Andy Lagzdins built and documented a pedal-powered air compressor to run the power tools in his motorcycle workshop.
Compressed air energy storage is a sustainable and resilient alternative to chemical batteries, with much longer life expectancy, lower life cycle costs, technical simplicity, and low maintenance.
Historical compressed air systems hold the key to the design of a low-tech, low-cost, robust, sustainable and relatively energy efficient energy storage medium.
Flushing the water closet wreaks ecological havoc, deprives agricultural soils of essential nutrients and makes food production dependent on fossil fuels.
What makes the car on air revolutionary is not that it runs on air but that it’s very small, light and slow.
