Solar Energy Organization of Indian to create India-centric technology and products

CHENNAI: The state-run Solar power Energy Organization of Indian is planning to set up small, head power vegetation with powerful linkages with analysis and educational organizations to create systems and items appropriate for Indian.

"We need to put up display solar systems, say, of five MW of two or three adjustments in a solar recreation area and gather the data for climbing them up. The solar recreation area will be close to R&D (research and development) systems and educational organizations," Anil Kakodkar, chair of the business, informed correspondents in an appointment.

He, however, dropped to reveal the potential places where such recreational areas would come up.

Kakodkar said the business would put up solar vegetation on its own.

"We are looking at focused sun vegetation while there are other options also," said the former chair of the Nuclear Energy Commission payment.

He said there is a probability of having large solar enthusiasts that would move direct natural light to be lastly gathered into a photovoltaic or pv component. Another technology is having a variety of a structure and photovoltaic or pv showcases. The reflection would indicate the natural light on a structure which would stream the light back to a photovoltaic or pv section on the earth.

Kakodkar said Indian should have a long-term ideal strategy for maintainable growth of the solar market while being aware of the need to do value addition within the nation.

One of the components of such a ideal strategy is to reduce the cost by creating systems and items that are India-centric.

"For example in Indian the dirt fill on solar power sections are great. In Rajasthan, the sand contaminants on the sections are great. We have to see how the dirt fill on sections could be reduced," Kakodkar said.

On the items side, he said the nation should look at the likelihood of taking solar lantern production to the bungalow market level that would produce tasks in non-urban areas.

Verizon iPhone antenna redesign may thwart 'death grip,' says expert





Apple has redesigned the iPhone 4's antennas for Verizon, perhaps to foil the "death grip" problem that roiled AT&T customers last summer, an expert said today.

"They've moved things around, and my guess is that they went to a dual antenna," said Spencer Webb, an antenna engineer with nearly a dozen patents to his credit, and president of AntennaSys, a mobile device antenna design and consulting firm.

Webb was reacting to photographs that have been published on the Web which show a different configuration for the slots in the external stainless steel frame, which houses the phone's antennas.

Shortly after the introduction of the AT&T iPhone 4 last summer, customers complained that holding the device in certain ways or touching it in specific spots lowered signal strength and dropped calls.

Experts, including Web, explained at the time that placing part of one's hand over a slot degraded performance by bridging the separate antennas, changing the length of the cellular antenna and thus its ability to receive and transmit.

The iPhone destined for Verizon has four such slots, one near the top, the other near the bottom on each side. The original iPhone 4 sported three slots, one on the top, and one low on each side.

Based on the number of slots and their symmetrical position, Webb speculated that the Verizon iPhone has two identical cellular antennas. Covering a slot on one side of the new iPhone may hamper reception, but the phone should still be able to receive and transmit properly as long as the other isn't similarly bridged by a finger or palm.

"That looks like it's a possibility," said Webb, who like everyone prior to Feb. 10 when Verizon's iPhone goes public, was taking an educated guess. "Apple might have done something clever here by scrambling to come up with a better solution, two cellular antennas."vApple has redesigned the iPhone 4's antennas for Verizon, perhaps to foil the "death grip" problem that roiled AT&T customers last summer, an expert said today.

Shortly after the introduction of the AT&T iPhone 4 last summer, customers complained that holding the device in certain ways or touching it in specific spots lowered signal strength and dropped calls.

Others have also said that Verizon iPhone has multiple cellular antennas.

The technology site AnandTech, which was among the first last year to quantify the signal loss of iPhone 4's "death grip," said that Verizon requires dual-receive antennas for devices that access its network.
