Technology trials & tribulations
The Prospectory agenda (assuming we were ever formal enough to have such a thing) suffered a significant set back when Peter was diagnosed with Motor Neurone Disease in December 2017. Having said that, our combined interests in technology and psychology … Continue reading

Role of Hydrogen in Transport – A Seminar Report
The energy for the vast majority of transport, and certainly personal transport, still comes from burning fossil fuel in vehicles. Delivering that energy as electricity poses technological challenges with few solutions that promise a complete replacement for what we have … Continue reading
Natural energy storage
It’s good to be reminded every now and then how plants do energy storage over long time periods much more effectively than we ever can with batteries. The process is less efficient but the lengthy time shifting is invaluable from … Continue reading
1 Year domestic solar storage data
We have now had our 6kWh Wattstor solar battery (nicknamed ‘Bert’) for a full 12 months. (It actually holds 12kWh but only half of that is used by the system.) It was installed by Gwent Energy CIC. Previously, we simply … Continue reading

May 2016 to March 2017 Solar Storage Data
As the days get longer, our solar generation increases. March actually generated about the same as last September but the Wattstor battery control system is cautious about allowing the batteries to discharge beyond 70% or so until it’s confident there’s … Continue reading
Underground Energy Storage
The Glyn Rhonwy pumped storage scheme has apparently received the go-ahead, overcoming objections to any development like this in a National Park. It uses a disused slate quarry for the upper reservoir, which should make the overall development cheaper, and … Continue reading
May 2016 to Feb 2017 – Solar Storage Data
Spring is in sight and we have just done the analysis of February’s performance with our solar PV (4kW) plus Wattstor battery (6kWh) system. The longer days and the sun being higher in the sky have started to make a … Continue reading
May to December 2016 – Domestic Solar Battery Data
“‘Tis the year’s midnight, and it is the day’s, Lucy’s, who scarce seven hours herself unmasks; The sun is spent, and now his flasks Send forth light squibs, no constant rays;” So, how has Bert, our Wattstor solar battery, fared … Continue reading
May to November – our solar battery data
The latest update – 7 months with Bert our Wattstor battery (May to November). November here in Wales has been pretty murky until the last week. We also lose the sun over the hill behind the house at around 2:30pm … Continue reading
May-October – Our solar battery data
So, here’s our 6 month update of life with Bert our Wattstor battery (May to October). Every month we learn new things. As well as the shorter days, October has been rather misty and murky but still our 4 kW … Continue reading
