How Many Pieces of Paper Can a Single Solar Panel Produce in a Single Day?
“What is the amount of paper able to be produced by a single solar panel in a single day?”
Every industrial process in this world takes energy, and paper production is no different. According to calculations done by Stanford University, a single sheet of paper takes 138.0 kJ to produce. Since a typical solar panel can produce one kilowatt-hour (equivalent to 3600 kJ) in a single day, it can produce around 26 pieces of paper! Keep in mind that this is just a single solar panel, so a whole array will be able to produce much more. This is How Many Pieces of Paper Can a Single Solar Panel Produce in a Single Day.
The Works of Marie M. Daly
“Why is the work of Marie M. Daly (the first Black American Woman to receive a Ph.D. in Chemistry in the United States) so important?”
During her lifetime, Marie M. Daly was a prolific scientist. Trained as a Biochemist from Columbia University, she sought to understand the fundamental workings of the human body. During her career, she uncovered many of its secrets such as methods for the fractionalization of nuclear material to separate the essentials of a cell into its various components, The role of ribonucleoprotein in protein synthesis (which was later used in Watson and Crick’s discoveries of DNA structure), as well as work on cholesterol, hypertension, and creatine. In short, The Works of Marie M. Daly are paramount to our collective understanding of human biochemistry.

Ultracapacitors for EVs
“What is one possible way to speed up EV recharge times?”
In order to achieve deep-decarbonization of transportation, the global vehicle fleet needs to become much more electrified. However, the long recharge times associated with electric vehicles are a roadblock for this to happen. One way to solve this would be to implement Ultracapacitors for EVs. Ultracapacitors have quick recharge times, low weight, and low degradation, making them a formidable option. The downside is that manny ultracapacitors lack the storage capacity found in traditional solid-state batteries. But if this problem gets solved, then expect a paradigm shift in the EV industry!

Low Carbon Fuel Standards
“How can we ensure that our vehicles burn cleaner fuel?”
Vehicles gasoline is extremely pollutive. However, through a little bit of policy and technology, we can overcome this. If we were to mandate that all petroleum in vehicles only emit a certain amount of carbon per volumetric unit, it would force companies to innovate and invent/distribute cleaner fuel. This usually involves mixing or replacing petroleum in the vehicle with low-carbon alternatives such as biofuels. This is known as a Low Carbon Fuel Standard and is used in countries all over the world to control emissions.
Why Wind Turbines Can Provide Resiliency During Cold Waves
“How can wind turbines be useful for communities during extra cold times?”
During times of cold waves, traditional energy generation potential goes down. But this usually coincides with an increase of wind, which heightens the energy potential for wind turbines. This is Why Wind Turbines Can Provide Resiliency During Cold Waves.
Why Hydrogen Fuel Cells Work for Heavy Trucking
“Why might hydrogen fuels cells be the future of heavy trucking?”
In order to decarbonize heavy trucking freight transport, the replacement system needs to have high energy density and low weight so it doesn’t bog down the cars on their long rides. This way Hydrogen Fuel Cells would be perfect due to satisfying both of these. This is Why Hydrogen Fuel Cells Work for Heavy Trucking.
Probabilistic Risk Assessment
“How can we determine the risk of an infrastructure project?”
Grand infrastructure projects such as nuclear power plants, high-speed rail, and hydroelectric dams are essential for the backbone of modern human civilization. However, there if there are any faults in these systems, then the consequences could be very severe. As a result, these projects have to undergo Probabilistic Risk Assessment, which entails determining the magnitude of possible consequences and their likelihood suing quantitative analysis.
