Tech Guru Bill Joy Unveils Battery to Challenge Lithium-Ion

  Tech Guru Bill Joy Unveils Battery to Challenge Lithium-Ion Elon Musk isn’t the only visionary betting that the world will soon be reliant on batteries. Bill Joy, the Silicon Valley guru and Sun Microsystems Inc. co-founder, also envisions such dependence. On Thursday, Joy and Ionic Materials unveiled a solid-state alkaline battery at the Rocky Mountain Institute’s Energy Innovation Summit in Basalt, Colorado, that he says is safer and cheaper than the industry leader, lithium-ion. The appeal of alkaline: it could cost a tiny fraction of existing battery technologies and could be safer in delicate settings, such as aboard airplanes.

However, a research team in China has developed a new type of flexible battery that doesn't require dangerous chemicals. And the researchers discovered that the nanotube batteries might have an additional unforeseen use.

The batteries need to be flexible and remain functional while being bent or twisted, and ideally, they'll be absent of harmful chemicals. So far, batteries developed for these uses don't meet that latter requirement and instead pack on extra material to keep the chemicals from leaking and coming in contact with human tissue. But that often makes them bulky and rigid. However, a research team in China has developed a new type of flexible battery that doesn't require dangerous chemicals.

Recaptured polygamous sect leader's fraud trial delayed

  Recaptured polygamous sect leader's fraud trial delayed The recaptured leader of a polygamous sect accused of running a Utah and Arizona food stamp fraud scheme has won a one-month trial delay so lawyers can try to determine if he suffered memory loss or brain damage in two late 1990s accidents. U.S. District Judge Ted Stewart approved an Oct. 23 trial date for Lyle Jeffs, pushing it back from Sept. 18.Jeffs was arrested in February 2016 but became a fugitive after he slipped of an ankle monitoring device in in June of that year.He was caught in South Dakota on June 14 after pawn shop workers spotted him and called police.

Chinese researchers developed two types of flexible batteries that run on saline or salty water solution instead of lithium-ion electrolytes. Simply put, the newly engineered batteries are powered by a salt water solution that is biologically compatible.

However, a research team in China has developed a new type of flexible battery that doesn't require dangerous chemicals. The research team created two versions -- a belt-shaped model and a nanotube.

Instead of packing electrolytes that are corrosive or toxic, the team used sodium-based chemicals like sodium sulfate, which was once used as a laxative, as well as saline and a solution used for cell culture. While it's still preferable that those solutions don't leak out of the batteries and onto or inside of a human, if they do, it wouldn't pose the same risks that other batteries' chemicals do. Because excessive leakage-prevention measures — and therefore, added materials — aren't required, the battery can easily maintain flexibility.

The research team created two versions — a belt-shaped model and a nanotube. The sodium sulfate electrolyte worked best of the three solutions tested and its function held up against similarly-sized lithium-ion batteries currently used in wearables. And the performance of the belt-shaped version wasn't impacted even after it was bent 100 times at different angles.

Elon Musk teases research on a big battery breakthrough

  Elon Musk teases research on a big battery breakthrough It's no secret that Tesla likes to keep an open mind when it comes to exploring, researching and testing new battery technologies. In an effort to remain on the vanguard of any battery technology advancements, you might recall that Tesla inked a 5-year contract with reputed battery researcher Jeff Dahn and his team of researchers back in June of 2015. Dahn, it’s worth noting, is largely considered to be one of the world’s most prominent and influential experts on lithium-ion battery technology.

Body fluids could drive these salt -powered batteries in the future. But that often makes them bulky and rigid. However, a research team in China has developed a new type of flexible battery that doesn't require dangerous chemicals.

That these batteries can function off of sodium-based liquids means that in the future these devices might be able to run off of body fluids like sweat. And the researchers discovered that the nanotube batteries might have an additional unforeseen use. After observing that the nanotubes were accelerating the conversion of dissolved oxygen into hydroxide ions, which isn't great for battery power, they realized that this could be a feature if the devices were used in a slightly different way.

"We can implant these fiber-shaped electrodes into the human body to consume essential oxygen, especially for areas that are difficult for injectable drugs to reach," researcher Yonggang Wang said in a statement. "Deoxygenation might even wipe out cancerous cells or pathogenic bacteria since they are very sensitive to changes in living environment pH. Of course, this is hypothetical right now, but we hope to investigate further with biologists and medical scientists."

The work was published this week in the journal Chem.

Super fast-falling snowstorms may rage on Mars at night .
New climate models show that Martian clouds may create strong windsThe idea that snow falls on Mars isn’t a new concept. NASA’s Phoenix lander, which touched down on the Martian surface in 2008, was the first to measure snow particles falling from clouds above the planet. But at the time, scientists thought that this snow fell incredibly slowly, taking several hours to descend just one mile. But the new models, detailed in a new study in Nature Geoscience, suggest the snow could be falling much faster in some nighttime areas — taking just five to 10 minutes to drop a mile.
