Danny Kerr: TeslaPyramids

---

Pyramid researcher. Author of the TeslaPyramids theory.

Danny Kerr, from Niagara Falls, Canada, has spent the past decade researching how the pyramids of Egypt might have worked as machines. Niagara Falls is where Nikola Tesla's alternating current was first used to harness the falls for power, and Danny drew his inspiration from both the falls and Tesla. He wrote the first version of his Great Pyramid concept, "Fire In The Middle," in 2015 and revised it in 2016. He then visited Egypt to see the chambers and passages of the Great Pyramid for himself. After that visit he revised the concept again and launched teslapyramids.com in October 2016. That same month he started posting as @TeslaPyramids on X.

On X he sums up his work in two lines: he "published the original thermoacoustic pyramid concept in 2016" and "discovered the volume of the Great Pyramid equals the volume of all other pyramids at Giza." For years he shared his work mainly on Facebook, where Tesla Pyramids grew to about 20,000 followers, and on teslapyramids.com. He has also been interviewed by Al Jazeera about his work: he appears in "What was so scary about Tesla's ideas?", a 2022 episode of Decoded, the Al Jazeera documentary series presented by Egyptian actor Amr Waked. In it he explains how John Cadman's water-hammer work led him to the thermoacoustic idea, and compares the Great Pyramid with Tesla's Wardenclyffe Tower.

He developed his ideas alongside two friends, author and engineer Doug Keenan and model-builder John Cadman. The three called themselves "The Power Trio." In 2017 Danny joined Doug on the Den of Lore podcast for EP. 029, "The Big Pyramid Machine," and John joined them both for EP. 034, "Hard Pyramid Science," to talk about the pyramid as a machine.

Machines first, tombs second. Danny's starting point is that the Giza pyramids were built to do a job. He looks at their shapes, materials and wear marks first as working parts, and treats the tomb idea as secondary.

Water is the key. In plain words, the theory says the pyramids were giant, slow-pulsing water machines:

• Pumping. Water from the ground beneath the plateau is pushed upward by water hammer, the same pressure "thump" a ram pump uses. The passages under the Great Pyramid act as the pump. This part builds on John Cadman's working models.
• Resonance. The chambers and passages are sized to ring like a tuned instrument. Heat turns into sound (thermoacoustics), and the whole site pulses together at about once per second.
• Mist. The quartz-rich Aswan granite in the King's Chamber and around the pyramids vibrates at ultrasonic frequencies. Like an ultrasonic humidifier, it turns the lifted water into mist that returns moisture to the land.

Where it started. The 2015–2016 version compared the Great Pyramid to Nikola Tesla's Wardenclyffe Tower, a wireless power station, which is where the name TeslaPyramids comes from. Over the years the work moved from electricity towards water: from a "thermoacoustic pulsejet" in 2016, to nutrient-rich mist for greening the desert in 2025, to the current TRP (Thermoacoustic Regenerative Pulsejet) water-pumping model in 2026. Danny has been clear throughout that there is no "free energy" involved.

Testable, not mystical. The current model uses published dimensions and standard physics. It names the measurements and lab tests that would prove it right or wrong.

• "The model stands or falls on those numbers and the outcomes of the listed tests." (TRP paper, X, Oct 2026)

• 2015: Writes the first version of his Great Pyramid concept, "Fire In The Middle," comparing the pyramid to Tesla's Wardenclyffe Tower.
• 2016: Revises the concept. After visiting Egypt and seeing the granite blocks in the Ascending Passage in person, he revises it again.
• Oct 6, 2016: Publishes "The Thermoelectric Thermoacoustic Pulsejet Pyramid of Khufu," the first post on teslapyramids.com. The Wayback Machine first saved the site on Oct 15, 2016.

Feb 20, 2022: Appears in "What was so scary about Tesla's ideas?", an episode of Al Jazeera's Decoded documentary series presented by Amr Waked.

• 2016–2025: Keeps revising teslapyramids.com ("in a constant state of revision"). Additions include the finding that the Great Pyramid's volume equals the combined volume of all the other pyramids at Giza (98.7% by his figures, possibly 99.5% or more).
• Aug 20, 2025: Posts "Nutrient-Rich Mist Generation from Egypt's Pyramids" on X.
• Apr 2026: Loses his best friend and collaborator, Doug Keenan.
• Oct 26, 2026: Posts "The Great Pyramid Complex as a Water-Pumping Steam-Flash Thermoacoustic Network," the current state of the TRP model.

Danny's work stands on the shoulders of friends and fellow researchers:

• Doug Keenan: Cycles of the Pyramids. Engineer, author and Danny's best friend (1962–2026).
• John Cadman: The Great Pyramid's Hydraulic Pulse Generator. Builder of working models of the subterranean pump.
• William Armand Sosa: The Dendera Light. Known for recreating a working Dendera light.
