Dust off your high-school physics knowledge for a moment, and recall the difference between batteries and capacitors. The former can store a lot of energy but take a long time to charge, while capacitors have more limited storage but can be charged in seconds. Lately, engineers have been developing devices that combine the best attributes of both: so-called supercapacitors that charge quickly and have improved storage capacity - some of which have been in use for several years in China, in fast-charging public buses.

Ryan Bell knows that his best friend, fellow captain, and closest confidant will be 60 feet, 6 inches away. It's just a matter of whether David Viselli is behind the plate or atop the pitcher's mound. Either way, Bell says, the two Burlington Township High School baseball stars will see the game the same way. "It's almost like we're the same person," Bell said. "When he's pitching and I'm catching, he never shakes me off. When I'm pitching and he's catching, I never shake him off. "We're both into the game on every pitch.

TOKYO - All Nippon Airways and Japan Airlines said they replaced lithium-ion batteries in their Boeing 787 Dreamliners on multiple occasions before a battery-overheating incident led to the worldwide grounding of the jets. ANA said Wednesday that it replaced batteries on its 787 aircraft about 10 times because they failed to charge properly or showed other problems and that it informed Boeing about the swaps. Japan Airlines said it had also replaced lithium-ion batteries on its 787 jets, but couldn't immediately give details.

U.S. officials and Boeing Co. are investigating whether defective batteries from the same batch caused incidents in two 787 Dreamliners that triggered the plane's worldwide grounding, according to two people familiar with the incidents. If that proves to be true, it could show a flaw causing the incidents was confined to a small number of 787s, rather than a systemic fault with the plane's engineering, design, or manufacturing, and could speed the resumption of flights. The sources, who were not authorized to speak publicly, said the information was preliminary and investigators had not ruled out other causes.

HOW ARE you going to keep your mobile phone up and running if Hurricane Sandy hits us with a wallop? Gizmo Guy has suggestions to help get you through the worst of the storm. First, prep your phone for hardship duty. Fully run that battery down - watching videos does that job quickest - then recharge the battery. While charging, venture into the settings and shut off all the "polling" features - Wi-Fi, Bluetooth and Navigation - buzzing in the background, sucking juice. Also shut down any apps running in the background.

The SpareOne mobile phone is not for everyday chatting, and there's no e-mail or Web browsing. This phone is meant for emergencies - now, or up to 15 years hence. That's how long the included single AA battery (an ultra-long- lasting Energizer Ultimate Lithium L91) is estimated to stay charged if stored unused. Once turned on, you get about 10 hours of talk time. The battery is replaceable. The phone looks pretty much like a basic cellphone (though a bit longer, at 5.5-by-2 inches, but slim and featherweight)
