Comment on Building a dome to protect a city, farm, factory, refinery, facility, moon city, mars facility

https://www.researchgate.net/post/If_I_were_to_make_a_dome_to_protect_a_city_how_would_I_proceed Valentin Bogatu   Interesting question. It makes me wonder if you make money selling fabric.   But seriously, why would you? On Mars and the moon, yes. Most countries and cities and groups in the world can barely afford to live. They carry umbrellas. Their houses and cars and buildings have roofs. They wear

Carrot Museum typo generates these thoughts about global cooperation and investing in global communities

Hello Carrot Museum Reader, I was looking for information on the structure of carrot seeds and came to your Carrot Museum page, http://www.carrotmuseum.co.uk/seeds.html Should it say, “The seeds are very small, on average between 1 and 2 mm in length, and brownish is colour.”? I had no idea it was so complicated to get seeds

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 Earthquake Seismograph Using Bismuth Magnetic Levitator – about state of the art in low cost gravitational detector arrays

Earthquake seismograph using bismuth magnetic levitator as sensor at https://www.youtube.com/watch?v=aIANNzpec7Y Tomislav Stimac, The “standard” still for accelerometers is the small but global network of super conducting gravimeters (SGs). They use liquid helium cooled niobium magnetically levitated spheres as the test mass. The sensitivity is about 0.1 nanometers per second squared (nm/s2) at 1 sample per second.

Comment on Hubble vs Amateur Astrophotography

Hubble vs. Amateur Astrophotographer (27 Aug 2021) at https://www.youtube.com/watch?v=0QcJaD9klDc I had to look a bit, but eventually found a description of the camera and exposure for that original image of “Pillars of Creation” at https://hubblesite.org/mission-and-telescope/mission-timeline#h4-deab74a9-f038-4a74-9313-425d13e71747 with more detail at https://hubblesite.org/contents/news-releases/1995/news-1995-44.html then some images at https://hubblesite.org/contents/media/images/1995/44/351-Image.html?news=true Like usual, Hubble media people dominate sharing on their site,

Comment on Telescope prices and sharing

What YOU Can SEE Through a $1 Billion, $32,000 and an $800 Telescope! https://www.youtube.com/watch?v=VwoII9TQd8k There are many countries with LOTS of people where $800 is more than the median annual income. And many more countries and many more people where $800 is more than monthly income. So here you are, posting a video that could

Self reproducing robot societies that live in the desert and convert sunlight to cities

I have had deserts on my mind a lot over the last few decades.  All during the 1980’s I worked on populations forecasts and issues in Africa, then the Famine Early Warning Systems (FEWS.net), then global climate change.  I sort of keep up with any efforts to turn those vast areas into something more suitable

Comment on “Ion Engine 2.0” – many people interested, and posting things, but not working together globally

Ion Engine 2.0 at https://www.youtube.com/watch?v=OSt1-JsDyGs (“electric wind” OR “ionic wind”) has 574,000 entry points (Google, 9 Oct 2021) (“electric wind” OR “ionic wind”) site:arxiv.org has 310 entry points (“electric wind” OR “ionic wind”) site:youtube.com has 141,000 entry points And they are not all working together globally.

Comment on “Floating under a levitating liquid” and related issues

Floating under a levitating liquid at https://www.youtube.com/watch?v=bodsuTucSxQ and https://www.nature.com/articles/s41586-020-2643-8 (for pay, just for reference) This is not science and sharing, but what I have come to call “eye candy”. Pretty pictures and people playing with phenomena, but not showing the context and background. You start with showing the whole of the apparatus, explain the parts,

Comment on Making Petrified Lightning – application to solar system colonization, global needs and new industries

TheBackyardScientist,  Making Petrified Lightning …with electricity? at https://www.youtube.com/watch?v=m7YznIKe7bU 3D printing metal. You can use metal or glass powders, control the current, and randomly choose next points – probably run on Arduino. You have all the skills and stuff mostly. Maybe someone already suggested. You might invent a way for YouTube viewers to work together, combine
