Electrical engineer David L. Jones explains why claims made on behalf of The Batteriser--a gadget promised to get up to 8x life out of alkaline batteries--are nonsense.
The Batteriser is a really neatly designed product (apart from the shorting issue), I love the miniturisation technology in it, and I’ll be buying some once it goes on sale to check out how they have done it. And yes, it can and certainly will work on some, perhaps many products and get some extra life out of it. But the 800% claims are demonstrably untrue, and unfortunately this is what every media outlet ran with. They took a blue sky marketing estimate and ran with it because it made a great story. There was no basic fact checking. All the electronics engineers who immediately questioned the claims were right in doing so, it’s trivial to prove there are issues with even the most basic of engineering due-diligence. There are just way too many downsides and unanswered questions on this product. I’ll guess we’ll have to wait and see until they start shipping so we can get one and actually test it.
Just get Eneloops, civilian.
It Betteridge! Jon Phillips reports on the Batteriser, a metal sleeve promising "up to" 8X more life from disposable batteries.
It’s essentially a voltage booster that sucks every last drop of useable energy from ostensibly spent batteries. So, instead of using just 20 percent of all the power hidden inside of your Duracells and Energizers, Batteriser makes effective use of the remaining 80 percent. Voltage boosters are nothing new, but Batteriser scales down the technology to the point where it can fit inside a stainless steel sleeve less than 0.1 mm thick. Roohparvar says the sleeves are thin enough to fit inside almost every battery compartment imaginable, and the combined package can extend battery life between 4.9x for devices like remote controls and 9.1x for various electronic toys.
Here's the published patent application, which is not a patent.
Red flag: Phillips writes that the creator proved he wasn't selling snake oil by demonstrating the gadget for him, but there's no description of independent testing. Did the guy just play with it in front of you? Who provided the batteries? What were the test controls? Boosting voltage at the expense of amperage and getting 800% more operational time, really? Turned down VC because the "money trail" led to battery companies, in favor of Indiegogo? Consumers with mountains of nearly-dead alkaline batteries want to know!
"Quacks and Nostrums" is a 20-minute film from 1959. We meet a woman who purchases a "South Seas" herbal tea with alleged powerful healing properties. The woman's son becomes concerned and visits the family doctor to ask him what he thinks. The doctor, who has all the time in the world to chat, recommends that he visit the local branch of the Food and Drug Administration to learn more about what the government is doing to crack down on snake-oil paddlers. He does, and a gentleman from the FDA invites him into his office for a chat, and he is shown a number of bizarre quack remedies confiscated by the FDA.
Unfortunately, the man's mother doesn't listen to her son's pleas to seek legitimate medical help and develops a serious gall bladder problem that is unaffected by the tea she bought from Alooka Ka'humana. I won't spoil the ending for you.

You are Not So Smart is hosted by David McRaney, a journalist and self-described psychology nerd. In each episode, David explores cognitive biases and delusions, and is often joined by a guest expert. David concludes each episode by eating a delicious cookie baked from a recipe sent in by a listener.
Where is the line between medicine and alternative medicine? Are Eastern medicine and Western medicine truly at odds, and if so, who is right and who is wrong? What harm is there in using complementary or integrative treatments in an effort to improve wellness?
In this episode we discuss alternative medicine with Tim Farley, creator and curator of What's The Harm, a website that tracks the harmful effects that result from seeking out alternative treatments and cures before or instead of seeking out science-based medicine. Tim also created the website Skeptical Software Tools, and he tweets at @krelnik.

Happy Read Comics in Public month! In honor of the world's fourth favorite made-up geek holiday (August 28th -- happy early birthday, Jack Kirby!) here are some picks to help you get started on your outdoor sequential art consuming skills. This time out, we've got something for the history buffs, something for the kids, something for the metal heads and, of course, something for the unemployed turtles.
The Hypo: The Melancholic Young Lincoln
By Noah Van Sciver
That’s short for “hypomania,” Lincoln’s self-prescribed melancholy, a lifelong battle with depression that hit like a ton of bricks in the young lawyer’s mid-20s. For those who have had some trouble accessing one of the most mythologized figures in American history (a category I'd imagine applies to most of us), Noah Van Sciver offers a pretty good place to start -- a young Lincoln moving to a new city, confused and awkward in love and life, given to bouts of darkness and moody poetry. It’s a short small snapshot of the future president’s life -- and it’s in this limited scope that the book finds its success, not beholden to the birth to death summations that often entrap graphic biographers. Instead, The Hypo's relatively limited scope afford the cartoonist the ability to approach the historical giant as a human, offering an empathetic examination of a troubled individual destined for greatness.
