Motorcycle Gasifiers
Motorcycle gasifiers may not be the most practical transport, but a few have been converted over the years—a great YouTube video on gasifiers in USSR.

The Denver Zoo is committing to sustainability by harnessing the power of animal waste. To reduce its environmental footprint and increase its green credentials, the zoo plans to use 1.5 million pounds of animal droppings and other solid waste yearly in gasifier systems. Gasifier systems can convert animal waste into usable energy. The energy will power the zoo and its facilities. The Denver Zoo also plans to recycle 90% of the solid waste produced by visitors and employees. This includes paper, plastic, aluminium cans, glass bottles, and food scraps. Managing animal waste and other solid materials, the Denver Zoo is taking steps toward a more sustainable future.
