This entire website and all its content is an AI-generated theoretical framework created as an exploratory exercise to envision potential pathways to net-zero energy solutions. This is NOT a real, operational network, nor are there any actual plasma forest installations.
All technical specifications, protocols, and implementations described here are speculative interpretations of historical research by Tesla, Mallove, Moray, and others. This project represents hope and vision for sustainable energy futures, not existing technology or proven solutions.
No claims of working devices or energy generation are being made. This is a conceptual exploration and should be understood as such. Any real-world implementation would require extensive scientific validation, engineering development, and regulatory approval.

Understanding RF Propagation
Free Space Path Loss (FSPL)
The fundamental model for signal attenuation in ideal conditions. Signal power decreases with the square of distance due to the inverse square law of electromagnetic radiation.
Where d = distance in km, f = frequency in MHz
Two-Ray Ground Reflection Model
More accurate for terrestrial links where ground reflection creates multipath. Beyond the critical distance, path loss increases at 40 dB/decade instead of 20 dB/decade.
Used by VE2DBE Radio Mobile for terrain-aware propagation modeling
Fresnel Zone Clearance
Radio waves don't travel in a laser-thin line. The Fresnel zone is an ellipsoidal region where most signal energy propagates. Obstructions within this zone cause additional attenuation.
60% clearance of the first Fresnel zone is typically required for near-free-space propagation characteristics
Link Budget Analysis
The complete accounting of all gains and losses in a radio link. A positive fade margin indicates a viable link with headroom for atmospheric variations.
Essential for planning reliable mesh network node placement
