Global warming is a serious problem for the mother earth. When everyone talks about temporary solutions, we are here to discuss a recent invention that can sustainably reduce global warming.
When we recommend driving less, changing lights, or using daylight, we are actually compromising some of our hobbies, attractions, and habit.
Since these are great ways to reduce global warming, we should continue practicing these. Having said that, we have found a great invention that can significantly and sustainably reduce global warming.
A reflective drywall panel that can send the radiant heat back to its source, is the invention that we are talking about. Using this panel will require less energy to make our rooms comfortable resulted in less energy consumption, eventually getting less fossil fuel burned. As the patent started saying that-
“The warnings from many scientists about the effects of global warming caused by the greenhouse effect, and the rising costs of fossil fuels and electric power production, encourage the reduction of energy use in homes and offices. It has been estimated that radiant heat flow accounts for up to seventy percent of the heat loss or gain through the outer walls and ceilings of building structures. This phenomenon increases the need to burn fuels for heating or to utilize electrical energy for cooling. A wall or ceiling panel that would effectively diminish radiant heat loss or gain would thus lead to a reduction in the use of fossil fuels and/or electric energy. In addition to the monetary savings involved, the lowered production of carbon dioxide gases would greatly abate the cause of the greenhouse effect.”
So, this simplistic drywall panel model will solve a never ending cycle of greenhouse effect by reducing the use of fossil fuels to cool down our houses. See the graph for better view of the cycle-
The cycle we have used for illustration is a vicious cycle that continuously increases the greenhouse effect.
When we feel the heat, we use cooling machines like the air conditioner, this results in burning fossil fuels and finally, the greenhouse effect. As one cycle is ended, the warming is increased and we require more energy to make our home comfortable resulted in more fossil fuel burning. And this again increases the warming and we require even more power to cool down the room, resulting in more power consumption and finally, more fossil fuel.
This process makes global warming faster everyday by increasing the demand for electricity. For restricting global warming into a controllable level, we need a way out to interfere in this cycle.
Therefore, to reduce the greenhouse effect sustainably, we need a solution for making the home comfortable without burning fossil fuels. The reflective drywall panel is invented for interrupting the cycle we have discussed above.
This will reflect the radiant heat backward allowing the other side of the drywall remains more comfortable to live in. So, you will need less electricity to run the air conditioner that will result in a significant drop in demand for electricity. And will eventually reduce fossil fuel usage worldwide.
So, we should now look at the invention. The abstract of the patent reads as follows-
“Abstract: The reflective drywall panel (10) to reduce radiant heat transfer is a drywall panel (12) constructed with a reflective surface (14) on one side thereof. The reflective surface (14) functions to reflect radiant heatwaves into a space during heating season or away from the space during cooling season. The reflective surface (14) is fabricated from a plastic-metal sheet having a shiny surface. The sheet (14) is attached to the back side (stud side) of a drywall or ceiling panel (12).”
As you can see that the production of this material will be very simple comparing to other green materials we use in our daily life. This only needs a “metallicized plastic sheet having a shiny surface” attached to the drywall with conventional adhesives.
Therefore, this can become a very cost-effective way to make the earth more comfortable to live in.
What Outcome We Will Get from This?
Now, we should look at the outcome we will get if we can use this invention in building houses.
By conducting a survey asking people about their average air conditioner usage per day, we have found that a person uses air conditioner almost 7-8 months in a year for 7-8 hours on average daily. (Assuming 4 hours/day roughly on average for a year.)
If we calculate an estimated electricity usage of a person for making the room comfortable, that comes out at a cost of around 1.5 MWh of electricity per year.
Roughly, a kWh of electricity is generated by burning around 1 pound of coal or 0.1 gallons of petroleum. That results in-
150 gallons of petroleum or 0.75 ton of coal consumption by a single person in a year only by using a 1000 watt air conditioner.
If we can reduce the air conditioner usage by 50% by using the reflective drywall panels, we will be saving 75 gallons of petroleum or 0.38 ton of coal per year.
Assuming that the reflective layer will remain working for 20 years, that will save 1500 gallons of petroleum or 7.5 tons of coal from burning and emitting greenhouse gas in the environment. And, this is the data for a person only.
Can you think of how much we will be saving if we start replacing our conventional drywalls with reflective drywall panel?
