EVSE questions

A major player in the EVSE market has kindly consented to provide some technical training for the electrical installation tutors at a training centre where I often tutor part-time. I imagine it is not entirely motivated by altruistic considerations but at least it gives an opportunity for the tutors and myself to get some kind of grasp on the various products on offer and where this particular manufacturer sees the direction of travel for EVSE. I am already aware that the company is moving away from products that rely on the installation of earth electrodes in PME situations and are placing considerable focus on load management. Is there any particular question that you would ask them given the opportunity?

    So Jon, Steward, you are saying that it wasn't over 30°C for a week in the Arctic circle this year and that the Artic ocean has had decreasing ice cover every year.

    The problem is that the excess heat going into the atmosphere is resulting largely in warmer seas and melting ice. The actual temperature rise is very modest - for the moment.


    It was over 30°C in the Artic circle this year as it has often been in the past. Nothing unusual, the area has permenant sun in summer time. (It also often under -30°C in winter)

    Why is there a need to 'hype' normal weather? Is it beacause there is no real evidence for AGW. There is plenty of evidence that the Earth is naturally warming since the last Ice Age. Arctic ice cover is also slowly decreasing for the same reason. It is interesting that Antarctic ice is stable to increasing.
