French developer EDF Energies Nouvelles is commissioning the 30MW Khilchipur solar project in India.
The facility in Madhya Pradesh is the developer’s first PV installation in the country and five further PV projects totalling 120MW are under development in Rajasthan.
EDF won the quintet in a call for tenders by the Indian government and the schemes are all due to be commissioned during 2015.
Work is being led by ACME Solar Energy Private Limited, in which EDF Energies Nouvelles has a 25% interest.
Pranav Agarwal has developed a solar-powered device that aerates the surface of stagnant water in order to prevent mosquitos from laying their eggs and therefore from proliferating.
Mosquitos like to lay their eggs in stagnant or still water -- the females need the surface of the water to be still in order to deposit up to 400 eggs at a time and the larvae need to stay in contact with the surface of the water in order to breathe. The Solar Scare Mosquito aims to curb the spread of mosquito-carried diseases such as malaria and dengue by disrupting the insects' breeding grounds. It works by sitting on the surface of the water and generating air bubbles at regular intervals to produce ripples in a radius of up to two metres.
The device -- which Agarwal built for less than $10 (£6) -- features a bubble aerator, an air pump and a solar charger. It floats on the water and runs at regular intervals in order to disrupt the surface of the water and kill off mosquito larvae. In tests, the tool managed to reduce mosquito populations in a small pool to almost nothing within a week. Agarwal has outlined how to build the device in a blog post.
More and more, many of us exchange drinking regular water with soft drinks. But soft drinks are not a healthy alternative, as we well know. But how unhealthy is it really? What potential adverse effects can drinking a certain amount of soft drinks lead to? This info graphic was prepared and summarized to get these important points across.
Archerfish are remarkably accurate in their shooting; adult fish almost always hit the target on the first shot. They can bring down insects and other prey such as grasshoppers, spiders and butterflies, on perches, up to 3 m above the water's surface. This is partially due to their good eyesight,but also their ability to compensate for the refraction of light as it passes through the air water interface when aiming for their prey. They typically spit at prey at a mean angle of about 74 degrees from the horizontal, but can still aim accurately when spitting at angles between 45 and 110 degrees.
Awesome Invention!
When Cynthia Koenig, a young social entrepreneur from New York, learned that millions of girls and women around the world spend hours each day collecting water from distant sources, she decided to create a new way to help people in poor communities transport water and it's called the WaterWheel. Koenig's WaterWheel allows people to roll water in a 50-liter container versus carrying it in 5 gallon (19 liter) jugs. Koenig estimates that the WaterWheel can save women 35 hours per week in water transport time, as well as prevent the physical strain that comes from balancing 40 pounds of water on top of their heads for hours each day.
Every day around the world, over 200 million hours are spent each day fetching water, often from water sources miles from home, and this task usually falls to women and girls. By freeing up valuable time, the WaterWheel allows women to spend time on income-generating activities that can help pull her family out of poverty. The time savings also means that there is a greater likelihood that girls will be allowed to stay in school, further reducing the rate of intergenerational poverty.
As cubs a lion, a tiger, and a bear had been owned by a drug dealer who did not properly care for them. The bear’s harness grew into his skin because the owner did not alter it as the animal grew. They had been abused and neglected early in life, but were finally rescued. The bear's harness was surgically removed.
After they had been taken in by an animal sanctuary in Georgia, the staff tried to separate them due to obvious concerns that the three large predators would fight. During the trial of separation, the animals were uncooperative and behaved poorly. Once reunited, the three calmed down and were well behaved.
Twelve years later, the three friends spend their days playing, cuddling, and eating together. There are no plans to separate these lifelong friends.
