[Self] If you blended all 7.88 billion people on Earth into a fine goo (density of a human = 985 kg/m3, average human body mass = 62 kg), you would end up with a sphere of human goo just under 1 km

Request Can a 100W solar panel condense 8-10 gallons of water per day?
Are the claims in this post plausible?
# Built an atmospheric water generator from hardware store parts. Pulls 8-10 gallons of drinking water from the air per day. Here's the breakdown.
>Background: well ran dry last year, I had a family and no municipal water option. Started researching and ended up building this. Figured this community would appreciate the technical side.
>What it is: an atmospheric water generator. It works by pulling air across a cooled condenser coil, the moisture in the air condenses on the coil, drips into a collection tank, passes through a filter and comes out clean and drinkable. Same principle as the water that drips off your AC unit, just engineered specifically for drinking water production.
>Core components:
>A refrigeration compressor and condenser coil (I stripped mine from a junked mini fridge but you can buy these standalone)
>A fan to move air across the coil
>A collection tank, food grade only, this matters
>A basic carbon block filter on the output
>A float shutoff so it doesn't overflow
>My first two builds failed. First one had a wiring issue that killed the compressor. Second had a condenser loop that was too small and couldn't cool efficiently enough to get meaningful condensation. Third one worked and has been running daily for 8 months.
>I later added a 100w solar panel and a battery bank to run it off grid. Total power draw is low, similar to running a small fan, so the solar setup was not expensive.
>Output varies with humidity. On a typical Arizona summer day at around 25% humidity I get 8-10 gallons. On higher humidity days it does more. It is not a solution for extreme desert conditions but it works in most of the country.
>Happy to go deep on any part of the build. Also documented the whole process in my profile in case anyone wants to replicate it.

Request How long would it take to get to 75% the speed of light with an acceleration of one g?
I was reading a science fiction book, and in it humanity has the capability to build interstellar ships that can attain 75% the speed of light. Assuming it would be ideal to maintain an acceleration that mimics gravity on Earth, how long would it take to reach maximum velocity?

Request If the meteor that wiped out the dinosaurs was detected tomorrow, would we as a species be able to do anything about it?
Assume that the governments of the world work together without issue and all available resources are used to solve this problem. Work begins as soon as the asteroid can be detected and determined to be on a collision course with earth. Could it be destroyed/broken into smaller pieces/diverted/anything else?
If an asteroid of this size could be handled, what is the maximum size that we could manage?
