1. CW? wot that? 2. Not sure why ac mentioned. When charging cap banks as an alternative to batteries, There should be no ac component. Like electrolytics, they dont like it. 3. Super cap banks used in hybrid vehicles use dynamic balancing, which from the literature, appears to be op-amp based, (one op-amp per cell, I think) but perhaps made from discrete components. Exact details are hard to come by, being commercially sensitive.

In my experience, key-specific problems are the result of local breakdown of the multi-layer contact membrane beneath the keys. Tough.

Apple cider, vinegar, and honey is a time-honoured folk remedy for arthritis, with some medical justification. The search parameters "vinegar honey arthritis" reveals much.

Same problems in the UK, and the cost to Londoners of their next Olympics, astronomical (Except property developers who as usual will make a killing).

This is my simplistic and "kitchen table" view, and works so-far: No. Not voltage doubling, entirely different. Each cap of the same spec in a stack will hold a similar charge, but will attain a slightly different voltage. They are sensitive to over-voltage charging, reducing lifetime. Either under-charge the stack so that no individual cap exceeds its rating, or put a bleed resistor across each cap to allow equalisation. This will cause leakage, but you can choose higher or lower resistance according to charging power, and duty cycle between charge/discharge. Dynamic balancing requires an op-amp across each cell, but it adds to power drain, cost, and reliability. Hyper, super, ultra, whatever are just trade names, and technological variations are appearing all the time. All require the same care.

In a nutshell. 'nuf said. No mention of pop stars and filmstars, they are in the same league. Objectors should vote with their wallets, perhaps by not supporting pop culture or going to the cinema for a start

Question aked, question (briefly) answered. Response?

Interesting how infrequently some of the "luminaries" contribute to the forums. I suppose there is something to be said for quality rather than quantity, and low profile policing.

I looked. It is a drug company doing research into pain relief. What did I miss?

So the 2bn. that stay on earth could all be farmers and grow the food that we put in the food parcels we send to mars and the moon? I'll vote to stay on earth, then, could become quite nice......

I second that.

Yes, rather worrying I picked on that with a gut reaction! Perhaps I should steer clear of your project implicit, I might find I am not who I think I am. What the hell, too old to change now. I know what you intended to mean, (Ithink) and agree. Just could not resist it. No offence meant.

Can't think of a good reason to go for any one particular population level. As long as it is less than the present, 4bn. is as good as any. Couple of observations on previous comments that may sound flippant, but are not meant to be: 1. Quality over quantity? (YT..): Yes, of course; higher quality dustmen, general domestics, shop assistants, auto mechanics, etc. Anything to maintain the comfort and lifestyle of the superior classes! 2. Rather than just a question of total population, the problem may also be one of distribution. If the populations of excessively dense areas were ditributed more evenly, those of us not in imminent danger of living shoulder to shoulder might find our "lebensraum" rather more restricted than it is now.

You had a flash and called an electronics guy? Had you a flush, would you have called a plumber? Seriously though, when declared surplus to requirements in the computer industry twenty years ago, I literally switched off. Some googling of "super capacitors" will start you off, where dynamic balancing is often mentioned, but I think the best way of doing this is commercially sensitive. We need to shake the forum tree more vigourously and see if an expert falls out.

There are topics, Science based, where a serious question is asked, and a knowledgeable answer sought. That should be one category. There are other topics, e.g. Politics and religion, where no matter what the question, there is only opinion and debate. Here is my problem. A good debate requires two basic types of input: 1. Informed, well crafted and researched input. This does not, however necessarily lead to an energetic, lively, attention-grabbing and lengthy thread. Desirable, yes? 2. Spicey, combative, and yes, inflamatory contributions. These, I find, are more likely to force me to reconsider my own position.....The true purpose of debate. Humour: Much is contrived and, well, sorry, "childish". I prefer mine a little more subtle, the type that often goes unnoticed and is thus unlkely to gain much recognition. So I suggest, for maximum simplicity, three categories. One in the hard sciences, and two in other subjects.

helluva difficult place to park, is there a ladder so you can climb to put your money in? Not a great way to raise municipal revenue.

Check out "restless leg(s) syndrome". You may have a known problem.

In the context of feeding this seething mass, a couple of extracts from my morning news paper: "Military scientists are developing ways to harness the power of bacteria to to allow soldiers in remote battlefields to survive on a diet more suited to rabbits or cows...........But researchers are investigating ways in which beneficial bacteria could be added to the diet of soldiers, allowing them to survive for long periods away from food supplies by eating hedgerow leaves." "These bacteria are now being investigated under a long-term programme funded by the Defence Advanced Research Projects Agency (DARPA), funded by the scientific research arm of the US Department of Defence." So there you have it. For a full belly in times of food shortage, join the marines. It is rumoured that one grunt, asked for his opinion, replied "Moo".

I have been tinkering with some as storage for a gravity (weight) powered generator. Pro's.......can be charged and discharged at extremely high current, unlike ni-cads and lead-acid. Con's.......Do not maintain a constant voltage. When connected in series to achieve higher voltage, require dynamic balancing between cells. I either charge a bank according to the requirements of the "weakest link", or use cells of similar characteristics selected by test. No long term leakage observations to make, but short term no problems.

So if this "unelected" board was set up by an elected parliament, then that does raise some interesting questions, no?

Sysiphus: The Standards Board for England was established by Parliament in 2001 to enforce the Local Government Code of Conduct, which covers all councillors and mayors in England. If found to have contravened the code or brought his office into disrepute, Mr Livingstone could face a number of sanctions by the body, including being required to undergo training, loss of office for up to one year or even a ban from public office for five years.

You beat me to it, but I was going to say: balloon in box, some catalytic resin in balloon, inflate balloon, swirl around, when set remove box, you dont even have to tie up the neck of the balloon.

Here is a possible "PCS" type answer: A perfect cube only exists in theory. A cube made from physical material can only ever be an approximation. So perhaps the answer would be: "How good an approximation would you settle for?"

Truth does seem to be in short supply on this issue. As presented here (U.K), The port land is municipally owned, security remains in American hands, and and only the lease on some buildings is being sold. Perhaps that is why we are more pragmatic about it over here, and P&O is/was one of ours anyway.

My first reaction was : A metal that can not be machined? reminds me of an acid that dissolves everything, but the inventor could find nothing in which to store it.
