so i've recently purchased a property which has a stream flowing through it - not very big. maybe 18ft wide, currently 16 inches deep - though have no idea what its like in winter. it flows year round, and i have the land on both sides of the river for approx 200m. i also do not know what the flow is like - but it has no significant drop in height from entry to exit from the property.
Generating electricity from it was not on the agenda until after i bought the place, and am now attempting to determine if it would be a realistic proposition. I have no huge determination to generate electricity as am not in an off-grid situation, however think it might be funky and a bit of fun to do - if done right.
there a various micro-hydro videos on youtube - but generally involve having a reasonable drop in order to create the power necessary to generate sufficient electricity. i came across
- the hydrocat which is technically a boat, fixed with cable, floats on the surface, and has a turbine which rotates with water flow generating electricity. this seems ideal to me, as planning might be an issue in the area for something more permanent.
they have published an interesting pdf http://www.magix-website.com/mppo14/50/F77/F77D69F030A711E3A157F3635BB33A7A.pdf which has the various models and pricing too with expected electricity generation for respective water flow rates. i have no idea how this compares with other personal renewable sources of energy... the 'green' electricity company is airtricity - which charges approx 18c per kwh currently.
there is no building on the land - but i would ultimately hope to power a single home and associated outhouses for workshops / garage.
Does anyone have any thoughts on these? i am completely open to considering all other alternatives to this and would be grateful for any advice at all in relation to this topic as i am a complete novice
