Solomon Islands,Lao PDR, different locations in the USA are now developing technologies like:
- Gravity hydraulic machines (water wheels and Archimedes screws)
- Turbines (very low head turbines and hydrokinetic turbines),
- Advanced designs and
- Operation strategies for pumps as turbines (PATs)
.. to generate power from water(Hydro Review,IHA etc.).
Other countries are also looking for technologies to generate power from the low heads using a small amount of land.
