Scientists are looking for ways that we can effectively use the light and heat from the sun. One idea that has caught their imagination is solar roads. They are expected to produce clean and renewable energy.

With solar panels on the surfaces, solar roads cost more than traditional roads. However, besides the functions of traditional roods, they have the panels to receive sunlight and change it into the energy to supply power to homes, factories and street lighting. There are four layers in a solar panel:

•Base layer: It is made of insulation material and forms a good grip with the road below this layer.

•Middle layer: This is the most important layer. It holds all kinds of power lines connecting all the solar parts in the panel, like LED lights and the heating system.

•Top layer: This layer is super-strong glass. It allows the panel to hold the weight of the heaviest vehicles.

•Capping: This is the topmost layer used to offer extra protection to the solar parts in the panel. The layer must be rough enough to provide the traction for the safety of vehicles.

With the smart design, solar roads can successfully charge the vehicles on them. And the roads have inbuilt LED lights to replace the traditional rood signs and lines, which are usually painted and harmful to humans. What’s more, the heating systems in the solar roads can take care of the snow and ice on the roads for drivers.

Test solar roads have been built in several countries (France, China, USA, etc.) since 2014. The first word solar road project, Metrics of Watt Way in France, was set up by a French company called Construction Colas. It was an example of low effectiveness. In the first year, it had been expected to produce around 767 kWh of energy a day, but it only produced 409 kWh. Even so, the production could increase with design improvements. Of course, more time is needed before this technology is put into use.

Solar roads may not be widely used in the near future, but they are indeed great for an environment-friendly and energy-saving world.

“Motasharefon bema’ refatek!” is often heard in Arabs’ daily talks. This greeting in the language Arabic means “Nice to meet you!” You may find Arabic difficult to understand, but the following facts can offer you some basics.

Arabic is s language of over twenty countries across the Middle East and North Africa, It’s also one of the six official languages of the UN. Now about 400 million people worldwide speak Arabic.

Life in Outer Space

Chinese taikonauts Zhai Zhigang, Wang Yaping and Ye Guangfu carried out the Shenzhou-13 spaceflight mission （任务） that started on Oct. 15, 2021. This mission lasts 6 months, which was also a national record. Zhai is the commander （指令长） who performed China’s first spacewalk in the Shenzhou-7 mission in 2008. Wang, who was in the Shenzhou-10 mission in 2013, is the first Chinese woman astronaut to visit China’s space station. Ye is a new comer to space.

The trio had carried out two spacewalks and completed more than 20 scientific tasks. Besides their tasks, they had also given two live lectures from the space station, showing the students their living and working areas at the Tianhe core module and several scientific experiments under zero-gravity conditions and answering real-time questions from students.

The trio also became the first Chinese to spend the nation’s most important festival — the Chinese Lunar New Year — in outer space.

They returned to Earth on April 16, 2022 and made Shenzhou-13 mission a great success.
