There Really Is Something Ironic About This

Posted on by

Lately those opposed to constructing wind farms off of our coast have cited the number of dead whales that have washed up on our shores since we started exploring on our shores and building platforms for those wind farms. There is also a move (which I admit I was unaware of) to construct floating solar farms. Aside from any other considerations, how much toxic liquid would a broken solar panel release into the ocean? I have no idea–I am simply asking the question.

On Thursday, Watts Up With That posted the following headline:

The World’s Largest Floating Solar Farm Wrecked by a Storm Just Before Launch

That can’t be good.

The article reports:

h/t Dr. Willie Soon; Who could have predicted acres of fragile floating structures would be vulnerable to bad weather?

Madhya Pradesh: Summer Storm Damages World’s Largest Floating Solar Plant at Omkareshwar Dam (Watch Video)

Indore: A summer storm on Tuesday damaged a floating solar plant at Madhya Pradesh’s Omkareshwar dam. The floating solar plant, situated in the backwater of the dam, is the biggest of its kind in the world. A joint venture between  Madhya Pradesh Govt and National Hydroelectric Power Corporation (NHPC), the project was nearly completed and ready for its launch. A part of the project became operational last week.

The project near the village of Kelwa Khurd, aimed at generating 100 MW of electricity, with additional capacities of 88MW at Indawadi and 90 MW at Ekhand village. However, on Tuesday, summer storms with the speed of 50kmph hit the project and threw the solar panels all around the place. No employee was fortunately injured.

The article concludes:

Plastics tend to disintegrate under tropical sunlight, especially when in contact with water or water spray. Ultraviolet from the sun drives exotic chemical reactions, which leads to chemical breakdown.

Metal sitting in water is difficult to manage, even stainless steel is not immune to corrosion. All metal structures in contact with water need to be protected with sacrificial anodes or comparable protective measures. Electricity and metal are an especially bad combination, any electrical fault which causes a current to run through metal in contact with water can cause corrosion to occur thousands of times faster than normal.

Let us hope developers and politicians take the hint, and stop throwing our money at inherently flawed ideas like floating solar arrays.

Sometimes things that look really good on paper just don’t work.

 

What A Great Idea!

Yesterday One America News posted an article about the use of robots to sanitize places and things to stop the spread of the virus.

The article reports:

A company from Argentina is using robots in the fight against the coronavirus. UVD Robotics has been testing a new product that can sanitize both spaces and objects with ultraviolet light.

On Friday, developers tested the robot on a bus, where it was able to clean seats, walls and floor using just UV light.

According to the World Health Organization, cleaning products with chemicals such as bleach or hydrogen peroxide traditionally are only 60 percent effective against germs. UV light reportedly eliminates bacteria 99 percent of the time.

“Ultraviolet light is a light that the sun emits naturally,” explained CEO Martin Gonzalez. “In this case, we use type ‘C,’ which is very high energy and works by destroying the DNA of bacteria, the RNA in the case of viruses, thus avoiding propagation or spread.”

He added the robot can also be used to protect health care workers, who are being exposed to bacteria in hospital rooms.

What a great idea! You don’t have to clean up chemicals, you don’t have to worry about inhaling fumes, and almost all of the germs are killed.

Messing Up The Environment In Your Home To Save The Environment Outside Your Home

The American Congress has done it again. In an effort to save the environment, they have put American households at risk. Hot Air posted an article yesterday stating that a study done at Long Island‘s Stony Brook has shown that compact fluorescent lights (CFLs) emit high levels of ultra violet radiation. The report states that the bulbs emit rays so strong that they can actually burn skin and skin cells.

The article at Hot Air reports:

“The results were that you could actually initiate cell death,” said Marcia Simon, a Professor of Dermatology.

Exposure to the bulbs could lead to premature aging and skin cancer, according to doctors.

“It can also cause skin cancer in the deadliest form, and that’s melanoma,” said Dr. Rebecca Tung.

The article points out that in every bulb the researchers tested they found that the protective coating around the light creating ‘phosphor’ was cracked, allowing dangerous ultraviolet rays to escape. This sounds like a quality control problem in the manufacturing process as much as anything else.

The radiation problem is in addition to the danger caused by actually breaking a bulb in your home.

The article reminds us:

Actually, they’re not all that eco-friendly, as even the government acknowledges.  The EPA wants to argue that the release of mercury from CFLs in disposal is less than that released from the burning of the amount of coal one saves by using them.  That may well be true overall, but not if one breaks in your house.  At that point, you need to conduct an hours-long cleanup — and even if you want to dispose of an unbroken CFL, it takes special disposal in most jurisdictions due to the eco-unfriendly nature of CFLs.

I am beginning to appreciate the genius of Thomas Edison.
