The Two Extremes of Waste Management in Chennai

Chennai city is doing great in terms of waste water management / sewage treatment, managing to get recognition from the prestigious United Nations. However, on another note the problem of e-waste is looming the city and is growing to be a matter of serious concern.

Solar energy

Solar energy refers to the energy derived in form heat and light from solar radiations. This is one of the best renewable energy source provided by nature. It is available abundantly (3.8 million exaJoules).  Solar energy is one of the best forms of alternative energy available to mankind and serves as mitigation for addressing concerns on climate changes, greenhouse emissions and pollution.

Solar technology develops methods by which solar energy can be harnessed into usable forms like power, heat and thermal applications. The applications of solar technology are solar water heaters, traffic lights, solar cookers, power plants catering to smaller community, solar cars to name a few.

Solar technologies will boom in the upcoming years due to the environment green initiatives. In the modern world, solar lighting is preferred way of illuminating large buildings like office spaces, airports and shopping malls. This reduces cost of power and makes the environment sustainable.

Applications with solar technologies will be the future as there will be significant thrust in investments from both the government and corporate sectors. Prices may come down due to new entrants and interest in alternative energy production. One can expect significant breakthrough in research and inventions of solar applications as many countries are already investing on this form of energy.

MNRE to introduce quality check system for solar products

The key question of course is whether MNRE has the required expertise within itself for preparing such benchmarking procedures. While it might seem simple enough, panels and inverters could get rather complex if one starts getting into the micro details. Which is why I will be interested to know if India has expertise enough to prepare such quality benchmarks. Not that it is too much of a problem if we don’t – the Germans are always there to help us, and if one were to go by the number of German companies present at Intersolar, access to these experts should hardly be an issue!

If diesel is a necessary evil, make the most out of it – through CHP

Through what in industry parlance is known as CHP, or combined heat and power. Essentially, what you do is that you capture the exhaust heat that comes out of a diesel genset and utilize this heat either for industrial heating or drying purposes, or, through a vapour absorption machine (VAM), convert this heat to cold for air-conditioning or cold storage or whatever.

Intersolar – And the Bandwagon Chugs On?

One would have thought the solar fatigue would have set in. Heck, who would like another solar show in which the usual suspects (in order words, people like me), spoke the same faded and jaded words!Somehow, the just-concluding Intersolar edition 2011 at Mumbai appears to have done a decent job. The conferences were reasonably well attended, and the parallel exhibition had over 250 exhibitors.

Discovery of a ‘dark state’ could mean a brighter future for solar energy

The maximum theoretical efficiency of the silicon solar cell in use today is approximately 31 percent, because much of the sun’s energy hitting the cell is too high to be turned into usable electricity. That energy, in the form of “hot electrons,” is instead lost as heat. Capturing hot electrons could potentially increase the efficiency of solar-to-electric power conversion to as high as 66 percent.

New record voltage for organic solar cells opens the tech to consumer electronics

Molecular Solar Ltd, a spinout company from the University of Warwick, has achieved a significant breakthrough in the performance of solar photovoltaic (PV) cells. They have achieved and demonstrated a record voltage for organic photovoltaic cells that means these highly flexible, low cost solar cells can now be devolved for commercial uses in a wide range of consumer electronics.
The Company’s most recent advance in the development of its organic photovoltaic (OPV) cell technology is the realisation of cells with open-circuit voltages in excess of 4 volts for the first time. Molecular Solar’s research team believe this is a record for an OPV device. Dr Ross Hatton, Research Director of the company commented:
“This is an important advance. We are now very close to having highly flexible organic photovoltaic cells that will be capable of delivering electrical energy at a voltage suitable for recharging lithium ion batteries that are widely used in portable consumer electronics. Remarkably, this high voltage is achieved using a cell with only 4 junctions (sub-cells)”.
University of Warwick researcher Professor Tim Jones, who is Chief Technology Officer of Molecular Solar, added: “The first generation of organic photovoltaics will be exceptionally well matched to consumer electronics applications. The advantage of Molecular Solar’s high voltage cells is that a single cell can be used with no requirement to connect multiple cells in series for these applications, saving manufacturing cost.”
Andrew Oldfield, Head of Cleantech at Mercia Fund Management said, “We were attracted to Molecular Solar’s unique approach to realizing truly flexible, environmentally sustainable photovoltaics that are well matched to the burgeoning portable consumer electronics market.”
Molecular Solar are currently finalising a £5m investment round to complete the up-scaling of their OPV and MS-Flexifilm™ electrode technology.
