    Well, actually some of the plant matter decays underground and turns into new fossil fuels, thus locking away some carbon -- but this process is very, very, very slow.

    But we need to cut the rate of CO2 production right now, even if we can't reverse it straight away. The longer we leave it in the hope of finding some magical cure-all, the harder it is going to be to clear up the mess even if and when we do find it. In the meantime, if we all specify gas boilers with electronic ignition {no wasteful pilot lights; especially not the Glow-Worm Swiftflow range, which need the fan running on half speed all the time just to keep the pilot alight} and energy-saving light bulbs wherever feasible {i.e. not used to illuminate moving machinery and not on dimmer switches}, and reduce or eliminate unnecessary car journeys, that will go some way towards offsetting the worst effects.

    To say that something is not good enough because it's not absolutely perfect is as foolish as to say that something is perfect when it is only barely good enough. We need an interim solution right now, and we need to recognise it as such.

    NO, because hydrocarbons contain hydrogen as well as carbon -- so when you burn something that has a formula of approximately CH2, you get CO2 and H2O, but when you burn H2, you get just H2O. The trouble is that the C-H bond stores more energy than the H-H bond, so you need to react more molecules of H2 with O2 for the same amount of energy output than you would CH2 with O2.

    But, manufacturing hydrogen uses water anyway -- it takes one molecule of H2O to make one molecule of H2 {and you get half a molecule of O2 as a byproduct}. If there is more water vapour in the atmosphere, it will rain more; but all that water, when it comes down, can be used up in the manufacture of hydrogen.

    For read-only, or even read-mostly, MySQL is blisteringly fast. It slows down when doing many INSERT or UPDATE queries on large tables because the whole table is held in one file, which has to be locked during a write and so slows things down.

    On Linux, with a disk caching policy of "Never, ever commit anything unless you have to swap something from RAM, or are about to umount the file system" and enough RAM to cache the whole table file, MySQL writes almost as fast as it reads. OSes with more conservative policies, such as insisting to decache often and verifying before releasing the RAM, obviously won't be so fast {but who'll be laughing at who when the power comes back on?}.

  7. In the UK ..... on Company Develops Microwave-powered Water Heater · · Score: 1

    Most people get their hot water heated by their central heating system. The most common types are: (1) a cistern-fed cylinder, with a coil of copper pipe in which water from the boiler is circulated {so the two water streams, from the boiler and to the taps, never mix, and the water in the boiler's heat exchanger is not being continually replaced} -- a three-way valve downstream of the boiler and pump selects whether to heat the radiators, cylinder or both; and (2) a combi boiler, an all-in-one system which uses a plate-to-plate heat exchanger to heat water from the mains as it is used {a flow sensor in the hot water piping triggers the divertor valve and fan/ignition cycle}. In homes without central heating, either cistern-fed cylinders with just an electric immersion heater {3kW}, or gas flow-heaters are used.

    The cistern-fed system has the disadvantage that hot water pressure is limited. So showers in the UK are most often heated by an electric flow-heater, usually 7-10kW -- unless you have a gas flow-heater or combi boiler, or the shower is on the ground floor and the piping is mostly 22mm and mostly straight down.

    It's a law of nature that it takes 70 watts of power to heat one litre of water one degree hotter per minute. If the water is coming in at 10 degrees and you want to heat it to, say, 40 degrees, then you will need to put in 2.1kW just to get a flow rate of one litre per minute! An 8.4kW shower will give you 4 litres a minute at 30 deg. differential, but it will require a 35 ampere supply.

Provided that you use true analogue lowpass filtering between the D-to-A and A-to-D {clue: I mean passive filtering; real inductors, and absolutely no polyester capacitors anywhere}, it will work with hardly any quality loss. Remember, analogue technology was used for years, and all its shortcomings were understood and overcome before the shift to digital.

But let's just say that there's no way for the dumb, read-only CD even to be certain of, much less do anything about, what lies downstream of the laser head, and that's where the problem begins and ends: the act of reading the CD for the legitimate purpose of listening to it is, on some level, utterly indistinguible from the act of reading the CD for nefarious purposes such as copying it. Of course, you might well have a right to copy it anyway: think Fair Use / Fair Dealing. If you've a cassette player, but no CD player, in your car, then you are allowed to make a copy of the CD onto a cassette as a necessary step in listening to the music on the CD -- your common law property right by virtue of ownership of the CD -- in your car. It only infringes copyright if you part with the CD and retain the cassette for longer than is reasonable for you to get around to recording something else over it, or if someone steals the cassette -- and they are the infringing party. You were merely aiding and abetting copyright infringement, but ignorance of the fact is a defence. These rights aren't set in stone anywhere, because exactly what constitutes Fair Dealing is determined by the courts; but face it, no court in the land is ever going to send you down for taping albums -- hell, even the judge probably has a few in his car.

Does anybody ever illegally photocopy the Times, the Penguin Shaggers' Gazette, the Woman's Monthly, or the latest Harry Potter novel? No, of course not.

    The fact is that CDs are overpriced, and downloading offers an economically viable alternative to purchase. Downloading isn't free: it takes up time, bandwidth and drive space that all have some value to the downloader. If the intention is to burn the tracks to an actual CD, then this requires additional resources: a jewel case and about 1.05 blank CDs {remember the hit rate is not 100%}. Recreating the CD packaging -- even crudely -- will require further resources in the shape of paper, ink and time.
