ALTERNATIVE ENERGY FORUM - etc.

Think Death Valley California.😁

Ahhh well, that’s basically a natural rocket stove! At the stupid end of the hot spectrum 😂.

I see what you’re getting at, but, the exhaust in a rocket stove comes from combustion, which rapidly heats the air, causing a strong updraft due to gas expansion and high-temperature convection creating a significant pressure difference, driving airflow (with force) up the chimney.

I see a black plastic sheet heating air passively generating anywhere near the same effect. The air will warm gradually, creating a much weaker convection current. Without the extreme heat of combustion, the airflow speed and pressure difference will be low—nowhere near enough to meaningfully drive a turbine.

Even if vortex fins help guide the exhaust flow, the issue is that a cooler, passive convection system lack the energy to produce strong airflow. Rocket stoves on the other hand are very hot, and that’s what makes their exhaust forceful. I can’t visualise a solar-heated air achieving the same effect.

Watch some videos of Rocket stoves. There's quite a force coming out the top of the chimney. I imaging the same force, yet much cooler, is available at the input also.  Then the vortex creating fins make the exhaust spin. Maybe I'll draw it up with tinkercad 3D.

Rising and spinning. The ones I saw years ago had 200 foot chimneys.
Amplifier = yes

I guess this is a bad idea 😩
