Chennai is readying to give India its solar atlas, which will have details on radiation of solar energy in various cities in the country.
A team of experts set up by the ministry of new and renewable energy are sitting in Chennai and updating the data of radiation of solar energy in 50 existing automatic solar radiation monitoring centers, including seven in Tamil Nadu, starting from Ladhak in Kashmir to Chitradurga in Karnataka. Sixty more data centres would be set up shortly.
Those of us who worry about mobile phones draining out of charge while travelling may have a solution – solar mobile rechargers that use sunlight instead of electricity. Among the innovations on display at ‘Renergy’, a two day international conference and expo on renewable energy inaugurated on Monday, the most attractive was the solar mobile charger.
In the land of abundant sun, Indians suffer from vitamin D deficiency. There’s been a set of studies to prove this, but new research suggests this deficiency, which can lead to life threatening emergencies in young population, has not led to protective bio-adaptation over time.
After their first systematic study of blood serum in 2000, which showed more than 75% of healthy people studied in northern India had vitamin D deficiency, researchers have now shown that though our skin has darkened while adapting to tropical climate, there is no bio-adaptation to this deficiency. In other words, the dark skin, which prevents ultraviolet rays mediated vitamin D to be formed in the body, does not lead to over-expression of vitamin D receptor, a hormone that regulates calcium levels in the body.
