Eco holiday In Brecon Beacon 2

Holiday home in Beacon Beacon is really beautiful. Apart from the wood burner that gave the heating to the compound we found another interesting feature. A renewable energy source.  A micro turbine housed in a small hut that our landlord Chris described as his pet project. It's a micro hydro power project generating 5 KW when full throttle.

Chris found a water source on top of the small hill. It's about 40 m drop to below. He put a large pipe and directed the water stream down to the small turbine unit.

In full throttle unit would generate 5 kW per hour. For 24 hours this would generate 120 KWh of electricity. Chris claims this is enough for his farms  daily needs. Any extra electricity generated would be feed back to the main grid. Specially late night and mid day when they don't use much energy.  Our children were very interested to see this mini hydro power generating unit. 
Water from the turbine unit released to this small stream.
How this works:
I took this explanation from the website quoted below.
"Micro hydro power is the small-scale harnessing of energy from falling water. Hydraulic power can be captured wherever a flow of water falls. The vertical fall of water, known as the “head”, is essential for hydropower generation (fast-flowing water on its own does not contain sufficient energy for useful power production). Hence, two quantities are required for production of hydropower: a Flow Rate of water and a Head. The capacity of a micro hydro power plant is usually between 20 and 500 kW."

Invest in micro hydro power plants
