The nearby residents and slum dwellers are continuously entering the biological park illegally and it has been a serious menace to the authorities of the Patna Zoo, sources reported from Patna.

“Recently we caught hold of many young boys for entering the zoo campus by jumping the boundary wall and creating nuisance. They were either involved in plucking flowers, disturbing animals or passing comments on visitors,” said an official.

Due to low outer fence, many locals from nearby localities also cut tree branches that come outside the zoo campus. “All trees are zoo’s property and damaging them is a crime. Locals residing in slums area near the zoo often cut the branches for bonfire,” the official said.

For years, the Patna zoo has been facing such incidents but not a single case has been filed with police. “We can lodge complaint with the police for cutting branches of the tree. But we usually avoid it because it happens only in winter season. And the persons, who are involved in it, are very poor,” the official said.

However, zoo director S Chandrashekhar said, “We are planning to raise the outer boundary wall of the zoo. We will soon construct solar electricity fencing to keep those persons away from the bou

The solar thermal plants are becoming far-realized dreams in India, even in the opinion of firms like Green World Investor. The main reason for such belief is the most atrocious bids by the companies like Reliance and Lanco, who had participated in the reverse auction of phase 1 of the Jawaharlal Nehru Mission. The solar PV developers were however revived from the blow of reduced solar panel prices, but same cannot be said in case of solar thermal developers. The CSP technology has suffered a lot of bankruptcies due to the solar PV prices touching rock bottom. The CSP technology has major disadvantages when compared with Solar PV.

Solar thermal developers have already got an extension of 10 months and still they are nowhere near completing their solar thermal plants. Only one developer has completed the 50 MW plant, while others are still sitting on their asses waiting for divine intervention to bail them out.

Now these utilities Lanco and Reliance are starting to put the blame on the ministry for the lack of their own performance and stupidity. They are citing wrong DNI data for not completing their plants. Their excuse is that they got the wrong date from the ministry on solar radiation for their plants, which will affect their return projections. This argument simply does no

In 2013, India saw a sun powered PV limit expansion of 905 MW. At the close of 2013, India’s aggregate introduced limit remained at 2,123 MW. The principal quarter of 2013 saw the biggest limit expansion for the year at 408 MW. This was generally determined by the due date for charging of the National Solar Mission (NSM) ventures. The establishment limits for the last 75% of 2013 were curbed and all in all determined by a few undertakings that surfaced under the Madhya Pradesh and Karnataka arrangements plus various little Renewable Energy Certificate (REC) driven activities. Limit augmentations in each of the last seventy five per cent additionally remained reach bound under 200 MW.

Within this range bound capacity addition, there has been a general uptrend in ground mounted projects driven by parity and being set up for multi-party captive consumption or third-party sale of power. These projects are generally being set up as ‘solar parks’ that are driven by engineering, procurement and construction (EPC) companies and/or project developers who bring investors and power consumers on board. In most cases, to be able to avail taxation benefits, the power consumers are also the investors.

The recent study has made a path breaking discovery of storing solar energy even in the absence of Sun during night. The discovery has devised a system by which the Suns energy is stored not as power but as hydrogen fuel for future use of powering other devices in the absence of Sun.

“So called ‘solar fuels’ like hydrogen offer a solution to how to store energy for night-time use by taking a cue from natural photosynthesis,” said Tom Meyer, Arey distinguished professor of chemistry at the energy frontier research centre at University of North Carolina (UNC) at Chapel Hill.

“Our findings may provide a last major piece of a puzzle for a new way to store the sun’s energy – it could be a tipping point for a solar energy future,” added Meyer.

The discovery has paved the way for a new process called dye-sensitised photoelectrosynthesis cell (DSPEC). The Hydrogen is produced by splitting water into its components using solar energy. The Hydrogen fuel thus obtained after the split is isolated and stored. The oxygen is released into the atmosphere as a by-product. The system devised by Meyer made use of a molecule and a Nano particle. The molecule absorbed solar energy and infused the catalyst to break the electrons in water molecule. The Nano parti
