It can be programmed to go deeper.

@masara So all the research done with optical and electron microscopes, nuclear magnetic resonance, and magnetic resonance imaging was wasted because they could just have used an ohm meter? I don't think so. Dendrite growth in electrolyte has recently been discovered to be a later stage of the...

However, there have always been concerns over their fire safety – as after several charge and discharge cycles, potentially dangerous tiny lithium fibres, known as dendrites, can form on the carbon anodes. These fibres can short circuit the battery, causing it to overheat and catch fire. --...

Lithium cargo facing outright industry ban Posted on April 1, 2014 by Aimee Turner A worldwide cargo ban on transporting highly combustible lithium metal batteries on passenger aircraft could be imposed on airlines as early as next week, writes Aimée Turner. There was comprehensive testing of...

I should add that the search has turned into an embarrassing circus full of clowns in the media and printing press largess from the bankrupt United States. It is estimated that there is over 100 millions tons of garbage in the Pacific Gyre between Hawaii and the west coast of the US. The other...

The Kleptocracy of Malaysia is the world hub of counterfeit Li-ion battery manufacturing and shipping. If you understand how microscopic defects lead to dendrite growth and short circuiting (see the Dreamliner thread), you will understand my cynicism about the veracity of any documentation...

Ha, ha! Now the Malaysians will INVENT terrorists since they never had any. The cost to Malaysia of the plane going down due to terrorism is ZERO, while the cost due to incompetence in shipping dangerous cargo on their passenger airliner could reach a BILLION DOLLARS.

I believe it has to do with the limb of the Earth radio shadow effect. By triangulating the ping signals and determining when the signals reached some satellites but not others which had been receiving but had passed into the radio shadow, they could deduce the southerly direction. Once that...

jim hardy;4696320]Ptero- are those fumes debilitating ? Can they get into cockpit ? ~Hydrofluoric acid can dissolve glass. Hydrofluoric acid vapor is horrible. Among the worst. It can be carried by smoke but it is a clear, odorless gas. It attacks the mucous membranes - the eyes and the...

According to US-based Federal Aviation Administration, lithium-ion batteries carried in the cargo or baggage have been responsible for more than 140 incidents between March 1991 and February 17 this year, it was reported by Malaysiakini. Billie Vincent, the former head of security for the U.S...

Note that the descent of the UPS 747 was uneven due to "pitch control anomalies," similar to the 777 incident: A cargo on the main cargo deck had ignited at some point after departure. Less than three minutes after the first warning to the crew, the fire resulted in severe damage to flight...

I'm following a lead that there were 2000 lbs of lithium batteries on MH370. I believe that would be 3-4 pallets. Visitors to the Dreamliner thread will remember how impurities in the manufacturing process can lead to increased risk of shorting in new batteries. "Counterfeit batteries (i.e...

<<<Do you have a source for this? Release #13.FDX July 26, 2013 FedEx Pilots’ Union: Report on UPS Crash Highlights Need for New Regulations on Carriage of Lithium Batteries MEMPHIS, Tenn. — On September 3, 2010, our industry lost two fellow aviators when UPS Flight 6 crashed near...

Irving said the flight's disappearance had been compounded by "an engulfing fog of speculation, frequently reaching a tone of hysteria". "People are spooked. They want information that nobody is able to provide. We have come to expect quick enlightenment. That isn’t possible. We demand...

One problem is that many lithium-ion batteries today contain fluorine, which readily combines with hydrogen to make hydrofluoric acid (HF). In accidental battery fires, HF is noxious, dangerous to the touch, and an inhalation danger...
