Ionospheric Heater: “Powerful HF transmitter (2.8 to 10 MHz) that induces controlled temporary modification to the electron temperature at desired altitude”.
What does that mean?
Heater antenna arrays pump electricity from the ground into space. This artificial electrical alteration of our ionosphere creates many different effects. Scientists doing these experiments do so without any oversight. These experiments are highly controversial and likely are affecting more than just our atmosphere, they may be affecting your mood.
