Charging the mobile phone calls when radiation is douzeng?

According to foreign media reports, the United States 50 engineers at the University of Maryland after two years of arduous research, creating a human-driven helicopter, drivers push the pedals you can power the aircraft, will today (12th) test into the sky. History of human flight, has not yet successfully tested human helicopter, 1994 a Japan Human helicopter engineer flight test, but only about 0.2 m from the ground where flew for 19.46 seconds.

12th, if this human helicopters could fly over to 3 m high, and stays in the air more than a minute, then the University of Maryland’s engineers will be able to win the Sikorsky prize of US $ 250,000 (Sikorsky Prize).

Sikorsky prize is a United States helicopter society (American Helicopter Society) which was established in 1980 to encourage engineers research produced the first human-driven helicopter.

Human helicopter does not like ordinary aircraft with fixed wings. Only by constantly push pedal, pilots to achieve enough thrust fly on the sky.

United Kingdom Manchester University Antonio feilipuli (Antonio Filipponee) said: “If there is a fixed wing, only needs to provide forward thrust of aircraft to aircraft can be launched, because the fixed-wing itself upward lift will be provided. But the helicopter does not have a fixed wing, so at least 15 times times greater than normal aircraft power to take off, this is a great challenge. ”

Engineers at the University of Maryland to produce this human helicopter also has a name called “beauty”. “Beauty” fuselage 18.29 metres long, each rotor is 12.8 meters in diameter, placed on the ground about a standard football field area, one-third, but only 63.5 kg in weight.

12th, 24 year old biology student Judy-weikesile (Judy Wexler) will drive the aircraft into the sky. She has been selected, is because the weight is light, but it is also a cyclist, physically very strong.

Lenovo will push the new battery technology: 30 minutes charging 80%

News that Lenovo launches ThinkPad X1 ultra thin notebook. This laptop will use the new battery technology. A distributors by leaked documents showed that X1 notebook computer does not support user replaceable battery, but it provides longer battery life, can achieve a common battery three times before, and its charging speed is faster than the Lenovo laptop batteries before 2.5 times. This is mainly due to battery for X1 were named “RapidCharge” technology, this technology will allow X1 to be completed within 30 minutes charging 80%.

Lenovo to distributors in a PDF document introduces X1 battery technology:

-Products with new battery technology

-For super thin product design

-Relatively traditional laptop battery, battery life up to times 3 times

RapidCharge technology-X1, 2.5 times faster than previous ThinkPad battery faster charge, 30 minutes to fully charge 80%

-The user cannot replace the battery

-The built-in battery diagnostics tools monitor battery situation, including temperature, usage and time

-Need to be replaced by trained technical staff battery

New laptops will mainly compete with lightweight MacBook and 9,000 new Samsung notebooks are expected soon in Australia listed.
