Comment on Can You Modify A Car To Save Fuel?

Can You Modify A Car To Save Fuel? – Fifth Gear https://www.youtube.com/watch?v=39g5D7h7jf8 The weight reduction impact shows up if you start and stop as part of a test. Aerodynamic drag goes as the density of air times the velocity squared. You should have waited for a day identical to the first. You guys are in

Comment on Quantifying the potential causes of Neanderthal extinction

Axel, Thank you for sharing your paper.  Academia.edu notified me that you had uploaded it.  I read it this morning, then read it again.  I wish your model was in a form that could be shared more easily. I follow groups using the internet.  I am interested in how people approach complex problems, and the

Answering a question – Is it possible to accelerate neutrons?

Can ever neutrons be directly accelerated by any means of energy ? https://www.researchgate.net/post/Can-Ever-neutrons-be-directly-accelerated-by-any-means-of-energy Riccardo Bernardini This is an interesting article. But search “neutron accelerator” on Google and you get many tens of thousands of entry points. The neutron has a magnetic moment, so is affected by any magnetic gradient. Actually by any energy density gradient

Comment on Why does light slow down in water

https://www.youtube.com/watch?v=CUjt36SD3h8 You explained part of the problem, but not why it follows those paths. That takes mathematics, and you did not use any. Memorizing animations might seem a way to learn processes and use them later, but equations, measurements and precise models are better. You could have at least shown the equations, and more, provided

Comment on Collaboration for Global Problem Solving: The Case for Food

https://www.youtube.com/watch?v=anOEGXpppIk Too bad the person running the camera did not frame the slides so they could be read. You had some good things to say, but no links to resources, nor framework. Your EAT Foundation is not linked, nor the Atkinson Center. YouTube can be a place for discussion and collaboration, but it takes a

Comment on a product on Amazon

Digital Voice Recorder; Modea Portable Digital, USB Disk Audio Voice Recorder https://www.amazon.com/gp/product/B07CHNBJQR I wanted a low cost way to record while the recorder is plugged in. I hate batteries, and charging and guessing when the battery will fail. So I specifically looked for one that said “will record while charging”. Someone complained bitterly there are

Comment on Electret Mic: How it Works and How to Connect it to a Computer

https://www.youtube.com/watch?v=oqLhvg0I2BU Your microphone link says that particular model is “discontinued”. I use Amazon for convenience and there are several electret microphone items worth seeing at https://www.amazon.com/electret-microphone/s?k=electret+microphone They have the electret microphone elements, but there are also some “electret microphone amplifier” breakout boards that are inexpensive and might work. I ordered some, but have not tried

Comment on Applied Sciences Video – Measuring Human Digestive Efficiency vs a flame

https://www.youtube.com/watch?v=9wZ0wTqJIxY I am fairly certain you are just seeing the fiber that is concentrated in the feces. It has about the same heating value per unit mass as the original, but indigestible. Most all the sugars, starches and lighter fats are likely to be used for energy – converted to energy, CO2 and water with

Comment on Industrial applications of pulsed power technology

https://www.researchgate.net/publication/3340967_Industrial_applications_of_pulsed_power_technology_IEEE_Trans_Dielecrt_Electr_Insul/comments Thanks for gathering this together. But the last decades or so, the cost of high power, high dI/dt controls has dropped considerably – drones, 3D printers, PWM servos, robotics, vehicles. I have only looked at a few areas so far. What you sort of missed was the sensor and control and modeling side. Atmospheric

Comment on Nuclear Desalination Report

http://Article Nuclear Desalination: A State-of-the-Art Review Thank you for putting this together. This is a clear, and fairly complete, review of the issues, economics, performance and maintenance of nuclear desalination processors. I just wish that each site’s operational, financial and social impacts were public on the Internet in a form for comparison and optimization. Encouraging
