Comment: Wavelength matters too? (Score 1) 327

by PaulBu (#48511463) Attached to: You're Doing It All Wrong: Solar Panels Should Face West, Not South

My first though without even reading the summary:

Of course pointing it to the South would "catch" more integrated spectrum, but not all of that can be converted to electricity efficiently (they are more efficient for longer wavelength), so it should not *hurt* much to till them westwards (or eastwards), where/when blue light ("useless for") is filtered by the atmosphere...

By the way, blue light is still absorbed/heats/damages the cells, but not gets converted to voltage. Or some such... ;-)

Aligning with peak demand might make more sense though.

+ - Woman of 24 found to have no cerebellum in her brain->

Submitted by Diggester
Diggester (2492316) writes "DON'T mind the gap. A woman has reached the age of 24 without anyone realising she was missing a large part of her brain. The case highlights just how adaptable the organ is.

The discovery was made when the woman was admitted to the Chinese PLA General Hospital of Jinan Military Area Command in Shandong Province complaining of dizziness and nausea. She told doctors she'd had problems walking steadily for most of her life, and her mother reported that she hadn't walked until she was 7 and that her speech only became intelligible at the age of 6."

Could be nice way of sidestepping the Chinese and their "rare earth" near-monopoly.

Judging from the author's names and affiliation, I quite doubt that it was their main motivation... :)

I think it was in the news recently, a lot, but not for their Linux contributions...

Though, maybe those were referenced too, along with some other contribs to MS, standards organisations, etc.

If anything, I am sure that someone is giving close and fresh look into SElinux parts right now...

If my cell phone can transmit 30 times farther, I'm guessing that the power will drain from the battery 30 times faster.

Assuming that your cellphone transmit unidirectionally (as it's natural for a cellphone to do!), is not getting 30 times the 'r' requires 'r^2' more power, i.e., your battery will drain 900 times faster? ;-)
