August 02, 2024 EEVblog 1633 Part 2 – WAVJA Patent, 300kW Solar Balls?
The WAVJA Photon Energy System is supposed to generate up to 60x the output of regular solar panels using balls made of magical patented woo-woo material.
A 60mm ball can generate 300kW in one second!
Let’s bust that claim by looking at the Patent in this Part 2 video.

01:18 – The patent: Reflecting light, where have we seen this before?
02:47 – It uses NMC?
04:03 – This sucker can power an EV
05:05 – The patent is just scientific word salad…
06:23 – “Stimulation Current” of 40Ah, HUH?
07:52 – It’s not Over Unity, but it’s totally Over-Unity
08:42 – 300kW Balls!
10:06 – 3D Printed using WHAT?
11:34 – How is it not an Integrating Sphere? And how does the energy get out?
15:58 – 100MW is a very conserative estimate!
17:39 – Isn’t patenting over-unity not allowed?
18:37 – A 60mm sphere can generate 300kW of electricity in ONE SECOND!
19:24 – Tested with a laser power meter? HUH?
20:33 – It’s got AI, trust me bro.
21:02 – UNLIMITED POWER! and transparent mirrors…
23:21 – Where is all this in the demo?
24:31 – Why do they have half balls?

00:00 – WAVJA Photon Energy System on Hack-a-Day
01:51 – This looks totally legit, so I BUILT MY OWN! The Photon Irradiance Solar System
04:15 – My balls work in near darkness! And produce 5 TIMES the power as WAVJA!
05:43 – What’s that you can smell?
06:52 – It’s got AI?
06:31 – Let’s watch the video and the claims made…
07:16 – Does it generate or absorb luminosity? It’s a tad confusing…
08:10 – 30 times smaller and 7.5x the output of solar panels!
08:57 – Capturing solar power is all about the Capture Area, dummy!
09:44 – It captures light and then WHAT?
10:43 – It’s Over-Unity BS!
11:39 – It’s got storage? 24 hour operation !
12:59 – Their test setup and “power meter” results are demonstable BS!
16:12 – Roughly 0.1W per ball, SO revolutionary!
16:25 – The “charge” just comes from a commercial power bank, LOL! They have NOTHING!
16:25 – Only 3000 hours to charge your Electric Truck battery pack
17:05 – It gets MORE RIDICULOUS! Flying cars, shipping container drones, electric trucks!
18:47 – The Patent & the Founders
19:59 – Where does the light go? I’m confused…
20:41 – Conclusion
21:57 – I’m GIVING AWAY my P.I.S.S Technology!

July 20, 2024 EEVblog 1630 – Solar Panels for Water Pre-Heating?
Is it worthwhile to run water through your rooftop solar panels to cool them down while pre-heating your hot water? Or maybe heating your pool? Also solar air and water heaters. As always, YMMV, but this is why I didn’t do it.
