Baldness gives unhappiness to a person. People feel it as a sign of getting old and the person feels that because of his baldness his looks suffer. People will do anything and go to any length to get a good crop of hair on their head. Worldwide hair loss treatment industry is worth $ 3.5 billion/year.

However, new scientific evidence suggests that infrared (IR) radiation in solar energy is transmitted through bald head and may help in repair of neurons, their generation, and stop or reduce the ravaging affects of Parkinson’s disease.

In all ancient civilizations whether Greek, Egyptian, Indian etc. and in various religions, baldness or shaven head was identified with philosophers, monks and priests. Some say that it was done to differentiate such people from common folks. Thus a person with shaven head wearing an ochre robe is normally identified as a Buddhist monk or a Sanyasi.

The  ancients understood the power of solar energy on the bald head and hence the practice developed. Thus it is possible that our ancient tradition of invoking Gayatri Mantra and practicing Surya Namaskar could be traced to the understanding of beneficial effects of solar energy radiation on human body.

Bald human skull allows 10% of incident IR radiation to pass through it. IR radiation which has wavelength of 750-1500 nanometers is not visible to the naked eye and is the source of heat. On the other hand visible radiation has wavelengths in the range of 450- 750 nanometers.

Around 50% of solar radiation falling on earth is in the IR range. Nature uses this radiation very effectively since it helps in producing wind, evaporating sea water to form clouds and produce rain and to help the neurons function effectively in brain.

How the IR radiation helps in neuron repair and regeneration is still not fully understood. Some scientists say that IR, since it is mostly heat, helps in increasing the brains temperature and hence the activity of neurons while others say that the mitochondria, the engine which provides energy to cells gets repaired and energized by it leading to neuron repair and generation. Nevertheless the beneficial effect of IR on brain is evident and has been shown in human and animal trials.

Infrared light therapy nowadays is also being used and promoted as a powerful and noninvasive treatment for patients suffering strokes, head injuries and as an eye treatment.

The penetration of IR radiation into human brains is quite shallow and attenuates within 2-3 cms of entering the brain tissue but the blood flow in the brain allows the regenerated and repaired brain cells to be transported to different parts of brains.

Why are neurons affected by IR radiation? A possible explanation could be that during their firing they produce a feeble radiation in the IR range and by principle of equivalence they react positively to it.

So bald people, rejoice that nature and especially solar energy will help you in improving your brain and provide happiness since a supple and powerful brain is necessary for creating happiness. The main thing is to sit in the sun for 10-15 minutes everyday. Not only will your brain become better but you will also get much needed vitamin D.

India’s Floating Solar Panel a Gateway To Clean Energy For Asia

India already makes the solar panels it needs, and is now setting up manufacturing for the floats and anchors needed for floating solar systems.

When the worst floods in a century swept through India’s southern Kerala state in August, they killed more than 480 people and left behind more than $5 billion in damage.But one thing survived unscathed: India’s first floating solar panels, on one of the country’s largest water reservoirs.

As India grapples with wilder weather, surging demand for power and a goal to nearly quintuple the use of solar energy in just four years, “we are very much excited about floating solar,” said Shailesh K. Mishra, director of power systems at the government Solar Energy Corporation of India.

India is planning new large-scale installations of the technology on hydropower reservoirs and other water bodies in Tamil Nadu, Jharkhand and Uttarakhand states, and in the Lakshadweep islands, he told the Thomson Reuters Foundation.

 

Solar panels
Currently floating solar arrays cost about 18 percent more than traditional solar photovoltaic arrays.

“The cost is coming almost to the same level as ground solar, and then it will go (forward) very fast,” he predicted.

 

As countries move to swiftly scale up solar power, to meet growing demand for energy and to try to curb climate change, floating solar panels – installed on reservoirs or along coastal areas – are fast gaining popularity, particularly in Asia, experts say.

The panels – now in place from China to the Maldives to Britain – get around some of the biggest problems facing traditional solar farms, particularly a lack of available land, said Oliver Knight, a senior energy specialist with the World Bank.

“The water body is already there – you don’t need to go out and find it,” he said in a telephone interview.

And siting solar arrays on water – most cover up to 10 percent of a reservoir – can cut evaporation as well, a significant benefit in water-short places, Knight said.

Pakistan’s new government, for instance, is talking about using floating solar panels on water reservoirs near Karachi and Hyderabad, both to provide much-needed power and to curb water losses as climate change brings hotter temperatures and more evaporation, he said.

Solar arrays on hydropower dams also can take advantage of existing power transmission lines, and excess solar can be used to pump water, effectively storing it as hydropower potential.

Big Potential

China currently has the most of the 1.1 gigawatts of floating solar generating capacity now installed, according to the World Bank.

But the technology’s potential is much bigger – about 400 gigawatts, or about as much generating capacity as all the solar photovoltaic panels installed in the world through 2017, the bank said.

“If you covered 1 percent of manmade water bodies, you’re already looking at 400 gigawatts,” Knight said. “That’s very significant.”

Growing use of the technology has raised fears that it could block sun into reservoirs, affecting wildlife and ecosystems, or that electrical systems might not stand up to a watery environment – particularly in salty coastal waters.

But backers say that while environmental concerns need to be better studied, the relatively small amount of surface area covered by the panels – at least at the moment – doesn’t appear to create significant problems.

“People worried what will happen to fish, to water quality,” said India’s Mishra. “Now all that attention has gone.”

What may be more challenging is keeping panels working – and free of colonizing sea creatures – in corrosively salty coastal installations, which account for a relatively small percentage of total projects so far, noted Thomas Reindl of the Solar Energy Research Institute of Singapore.

He said he expects the technology will draw more investment “when durability and reliability has been proven in real world installations.”

Currently floating solar arrays cost about 18 percent more than traditional solar photovoltaic arrays, Knight said – but that cost is often offset by other lower costs.

“In many places one has to pay for land, for resettlement of people or preparing and leveling land and building roads,” he said. With floating solar, “you avoid quite a bit of that.”

Solar panels used on water, which cools them, also can produce about 5 percent more electricity, he said.

Mishra said that while, in his view, India has sufficient land for traditional solar installations, much of it is in remote areas inhospitable to agriculture, including deserts.

Putting solar panels on water, by comparison, cuts transmission costs by moving power generation closer to the people who need the energy, he said.

He said India already makes the solar panels it needs, and is now setting up manufacturing for the floats and anchors needed for floating solar systems.

When that capacity is in place, “then the cost will automatically come down,” he predicted. (VOA)
