Home Forums General Discussion Off Grid, but keeping all mod cons??? Re: Off Grid, but keeping all mod cons???


Slightly off topic,.. but I’ve been reading up on this again today,…

On the land is a small natural spring,.. really only a trickle of water, maybe 5 litres per minute, so I had discarded the notion of micro hydro generation. There is however nearly 40 mtrs of a fall from the top of the site to the bottom of the field (its on the edge of the valley). All the calculations are factoring flow & head,… can a 40mtr head realistically make up for a tiny flow rate or is there a point in more extreme cases like this where the maths simply doesn’t correspond to the real world very closely?
