In addition, ART does not need any rails. Instead, it is based on built-in sensors only on a white dashed line on the ground. This is also the decisive advantage of this new type of track.

The construction of a metro including rails costs between 400 and 700 million yuan (52.29 million and 91.5 million euros) per kilometer. The construction of an ART costs only about 15 million yuan (1.96 million euros).

“There is a huge demand for urban transit systems,” the company said. One reason for this is the steadily growing urban population. The first real use of ART is planned in 2018 on a 6.5 kilometer stretch in Zhuzhou, north of Hong Kong.

Daimler and Bosch Want Driverless Taxis Already in Five Years

A “series-ready system for driverless cars in public urban road traffic”: Daimler and Bosch want to bring this together to the market by the beginning of the coming decade.

Originally in 2030, everything was going to be much quicker: Daimler and Bosch wanted to develop the self-propelled car for urban traffic by the beginning of the coming decade, i.e. in about five years.

Together, the Stuttgart-based car mechanic and the world’s largest supplier want to develop software and algorithms for an autonomous driving system that makes the fully automated (SAE-Level 4) and driverless (SAE-Level 5) driving possible. The vehicles should help, among other things, to improve traffic flow in cities and increase safety on the roads, Daimler shares.

The vehicles should help, among other things, to improve traffic flow in cities and increase safety on the roads, Daimler shares.

Behind the cooperation with Boch is the idea of a robot taxis. In certain city areas, users should be able to order self-employed car-sharing cars via a smartphone app, which brings them to the goal, while they can devote themselves to other things.

The vehicle comes to the driver, not the driver to the vehicle,” Daimler summarizes. Corresponding business models are to be implemented until 2025.

It was only recently that Bosch presented its self-learning auto computer for autonomous vehicles. Over the next four years, the company plans to invest 300 million euros in AI research. The core of the so-called “brain for self-propelled cars” is a chipset from Nvidia. The graphics card manufacturer is currently positioning itself as a partner to the auto industry.

It includes regulations for fully automated driving, but not for the autonomous operation of cars, which may start off completely without a steering wheel or the attention of the occupants.

In Chile, Solar Power Plants Are to Supply Electricity Around the Clock

The significant disadvantage of solar systems is their dependence on daylight. In Chile, solar power plants are to be built, which still provide electricity at night or in bad weather.

In addition to wind and hydropower, solar energy is the great hope for climate-friendly electricity production. Particularly in warm regions with high solar radiation the potential is enormous.

However, a crucial weak point in the sun-dependent electricity production has been the fact that less or no electricity can be produced at night and in bad weather. The exclusive supply of a region with solar power is therefore difficult.

The US company SolarReserve has now solved this problem: In Chile, three solar thermal power plants are to be built wh

The significant disadvantage of solar systems is their dependence on daylight. In Chile, solar power plants are to be built, which still provide electricity at night or in bad weather.

In addition to wind and hydropower, solar energy is the great hope for climate-friendly electricity production. Particularly in warm regions with high solar radiation the potential is enormous.

However, a crucial weak point in the sun-dependent electricity production has been the fact that less or no electricity can be produced at night and in bad weather. The exclusive supply of a region with solar power is therefore difficult.

The US company SolarReserve has now solved this problem: In Chile, three solar thermal power plants are to be built which can supply electricity 24 hours a day and seven days a week.

This makes possible a storage solution in the form of a liquid salt solution. It should circulate during the day and heat up. At night, it is stored in tanks at a temperature of 566 degrees Celsius.

In the case of energy supplies, the hot salt water is heated. The resulting steam drives a turbine, which in turn produces electricity. Up to 5.8-gigawatt hours can be stored for 13 hours. The largest of the three planned plants in the Chilean province of Tamarugal is to be able to deliver 450 megawatts around the clock.

The installations consist of up to three solar towers, surrounded by several thousand mirrors, which bundle the sunlight and return to the towers. In this way, the salt solution circulating therein is heated. A similar facility is under the name Ashalim Project is just in the Israeli desert. The 250-meter high Solturm tower is the highest of its kind.

The Chilean government has recently given the green light to the construction of two of the three facilities. The construction work for the Tamarugal power station and another in Copiapó can theoretically start according to the SolarReserve, but an approval for the third facility in Antofagasta is still pending. Until the new solar power plants actually deliver energy, however, it could still take quite a while.

