Though resurrecting the floating undershot water wheel would be easier, and would also provide power, with very little infrastructure required, except for anchor points on the bank. A lot simpler and probably much more efficient.

Infact water power is efficient compared to other farms like solar, wind so long as the flow is there.

I designed a simple but innovative microhydro device for low heads. In Southern India in Agricultural fields water is pumped by irrigation pumpsets in to storage tank (about 1 m height) and released at the bottom to the fields through small canal. After release from the tank the water flows by natural gravitation.

I devised a Microhydro device with Pelton wheel made from buckets used in rice mills for elevating rice. The Pelton wheel is attached to a bigger aluminium wheel (1 ft diameter through shaft and to a smaller diameter wheel attached to a low RPM Generator through V-belt). There is a diode to arrest the reverse flow of current. The buckets are made of hard plastic so that they won’t get rusted.

The whole set up is fixed on a frame. The system is placed at the outlet of the water tank so that the flow falls on the pelton wheel which in turn rotates the generator to give power. This power can be utilised to charge the batteries in parallel. Three 12 V batteries can be charged. The whole system costs about Rs 10,000(about US $ 210) in South India. The Unit can be fabricated at local workshops and mobile. It provides livelihood for people in rural areas in developing countries. Also the unit can be placed directly under Electric/Diesel pump sets so that the water (with force) from delivery pipe falls on the pelton wheel.

BUt perhaps someone else wrote on it & i just forgot about it

Whatever happened to that technology?
Also, I can’t find a third level of oars on that boat, so it looks like a bireme to me.
