Should We Install Solar Panels in Our Roof? - Part 2 - Science 38




Image 1- Solar panels on the roof.

Much research showed that housing value could increase by up to 20 times if we have a 5 kW solar system on our roof.

In term of dollar, solar panels could make housing value up to US$ 24,000 in the market. Quite good for investment.

It is estimated that 20 solar panels need roof space of 5 hundreds square feet, then, it would produce 5,000 watts.

However, in Louisiana, let’s say we pay US$ 150 per month for electric bill, we might need solar panels system to produce 9500 watts.

Interestingly, the solar system may last for 25 years. We avoid rising cost of electricity for so long, hence, save thousands of dollars.

Should we install solar panels in our roof?

Useful of Weeds and Wild Flowers in the yards – Part 2 - Science 36

You may read the previous post (Part 1):

- The Rainbow Before Evening : Useful of Weeds and Wild Flowers in the yards – Part 1 - Science 36

The weather in the last Summer was uncertain: too hot and then flood from heavy rain.

Flowers and my four month avocado tree dried out, I couldn't save it and the fig tree is dying.

Some fruits I have never picked up due to some squirrels and wild birds love to eat them.

Back to my yards, I have planned to clean and clear it form weeds and wild flowers.

But I think back about sustainable environment as Christine mentioned in her posting (Please see at: Important for pollinators).

Should We Install Solar Panels in Our Roof? - Part 1 - Science 38

Renewable resources for energy such as wind and sun are getting popular in our state, and might be in many states in the USA right now.



Image 1- Solar panels, sold at Home Depot

There are plenty reasons why people eager to use these resources, one of them is stable prices.

In case of solar energy, our neighbors consider several benefits to install solar panels on their rooftops are:

- federal incentive of tax credit
- additional the tax credit incentive is provided by some states.
- increase housing value
- and saving electricity cost for years



Image 2- Roses, just for illustration

Louisiana state does not give additional tax credit, but provide property tax exemption. Let’s say, we as Louisiana residents will get:

- 30% tax credit from federal government of solar panels cost.
- excluded added value of property tax.

Do you Love Tomatoes? - Science 37

If you love tomatoes, there is good news for you. It is because science proves that tomatoes have several benefits.



Image 1- Tomatoes in the bowl

Just to let you know, as reported by Marina Savchenko (2021: What Is the Most Popular Fruit in the World? Top 5 Fruits Ranked) that tomato is the most popular fruit in the world. Other 4 most popular fruit are:

- apples
- bananas
- oranges and mangoes.

Moreover, based on several scientific journals that tomatoes have at least 4 benefits. What are they?



Image 2- Sliced of tomatoes.

The 4 four benefits are:

1. Contain more Potassium (American Journal of the College of Cardiology).
2. Reducing risks of sun damaged skin (Scientific Report)
3. Our body observes iron effectively (Center for Biotechnology)
4. Our wound will be heal faster (International Journal of Surgery)

Do you like to consume tomatoes?

Useful of Weeds and Wild Flowers in the yards – Part 1 - Science 36

We are in the second week of April. The weather is getting warmer up, may reach up to 86 F (30 C) in our city, Baton Rouge, LA.



Image 1- Beautiful wild white flowers, eagerly to keep their existence.

It's a good time to work my yard that I left about over a month. Shrubs are growing in some spots and they are surrounding the house.

Normally, in early Spring whenever many kinds of plants spur up with lovely manner show their buds, we just let them growing and flowering.

My reasons are not only to enjoy the amazing views but also to keep small wild flower as the first flower to invite the bold bees and insects to do pollination to my fruit trees.



Image 2- Wild flower, Waiting for “helper” for sustainable.

So, I don't need to catch them or borrow from somewhere. Then, in the Summer, I (my planning) to avoid all weeds and wild flowers by clearing them all.

Then, what happen?

Can We Find Broccoli in the Wild? - Science 35

As reported by Cision PR Newswire (2022: Green Giant® Survey Reveals Broccoli As America's Favorite Vegetable in 2022) that 29 states chose broccoli as the favorite vegetable.



Image 1- A cooked Broccoli, healthy food

Then followed by “corn, carrots, potatoes and asparagus consecutively. The question: “Can We Find Broccoli in the Wild?” The answer is no. Why?

It is because human have developed this vegetable with breeding process through many years.

Human found the wild cabbage with scientific name Brassica oleracea. Unfortunately this cabbage produces:

- small flower buds every two years
- has no good taste and flavor.



Image 2- A bunch of Broccoli, sold in Walmart

Farmers manipulated environment to make wild cabbage reproduce several times in a year.



Image 3- The carnivore plant, illustration only

Luckily, farmers able to select the offspring based on their:

- big flower buds
- have very good taste and flavor.
- faster grow



Image 4- Broccoli as vegetable.

The plant is reproducing, and known as broccoli nowadays. Do you like broccoli tast and flavor?

Alligator Plants Grow Well in Louisiana – Science 34

There are several names for a plant with bell shape flowers, one of them is Alligator Plants, and the plant recent scientific name is Kalanchoe daigremontiana.



Image 1- Blooming of Alligator Plant flowers.

The plant is native to the island of Madagascar, Africa. Then it separates to other tropical regions.

Alligator Plants have been transported to America, moreover, the plants have adapted easily to several states.

We may find the plants in the states such as:

- Florida
- Hawaii
- Louisiana and other warmer states.



Image 2- Two alligator plants at the yard

Even thought some of our neighbors said that the plant is rare, but we have seen Alligator Plants are sold in some markets.

We bought it from a nearby farmer market with reasonable price about a couple years ago.

I think this bell shape flowers plant is easy to grow and maintain. Like other succulents, the plants no need much water, and may live for years.

Have you seen the Alligator plants?

Could Parasite Control Human Mind? - Science 33

There are many reports about infection of a parasite to animals and humans in some parts of the world recently.



Image 1- The cat, host of parasite

The parasite is a single cell protozoan with scientific name Toxoplasma gondii. Actually, the parasite is common worldwide, and causes disease called as toxoplasmosis.

What interesting, especially for me that this parasite could alter behaviors of infected living things.

In fact, as reported by Zeleb.es (2023: A mind- controlling parasite that affects hyenas - and humans too) that 33% of human population is infected by this parasite.



Image 2- Just for illustration

Then, we wonder: Could parasite, Toxoplasma gondii controls human’s mind?

The plain answer is not really. Highly possible that the infected animals and humans might eager to take risk than the normal ones.



Image 3- Community activities, illustration

As suggested by Zeleb.es (2023) that risk takers tend to success as entrepreneurs.

Do you believe it? What do you think?

Is Mockingbird a Smart Bird? - Science 32

We have talked at previous post about mockingbirds as permanent residents of our state: Mockingbirds are Permanent Residents of Our State – Nature 47



Image 1- A mockingbird on the branches

Actually, the pictures were taken after several days approaching the bird.

At the first, I saw a bird sitting on the branch of a tree at my office. When approaching, the bird flew away.

Second days, I move closer, but have no chance to take a picture. Then, obscure pictures are taken after third days.

I believe that the mockingbird “learning” day by day to recognize me. Then, Is Mockingbird a Smart Bird?



Image 2- Freezing temperature, illustration only

Yes, mockingbird is a smart bird as suggested by David Mizejewski (2023: Brainy Birds: America’s Smartest Bird Species).

It is true in my case, the mockingbird let me to take its picture with my cellphone in “safe distance” after several days.



Image 3- A mockingbird, the smart bird

Finally, It is said that mockingbirds able to mimic other bird songs such as hawks, jays and blackbirds
