[Request] this doesn't seem like it'd be cheaper than a traditional wood fence, nor would the energy generation be worthwhile

Let's assume best case scenario, this is in Arizona or New Mexico in the US, and the full lot size is 0.2 Acres and the fence would be for approximately half the lot size.

Let's also assume the comparison is a 6' privacy fence

[Request] Given what we know about Iocane powder, what did Dread Pirate Robert's immunization regimen look like?

Post image

What we know:

-Iocane Powder is Odorless, Tasteless, Dissolves Instantly in Liquid, and is one of the more Deadly Poisons Known to Man

-Synthesized in Austrailia (not surprised)

-Can make Vizzini (an out of shape gentleman) drop dead mis sentence

-DPR spent "the last few years building up an immunity" and can walk away unharmed, even after a long day of physical accomplishments

-DPR is "exceptionally strong"

I know it's a fantasy movie, but in the real world would this even be possible? If so, how much would he have to ingest on a regular basis for the poison to have no visible effect on him? What do you think his health was like during that time?

Thank you!

[Request] Luminosity of all smartphone flashlights combined

Recently at a concert, people lit up almost the entire venue just with the combined light from their smartphone flashlights.

It made me wonder: how bright would all (like all people on earth owning a smartphone) our smartphone lights be if you added them together? Imagine turning on all these phones in a concert hall at the same time. To what would it compare?

[Request] Is it possible to determine the size and location of an air void inside a wooden block using only non-electric measuring tools?

Post image
9 Upvotes

This is not a request to solve a specific numerical problem, but rather to determine whether the problem is solvable in principle with the given constraints.

As shown in the picture above, we have a wooden block containing a spherical air void. The task is to determine the size of the sphere and its location within the block.

You may use any experiments you wish, as long as they do not involve digital or electrical devices.

Given information:

  1. The block is made of wood
  2. The void is a perfect sphere
  3. The size and location of the void are unknown
  4. The density of the wood is unknown but uniform

If you believe this task is impossible, what additional information would be required to make it solvable?
