in-100-years storm for which the city’s infrastructure was woefully under-designed.
The Netherlands is to host a new Global Centre of Excellence on Climate Adaption (GCEA), set up by the Dutch and Japanese governments in collaboration with the UN environment programme (UNEP).
The centre will advise countries, businesses and organizations on how to adapt their practices to comply with the Paris climate change agreement, which comprises measures designed to keep the global temperature increase below 2 degrees.
Working of the capacity down pipe (1, empty; 2, filling-up; 3, over-flowing; 4; full; 5, drained)
A case study in Manchester with different solutions for water infiltration and retention systems, showed that soak-aways and infiltration trenches are generally less preferred than capacity down pipes, ponds and filter strips.
And this wateringpipe – the capacity downpipe (CDP) – works even better.
Flared gas is a bigger problem than thought. Contrary to what has been agreed with the oil industry, worldwide the industry flared not less, but more gas.
In 2015, about 147 billion cubic meters which is a CO2 footprint of around 350 million tonnes!
The world bank published the figures in a report. Globally, over 16,000 oil wells are flaring gas.
The amount of wasted gas corresponds to the gas consumption of the UK, Germany and Switzerland together. If the gas was burned in a power plant, it could supply the whole of Africa with electricity. Read More
The next few decades will be the most rapid period of urban growth in human history, with 2.6 billion additional urban dwellers expected by 2050 (UNPD, 2011). All pleople will need water, but surprisingly little is known globally about where large cities obtain their water or the implication of this infrastructure for the global hydrologic cycle.
More than 2.5 billion people don’t have access to basic levels of fresh water for at least one month each year – a situation growing ever more critical as urban populations expand rapidly
Traditionally, cities, facing increased demand for water, along with variable supply, have relied on large-scale, supply-side infrastructural projects such as dams and reservoirs.
This is termed ‘supply-side’ management. According to Robert Brears in his blog, this supply-side management is out dated.
Its costly in economic, environmental and political terms. Read More
