The Race To Harness Himalayan Hydropower

Spend a day in Kathmandu, Nepal's sprawling capital of 4-million people, and you'll quickly notice what has long been a fact of life in this landlocked Himalayan country, and many other South Asian nations - no reliable electricity supply exists.

Up to eight times a day, neighborhoods throughout the city suffer rolling power cuts due to load shedding, causing residents and businesses alike to either carry on in the darkness, or rely on expensive, diesel-consuming generators to keep the lights on. Although the country's civil war ended in 2006, carrying the promise of restored domestic stability and accelerated economic development, Nepal's economy has remained hamstrung by an inconsistent energy supply, with only 40 percent of the population having access to electricity. This situation persists despite the fact that the country sits on top of a virtual goldmine - an estimated 80,000 megawatts (MW) of untapped hydroelectricity, of which it has harnessed a scant 700 MW.

Nepal's great untapped hydropower potential has not gone unnoticed. Neighbors India and China actively have courted the country for years, seeking dam construction contracts and energy export deals to help meet their own soaring domestic energy needs. But while some Nepalese hydroelectric projects have moved forward, some of the country's more ambitious hydroelectric development plans have been delayed or scrapped altogether since 2006, owing to Nepal's notoriously fractious internal politics, and persistent social unrest near proposed dam-construction sites in rural areas formerly sympathetic to the Maoist insurgency. One reason for the impasse surrounding many major hydroelectric projects is that Nepal has long been wary of foreign meddling in its internal affairs, which has meant that Indian and Chinese efforts to bankroll major infrastructure projects are automatically viewed with suspicion.

India and China have become locked in competition to ink construction contracts in Bhutan and Burma as well, two countries similarly spanned by the Himalaya that possess substantial undeveloped hydroelectric resources. Bhutan and Burma have both embraced the idea of heightened hydroelectric development, reflecting a different attitude than Nepal's regarding both energy infrastructure and foreign contractors. Bhutan would benefit greatly from increased domestic power production, given that it now uses only 390 MW of its 30,000 MW hydropower potential (or 1.3 percent). Even at that modest level of development, hydropower has already emerged as one of the mainstays of the Bhutanese economy, alongside tourism. However, the country currently lacks the technical resources to further bolster its hydroelectric capacity, a vacuum that state-owned Indian energy firms have rushed to fill. Indian firms have competitive advantage over in China in this regard, as Chinese-Bhutanese relations have remained tense over the years due to persistent quarreling over contested border areas. As a result, many of the country's high-profile hydroelectric projects - such as the 2,500 MW Sankosh River Hydropower project, slated to become the world's fifth tallest dam upon completion in 2016 - are contracted to Indian companies.

Burma, meanwhile, represents one of the last major untapped sources of hydroelectricity in South Asia. From Burma's point of view, developing energy resources in the country's mountainous north - where many proposed hydroelectric sites lie - is strategically important for two reasons. Firstly, developing some of the country's estimated 40,000 MW of hydroelectric potential would help shore up domestic energy supply in this country of 54 million, which is slated to grow to 61 million by 2025, and nearly 71 million by 2050. Currently, Burma has harnessed only 2,440 MW, or six percent of this potential. Secondly, excess hydroelectricity produced in this region could be sold to consumers in adjacent Yunnan province (China) and Assam state (India), two economically underdeveloped regions bordering Burma that would benefit greatly from a more reliable energy supply.

The compressed air powered AirPod

The Tata AirPod is a city car running on compressed air (as well as a battery-powered electric motor). The ease of converting air into an energy source using simple compressors means charging stations can be placed anywhere, and they require no provisioning — no trucks delivering gas, ethanol, or hydrogen — and they produce no emissions, just discharge of the air.

The AirPod can run 125mi (200k) at a top speed between 28 to 43mph (45 to 70kph). The car is intended for a single rider, and has a small cargo area in the back.

An amazing affordable auto that runs on air! AIRPod is the culmination of MDI studies on pollution and urban mobility. This concept will be the first to leave the production line in spring 2009. MDI will respond to an invitation to tender of the city of Paris, "Autolib'", and is already the subject of applications for various municipalities. With small size, a tiny price, zero pollution, fun and futuristic design, AIRPod mark a turning point in the range of urban vehicles while renewing the idea of the automobile and transportation. You can drive with a joystick, it only costs one euro per 200 km and leaves no one indifferent in crept in traffic. It is a real breath of fresh air in our cities and the prelude to travel without pollution. Its small size make it easy to park, keeping still a large internal volume. AIRPod help us to forget the price of petrol. AIRPod is part of the MDI production licence of "less than 500kg vehicles", and is manufactured in the same factories as OneFlowAir, following the original production concept proposed by MDI. AIRPod The standard version is designed for the transport of persons. It has four seats (3 adults and one child) and has space for luggage. It is dedicated to multiple uses as in the private and public sectors. Airports, train stations and municipalities also need a cheap, non-polluting car with high mobility. This wehicle is changing our urban life in the city center in freeing ourselves of the prohibitive cost of petrol

Pre-feasibility report: Islamabad asks WB to weigh up power import from India

ISLAMABAD: The World Bank has begun preparing a pre-feasibility report to assess the viability of Pakistan importing power from India under the Pakistan Regional Trade Programme, a senior water ministry official told The Express Tribune.

The World Bank’s initiative comes in light of the request made by Pakistan to provide technical assistance to conduct a pre-feasibility study regarding the import of power and exploring interconnection options between the power systems of both nations.

The study will help Pakistan in identifying issues and important risks of the proposed interconnection and electricity trade. It will be evaluated by a committee of experts from the National Transmission Dispatch Company and the Ministry of Water and Power. The official said negotiations among various stakeholders regarding the possibility of interconnecting power grids are ongoing.

Pakistan had decided in April that it would import up to 500 megawatts of electricity from India with the World Bank agreeing to fund construction of the required infrastructure. “We will import 500MW from India initially. Import can be increased up to 5,000MW if our need so demands,” said the ministry official.

No transmission link currently exists between India and Pakistan. It was decided earlier that the countries will build a 45-kilometre, 220 kilovolt transmission line within six months of signing a formal agreement. The agreement will be valid for five years, after which it can be extended for another five years. More
