Lithium In Water "Curbs Suicide"

SamMichaels Meds in the drinking water (458 comments)

I don't remember which site had the story (I didn't see it in a quick search of /.), but in some cities drinking water contains trace elements of various pharmaceuticals. Since our waste water is processed and used again for drinking water, it's not being filtered out.

So we don't need to add in the meds....everyone else is already on so many meds that it's finding its way into the drinking water on its own.

What We Can Do About Massive Solar Flares

SamMichaels What's the actual problem? (224 comments)

Unless I missed it, TFA left out the technical details of the problem and was filled with FUD language instead.

From what I saw on wiki, it's a quasi-DC current. Why can't we just install massive inductors that give high impedance to 60hz and pass DC? Wouldn't that cost less than $45k? Don't we already have static drain chokes? How does this affect current lightning protection shunts (or when they say the protection circuits pop, is that to what they're referring)?

Linemen chime in!

Cornell Grad Students Go Ballooning (Again)

SamMichaels Up, up and away (58 comments)

What would be really neat is an ATV downlink on UHF so we could watch it. I've always wanted to see the transition where the blue sky disappears.

FYI, APRS is pretty much text messaging for amateur radio. The most popular use is reporting your position (which is what the balloon does), but it's an easy way to pass short digital messages....or even send an email if you're near one of the gateways.

Off topic, but semi-related because of APRS: AT Golden Packet Event. An APRS packet is relayed up the entire Appalachian Trail.

Verizon Promises 4G Wireless For Rural America

SamMichaels Antenna size (135 comments)

It's important to recognize that the size of the antenna is bigger at 700mhz. Remember the old phones with the antenna you extend? 1/4 wave at 700mhz is 4.2 inches. Compared to the 1.2 inches at 2.4ghz, I don't think manufacturers would be able to conceal it within the device and still get good performance.

Google's GeoEye-1 Takes Its First Pictures

SamMichaels Here's why... (152 comments)

I think they were aiming for the First United Church of Kutztown, but the coordinates were off. Rumor has it the abbreviation is written on the roof.
