Unfortunately, we live in a world where public opinion (skewed by fossil fuel companies or otherwise) is a huge driving force. We can lament what the world would be like if only people were more knowledgeable, but at the end of the day it&#

I don't work as a physicist (but I got my degree in Engineering Physics @ CU-Boulder, 2009) and I went to see Interstellar in IMAX on opening night. I really enjoyed it overall, and the scenes involving the realistically-rendered black

Looking at the provided fusion flowchart: https://www1.grc.nasa.gov/wp-content/uploads/Steinetz-Fusion... It appears to be the same mechanism as neutronic high-energy fusion. An energetic neutron gets kicked out,

Napkin math on power density and compactness: Theoretical LENR device would be comparable to an RTG [1] because at high heat the device would melt itself. It's more about a trickle of stable power, rather than being used as a cell of a

I got my undergrad in Engineering Physics from CU-Boulder and talked with many professors about fusion research (plus keeping up with developments since then). Putting aside all the controversy of LENR (low-energy nuclear reactions, the off

I graduated from CU-Boulder in 2009 and have lived in the Denver-metro area ever since. I could very easily see Amazon drawn to the Boulder-Longmont-Lafayette triangle if not in Denver proper. Lots of growth here in the last 5 years especia

I probably should have clarified that my analogy was coming from a perspective of super-deterministic[1] compatibilism[2]. In the absence of knowing the truth, I feel that solution is the best model / explanation. It strips away the &#
