Fun Fact of the Day:

Carbon Dioxide (CO₂) has a polar covalent bond. This means it doesn't share its electrons equally between atoms. So when it is floating in free space..... it wiggles!!

Look at it go!

This type of wiggling allows CO₂ to collect light energy (heat) that O₂ and N₂ cannot absorb! This is how it is classified as a greenhouse gas!

(Extra Fun Fact: Water has similar properties and is also considered a green house gas!)

hi this is your local car enthusiast reminding you that if you want to drive in a sustainable way, the best thing you can do is maintain your current vehicle for as long as physically possible, and if it dies on you, buy a used car with decent-to-good gas mileage. if possible, learn manual.

EVs are usually powered with lithium ion batteries, which is of debatable environmental friendliness and rife with human rights abuses. needless to mention that the US already produces an insane amount of waste and people buying new, expensive EVs en masse will make this issue even worse. simply put, in the vast majority of cases, you, as an individual, will produce less waste and pollution by keeping your current vehicle as opposed to buying a new EV. EV sales are dependent on well-intentioned people who care about the environment not researching what they’re buying. governments & companies are advertising them and making laws in favor of them because they’re making money, not because they’re good. do not fall victim to consumerism. they are banking on you not knowing any better.

Modern Alchemists Turn Airborne CO2 into Diamonds

Each carat removes 20 tons of greenhouse gas from the sky, entrepreneurs say

The idea of collecting CO2 from the sky and trapping it in valuable products before it can warm the Earth is a seductive marketing strategy. Especially for an industry that sells precious items that last “forever.”

That, in a nutshell, describes the global diamond trade.

Now, two companies are selling diamonds made in a laboratory from CO2 that once circled the Earth.

The sales pitch can be stunning. As Ryan Shearman, the founder and CEO of a New York-based company called Aether, recently explained to a reporter for Vogue magazine: Each carat of a diamond removes 20 tons of CO2. That, he said, is more invisible gas than the average person produces in a year.

With the purchase of a 2-carat diamond, Shearman pointed out, “you’re essentially offsetting 2 ½ years of your life.”

What is HVAC and how it works?

HVAC, or heating, ventilation, and air conditioning, is a system that is designed to maintain indoor air quality and temperature within a particular building or space. The system comprises several components that work together to ensure optimal heating, cooling, and ventilation. This blog will discuss what HVAC is, its various components, and how it works.

What is HVAC?

HVAC is an acronym that stands for Heating, Ventilation, and Air Conditioning. The primary function of the system is to regulate the temperature and air quality within a building or space. HVAC systems are found in a wide range of settings, including residential, commercial, and industrial buildings.

HVAC Components

An HVAC system is made up of several components that work together to achieve its primary function. The main components of an HVAC system include:

1. Furnace or boiler: This is part of the system that provides heating. Furnaces use natural gas, propane, or electricity to generate heat, while boilers use water or steam.

2. Air Conditioner: This component of the system provides cooling. Air conditioners use refrigerant to absorb heat from the indoor air and transfer it outside.

3. Heat Pump: A heat pump is an all-in-one heating and cooling system that transfers heat from one location to another. In the summer, it removes heat from indoor air to cool the space, and in the winter, it pulls heat from outdoor air to warm the space.

4. Ducts: Ducts are channels that transport air throughout the building. They distribute heated or cooled air from the furnace, air conditioner, or heat pump to different rooms.

5. Thermostat: A thermostat is a device that controls the temperature of the HVAC system. It turns the system on and off and regulates the temperature based on the desired settings.

6. Air Handler: The air handler is a component of the HVAC system that regulates the circulation of air. It contains a blower that pushes air through the ducts and filters that remove contaminants from the air.

What is the HVAC Procedure?

HVAC systems work by using the laws of thermodynamics to regulate the temperature and air quality within a space. The laws of thermodynamics state that heat flows from warmer to cooler areas and that energy cannot be created or destroyed, only transferred. HVAC systems use this principle to transfer heat from one location to another and to maintain a constant temperature within the space.

The process of heating and cooling starts with the furnace or air conditioner. In the case of a furnace, natural gas or propane is burned to produce heat. This heat is then transferred to the air handler, where it is distributed through the ducts to the different rooms in the building. In the case of an air conditioner, the refrigerant absorbs heat from the indoor air and transfers it outside, leaving cool air to be distributed through the ducts.

The thermostat is the device that controls the temperature of the HVAC system. It is set to the desired temperature, and when the temperature falls below or rises above that setting, it sends a signal to the furnace, air conditioner, or heat pump to turn on or off. The thermostat also regulates the fan in the air handler, ensuring that the heated or cooled air is distributed evenly throughout the building.

