Prof. Seamus Garvey will Store wind for power generation
Everyone knows about wind mils. Sri Lanka also have few of them. But do you know about store the wind for power generation, specially undersea. Wow Professor Garvey, from the University of Nottingham has come up with this idea and Power company E.ON has granted 300,000 euros (£236,000) towards building two prototypes.

A bad news for Al Gore - A giant slab off in Antarctica's Wilkins Ice Shelf
“Wilkins is the largest ice shelf on West Antarctica yet to be threatened. This shelf is hanging by a thread,” said David Vaughan of the British Antarctic Survey. Now a large part of the 12,950-square-kilometre shelf is supported by a narrow 5.6-km strip of ice between two islands
The shelf was triggered February 28 when an iceberg measuring 41 by 2.4km broke off its southwestern front. The effect is nicely shown above picture.

Study on the potential of Biogas in Sri Lanka
The author is Prof. Ajith de Alwis and the publisher is ITDG South Asia. The author discusses a study on electricity generation potential from biogas derived from diverse source of biodegradable waste. This book contains very important topics on biogas generation such as estimation of biogas potentials and energy potentials from some selected waste streams, energy equivalent of biogas, guide on raw material selection, process stoichiometry, pathway reactions and corresponding enthalpy, district wise energy potential from livestock from waste, turning human waste into energy, biogas potentials from industrial wastes [food and beverage industry, brewery and distillery, sugar, leather industry, desiccated coconut sector, rubber industry … etc], Biogas technologies for Sri Lanka.
This comprehensive study is done under interest and support of ITDG and Energy Forum Sri Lanka. This book is published with the aim of informing regional and national policy makers and the interested public on biogas options in

India's growing gender imbalance
In ancient India girls were face troubles after their birth. But now with advancement on medical technologies they are endangered even as a female foetuses. Because a simple Scan will tell the parent about sex of their foetuses. Indian people do not like girls to be as there children because of financial burden, largely because of the dowries that have to be paid.
Source: Al Jazeera
"India is facing a growing gender imbalance -blamed on the widespread abortion of female foetuses. In some states, fewer than eight hundred girls are born for every thousand boys. Girls are seen as a financial burden, largely because of the dowries that have to be paid when they get married. Now the Indian government will start paying parents to help them bring up female babies." - Al Jazeera's Matt McClure reports

'white space' wi-fi
Google is pressing US policymakers to allow to use unlicensed frequencies of TV which is called white space as wi-fi network. Great if this happen in Sri Lanka dialog or mobitel will able to provide a handsome wi-fi service across the nation. Every home will be covered by wi-fi network.
We will hope success for google's effort. Once it become reality in America we will soon gain it in Sri Lanka also.

"Food prices rising across the world" - CNN - Why this happen?
Petroleum prices, which increase the cost of everything from fertilizers to transport to food processing - [Solution: Do not addicted to fossil fuel, go for alternative fuels. ]
Because of Biofuels extraction from food items such as cassava, wheat starch, rice starch. [solution Try to use non-food bio resources as renewable energy sources. when you develop biobased fuels. Ex. Biogas, Solar, .... etc ]
Due bad weather and poor harvests have a bigger impact on prices. [Solution: Minimize environmental pollution and try to avoid climate crisis.]
Above reasons are global. According to my point of view in Sri Lanka we have another reasons for food price hike. In sri lankan normal economic pattern we do have many intermediate vendors in between customer and farmer. Post harvest damages on food is huge [approximately 20%] and most of food items specifically vegetables and fruits are damaged in transportation. Most of sri lankan used to buy every thing from market while they have enough space and time to maintain a home farm garden to cultivate essential vegetables and food items. I think this is one and main method to fight with increasing food prices. Another improtant thing is we must ensure food security in country and we must promote local production of essential food items. We must change the centralized food item distribution culture [Dambulla and Collombo market] and we must develop a distributed network to transfer food items in between farmers and customers.
We must take this problem serious. Every one should think to do there best. I think with this will cause more hunger deaths world wide. [Read about huger deaths]

Some important points in CP implementation on Energy application. Can You suggest more?
• Proper insulation on heating and cooling systems and pipe networks.
• Using more energy-efficient equipment
• Continuous maintenance aiming optimize energy usage in equipments
• Ensuring optimal combustion in hot water boilers and steam boilers
• Eliminate steam and condensate leakages and discharges. (Do not waste condensate, it contain more heat comparatively to make up water of the boiler)
• Using low-grade energy for use elsewhere in operation, such as using furnace emissions to heat up make up water stream.
Are there more options? Can you suggest with your experiences?

The family of Sri Lankan blogosphere got a new member www.slblogs.org. It is in developing state and now syndicate 48 blogs. I add my blog also. But still my blog is not added with them. I hope they will soon add my blog with their directory. According to Alexa.com reviews blogger.com is among top 100 list of sri lanka. [see the top 100 website of Sri Lanka] It has listed in 9th place today, but it fluctuates.
This feature prove that there are many bloggers in Sri Lanka. So Sri Lankan blog agitator is a vital to make them collective. kottu.org and Achcharu are doing good service.
