Where Did All The Watts Go? | Big Mess o' Wires
The comments dig into some of how to understand power ratings on power supplies. Having done similar head-scratching when speccing the 240A 5V supply for Play the Tree, this is likely to be a handy refresher in future.

In doing so, the film is both a chronicle of his remarkable life and a robust reminder that genius is not confined to the places where it is most lavishly rewarded and popularly celebrated.

Crazy maths makes nonsense of Irish climate change policy
'John FitzGerald on madness of Ireland burning peat for electricity:

'the current subsidy per job involved is at least €100,000 a year. The Bord na Móna annual report indicates that, in the year 2016/2017, its workers’ average pay was €50,000. In other words, the subsidy per job is around twice what the workers involved actually earn.

If the peat-fired power stations were closed tomorrow, and the workers involved continued to be employed on their current wages, subsidising these jobs would only cost €50 million, not €100 million. Electricity consumers would pay less to subsidise these jobs, and Ireland’s greenhouse gas emissions would fall substantially as a result of discontinuing this polluting fuel use.'

We should plan for closure by 2020 of peat-fired electricity generation:

–greatly benefit environment;
–save electricity consumers money;
–protect livelihoods.
