01 / What it is
A printed reference manual.
A book that collects descriptions of devices and systems discussed in the free-energy field — the kind of material usually spread across patents, newsletters, out-of-print pamphlets and forum threads.
Independent affiliate guide · Amazon
A reference volume that gathers the devices, patents and systems associated with the free-energy field — the source material behind the claims, collected in one place instead of scattered across old journals.

At a glance
01 / What it is
A book that collects descriptions of devices and systems discussed in the free-energy field — the kind of material usually spread across patents, newsletters, out-of-print pamphlets and forum threads.
02 / Who it suits
Bench hobbyists, armchair inventors, students of fringe engineering and collectors of technical ephemera — anyone who would rather read the original descriptions than a summary of them.
03 / Who should skip it
If you want a certified, step-by-step plan that produces unlimited power for your home, this is not that book. Nothing on this page claims that the designs described actually work.
Who picks it up
Free-energy literature has a very specific audience. If any of these sound like you, the manual is likely to earn its place on your desk.
01 / The patent archivist
Reading the original descriptions — with their diagrams, claims and quirks intact — beats a secondhand summary every time.
02 / The bench experimenter
You want a catalogue of designs to study first, so you can decide which ideas are even worth an evening at the workbench.
03 / The skeptic
Evaluating a claim properly means reading it as written, not as it arrives through a headline or a comment section.
04 / The energy historian
Why these movements appear, what they promise, and why they persist is a genuinely fascinating story — and this is part of the record.
Expectation setting
Honest framing matters more than hype on a page like this. Here is the plain version.
Projects in this field routinely involve mains voltage, high-current batteries, strong magnets and fast-moving machinery. Those are genuinely dangerous, and a book cannot make them safe. Keep experiments low-voltage and supervised, follow local electrical codes, and never assume a design outputs more energy than it takes in.
How to read it well
Skim for what each device claims to do, then look at the mechanism described beside it. The gap between the promise and the explanation is usually the most interesting part of the page.
Note the names, patents and years referenced. Cross-checking a single claim is usually one search away, and it tells you quickly how carefully the material was assembled.
Choose the simplest concept, sketch it on paper, and treat any experiment as a learning exercise — not as a power source for your home.

Before you buy
A printed book — a reference manual by D. A. Kelly that collects descriptions of free-energy devices and systems. It is reading material, not a kit, a course or a component set.
No, and this page makes no such claim. The manual documents designs and claims associated with the field. Whether any of them work is a separate question, and one you should evaluate critically. Nothing here is independently verified.
It helps but is not required. If you already know basic electrical terms, you will get more out of the descriptions — the terminology is part of what makes the material usable.
Format, page count, publisher and edition are shown on the Amazon listing for the specific edition on sale. Check those details on the listing before ordering, since they can change.
Any build you attempt is entirely at your own risk. Mains voltage, high-current batteries, magnets and rotating machinery can cause serious injury. Work with qualified supervision, follow electrical codes, and never assume a design produces more energy than it consumes.
