Here is the idea. If an air conditioner was powerful enough, with intake and exhaust designed properly, you can remove Coronavirus (or any virus) from the air by the A/C moving the air faster than normal in an upward direction. You want the air to circulate so fast that if someone sneezes the water droplets will remain inside the room only a few seconds before it is sucked out the ceiling vent. For cooling the room, the idea is cool air enters the room near the floor and the warmer air exits through a ceiling vent, the "return." For heating the room you would also introduce warm air through low floor-vents, then the exhaust exits through the return in the ceilin…

is there any other alternative to autocad?

Airships are known to have trouble taking off and landing in conditions with high winds. Could it be feasible to use a system of VTOL drones, that are scaled up versions of the RC models. To function as tugboats to guide airships along their approved takeoff and landing routes. Also in this era where transportation by truck and trains are becoming increasingly inefficient due to rising fossil fuel costs. Could it become feasible to deploy a fleet of airships to transport multiple tons of commodities and goods over long distances. Due to them offering better shipping MPG (miles per gallon) numbers in contrast to current day options which require more fuel.

Has anyone ever heard of any plans to transport water from flooded areas to drought-stricken areas? What would it cost to transport huge quantities of water a thousand miles? Maybe cheaper than desalinating sea water? The experts always stress conservation and water recycling. Every drop of rainwater needs to be saved. Every house in drought areas should be designed to channel rainwater down drains around the house for storage under the house. Parking lots, streets, and sidewalks in cities could also channel and save rainwater in underground storage. "But moving vast quantities of water is not simple or cheap, and thus not realistic, experts say. Mostly, it's t…

Two large circular magnets enwrapped with a lot of energy while spinning in opposite directions at a very fast speed while the like poles repel one another will create a warp drive. I don't have the Money to invent nor experiment on it so i am sharing it here if anyone is interested in investing to invent it?

I know now that making a full on vacuum airship is unfeasible for it's compressive properties. So why not just make a rigid airship that is evacuated enough that the hydrogen is no longer significantly dangerous to it's surroundings, using say 25-30% density of neutral hydrogen? What's the weakest compressive material I cod use for that? Could I, in practice make any rigid, non-curved part out of a honeycomb-like structure of LDH-cells? This could be revolutionary in creating lighter weight rigid parts where volume isn't too sensitive and lighter weight is an advantage. Can someone give me a formula(and tell me all the dependent/constant variables) to get real values…

Lighter than air ships have been made to float using light gasses such as hydrogen and helium. Hot air balloons reduce the density of air by heating it. I wonder if it would be possible to make an air ship float by emptying the air out of it instead of replacing that air with light gas.

Hi. On a recent flight, perhaps on an Embraer aircraft, noticed diffused flashing red lights on top of wings that I never saw before. Anyone knows ? Took a video but does not show the detail, I was unable to ask the pilot at exit. They are near the 'ends' of wings tops, a centered row of 12, aiming upwards ? Seem as diffuse as if the wing was translucent and lit from the inside. Just curious. L wingtip ooooooooo ooo =================== Main fuselage =================== ooo ooooooooo wingtip R Found a image on the web to better explain the location of those lights on top of wings.

Hi, In my situation, I am dealing with two ideal gases traveling down a pipe at the same bulk velocities. I am only considering a 1-D treatment at the moment and I would like to find out at which point the two gases should be considered a well mixed, homogeneous mixture. Would anyone know either the particular formulation or even the subject matter to consult to determine the well-mixing of gases? Thanks and regards.

Artemis 1, formally Artemis I and previously known as Exploration Mission-1, is an arranged uncrewed Moon-circling mission, the principal spaceflight in NASA's Artemis program, and the main trip of the organization's Space Launch System rocket and the total Orion space apparatus. What are your thoughts on this ? I wrote an article on this but advertising it here is against the rules.

