EDM stands for Electrical Discharge Machining. It is a precision process of creating high voltage sparks to vaporize metal. It’s most commonly used for creating hardened alloy tooling needed for other manufacturing processes – alloys that are very difficult to machine with traditional cutting and milling methods.
Thermocouples are simple reliable devices that generate electricity from a difference in heat. They work exceedingly well as sensors to measure temperature at precise points.
Ever wonder how your “silent” phone ringer can be heard from across the room as it dances on the table top? Or why your iPhone’s screen button doesn’t press in when it’s powered off? didn’t notice that? …try it! Or how you can feel the racecar go off the track on your game controller? Haptics.

Free Piston Linear Generators could be the "missing link" our ancestors will trace back to the transition from fossil fuels to clean energy.
Nitinol is a shape-memory metal with amazing properties. While it may not be a "free energy" solution, its superelasticity is quite useful.
Cosmic rays are what we commonly call the bits of atoms that are blasted across the cosmos at darn near the speed of light. The vast majority of these are nuclei of hydrogen or helium atoms, so they’re positively charged, relatively massive, and highly energetic when traveling at that speed.
In Moonwalking with Einstein, Joshua Foer talks about his personal feats with memorization while covering a national memory competition event as a journalist – then goes on to win the competition himself the next year by using the techniques he learned. He shares the techniques in detail and dispels doubt and rumor in this entertaining book.
In book one of a four part series, author Nassim Tabel breaks down the things of chance in our lives and how our minds deal with it. If you're someone who frets over decisions and needs to decode every outcome, this book offers a different perspective and argues the idea of picking a direction and acting quickly.
Wax motors are little devices that utilize the unique properties of wax to push and pull things when its temperature changes. If you’re like most people, you’ve benefitted from wax motors – likely even have a few of them at home – and don’t even know they’re around.
