Max Laughlin and his controversial theory: CERN sent us to a parallel universe?

Posted by in categories: cosmology, solar power, sustainability

The young man has made several statements that compromise the scientific community, but the most shocking is related to CERN and how it could have destroyed our universe.

Regarded as a genius child and listed as the “most intelligent young man in the world”, Max Laughlin surprised the world with his great intellectual abilities.

With only 13 years old he could develop from scratch its own device for energy access. A system that is capable of providing all the necessary energy without the need for oil, coal or solar energy.

Scientists Achieve Record Energy Efficiency for Thin Solar Panels

Posted by in categories: chemistry, solar power, sustainability

Scientists from the University of Surrey and Imperial College London have achieved an increase in energy absorption in ultra-thin solar panels by 25%, a record for panels of this size.

The team, which collaborated with AMOLF in Amsterdam, used solar panels just one micrometer thick with a disordered honeycomb layer on top of the silicon panel. The biophilic design draws inspiration from butterfly wings and bird eyes to absorb sunlight from every possible angle, making the panels more efficient.

The research led to a 25% increase in levels of energy absorption by the panels, making these solar panels more efficient than other one-micrometer-thick panels. They published their findings in the American Chemical Society’s journal, Photonics.

How to clean solar panels without water

Posted by in categories: solar power, sustainability

Dust that accumulates on solar panels is a major problem, but washing the panels uses huge amounts of water. MIT engineers have now developed a waterless cleaning method to remove dust on solar installations in water-limited regions, improving overall efficiency.

Researchers develop PERC solar cells with 100% recycled silicon

Posted by in categories: climatology, economics, solar power, sustainability

The installations of photovoltaic (PV) solar modules are growing extremely fast. As a result of the increase, the volume of discarded solar modules that end up on the recycling market annually will grow at the same rate in the near future. Currently, the aluminum, glass, and copper of the discarded modules are reprocessed; however, the silicon solar cells are not.

Now, researchers from the Fraunhofer Center for Silicon Photovoltaics CSP and the Fraunhofer Institute for Solar Energy Systems ISE, together with the largest German recycling company for PV modules, Reiling GmbH & Co. KG, have built new PERC solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels.

The team has developed a process for recovering the silicon material with funding from the German Federal Ministry for Economic Affairs and Climate BMWK. The technique is claimed to recycle silicon from different types of crystalline silicon PV modules, regardless of manufacturer and origin.

Solar power reaches 1 TW milestone

Posted by in categories: business, finance, solar power, sustainability, transportation

Like electric vehicles – traditionally seen as expensive and niche – solar power is now becoming a realistic option for many households, as well as businesses wishing to decarbonise their operations. While the upfront costs of installing a photovoltaic (PV) rooftop system can be expensive, home solar will usually pay for itself within 5–10 years – and then provides the owner with an essentially free, limitless supply of clean energy, decentralised and unaffected by price volatility. Unlike the world’s increasingly scarce, finite supplies of coal, oil and gas, our Sun will continue to shine for another five billion years. Home solar can also be combined with batteries (which, like solar, are rapidly declining in cost) for energy storage at night.

At the utility scale, gigantic solar projects are now emerging in many countries. Recent years have seen the first gigawatt-scale (GW) facilities. The largest has a nameplate capacity of 2.3 GW. China is the world leader, accounting for 30% of all solar electric generation, followed by Europe (21%) and then the USA (16%). The vast majority is produced from PV modules, with a small fraction obtained by concentrated solar power (using mirrors or lenses to concentrate a large area of sunlight onto a receiver).

Sonoma County Airport Launches Solar Power Systems

Posted by in categories: climatology, government, solar power, sustainability

The Charles M. Schulz Sonoma County Airport had two solar power systems installed onsite and made them live in February. Over the course of their electricity-generating life spans, they will offset thousands of tons of CO2 emissions and potentially save millions of dollars.

Sonoma County has been hit particularly hard by wildfires in the last several years. These natural disasters occur with some regularity on their own, but many believe the latest ones are connected to the effects of climate change. The county has been experiencing higher temperatures and droughts as well. As a result of these challenges, Sonoma County’s government set a goal for the county to be carbon neutral by 2030. The airport solar power installations fit within the carbon-free plan. (The California state government has a goal for California to be operating on clean, carbon-free electricity by 2045.)

Jon Stout, the Sonoma Airport Manager, and Rachel McLaughlin, ForeFront Power’s Vice President of Sales & Marketing, provided some insights to CleanTechnica about the new solar power systems. (The last three answers are from ForeFront.)

Scientists figured out a way to clean dust off of solar panels without using water

Posted by in categories: solar power, sustainability

Dust on solar panels reduces their output significantly, so they need to be kept clean. But how? Scientists say they have a solution.
