Scientists develop new material for improving efficiency of solar panels

Clean energy acts as an intersection which acts as a suitable substitution for fossil fuels. It is noticed that solar power plants have to boost their planning in a better way to compete with the electrical output of the non-renewable energy sources. The design highly depends upon the renovation and growth of newly made products such that they ingest and interchange the heat at the higher temperatures.

 The solar panels which are found on the hybrid cars or the residential rooftops are found lesser compared to the ones found in the solar power plants. Since the solar panels found in the power plants are huge and countless in number so the heat they absorb is more so they absorb more thermal energy from the sun as much as they can and then they create a passage so that the heat can pass through and that heat is converted into fluid-filled converter is known as heat exchanger.

A liquid version of carbon dioxide which is known as supercritical CO2 acts as an agency in converting the energy and the hotter the fluid gets the more the electricity can be produced. Researchers from the University of Toledo have discovered a newer technology based on the supercritical CO2 as a channel which helps in converting into energy and here this fluid minimizes the manufacturing costs and also minimizes the electricity level and commits to working in a good manner with accuracy and it can benefit to the future power plants too. This report was published in Nature journal

An assistant professor in the mechanical engineering department at Texas A&M University Dorrin Jarrahbashi said that the metal material which is used to make the solar panel heat exchangers using supercritical CO2 energy cycles are only firm up to 550 degrees Celsius and he also added that if the heat rises then break down occurs which leads to the replacement of the components and becomes less effective.

To solve this problem the researchers developed a new complex material which had a combination of ceramic and tungsten which is refractory metal which can take the heat of over 750 degrees Celsius. The tendency to tolerate heat can lead to more effectiveness in generating electricity in united solar and supercritical CO2 power plants by 20%. Compared to the fossil fuels the output and the longevity of the mixture and the lower cost in production will help in cutting down the price of construction and maintenance of powerplants.

It is said that with the help of the unique chemical, mechanical and thermal properties there is numerous approach for the compound. It started from improving its nuclear power plants to building rocket nozzles the results of this revolution has made a vast impact in the future of research and industry.

Carbon dioxide levels reach an all-time high of 415ppm

According to the sensors at the Mauna Loa Observatory which is research outpost of the National Oceanic and Atmospheric Agency, carbon dioxide levels have crossed 415 parts per million and is reaching 415.26 parts per million. This kind of drastic change has been recorded for the first time in human history.

On 13th May 2019, a climate reporter Eric Holthaus posted about the macabre milestone which he came to know from the data which was recorded and presented by the Scripps Institution of Oceanography at the University of California. He tweeted that this was the first time our planet’s atmosphere has more than 415 ppm CO2 and he also added that he don’t know about a planet like this.

A few years ago it was seen that carbon pollution was about 400ppm which drastically changed to 410ppm in the year of 2017. Scientists already knew that the rate of change of carbon poising was uncontrollable and it would hit around 415ppm in the year 2019.

The Keeling Curve was recorded to be wrong which was published on the Scripps website and the false data was changed after many sites complained about the wrong data and reported it to the grim accomplishment. Scripps wrong data suggested that CO2 levels crossed 415ppm on May 3rd itself. But finally, we have reached that 415ppm mark. 

The director of the Scripps for performing the CO2 program Ralph Keeling said that the average growth rate remained on the high end and also added that the increase should be around three parts per million from the last year but according to the recent average study it has been recorded to be 2.5 ppm and he also added that they are observing the effects of mild El Nino conditions over the use of fossil fuels.

It is observed that the use of fossil fuels is a real problem here. In the year of 1910, the atmospheric CO2 stood at 300ppm -higher than that of 800,000 years before. Now, in just a century it jumped 100+ppm and this drastic change in the rate took place because of the pollution and the cross of 400ppm was a hugely symbolic moment numerically at least, but the symbolism doesn’t end there.

It is to be noted that a huge amount of heat will be trapped on earth if this carbon pollution keeps getting thicker in our atmosphere we can experience global warming in a very different way which didn’t happen in last hundred million years.

I think we all should help reducing carbon dioxide levels by doing some means. Are you doing something to reduce carbon dioxide levels? Tell us with a short and quick comment
