Heat Pump. The figures below are quite accurate. The thing is, though the solar more than covers it. Here is today's input and out from my system. The orange stripes are power being use and the blue power being generated. Note the very long orange 4 stripes is the hot water heater which has been off for a fortnight because we have been away. Normally, the hot water only requires about 30 minutes a day. Today is a mostly cloudy day Running a 2.5 kW split system air conditioner on heat costs about $0.25 to $0.40 per hour, or roughly $2.00 to $3.20 for an 8-hour day, based on an average electricity rate of $0.35 per kWh. [1, 2, 3] Cost Breakdown Hourly Cost: $0.25 – $0.40 per hour Daily Cost (8 hours): $2.00 – $3.20 per day Electrical Draw: Uses about 0.6 kW to 0.8 kW of input power per hour (the 2.5 kW rating is the thermal heating output, not the electricity consumed). [1, 2, 3]

A husband walks into Victoria’s Secret to buy his wife a sheer nightgown. The clerk shows him several options ranging from $250 to $500 - the more sheer, the higher the price. He picks the sheerest one for $500 and heads home. He gives it to his wife and asks her to go upstairs, try it on, and model it for him. Upstairs, his wife thinks, "It's so sheer it might as well be nothing! I'll just model naked, return it tomorrow, and keep the $500 refund for myself." She appears naked on the balcony and strikes a pose. The husband looks up and says, "Good grief! For $500, you'd think they'd at least iron it!" He didn't see the punch coming and should be able to see out of at least one eye by the weekend.

What sort of heater do you use, and how long can you run it for on a cold day?

That's NOT what showed up on my checking of the source. PLEASE be More careful. My server just contacted me to change a Password urgently . Nev

It's a Facebook meme warning Americans what they could be in for.

According to whom? American Primer Weekly? It's highly UNLIKELY. Nev

Your future awaits.

There are Many different ways to win at chess and there are Many checkmate Positions. Can't you also have a stalemate?. .The Rules are the Way the Various Pieces are Permitted to Move. Nev

Trump is excellent at Ignoring advice. He was brought up with the attitude of NEVER being wrong. Menadue's Blog is" Pearls & Irritations". Always worth a read. Nev

But Peter, that's from experts. As every one of Trump's administration picks proves, being an actual expert in something automatically disqualifies your opinion.

I suppose an analogy might be chess. The rules of chess are known (coded) but the process by which each game reaches a conclusion is unknown (the AI model) even though the conclusion is known - it's going to be a win or a draw ( a correct prediction).

Like any other program. The programmer decides what the rules are that govern how the state of the ‘neurons’ in the network should change depending on the outcome of a trial and implements those rules in a programming language like C++ or Python. It’s just a feedback loop. You start by assigning random values, say between 1 and 10 to a node in the network and run a trial that gets it to predict an outcome. If the prediction is correct that node’s value is increased by some amount. If it guesses wrong the value is decreased so its importance in the network is reduced because its opinion is less ‘reliable’. Although I’ve said ‘a’ node, it’s applied to all nodes in the network. That’s the basic theory as I understand it. If you have billions of nodes being ‘trained’ the network may eventually start to seem to produce intelligent answers to questions although nobody really knows exactly what its internal state of ‘mind’ is because although the rules of the game have been coded the process of learning’ is fundamentally random trial and error.

Just ask AI. https://www.phpcluster.com/how-to-write-an-algorithm/

Why expect to find the answer HERE? We are mere Mortals. Nev

How do you create a "formally coded algorith"? That is my question.

Electric motors and converters still release heat as does anything that makes the electricity to power them. Would be interesting to see how much a WTG releases with gearboxes, muliple electric motors converters and hydraulic systems/ MWh.

Do you guys really think the other partys are tied to billionaires?

In spite of all the stuff going on so far, It's gone beyond just a case of 'What has tRump done now?'.... Quoted from Pearls & Wisdom: "a group of 36 senior neurologists, forensic psychiatrists, general psychiatrists and mental health professionals experienced in the diagnosis of cognitive disorders and evaluation of dangerousness, who had signed an earlier statement in 2024, issued an update on 30 April of this year. They cited examples of Trump’s “marked deterioration in cognitive functioning, evidenced by disorganised and tangential speech, rambling digressions, factual confusions, unexplained sudden changes of course in strategic matters, both national and international, episodes of apparent somnolence during crucial public proceeding. Grandiose and delusional beliefs, including assertions of infallibility…claims that his decision-making authority is unlimited – with no need to consider domestic and international laws and constrained only by his ‘own morality’. Severely impaired judgment and impulse control…Significant loss of self-control (disinhibition) and getting stuck on the same thoughts or actions, unable to let go or move on (perseveration), including seemingly compulsive, manic-like late-night communications – e.g., 150 social media posts in one night.” They conclude: “it is our expert opinion that Donald J. Trump is mentally unfit to be the President of the United States, and that steps to remove him from office must be undertaken with the greatest urgency”. And this bloke has 24/7/365 access to instantly start launching numerous preplanned nuclear ATTACKS. https://johnmenadue.com/post/2026/07/for-president-trump-starting-nuclear-war-as-easy-as-sending-a-tweet/

How do you writ up the insurance claim?

A Random thought...

I hope he hasn't fallen off his bike..... err, trike.

Yes because I did the rational thing and installed solar.

Haven’t seen OT on here for a while. Is he ok?

My understanding is that the neural network uses formally coded algorithms to alter its internal weighting parameters based on whether the model has made a successful prediction or not. If the neural network is big enough and the data it is being trained on is extensive enough its predictions become more accurate to the point where the AI model seems intelligent. Jerry can probably explain it better than I can.
