Global warming.
It wouldn’t be a problem if we all did our bit.
Walking along the cliff again from Borth to Aberystwyth last week I realised that a broken wall surrounding the point where a stream meets the sea must have been built to form a small dam. I wondered what the purpose of the dam was. I couldn’t see any signs of a water wheel which I thought it must have been built to serve. Looking on the web later because I was interested to find out the purpose or history of the large adjacent house I discovered that another passer by had spotted possible evidence of an old hydro-electric plant, http://www.geograph.org.uk/photo/23367
Maybe the houseowner should now restore it as farmer in nearby Dinas Mawddwy has done?

Dam, Wallog
Small dam across the stream by Wallog. Now broken through, it would originally have created a small reservoir behind. Remains of ironwork suggest it might have had early hydro-electric fittings?
