I have a hard time taking 3-D printing of houses seriously. It may have value in some structural applications, but in housing there just isn't much potential cost benefit. Many years ago, when I was discussing packed earth, straw, and other "green and cheap" buildings, it was pointed out to me by an ...

I have used COMSOL on a few applications over the years. It will do anything, but not necessary do it easily. It requires a lot of time on any complicated simulation, such as yours. I would not recommend attempting using it unless you have good technical support from someone with experience with the ...

Mr. Vasicek's discussion is technically correct, but simply a second or third order process in the CO2 mass balance. While obviously a good chemist, he has not demonstrated any knowledge of continuum systems in heat and mass transfer, much less climate science per se. Lakes and oceans are not saturated ...

The climate is changing, and it is being driven by greenhouse gas emissions. Yes, I know there is a collection of "evidence" out there "debunking" climate change. 25 years ago when it first started getting headlines, there was a lot of hokey research and predictions, and I personally debated against ...

You can check out: Christianson, R, S. Hutchinson and G. Brown, 2015. Curve Number Estimation Accuracy on Disturbed and Undisturbed Soils, J. Hydrol. Eng.. The basic conclusion is that for disturbed soils the normal soil mapping is a poor predictor of the disturbed soil. Instead, you should ...
