What is it about mechanical clocks? Maybe it’s the gears, or the soft tick-tocking that they make? Or maybe it’s the pursuit of implausible mechanical perfection. Combine mechanical clocks with “free” energy harvested from daily temperature and pressure variation, and we’re hooked.
Both the Beverly Clock, built by Arthur Beverly in 1864, and the Atmos series of clocks built between 1929 and 1939, run exclusively on the expansion and contraction of a volume of air (Beverly) or ethyl chloride (Atmos) over the day to wind up the clock via a ratchet. The Beverly Clock was apparently a one-off, and it’s still running today. And with over 500,000 Atmos clocks produced, there must be some out there.
Although we had never heard of it, this basic idea is really old. Clicking through Wikipedia (like you do!) got us to Cox’s Timepiece, which is powered by the movement of 68 kg of mecury under atmospheric pressure. It is currently not running, but housed in the Victoria and Albert Museum in London. Even older is a clock that we couldn’t find any info on that dates from 1620, invented by Cornelius Drebbel. Anyone know anything?
We’ve had energy harvesting on our mind lately, and the article on the Beverly Clock says that it gets 31 μWh over a day when the temperature swings by 3.3 °C. Put into microcontroller perspective, this is 0.39 μA at 3.3 V, so you’ll have to be pretty careful about your sleep modes, and an LED is out of the question. How amazing is it, then, that this can power a mechanical clock?
Thanks [Luke], [hex4def6], and [Wallace Owen] for tipping us off to these in the comment section!
Spend enough time on YouTube, and you’ll eventually find yourself in one of the many dark corners hiding within it. No, I’m not talking about the comments. In this case, I mean the many videos dedicated to free energy, overunity devices, perpetual motion machines, or anything else that violates the laws of thermodynamics by trying to get out more energy than is put in. The human race has been reaching for impossible dreams of perpetual motion and free energy for just about all of recorded history. Now it’s convenient to find them all in one place.
Browsing the tubes, it’s easy to break free energy videos down into two major groups: enthusiasts and scammers. Catching a scammer is easy – they’re looking for money. Somewhere in the video or description will be a link to a website with more information. Eventually that will lead you to a place where the scammer attempts to part you and your hard-earned money.
Names like John Searl, Muammer Yildiz, and M. T. Keshe go here. Searl especially deserves note because he’s been at it for decades. Supposedly, his “Searl Effect Generator” SEG has been built several times, but the prototypes generate so much power they create their own anti-gravity field and fly off into space. Obviously this man and his staff need your money to continue their work. Scammers deserve disdain and public shaming. These are the folks who know their “discoveries” are nothing more than snake oil.
On the other side of the coin lie the enthusiasts. These are the backyard tinkerers, the ones who put down their computers, pick up their tools, and try to build something. Sounds a lot like the average Hackaday reader, doesn’t it? I have to admit I went into this article with the same disdain for the enthusiasts that I have for the scammers, possibly even more. In some cases, these are the folks who truly believe they can have a chance to violate the laws of thermodynamics. Inevitably these folks fail to build free energy generators, overunity devices, or whatever their pursuit is, but they all do seem to learn something in the process. A lot can be said about the builds themselves. Some of these are awesome devices. Even if they don’t work for their intended purpose, they are great demonstrations of magnetism or chemistry. This is where I had a change of heart. If someone wants to spend their time working on an impossible hack, then more power to them. I may not think they have any chance of success, but at the very least, they’ll learn how to build.

Bang & Olufsen have made some pretty amazing equipment for a long, long time. That last part can become a problem. [Oliver] found the electrolytic caps on his Beomaster 2400 were causing problems. He completely recapped the unit, all the electrolytics anyway, and the pictures of the process are nothing short of eye-candy.
The closure of the Bacman forums marks the end of an era. For years this has been among the top (okay, it’s definitely been the top one but we don’t want to start a flamewar) sites for handheld and console modding. Here’s just one random example of the many projects we covered from that community (note that main link is now sadly 404). The closure message cites the near-absolute death of modding. We haven’t thought about it much, but these mods were futuristic. Then smartphones.
Fans of How It’s Made and 3D printing will want to tune in on April 30th at 9pm EST. The show does a fantastic job of showing off the amazing story behind how all the stuff in our lives comes to be visited LulzBot in Loveland, Colorado for a segment on the manufacturing process of a 3D printer.
We’re not sure why we didn’t lead with this: All celebrate, for humanity is saved! The secret behind getting something out of nothing has been discovered. This reactionless generator has been tested at efficiencies as high as 250%. We’re working on a way to bottle all that extra juice and sell it at outrageous prices.
The thing about free energy is that you become dependent on it. What if the laws of physics return from vacation and the thing stops working? Then you have a robot apocalypse with all kinds of hidden messages and puzzles in it.
In her new element-14 video [Jeri Ellsworth] explains some concepts about “free to you” energy and features the LTC3109EUF, an Auto-polarity, Ultra low Voltage Step-Up Converter and Power Manager, along with the LTC3588EMSE a Piezoelectric Energy Harvesting Power Supply.
Using the LTC3109EUF she is able to power a modified Nintendo Entertainment System, and LCD using a small generator and an exercise bike. The LTC3588EMSE is wired up to piezo’s in different applications including being squashed, vibrated, and temperature difference to power low current devices.
All this and a totally 80’s theme, so poof up your hair, get your spiked dog collar, and find those neon green shades because this is a fun and informative video available on element-14.
Reader [Hjhndr] ran across an interesting set of tests and wanted to know if they’re brilliant or just a load of bull. We’re not making the call on that, but the tests on a Steorn Orb motor replica are worth looking at.Keep in mind, people used to think the earth was flat and scientists of the time would have sworn up and down that’s the way things were.
The Steorn Orbo is a motor that generates more power than is put into it. At least according to Steorn Limited that’s what it does. An independent panel of scientists said otherwise a few years back but that didn’t stop the company from showing off the concept a few more times, most recently a showing in Dublin ended this month.
So anyway, [Jean-Louis Naudin] took what he saw from those demonstrations and built a replica. He’s made several papers about the principle as well as his testing available online. There’s a lot of math, a little bit of smoke and mirrors, and several videos. Take a look and let us know what you think in the comments.
