All transparent solar cell engine glider cockpit

A German university students completed a very nice green aircraft design, although the aircraft was a glider, but with a motor. This design won the Lucky Strike for his company’s 2008 Young Design Award winner.

Fuselage and the wing is very light weight, and covered with solar panels. Large area of solar panels, combined with very light body, so you can make it without additional power or fuel to be flying in the sky. For insurance, the fuselage also comes with a spare fuel engine. Fully transparent polycarbonate produced by the body, it is easy to reuse in an environmentally friendly material.

Large energy storage battery

Our first year of successful operation of large energy storage battery trouble

Dalian on July 15 news 376 days, which is today fuel cell floor, digital LED screen. This indicates that the development of our country by the first demonstration vanadium flow battery energy storage system, with no trouble continuous operation for over a year, indicates that China has all vanadium flow storage batteries made important progress in research and application is expected to break large-scale electrical energy storage worldwide problem.

All vanadium flow storage batteries LED screen model system, researchers led by the Zhang Huamin independent research and development research group. The core is rated output 2 kW vanadium redox flow battery system. After more than 9,000 hours of test, no cell system output performance degradation, power supply stability, and lasting. Hua-Min Zhang said: “This shows we have achieved stability and durability of the new battery, the current international and only Canada, Japan, a similar technique to master.”

In the vanadium flow battery power systems, Hua-Min Zhang and his team also made a major breakthrough, the first generation of 100 kW-class vanadium flow battery energy storage system has been completed design, integration and debugging. This is the largest flow battery energy storage system. Preliminary tests, the 100 kW output power, the battery charge and discharge energy conversion efficiency of over 78%, far higher than is now widely used lead-acid battery to 50% conversion efficiency. Through further optimization of the battery output performance can be further improved.

Vanadium redox flow battery is known as “power bank.” Vanadium redox flow battery energy storage in the scale of the energy conversion efficiency has a high charge storage capacity, operational safety and environmental friendliness. It can be used to power “off peak to valley” of regulation, reduce the cost of power generation, improve energy efficiency; for solar, wind and other renewable energy power storage, power generation to resolve their instability, discontinuous and Nan Yi grid-issue; also an important sector and equipment can be used as backup power plant.

Buy a new cell phone battery requirements for the issue no one to turn

Just bought a few days of phone problems, find malls, find counter dismissed, according to the address found on sale card service stations, service station to find the door locked.

June 26, Ms. Chen arrived in Hankou New Pageant Place, spent 799 yuan to buy a phone, would have thought that after 12 hours of charging cell phones, but less than a day standby. 28, Ms. Chen arrived in stores, ready to look for counter consultation, but found that counter actually invisible, and one asked around, counters have been evacuated. Subsequently, Ms. Chen to the phone cards on sale to the telephone hotline to fight, but has no answer. Left with no alternative, Ms. Chen wrote on the card according to after-sales service centers address in the Jianghan Road, a building to locate the service station, but to eat the cold shoulder. “Such services, how to retain customers?” Ms Chan said angrily.

Yesterday, Ms. Chen received the complaint, after-sales hotline’s call remains unanswered. Through online inquiry, the reporter and away the mobile phone manufacturers in Shenzhen to get in touch, through a telephone, through three inquiries before and after-sales department in the Chinese manufacturers to get in touch.

For this situation, manufacturers of a person in charge explained that the agreement in the Chinese aftermarket company changed, causing inconvenience to customers, sorry, will certainly give customers a satisfactory argument.
