Google denies use of camera drones

The silent aircraft of the German company Microdrones be tested or used. Previously, the "Business Week had reported in a scoop of an alleged co-operation.

Google plans apparently do not use drones photographed for its card services. Spokesman Stefan Keuchel has denied a report by the Economic weeks now.

Google was not aware of any relationships with Microdrones said Keuchel the newspaper picture. "We are always looking for ways to improve our card services like Google Maps or Google Earth. As part of this effort, we explore many different technologies." Drones were tested but not yet used.

The German manufacturer had Microdrones Claimed to the economic week, are already in discussion with Google. "The UAVs are well suited to provide more timely recording of the map service Google Earth," said Microdrones boss Sven Juerss.

The unmanned aircraft are flying over a range of several thousand meters and a speed of up to 80 km / h automatically entire neighborhoods. This would allow Google to also inspect farms, which invest in the company just said Juerss. Google did not comment on the request of the business week.

Data protectionists warn meanwhile warned that the drones pose deeper problems than Google Street View. The planes are almost silent and penetrate undetected into areas that are not seen on photos from the road to even on conventional aerial photographs. Flying robots could shoot through windows, or supply images from gardens and balconies.

Juerss defends itself against the allegations, his drones were a ‘Big Brother of the Air’: "It had always been forbidden to enter by means of photography and film in the private sphere. Our Drones have changed this legal situation."

Fuel cell products made in China exported bulk

January 5 reports: Along with the "Water and Sustainable Development" as the theme of the 2008 World Expo closing of Spain, the Chinese fuel cell products in the international arena, the successful debut also drew the curtain.

Impression in people's past, the fuel cell is more of a veiled high-tech products, very green, very advanced, but still far from practical. A company called climbing the emergence of hydrogen energy industry to change this situation. Has now developed a series of fuel cell products, and has applied to the tour buses, bicycles, portable power and other occasions.

Bottlenecks due to technical restrictions, the domestic fuel cell in the past mostly as a demonstration purpose. Even if only as an occasional sample sales, and not a batch. The climbing equipment, the fuel cell industry, 21 electric bicycle export to Spain. Fuel cells and fuel cell products, though the sample is only one word, but the meaning is very different. As the product not only satisfied with the work to stabilize, and must have the durability, practicality, cost, appearance and other aspects as well as considerations. In addition for different markets, the relevant certification was necessary.

The export volume fuel cell products is another important significance lies in its purely domestic! This not only refers to the bicycle body also includes a key raw material in fuel cells: catalyst, membrane, carbon paper and the localization of bipolar plates. In which the catalyst and membrane by climbing industry independent research and development and production. Long been neglected domestic raw materials in the practical proof of its outstanding performance in par with international similar products. At the same time the localization of key materials, so often been criticized for the cost of fuel cells can be effectively controlled. Since most of the past, the key raw material to be imported, which makes the cost of the fuel cell control was clutched in the hands of foreign companies, the stakes just look at China's IT industry will be able to get some idea. As foreign enterprises to master the most upstream CPU technology, most IT enterprises has become an overseas Chinese enterprises assembly plant and the client, the price level determined entirely by the upstream firm.

Because these products excellent performance in Spain, climbing industry, the company's Spanish and Italian partner is actively planning for vehicles driven on public roads in the matter, in 2009 there will be more Chinese-made fuel cell products in Europe.

Power Lithium Battery Product Analysis

Has the "ultimate energy" and "green energy," said the lithium-ion batteries, since the 90s of last century since the advent of electronic products from the button batteries, cell phone, DC digital products in the lithium battery, the electric vehicle in the battery power, is increasingly widely used in people's production and life. Compared with other batteries, lithium-ion batteries on whether it is from the volume, weight, or from the performance, have a great advantage.

To use in a reasonable range of voltage within the capacity of lithium batteries, one-sided pursuit of large capacity, high voltage is wrong. First, any thing to go through a simple to complex, from hard to easy the process is also flammable like gas, effectively guarantee the safety of lighters is relatively easy, to effectively guarantee the safety of fuel tanks would much more difficult, crash is still not fully resolved the situation when the car caught fire and exploded. A limited volume in the more energy the more the accumulation of bad management, is currently the largest in Suzhou Star 48V10Ah constant can only guarantee the safety of the battery combination. Second, the higher the voltage, the greater the capacity, protection circuit and a balanced circuit the greater the difficulty and failure rate, so do not advocate Suzhou Star constant and does not support beyond 48V10Ah battery combination.

Depends on the safety of lithium battery testing and certification

A, UL certified

Today, most countries and regions in the world involving security, health, environmental protection projects such as product requirements must be obtained before entering the market, the safety certification. UL mark has become world famous one of the safety certification mark.

Testing standards are as follows:
