Comment: FOV question (Score 1) 25 25

Anyone know what the FOV of a human is?

I assume that moving your eyes while wearing a headset doesn't work, instead, you have to move your whole head. So the FOV ought to be that of a human who is only looking forward. Increasing or decreasing the FOV would surely create dis-orientation for the user.

Comment: Question: global power network (Score 1) 502 502

Has anyone considered a global, rather than national, power network? I would imagine something like that would allow solar energy generated during the day to be used elsewhere, without the problems of peak demand that can currently happen.

IAMAP, but I'd have thought that the galaxy would flatten everything out to a certain degree, but as you move to smaller scales, local gravity conditions would take over, for example: the planets being more tightly bound to the sun than they are to the Milky Way as a whole.

Q for a physic-y person - The earth orbits around the sun's equator, but its own equator is at an angle to the sun-planet plane (hence, seasons). Does the moon, then orbit around earth's equator (at an angle to the sun), or in the same plane as the sun's equator (or some other plane entirely)?

In a search and rescue situation I can imagine a team of people each with one of these devices, as well as GPS. If the devices can communicate with each other (as a mesh network) they could pinpoint location based on the different times they see the same signal. Furthermore, if the mesh eventually reaches a position where GPS is available, this signal could then be used to establish an anchor position.

Finally, and I don't know if this was covered, but presumably this system would also allow for vertical location to be found as well.

Keck clip they are.
While these are almost certainly patented, maybe by changing the material clips could be printed without legal trouble. Keck clips can fall apart if exposed to (eg) HCl gas, so printing PTFE versions would be useful.
I like the adaptor idea - and it could be extended to any labware if someone figures out how to print glass. No more searching for that B24 condensor!
