The most advanced solar plant in the world suffers setbacks

The leading national laboratory of renewable energy of the USA (NREL) has published a report that this is very contradictory reviews of installations at the expense of concentrated solar power (or CSP technology – concentrated solar power).

We are talking about the Solar Two project, within which was built the solar power plant at Crescent Dunes. This unique structure, consisting of 10347 mirrors-heliostats mounted on the area of 647.5 hectares around 195-foot tower.

Mirror can change its position, concentrating the solar rays on the container with special salt solution in the upper part of the tower. As a result, the salt is heated to 575 °C, and the resulting heat can be stored for a long time (10 hours), and used to generate steam required to operate the generators.

However, in the process, CSP-installation, a number of serious problems. One of them is the death of a large number of birds accidentally fall into the range of the heliostats where they literally turn to ash.

Another, more serious problem is the leakage of the salt reservoir discovered in 2016 and is associated with errors in engineering calculations. Although much of the damage arose, the plant had to stop for eight months to determine the causes.

Summarized and performance. Instead of the planned 52% of the solar power plant showed an average power factor of only 20.3 percent.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
