Well this lot for starters http://www.dailymail.co.uk/sciencete...nt-happen.html Apocalyptic predictions about the impact of climate change are 'overstated', according to a new study. Experts have found that the UN's worst case scenario, that the world could warm by up to 6°C (10.8°F) by 2100, is unlikely to happen. New calculations worked out the probable impact of greenhouse gases on global warming and found that more extreme scenarios will almost certainly not occur. They reduce the range of possible end-of-century outcomes by more than half, researchers said, including the best and worst case scenarios.

See https://wattsupwiththat.com/2017/10/...e-predictions/ I've just read the first three of those 'revelations'. Each one is a childlike misrepresentation. For example, the first (1990 IPCC report) fails to mention the margin of error. Or the most fundamental projection (+1C by 2025). It's not as if the report didn't contain enough errors elsewhere ;-) I have to accept that very few 'climate deniers' on this NG will read, much less accept, peer reviewed work by trained scientists.

Many (all) of the often reported forest fires are not due to climate change. For many hundred thousand years fire has been natures way of regenerating itself. More recently, in many hot dry areas the practice of grazing domestic animals, or wild populations of native animals, in woodlands has declined leading to a lot more dry materials to fuel a fire when it does break out. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

I'm a very long way out of touch Clive and my maths have always been suspect. However, my assumption is, for a domestic single phase supply, there will be a number of milliseconds where the voltage is insufficient to provide a charge. Now you can store energy in a capacitor or an inductor but these would need to be high capacity in view of the charge current needed. I doubt much of this current draw is going to be sinusoidal so probably identifiable with respect to conventional domestic loads. -- Tim Lamb |

The battery is 330 volts. |
