Washington, September 28 : Mechanical engineers at the University of Strathclyde''s Energy Systems Research Unit (ESRU) in Scotland is developing a dual-rotor turbine connected to the seabed by a cable that rides the tide like a kite on a windy day.

According to a report in Scientific American, the ESRU team''s goal is to create a device that literally goes with the flow rather than resting on the sea bottom like an underwater windmill - a model already being developed by a handful of companies. 

The kite and cable model is designed to facilitate placing tidal turbines in deep water, where the stronger current has the potential for providing reater power but also makes it extremely difficult to plant a turbine in the seabed.

Washington/Tel Aviv - The United States has transferred to Israel a high-powered radar system that will improve Israel's reaction time to a possible Iranian missile strike, the Defense News magazine reported over the weekend.

Quoting US and German sources, the magazine said that more than one dozen aircraft transferred the X-band radar system and some 120 supporting personnel and equipment to Israel on September 21.

The high-powered, high-frequency system is designed to detect and track ballistic missiles soon after launch and can track an object the size of a baseball from 4,700 kilometres away.

Washington, September 28 : Researchers from Maastricht University in Amsterdam have found a possible solution in dealing with the increasing tourism in Antarctica that can form a threat for the vulnerable South Pole area, in the form of marketing the visitor rights to the highest bidder.

Tourism in Antarctica has grown dramatically. In 1985, just a few thousand people visited the area but in the season 2007/2008 more than 40,000 did the same.

A number of parties are concerned about the effects of this rapid growth with respect to safety, the environment, the scale of tourism and the lack of financial resources for monitoring and enforcement purposes.

Peshawar, Sep 28 : The United States is getting ‘good actionable intelligence’ on al Qaeda in Pakistan’s Tribal Areas but not the Taliban, said a senior official co-ordinating with Washington in the War on Terror.

“The US has good intelligence on al Qaeda members in Pakistan’s Tribal Areas, and Washington also appears more interested in Qaeda than Taliban,” the senior official said, asking not to be named.

The killing of Abu Khabab al-Masri, head of al Qaeda’s weapons of mass destruction programme, in the first week of August in South Waziristan speaks volume for the good intelligence the US is getting.

Washington, Sept 28: President Asif Ali Zardari has denied that US and Pakistani forces had exchanged fire along the Afghan border this week, even as the chairman of the US Joint Chiefs of Staff acknowledged the two sides engaged in a brief firefight.

The Washington Post quoted Zardari as saying that Pakistani border forces shot warning flares on Thursday at two US helicopters that he believes inadvertently crossed into Pakistani territory from Afghanistan.
