“Can Additive Manufacturing help fight Climate Change?”

 

Additive manufacturing is any maker’s dream. But did you know that it could also help fight global warming? Well, because additive manufacturing makes items by adding layer upon layer of material, it is not limited by traditional manufacturing processes. Therefore, less material can be used, and slimmer, more efficient designs can be achieved. As a result, manufacturing will become less resource intensive, and carbon emissions can be reduced.

Urgent Report: Humanity is not Investing Enough into Renewable Energy!

“How much more renewable energy do we exactly need to build?”

 

Humanity is in big trouble. Although we have been investing more in renewable energy than ever before, at our current rates it is still not enough. A paper by Ken Caldeira at the Carnegie Institute for Science has calculated that the entire world will need to 1.1 gigawatts of clean energy per day to limit climate change levels to be below 2 degrees Celsius. But against this monumental number, we are only adding around 15% of that! If we keep going at this pace, it will take four centuries to completely overhaul our energy system, which could lead to drastic consequences.

“What exactly is Air Pollution?”

 

Air Pollution is one of the most discussed topics in both scientific research and public policy. But what is it exactly? Well, when some form of chemical activity occurs, whether it be in a manufacturing process or the aftermath of an internal combustion engine, chemicals may be released into the air. And some of these chemicals such as carbon dioxide and carbon monoxide may be toxic to human health, thereby creating air pollution!

“How can we detect air pollution?”

 

Air pollution is one of the most harmful side effects of industrialized activity. Whether it be shipping in the Port of Los Angeles, manufacturing in Shenzhen, or vehicular smog in Delhi, air pollution can seriously destroy public health. But how can we use our engineering mindset to quantify this? Well, we know that sensors are commonly used for detection, engineers have created Air Pollution Sensors to solve this crisis. Air Pollution Sensors can be configured to detect five types of pollutants: ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrous oxide.

Almonds and Water Use

“How much water do Almonds use?”

 

One of the most popular crops in my home state of California is the Almond. Almonds are loved around the world for their nutritional benefits and plant-based protein. However, like any bit of produce, they also require resources to grow. Popular sources have stated that each nut requires a whopping 1.1 gallons (around 4.16 liters) to grow! However, that only tells a part of the story. It turns out that Almond trees have multiple uses such as removing pollution from the air and being turned into firewood. In fact, the Almond industry has grown by 60% in California since the 90s while its water consumption has remained flat. Therefore, when reading about information online, be sure to always check empirical facts.

“How will Climate Change make renewable energy adoption in the Caribbean More Difficult?”

 

Caribbean Nations are doing their part to combat Climate Change by adopting renewable energy. However, this will become more difficult as global temperatures rise, since the increased frequency of rainfalls and hurricanes make installations more difficult. But by adopting climate change adapted technology such as hurricane-resistant wind turbines, the Caribbean will be able to build itself into sustainability.

“How can we measure the point in which saturation occurs?”

 

When it gets humid outside, it’s very easy for moisture to appear on surfaces. However, why does that happen? Well, the answer lies in a most interesting property called the Dew Point. The dew point is the temperature at which the gas in a given area will condense into a liquid. If an object cooler than this point comes in contact with air, then it is possible for dew to form. HVAC system engineers must keep this value in mind when designing dehumidifier equipment.
