PCB for wireless power transmission

Open, betrayal-proof space-based solar power infrastructure. Energy as a commons, not a commodity. No backdoors. No meters. No masters.

A solar-fed room that charges everything: panel to battery to safe infrared beam. Wearables trickle-charge from across the room forever; laptops take USB-C from the same banks. Harvest and storage are off-the-shelf today. Open design, CC0, no patent. A gift to all of humanity.

Wireless DC power transfer system for emergency mobile charging using battery — Hardware prototype + LTspice simulation

El proyecto consiste en el diseño y análisis de un stent coronario inteligente, que integra un sensor capacitivo y un sistema de comunicación inalámbrica sin batería. Su viabilidad técnica se evalúa mediante cálculos matemáticos.
