Laser is supposed to make lightning from thunderclouds harmless

laser is supposed to make lightning from thunderclouds harmless

A european research consortium wants to use a specially developed laser to extract lightning from thunderclouds and make it harmless. The device, which can emit 1000 laser flashes per second with up to 600 gigawatts, was presented in unterfohring near munich, germany.

It was built by trumpf scientific lasers, one of seven project partners. The basic idea is to use the laser to create a plasma channel in the air. This channel conducts electricity very well. That’s why lightning follows it, as the managing director of trumpf scientific lasers, knut michel, explains. "For the blitz, it’s like choosing to drive on the highway or to fight your way through the jungle."The plasma channel, which is to be at least 100 meters long, is laid out in such a way that it guides the lightning to a classic lightning conductor that renders it harmless.

The technology could be interesting for airports, for example, so that they can maintain operations during thunderstorms or to protect sensitive objects such as missile launch pads from lightning strikes. "The damage caused by lightning runs into the billions every year," says michel. Especially in the case of airports, the times when they had to be closed because of the danger of lightning strikes were very significant.

Bamberg bus driver protects passengers from rioters

Bamberg bus driver protects passengers from rioters

It's the first round after the break, when uwe smola (51) is on the bus on this 5th day. April 2017 gets into his city bus. Line 910 in the direction of michaelsberg, 16.05 o'clock. Smola still knows exactly. Also what happened next: "there was a brawl at the ZOB, the police were already on the scene. Two of the group wanted to get on my bus, so I quickly closed the doors."

But because an elderly couple still wants to get on, the city bus driver opens the door again – and the two young men scurry inside. "I told them to get their act together." At first, everything had been in order, they had dutifully paid their ticket.
Then, shortly after the stop "am kranen", one of the two completely freaks out. The 21-year-old bangs on bus poles and seats, attacks passengers. "He grabbed one of them by the collar and threatened: "if you open your mouth, I'll punch you in the face", reports smola.

He observes the situation in the rearview mirror, sees how the 21-year-old starts to harass a teenager. "The atmosphere was very tense, people wanted to get out of the car. I immediately stopped at the next stop in markusstrabe." He asks the two young men to leave. "One of them suddenly rushed forward, destroyed a ticket validator and yelled at me: "don't throw me out!!"

Weismain daycare center children make a “color tree

Weismain daycare center children make a

Sometimes the result is not so important and the way to get there is much more interesting. At first glance, you see the "color tree in the daycare center"s "kinderzeit" area the work that went into it; even the director, elfi bienlein, admits that "it wasn"t an aesthetic art project." the children"s months of hard work, especially with the leaves and their materials, were rewarded with a prize in the "it works" technology competition?!".

"Our goal is to let the kids experiment and go their own way", explained stephanie votter from munich, the project manager of the competition organized by the bildungswerk der bayerischen wirtschaft (educational association of the bavarian economy). The fact that this guideline was taken to heart at the weismain daycare center was underscored by a presentation of more than 270 pages, with which elfi bienlein explained the creation of the "color tree" to parents and representatives from business and politics the picture show revealed how it all began before winter with the cutting of apple trees in the nursery garden, when the children wanted to use the branches for the new project; it showed how the children, experienced in building mud huts the previous year, switched to willow as a material – and then spent weeks decorating the finished tree next to the soccer hall with leaves. "Paper softens up", the 44 girls and boys realized by trying them out, even cardboard leaves couldn"t withstand the weather.

And so they made their own suggestions, which led to ever new materials: they learned how to use the hole punch to make leather leaves, those made of wood and iron led them to a carpenter's workshop and to a metal designer; when dealing with glass as a raw material, they got help from an optician and discovered that cullet is no longer sharp when it is boiled.

Russia’s most modern jet lost in indonesia

russia's most modern jet lost in indonesia

Up to 48 passengers were on board the suchoi superjet 100, said the head of the indonesian aviation authority, herry bakti singoyudha, in jakarta. "We are still looking for it," he added. "We don’t know what happened."Bad weather initially hampered the search from the air.

An unnamed russian aviation expert said there was little hope for a happy outcome. He spoke of 44 occupants. There were 8 russians and 36 representatives of indonesian airlines on board the aircraft. According to information from jakarta, there were 40 indonesians and eight russians. Two helicopters aborted the aerial search as heavy clouds and strong winds hampered their flight, according to officials.

The plane disappeared from the radar screen in the area of the 2200 meter high volcano salak near the capital jakarta, singoyudha said. Shortly before, the crew had asked to be allowed to reduce the flight altitude from 10,000 to 6,000 fub (about 3,000 to 1,800 meters). A spokesman for the russian aviation consortium OAK confirmed in moscow that the radio link with the plane has been severed, reported the agency interfax. A spokesman for the russian ministry of industry said the aircraft had been inspected before the flight and found to be technically sound. "They made two demonstration flights," said adang surpiyadi, commander of halim military airport in jakarta. Contact with the plane was broken only about twelve minutes after takeoff on the second flight. There were reportedly no problems on the first flight. The local television station trans TV reported that one of its reporters and a cameraman were also on board. The aircraft was on a demonstration tour of six asian countries, it continued.

Siemens healthineers wants to grow with ki

Siemens healthineers wants to grow with ki

Siemens healthineers aims to achieve sustainable growth with modern imaging, remote operating room transmission and the increasing use of artificial intelligence in medicine.

In the medium term, the medical technology group aims to increase sales by five percent per year and earnings per share by ten percent per year, as announced by group ceo bernd montag in erlangen.

In the past fiscal year 2018/2019, the company, with 52.000 employees, sales jumped from 13.43 billion euros to 14.52 billion euros. Profit after taxes rose from 1.28 to 1.59 billion euros. But healthineers slightly missed profitability targets. The reason for this was start-up difficulties with the new atellica laboratory diagnostics system. The group expects profits to continue to rise in the coming years thanks to good business with so-called imaging processes. However, growth was allowed to slow down compared to the fiscal year just ended. The share price started trading with a jump of more than five percent.

New cell phone speed camera: netherlands uses new technology – is germany following suit??

  • Cell phone speed camerasnew device in the netherlands
  • The decisive factor is the location of the frame
  • Who is caught, must pay a high fine
  • When does germany follow?

Writing a quick message, checking the results in the sports app, or just looking at the navigation system: we all know that it’s illegal to use a cell phone behind the wheel – but many drivers still pick up their smartphones too often while driving. This often has consequences: according to accident statistics, one in ten serious accidents in germany can now be attributed to the use of smartphones. Even dead drivers are no rarity. The netherlands now wants to do something about it – with a cell phone speed camera.

Cell phone speed cameras: new device in use on dutch freeway

The pilot project starts on 23. November on the A28, the freeway from utrecht to groningen. It is considered the most important north-west connection in the country. On a 23-kilometer stretch between utrecht and amersfoort, the dutch police are now planning to introduce the "cell phone speed trap test. This marks the end of a one-year trial phase – the technology is now to be used in everyday life for the first time. In germany, the decision of a popular radio station had led to a broad discussion about speed camera messages: they threw the message about speed cameras out of the program.

West german radio reports that an algorithm makes it possible to identify traffic participants whose actions are suspicious. Artificial intelligence is to be used in the future to record all drivers who are likely to be using a cell phone at the wheel. According to adack, the technology can also detect tablets or navigation devices.
