If you are a fan of medical films, then you will know there are emergency helicopter services that will take badly injured patients to hospitals long distances away. You probably also know that in these films most ambulances (救护车) are on wheels and go across city streets where there are fewer traffic jams than in real life.

But now, Israel’s Urban Aeronautics, announced that it made an agreement to work with Hatzolah Air to produce and develop its CityHawk aircraft as an emergency medical service. The CityHawk is small and can fly anywhere and land anywhere, making it able to work in cities above the traffic jam. It has no wings outside and can work even in bad weather conditions.

“We are excited to work with Hatzolah Air on the development of our CityHawk vehicle,” said Rafi Yoeli, CEO of Urban Aeronautics. “Its small size will enable it to land in the middle of a busy city street, making it a perfect fit for medical tasks by greatly reducing the time it takes to arrive on-scene, treat and transport sick or injured patients to medical facilities.”

“One of Hatzolah’s most important goals is to be somewhere within minutes. Unlike helicopters, we can land anywhere within minutes,” Yoeli said. “We will be able to improve the care of patients. They want to be equipped with the best aircraft.” Hatzolah Air’s president Eli Rowe said that he foresees (预测) the possible need for 800 CityHawks since it is a six-passenger vehicle that can carry a pilot, a patient and a team of professionals.

Urban Aeronautics is working on certification (认证) for emergency use of its CityHawk aircraft. The development of the flying ambulance is expected to take up to five years but a model will be ready sooner. A flying ambulance may be coming to a city near you soon.

"Developed and developing nations can learn from each other seeking a low-carbon economy. In terms of energy saving and green economy, China doesn't lag behind developed nations," said Zhou Changyi, director of the energy saving department of the Ministry of Industry and Information Technology.

"While we can learn many aspects from developed nations, they also should learn something from us, such as water conservation," Zhou said in a speech during the new Path of China's    Industrialization forum at the ongoing China International Industry Fair.

Tobias Becker, head of ABB' s process automation division for North Asia and China, said LCA is an effective tool in helping manufacturing industries to reduce carbon emissions.

LCA shows that industrial customers should focus on a product's environmental impact throughout its life-cycle instead of on its initial investment.

Richard Hausmann, North East Asia CEO of Siemens, said, "The color of future industrialization is green. "

The Germany company recently announces that it wants to receive orders worth more than 6 billion Euros ( US 8. 8 billion) for intelligent power networks, Smart Grid, over the next five years. Siemens has set a 20 percent market share target for the global smart grid business.

A smart grid delivers electricity from suppliers to consumers using digital technology, advanced sensors specialized computers that save energy, reduce costs and increase reliability. The United States and China are considered the two biggest markets for smart grid.

A．Small in size

B．Low-cost

C．Energy-saving

D．Security

Most of us have been in this situation: You’re on your way to your friend’s house, then you suddenly ask yourself, “Did I remember to turn the lights off?” For those with “smart homes”, however, this wouldn’t be a problem.

Over the last few years,smart home technology has become more popular. Thanks to user-friendly products like intelligent lighting and heating controllers, people can control nearly every electrical item in their homes from anywhere in the world.

While smart homes aren’t new, companies like Philips, Amazon and Xiaomi have finally brought automation to everyday people with affordable products like artificial intelligence(AI) speakers and sensors.

“The obvious message is that you can stop wasting energy,” Tom Kerber, director of research for U. S -based digital company Parks Associates, told The Guardian.

And the technology also has more meaningful uses. In Norway, for example, one company is using smart tech to make life easier for its elderly customers. Abilia’s system allows carers to check up on patients through a tablet on a wall inside their home. The device sends patients reminders about tasks, such as when they need to take medication (冥想). It can even tell carers if there’s any unusual activity in the home that could be life-threatening.

“This kind of system allows people to take care of themselves, which is the most important thing,” Abilia’s vice president, Oystein Johnsen, told the BBC. “It also saves the government money. In Norway, it costs 1 million kroner(about 0. 8 million yuan )per year to have someone in a care home. This system costs 15,000 kroner a year.”

So, for those who have already “gone smart”, will it ever be possible to go back to do things in the old-fashioned way? “I think it would be difficult. When we go to a friend’s house or on vacation we find ourselves expecting the house to do things for us that we should do, ” Poulson, 35, a senior program manager from Seattle.,U. S.,explained.
