russ_watters replied to the thread Will anyone alive today see a permanent colony on the Moon or Mars?.For what it's worth, this criteria doesn't alter my answer. I don't think there's a difference in challenge level. -

I cast my vote assuming "permanent colony" implies people in general would be living their full life on Mars or on the Moon, including... -

The poll question could be a trick question and actually be about radical expansion of the human lifespan. :wink:

russ_watters replied to the thread Will anyone alive today see a permanent colony on the Moon or Mars?.What do you mean? We'll suffocate if we fly too high! Anyway, I voted no. Mars is nigh on impossible. The moon is possible, but...

I've had pretty good luck with them. Not so with the 18650's though. They seem to have declined in quality in the last few years. I...

russ_watters replied to the thread Undergrad Why is thermal energy treated differently than other kinds of energy?.It's also not an arbitrary convention/just a name, like East/West or for that matter, positive and negative charge. You can't swap high...

russ_watters replied to the thread Li-Ion Battery Quality Report.That's interesting but there are a bunch of no-name 1.5V AA rechargeable Li-Ion batteries/chargers for sale on Amazon. Any thoughts on...

Erm... As far as I know there is just no suitable Li-based chemistry for the usual voltages associated with the AA format.

Erm... That's a bit different. Li-ion cells (rechargeable) works around 3.7V Standard AA (Zinc-Carbon, non-rechargeable) is around 1.5V...
