Compressed-air energy storage
Compressed-air energy storage. A pressurized air tank used to start a diesel generator set in Paris Metro. Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. [1]

Sand dam
A sand dam is a reinforced concrete wall (or a similarly robust and impermeable weir) built 1–5 metres high across a seasonal sand river. When it rains the dam captures soil laden water behind it – the sand in the water sinks to the bottom, whilst the silt remains suspended in the water. Research on Kenyan dams shows that only 1 to 3% of
