Saudi students invent robot to improve solar panel efficiency

  • The device boosts productivity from 70% to 80%

TAIF: Two students at Taif University in Saudi Arabia have invented a robot that improves the efficiency of solar panels by more than 14 percent by keeping them clean and dust free.
The technology developed by Ahmed Fayez Ahmed Mohammed and Ahmed Ali Zayed Oudha, who are studying electrical engineering, addresses the problem of decreased efficiency in the production of electricity by photovoltaic solar panels caused by harsh environmental conditions, including the build up of dust, which can be particularly problematic in desert environments.
To counter this, they created a high-performance, cost-efficient smart robot that prevents the accumulation of dirt and dust on the panels.
It has sensors that allow it to move across the surface of the panels and accurately detect and remove any buildup. They also prevent the robot from wasting energy operating when the panels are not generating power — for example at night or on cloudy days. The cleaning mechanism uses cylindrical brushes and a high-performance fan.
The students worked on the project under the supervision of Dr. Mohammed Salahuddin Mohammed Suleiman and Dr. Musleh Al-Harthy, the dean of the engineering faculty.

Fraud alert over cryptocurrency falsely linked to Saudi Arabia

  • The website of a cryptocurrency company is promoting what it calls the CryptoRiyal and SmartRiyal
  • The Singapore-based company uses the Saudi emblem of two crossed swords and a palm tree

JEDDAH: Fraudsters are trying to lure victims into investing in a “virtual currency” with false claims that it is linked to the Saudi riyal and will be used to finance key projects, the Saudi Ministry of Finance warned on Tuesday.

The website of a cryptocurrency company in Singapore is promoting what it calls the CryptoRiyal and SmartRiyal, using the Saudi emblem of two crossed swords and a palm tree. Its “ultimate goal” is to finance NEOM, the smart city and tourist destination being built in the north of the Kingdom, the company claims.

“Any use of the KSA name, national currency or national emblem by any entity for virtual or digital currencies marketing will be subject to legal action by the competent authorities in the Kingdom,” the ministry said on Tuesday.

The fraudsters were exploiting ignorance of how virtual currencies work, cryptocurrency expert Dr. Assad Rizq told Arab News.

“A lot of tricks can be played,” he said. “Some of these companies are not regulated, they have no assets, and even their prospectus is sometimes copied from other projects.

“They hype and pump their project so the price goes up. Inexpert investors, afraid of missing out, jump in, which spikes the price even higher. Then the owners sell up and make tons of money.

“Cryptocurrencies are a risky investment for two reasons. First, the sector is not yet fully regulated and a lot of projects use fake names and identities, such as countries’ names or flags, to manipulate investors.

“Second, you have to do your homework, learn about the technology. And if you still want to invest, consider your country’s rules and regulations.”