Hello Everyone, I am in the learning face of Artificial Intelligence and looking for an online book. I have checked on google source but there are lots of books and I am confused between James V Stone and Vinod Chandra Author books whose names are Artificial Intelligence Engines: A Tutorial Introduction to the Mathematics of Deep Learning and Artificial Intelligence and Machine Learning 1st Edition. Can anyone tell me, Is the right choice for the beginner level?

is this at 1.55Volt LR41 battery and the current can come to microAmpe?

so, see .... The problem statement is really simple, make a 150mm max pen rocket, with solid engine(sugar and kno3 composition) but, it gotta achieve a min altitude of 10 meter, and land back ...... Things i think we'll need is , oxidizer fuel proportion thrust control, stabilization solution for balance, and many more and no electronics allowed, What u guys think ........

My old model car was'nt charging battery enough, first i thought it may be battery issue. but i recently replaced my battery with a new one so there are lesser chances of it. i first check online reasons behind no charging of car batteries and found that it may be due to alternator which may be not charging the battery. So i test alternator of my car, i wana know which is valid method of alternator testing? I found a blog on this https://www.scienceforums.net/topic/126940-how-to-test-battery-of-a-vehicle/

Could the advent of long rage ramjet powered artillery shells, Laser point defense, nuclear power, and light weight armor as used in aircraft carriers be used to bring back the battleship? New technologies would seem to indicate that a powerful battleship platform could again be an important part of the Navy, the idea of either redeploying old battleships and or redesigning the old battleships has been around a long time but vulnerability to air power and missiles has always stopped the idea from fruition. New technologies could turn that around. This development might be part of this. https://en.wikipedia.org/wiki/Trophy_(countermeasure)

Hello, I have a question regarding the manufacturing process of electronic components in the case of the silicon deposition and corrosion process. My biggest doubt is the behavior of the plasma interacting in the reactor, I don't know if it's correct I would like someone to help me. What I understood from the subject: If you look at the image, it shows a capacitor (in the simplified case, a PECVD or RIE plasma reactor) where the particles descend from the plate and then it will collide with the particles on the bottom plate, in this case it is in the middle where the plasma wants to pass. In practice we have three directions (vectors) x, y and z, the magnetic effect …

Hello, I'm new to this forum and hope that I'm posting in the correct sub-forum. My apologies if not. I was wondering if anyone has ever heard of anyone making a "perpetual" clock powered by batteries made with potassium chloride? In the past I found a website from someone who made and experimented with this type of clock. They had a working model of it. The clock wasn't really perpetual, but apparently was expected to run for a lifetime (or close to it). If I remember correctly the batteries were made in cardboard tubes and arranged around the clock. I also think that there might have been a glass dome covering the clock. I can't remember what the cloc…

It will store off-peak wind and solar electricity production as heated water for use in home heating. Sometimes you have an abundance of electricity in the grids that you cannot use anymore, and then you need to turn off the wind turbines,” said Wielgoss. “Where we are standing we can take in this electricity.” The 50-million-euro ($52 million) facility will have a thermal capacity of 200 Megawatts — enough to meet much of Berlin’…

I read that the most (however I'm not sure) efficient steam coal-fired train was 27% efficient in the past century 🙂 link: steam train thermal efficiency. (browse pages up to the Third Generation Steam(TGS)). So...I wonder if it's possible today to build biomass-fueled steam engines for bulky vehicles(agricultural etc...). Energy content of 1 liter of diesel is equivalent to 2.5 kg of wheat straw pellet(An example). BUT 1 liter of diesel costs around 1.5 u.s. dollars while 2.5 kg of wheat straw pellet is around 0.25 u.s. dollars. Problems can be: 1-wheat straw availability 2-power 3-volume I'll try to give some answers to t…

I have seen pretty recent studies about how scientists are using a liquid metal alloy to make co2 solid. I was thinking about applying this concept to cars. The idea is that the exhaust pipes direct the exhaust into a wide container containing the liquid metal, and the co2 reacts with the metal to form carbon flakes that adhere to the sides of the container. This allows the process to keep on going for a long time, which allows for drives that actually last for more than 10 seconds. One thing that might be a problem is all the other gasses, such as nitrogen oxide, that are part of the exhaust, which won't be turned into solid by the liquid metal. Another problem might be …

Possible nighttime counterpart to solar PV power generation. https://pubs.acs.org/doi/10.1021/acsphotonics.2c00223# Looks like it's got a ways to go in term of milliwatts per sq meter, but a cool idea (npi). Maybe would work better in deserts where the surface is losing a lot of heat to space.
