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

A wave traveling between two parabolic antennas https://www.youtube.com/watch?v=v0cZjOIfwos You might try receiver-transmitter pairs, where each inverts the signal to build a standing wave. Use the final state inside the volume (arbitrary and time dependent if you want) as the constraint, then solve for the signal modifications needed at each site. I first saw this more

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

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

Counting Atoms with the Doppler Effect – Heterodyne Interferometer by Sam Zeloof at http://sam.zeloof.xyz https://www.youtube.com/watch?v=vPu6lN9yJOY Sam, I sent you an email about using this to replace the network of superconducting gravimeters with something more people can afford. You have several orders of magnitude available to you by very small adjustments. SGs cost several hundred thousand and

One linear regression is all that is needed to useg JPL Ephemeris to separate the sun moon from earth-based signals I want to repeat the SG network speed of gravity measurement I did in 2003 using all the current stations. I will also use the best of the broadband seismometers from IRIS.edu. Any absolute measurements,

https://www.facebook.com/groups/172438633343696 Dear Allsky, I went through over a thousand live webcams on the Internet to see what people are sharing live now. My estimate is somewhere around 10,000 overall. Many of them have half sky (show half the image with sky) and in those they will capture comets, meteors, satellites, stars, planets, planes and many

Marley, For the last 20 years or so, I have been tracking gravimeter developments, hoping one day they could be developed enough to use in low cost gravitational imaging arrays. I don’t have my notes on what I wrote to you. My memory is that I saw you were at “earth tide” sensitivity. That is

Some NOAA Visualizations Data Projections More Gravity Sun Moon Global Cooperation https://youtu.be/4waIa-2tMlY My comments and a few suggestions. Then another pitch for global cooperation, and for help with gravimeter arrays to scan the atmosphere, the oceans, the earth interior, the moon, sun and planets and moons. Richard Collins, Director, The Internet Foundation The video refers

I have been looking at the general situation of tracking and studying slow variations of fast signals. If you have a star, its main signal is likely electromagnetic or gravitational. You track its “colors” with an FFT or spectrometer, and perhaps its slow variations up to decades of years or longer. (“pulsar” OR “pulsars”) “MHz”