Ducts are the channels that transport heated or cooled air throughout the building. They are usually made of metal or fibreglass and can be rectangular, round, or oval in shape. The ducts are connected to the air handler and distribute air to the different rooms in the building.

The air handler is the component of the HVAC system that regulates the circulation of air. It contains a blower that pushes air through the ducts and filters that remove contaminants from the air. The air handler also contains a heat exchanger, which helps transfer heat from the furnace to the air handler.

Conclusion: The HVAC system is an essential component of modern buildings and homes. It provides comfortable indoor air quality and thermal comfort.

Inside Charm Industrial's big bet on corn stalks for carbon removal

Inside Charm Industrial’s big bet on corn stalks for carbon removal

Good News Notes: “In recent weeks, a crew of staffers from a company called Charm Industrial have been working on the edge of Kansas corn fields, moving rolled bales of stalks, leaves, husks, and tassels up to a white semi-trailer. Inside, a contraption called a pyrolyzer uses high temperatures in the absence of oxygen to break down the plant material into a mix of biochar and bio-oil. The former…

We use chemicals for more or less ‘everything’. Now we have to find smarter ways of making them - Technology Org

We use chemicals for more or less ‘everything’. Now we have to find smarter ways of making them - Technology Org

Did you know the chemical industry supplies products to virtually all other value chains, including the food, construction, health and transport sectors? All these industries now have to renew themselves as part of the green transition, and SINTEF is working to help them.

The demand for innovative and greener chemical manufacturing has been clear for some time and represents a key aspect of the green transition in Norway and Europe. The chemical industry must undergo radical change, but how will this change take place?

Today, the chemical industry supplies products to virtually all other value chains, including the food, construction, health, and transport sectors. As chemicals become more expensive, this affects consumer prices throughout society. Across Europe, increases in the price of oil, gas, and energy are impacting all chemical manufacturing processes because these are commonly very energy-demanding.

Green chemical manufacture is just one area of investment in what the EU defines as its ‘twin transition’, which involves identifying new, non-fossil raw materials, promoting by-product utilisation, and accelerating the electrification of manufacturing processes.

At SINTEF Industry, where I work, we’re coordinating a project called ELOXYCHEM that is investigating alternatives to our conventional thermochemical manufacturing processes. ELOXYCHEM is an abbreviation for Electrochemical Oxidation of Cyclic and Biogenic Substrates for high-efficiency production of organic CHEMicals.

My team is investigating whether we can manufacture a variety of acids (carboxylic acids, in particular) using energy-saving processes. These acids are a key raw material in producing paints and varnishes, catalytic converters, fine chemicals, agricultural chemicals, scents, pigments and much more. What is special here is that we want to manufacture them using the waste products from other chemical manufacturing processes.

We will also look into poorly exploited by-products from biorefinery processes, so-called side streams, to manufacture chemicals of greater value. If we succeed, there will be multiple benefits including converting waste materials into a resource, energy savings, and a wealth generation boost with increased sustainability.

The ELOXYCHEM project will involve a study of three different manufacturing processes, where one line of investigation will conclude with a pilot facility as a precursor to chemical manufacture at industrial scale. SINTEF Industry will build the pilot facility in Trondheim and will later be transferred to one of the project partners, Evonik Operations in Germany. Here, both the equipment and the process will be tested for two years with a view to commercialisation and major upscaling.

The second strand of the project will involve the development of an eco-friendly process designed to produce approximately the same interim products from other industrial residual products.

Innovative technologies of the type that we are aiming to develop as part of the ELOXYCHEM project have the potential to produce not only familiar, but also new and exciting, building blocks for the chemical industry in much more sustainable ways by reducing greenhouse gas emissions, energy consumption and chemical waste.

Finally, the project will develop a so-called ‘digital twin’ of the manufacturing facility. This will be used to plan production using available energy sources in the smartest possible way. Since production will be powered by renewable energy sources alone, planning must take into account the intermittent nature of electricity supplies from wind and solar power, which may impact on the process.

Tree Planting to Address Climate Change

You may have noticed that we are not doing much about climate change. People wave their arms and say electric vehicles, to be powered by solar energy will solve the problem. Thence, having found the solution they do nothing. They also do not realize that a lot of fossil fuel is consumed to make electric vehicles and their batteries. Then there is the question of the electricity required. If you…

“Methane is responsible for 25% of today’s global warming, and we can’t limit future warming to 2 degrees Celsius if we don’t drastically cut those emissions," said Ilissa Ocko, a senior climate scientist at the Environmental Defense Fund, a group that campaigns for climate action. "We have the tools to cut methane in half and the faster we do that, the better off our climate and communities will be.”
