Lithium-Ion Batteries Emerge as Possible Culprit in Dreamliner Incidents
1/17/2013

Auxiliary power batteries onboard a Japan Airlines Dreamliner 787 caught fire at Boston's Logan Airport on January 7. The battery was taken back to the National Transportation Safety Board's Materials Laboratory in Washington for further examination.   (Source: NTSB)

Seems like the batteries are the culprit, but as of now no one knows why. They've x-rayed the batteries, put them through CT scans, disassembled them and checked the associated wiring bundles and battery management circuit boards. As of now, regulators have said that overcharging doesn't seem to be the issue, but we don't know much more than that. We'll have more coverage on this coming up.

Japen's agency essentially has said the same as the U.S. NTSB, to date, Cabe. No overvoltage. No overcharging, according to the reports I've seen.

Looking forward to reading your follow-up coverage on this, Chuck.

You have to wonder who in their right mind would get on the 787 after all this?

max take off weight of 787-9 is 251 metric tons (modification for long distanses 15700km), total force from engines 64.4tons

amazingly 787-3 (not in production) has near 170 tons weight and flight distance 5500km, total engine force 48 tons - look like very different plain, but with same design & engines.

Latest Analysis
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
The machine is claimed to be the largest and most powerful electric pipe-bender on the market, exerting nearly 500,000 lb-ft of torque.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
This consulting firm has put together a report detailing the growing biomimicry design field in the US and around the world, from naturally bacteria-repelling surfaces to keratin-inspired polymers.
Here's a list of engineering and tech jobs ranked by outlook, work environment, stress, and income.
