diatomaceous earth will kill any crawling insect and it's so safe you can eat handfuls of it and buckets of the stuff are only about $25, it's used to filter swimming pool water

You are welcome Texas

Ok did the research, she "invented" the wheel, they have been using this method since at least 2007. Her method uses "a novel core-shell nanorod electrode with hydrogenated TiO2 (H-TiO2) core and polyaniline shell. H-TiO2 acts as the double layer electrostatic core. "

Not so novel: "Incorporating the utilization of carbon nanotubes cathode and TiO2 nanotubes anode in energy storage, a nonaqueous hybrid supercapacitor was developed in order to significantly increase the energy density of the supercapacitor."
http://www.ncbi.nlm.nih.gov/m/pubmed/18019169/

Also dr yat li which she claims was "supervising" her seems to think he invented it a year ago without her help. Notice his name is on this article with other doctors but her name is missing: "Hydrogenated TiO2 Nanotube Arrays for Supercapacitors"

She basically did a chemistry experiment that had already been done and published, she invented nothing

Surprised none of the top comments mentioned that this seems like complete BS. Greatest minds from Samsung, Apple, and every electric car company can't figure this out, but a 18 year old did, and she didnt demonstrate it running something useful like a smartphone or tablet, she demonstrates it working on a single LED that runs for days on a battery anyway, and the article is horribly light on details. Surprised this even made it on /. since it sounds like a April fool's joke or something from the onion: "teenager creates invention dozens of billion dollar companies have been researching for decades"

Roomba is right. They've been predicting robots taking over since the 70s. Remember all those robot articles in popular science back then? And what do we have now, 30+ years later? Roomba. Nothing has changed. Only place that has robots are factories and they're still millions of dollars. Robots might be great at moving items or going to an exact point and welding, but it will be many years before they get cheap and smart enough to think and react on their own to any situation. We can't even make SPAM filters that work perfectly and that's far simpler than building an iPhone. When most cars sold are self-driving then I will worry about robots taking over, but last I checked self driving cars aren't even for sale and google has been working on their's since 2005 http://en.m.wikipedia.org/wiki/Google_driverless_car

This. iTunes is worthless. iPhone will backup wirelessly to the PC, no need for a physical connection.

Ya because you have to plug your iphone in constantly. I've disabled this and iTunes doesn't pop up when I plug in the iPhone. Only reason I ever plug in the phone is to take photos and videos off of it. Other than that there's no need to plug it in to the PC, everything backups up wirelessly or to the cloud automatically.

Mounting things to light poles is 10,000 times more practical.

still better, faster, cheaper to go buy a metal pipe at home depot and build a gun for $20

For years, we have had a cut-out in ITAR 121 that applies to Open Source, it is due to a lawsuit that Phil Karn brought against the Federal Government. Thus, you can implement with impunity, and export to anywhere, as long as it's Open Source.

Rather than an encryption gateway, having your email client handle encryption avoids the problem of man-in-the-middle attacks between the gateway and the client.

I don't have much reason to encrypt, but Thunderbird has my certificate installed and does my digital signing. This is not unusual for a modern email client.

I find that hard to believe. I've owned one of these cheap chinese tablets, and the only thing it ran was a browser and even that was slow. Very few apps ran fast enough to be useable, and the only games that worked were 10+ years old like bejeweled. So while some people might buy these cheap tablets to "try out a tablet", it won't be long before they're throwing it across the room in frustration and wishing they just bought an ipad

Because we wanted cheaper solar, so when facts came out that the chinese was stealing the tech and selling it for nothing everyone cheered, except the US solar manufactures. Harley is a household name, we didnt wanna be riding Gofastlongtim bikes, so the US govt put a stop to that

I'd like to hear the answers to those questions too, and if I had mod points you would have all of them

Entire article is false, EPA changed the testing in 2008. Since 2008 they test mpg up to 80mph and accelerate at 8.5 miles per second, roughly 0-60 in 7 second

And they tell you if the filament is too old, because no one wants to print with ink or filament that is has been sitting in a cartridge for a whole long year
