Small Scale Updraft Tower
The Solar Updraft Tower is a proven but still largely experimental way to generate electricity. The source of heat can be solar (requiring a heat collecting area) or chemical fuel (e.g. biomass combustion). Waste heat from other processes (such as lime making, biochar production, etc.) could be used. Below is a link collection of some research on small-scale updraft towers.
- CEBs for chimney (although CEBs might not be able to support a high chimney, and fired bricks may be needed)
- Vertical Shaft Brick Kiln - fired bricks for the chimney
- Kon-Tiki Kiln - waste heat can be used
