Cell Phone Powered By Urine 88

Posted by samzenpus from the want-to-use-my-phone? dept.
sciencehabit writes "The newest source of battery power for your cell phone is both cheap and abundant. Scientists report that microbial fuel cells using human urine can directly power a cell phone battery. However, the devices are not quite portable enough to come in handy during a marathon pub crawl. One consists of six, 4-inch-long ceramic cylinders; the other is a network of 25 smaller fuel cells borrowed from the team's waste-fueled EcoBot. And urine-powered conversations would have to be short and sweet. After 24 hours of charging, a Samsung phone stayed alive for 25 minutes—enough to send several texts and make a 6-minute, 20-second call."

DOJ: We Don't Need a Warrant To Track You 259

Posted by Soulskill from the well-we-don't-need-a-warrant-to-fire-you dept.
GovTechGuy writes "The Department of Justice maintains it does not need a warrant to track an individual using location data captured from their cellphone. 'Cellphone location records are currently lumped under Title 1 and Title 2 of the 1986 Electronic Communications Privacy Act (PL 99-508), which cover stored communications and call details. Accessing those types of information typically requires only a court order, rather than a warrant, as is required for the contents of a phone call or digital message under Title 3.' That has prompted Maine and Montana to pass laws banning warrantless cellphone tracking; unfortunately, Congress doesn't appear close to doing the same."

Pre-Dawn Wireless Emergency Alert Wakes Up NYC 382

Posted by Soulskill from the first-world-problems dept.
New submitter SkiTee94 writes "Many people, perhaps millions, in and around NYC were loudly awoken shortly before 4am this morning by an activation of the Wireless Emergency Alert system. As the New York Times is reporting, the alert was related to an ongoing search for a missing child. Given that the alert asked people to look out for a 'Tan Lexus ES300' with NY Plate 'GEX1377,' many New Yorkers are questioning the logic of waking up the whole city to ask them to look for a car. Normally such alerts are reserved for road-side signs. While emergency authorities have yet to give a precise reason for why the decision was made to wake up the city, many have taken the step of deactivating these alerts to avoid future jolting mid-slumber alarms (likely not the intended result of last night's exercise)."
