Pocket Hydro
Pocket Hydro - A Mini Power Plant for Decentralized Electric Power
|
Aim is the provision of affordable electric lighting throughthe use of local water energy in remote rural areas.
|
 |
Concept
| A hand-wide stream suffices as source of energy for lighting and small appliances. The cost of turbine and generator are lower than for solar cells, also no battery is required. Installation and operation are simple, so the equipment can be sold "over the counter". |  |
Principles
Key Data
- Prerequisite is access to a stream with ~ 1 liter / second; at a slope of <2 m
- Current output sufices el. lighting, cell phone , radio [4 - 10 W]
- Optional upgrade with battery powers a TV [100-250 Wh / day]
- Complete selling price including lamps : USD 50 (targeted)
- Lifetime > 5 years ⇒ lighting costs / household <1 USD / month
Affordability (<50 USD):
- Long service life of turbine, generator and LED lamps
- Reduced cable length from the turbine to the house
- Basic supply without battery (hardly any wear / environmental impact)
- Minimized manufacturing costs by use of injection molded plastics
"Over the Counter" Product
Easy and understandable, suitable for use in remote regions:
- Private operation, so no user associations required
- Non-hazardous voltages - safe handling by laymen
- Robust , simple, portable, modular (repairable, upgradeable)
- Simple water-supply, -management and -filtering due to the small amounts required
Adapted to Local Needs
- Minimized requirements allow the utilisation of even small potentials; 1 l/s at 2 meters is quite often available
- The diversion of water to the house saves connection cable
- Easy installation and operation allow the direct sales
Time Horizon
Completion of a prototype by mid-2014 , with the following characteristics:
- Minimum of 50 % efficiency (total) in 0,5 - 1 l / s of water @ 2 m
- Design of complete system includes lights, cables , switches , pipes, filters , ...
- Field tests of the first small series from 2015