First, SolarReserve needs to find customers for solar power. Contracts with potential buyers are to be signed at a public auction in October. It is then necessary to attract investors for the construction of the facilities.

The implementation of the Solar Power Plants in Tamarugal alone will cost 2.6 billion dollars. If all negotiations are proceeding as planned, construction work is scheduled to start at the end of 2018.

The principle used by SolarReserve is not new. In Arizona and Las Vegas, similar plants are used, which also store energy in the form of heated salt. However, both power plants use an additional transfer liquid in the form of oil to heat the salt.

SolarReserve is the first company to heat the salt directly. The company has already implemented and commissioned a first small plant in Nevada with promising results.

The power plant produces more electricity than expected; the yield is 105 percent of the contractually secured electricity. Other comparable facilities are lagging behind their set goals.

The goal for projects in Chile is to be able to compete directly with coal and nuclear power plants. The plants should work for 30 years without having to resort to fossil fuels or to have to exchange the liquid salt.

SolarReserve can also be used as a fertilizer. The company wants to restore the environment with its power plants as little as possible. To do this, work with local communities is carrying out extensive studies before construction. The selection of the sites and the use of water-saving technology are also taken into account during planning.

The introduction of 24-hour solar power plants could be a major step in the spread of renewable energies. In any case, it is another sign of global efforts to make electricity production climate friendly.

Europe is also on a right path in this regard. In the North Sea, for example, an artificial island for electricity generation by wind power is to be created, which would supply electricity to several surrounding countries.

The World’s First Hydrogen Train is Being Tested in Germany

The world’s first hydrogen train is currently being tested in Salzgitter, the Coradia iLint. 2018 the first journeys with passengers are to follow.

The world’s first hydrogen train has completed its maiden voyage on a test track in Salzgitter. The CO2-free Coradia iLint was developed by the French rail vehicle manufacturer Alstom and reaches speeds of 80 to 140 km/h.

The ride was the first of a four-week trial to test the stability of the power supply system and the electrical braking system. The year 2018 will be the first tests with passengers in Germany.

According to Alstom, the Coradia iLint is the first low-floor passenger train powered by hydrogen-oxygen fuel cells. Oxygen atoms react with hydrogen atoms and generate electrical energy. Even cars like the Toyota Mirai use the technology, but they ha

The world’s first hydrogen train has completed its maiden voyage on a test track in Salzgitter. The CO2-free Coradia iLint was developed by the French rail vehicle manufacturer Alstom and reaches speeds of 80 to 140 km/h.

The ride was the first of a four-week trial to test the stability of the power supply system and the electrical braking system. The year 2018 will be the first tests with passengers in Germany.

According to Alstom, the Coradia iLint is the first low-floor passenger train powered by hydrogen-oxygen fuel cells. Oxygen atoms react with hydrogen atoms and generate electrical energy. Even cars like the Toyota Mirai use the technology, but they have not yet established themselves on the market.

According to the US Energy Information Administration, this type of energy generation is “two to three times more efficient than an internal combustion engine” with petrol. In addition, the hydrogen drive does not emit any pollutants but only water vapor and condensation water.

On the test track in Salzgitter, there is an own hydrogen filling station where the gas is pumped into the pressure tank of the Coradia iLint. The hydrogen used in this process is actually a by-product of an industrial process and is used as a waste product in a meaningful way. Thus the Coradia iLint is an excellent alternative to the diesel train.

On a second test track in the Czech Republic, the train is accelerated to its maximum speed of 140 km/h. Previously, all electrical and pneumatic functions were checked and confirmed at a standstill.

This test drive is an important milestone for environmental protection and technical innovation. Today, this new drive system, which has so far been tested successfully on the trial bench, is a decisive step for clean mobility in Europe.

If all tests are successful, next year the train will start its trial with passengers on the route Buxtehude-Bremervörde-Bremerhaven-Cuxhaven. In 2021, the Coradia iLint is also to be used in Great Britain.

However, the mammoth task has to be tackled first, to ensure a nationwide hydrogen supply. So far, there are only eight hydrogen filling stations for cars all over the UK.

In Germany, there were already 21 stations in mid-2016, until 2023 the number will be increased to 400 increase. The British government also wants all cars to be driven without emissions by 2050, with the aim of expanding hydrogen filling stations in particular.
