# Mars and moon and space need atomic power – shipping to Mars example

SpaceX Starship can return from Mars without surface refilling at https://www.youtube.com/watch?v=u55zpE4r-_Y The engineering design and manufacturing costs for atomic power are a lot less than the cost of hauling chemical or solar panels to Mars. Do the numbers and see what it is worth to spend on lightweight atomic power units and technologies. A few ten

# Comment on plasma cutting video by Jason Michael Saunders, referring to 3D printed rockets

Comment on YouTube Jason, I watched this Genius of 3D Printed Rockets video the other day. They are using plasma discharge heating, but it is not very well controlled at all. They say “it works really precisely”, but it throws off heat and light and bits of wire, and fluctuates a lot. It only needs

# Thermodynamic Clocks – Time reversible systems, quality, gravitational detectors, solar system coordination

Shawn, Thank you for thinking of me, and sharing. The gravitational energy density (and the usually much smaller magnetic, electric and thermodynamic energy densities) control the rate of chemical, atomic and nuclear events at any location.  The most often used phenomena are “gravitational time dilation”, “relativistic or general relativistic corrections (from velocity and gravity)”.  An

# Comment on The 49 dollar, 500 WattHour eBike Battery video

https://www.youtube.com/watch?v=0FwA_s9Ovxc You talk about motivations for watching and DIY at about minute 14. The reason I am watching is I have a lifetime of learning how things work, what they can do, and how to put them into different combinations. Often the off-the-shelf parts don’t fit, or are overkill or too expensive. Mostly they just

# Solar system colonization – needs and opportunities, “working globally” becomes “working solar system wide”

With LEDs going to lower and lower energies, moving electrons is probably less expensive than digging holes and trying to concentrate the rather thin light on Mars. I was gathering what groups and resources are needed to send small nuclear packages to Mars to provide the energy needed. The old dream of atomic energy was

# Merging and upgrading sensor networks towards new industries and materials

Shawn, The atmospheric gravitational noise is much larger than the signals from the subsurface (usually). The noise in that gravimeter you want to buy is mostly atmospheric and thermal radiation field connected. Calibrate it against the sun and moon first. Then against 3D near realtime atmospheric models. (Climate and meteorology are just atmospheric, and the

Windows USB GPS Device Based on UBlox Chip and UCenter Software https://www.youtube.com/watch?v=uJZHVKGrl6Y @Ali Zitouna Hamed, I am not sure what you mean by “base ntrip”. I made this long ago and have not used UBlox lately. Since then i have been working on software defined radios, electromagnetic interference, gravitational wave detection, imaging arrays for gravitational

# Comment on Aerodynamic Center and Center of Pressure

Alexander, https://www.youtube.com/watch?v=67eTLeNwLgE You are using what looks like to be a good computer tool for these calculations and visualizations. But you don’t explain your tools and give links to let others know what to use, or what you recommend. I watched your hysteresis video. It is really shaky and hard to watch. You could use

# Comment on Bessel Beams, Basis sets, Schrodinger equations, Particle-Antiparticle pairs as dark energy and matter

I was looking at Bessel beams and came across your work. You have some good methods and insights. I would like to read where you started. Three things I was thinking about. The Schrodinger equation is usually written in terms of spherical harmonics. But the Bessel functions could be used instead. Just as a basis.
