The two principle solar system missions here - Tandem (Saturn - Titan and Enceledas) and Laplace (Jupiter) require going beyond Mars, and a first for the ESA: they would probably be using RTGs (Radioisotope Thermal power Generators) - this will be a big cost, and also a big political step - the first Nuclear ESA mission.
Incidentally the proposed NASA-JUNO Jupiter polar orbiter is also a first - a *solar* powered orbiter for Jupiter - something that was not supposed to be possible! This is thanks to reduced power requirements and better solar cell/battery/computer tech. I would like to see the ESA try 2 missions - the nuclear powered mission to Saturn, and another cheaper mission using Solar, based on Mars/Venus Express architecture (with improved solar/battery etc) to Jupiter - maybe a Europa orbiter? The point is that Venus express cost around 200 million - by reusing the Mars Express system - why not try for a cheap Jupiter solar mission, which would be a first for the ESA..

Rather than, say, Utube. Having said that the BBC does make some good progs - but it could be done on much much less than 7 bill - heck for that, we could have a space program..
Analog? Huge waste of bandwidth, only needed to do it that way in the days of valves, switch it off. But, use the digital bandwidth for new HDTV services - dont just sell it off! (Keep analog radio though - small bandwidth). Incidentaly, just to show nothing is new, if I remember right, both Baird & German engineers had experimental 1000-line TV working during the 1940's - the problem was always the bandwidth (or the valve video amps that could work at high frequencies)..

but exhaustive search just seems like a waste of time and effort
Not so. The exhastive search approach provides a testable benchmark for true AI to exceed before it can prove it is productive AI. The famous Chess 4.6 program demonstrated that a simple "technical" tree search program could perform better than selective "intelligent" algorithms that tried to prune the search tree aggresively. With Go, this strategy fails - but the "intelligent" pruning mechanism is still eluding everyone..
There is still a golden prize in game-search algorithms - solve this, and other problems in AI can be solved too..
The 1541 had a 1 Mhz 6502 - more or less identical to the 6510 in the C64. The bugbear was the serial interface between the two (256 bytes/sec) - it was a "deliberately crippled" implementation of the IEEE 8 bit parallel PET disk/printer interface (super fast 2 Kbyte/sec!). Jack Trameil didnt want the VIC20 (first implementation) to compete with the "business" PET PC line, so it was given a slow interface. It was soon hacked, and you could get up to 35x speed - faster than the "professional" parallel interface.
The great shame with Commodore was the waste of many advanced ideas that landed on their laps - PET, C64 chipset, Amiga... Heck the C64 was still being sold with the *same* 1Mhz clock speed at the end in 1992, 10 years after release.
By the way, I would like to see the current copyright owners give the rights to the ROMS to the publiuc domain - they would have *more* commercial value (indirectly) if they did that than if they hang on to them in the hope of commercial development.. While we are at it, lets get all that abandonware in the public domain too..
And yes, they did boot up instantly - a 1Mhz 8bit C64/VIC/PET will boot up and run a simple typed in formulea or program faster than you can do it with a standard 3 Ghz 64bit PC today..

"You have to de-magnitize your CDs, CDRs, DVDs, Cables etc to get the most out of your setup! All kind of optical discs (CDs, CDRs, DVDs, SACDs and more) benefit from being demagnitized! The sound is clearer and with more dynamics and power. The same goes for cables! "
In fact *even* dye-based CDR/DVDR's can benefit! Now, wheres my VISA card..
Did you ever get the feeling you are in the wrong business? sigh..
People, its just a blog. If someone has really hacked Google, we will hear soon enough. Otherwise scamming and spoofing the ratings with rubbish sites is a sport thats been going on a long, long time..
Fair comment, since parent post was daft, but the situation is a bit more complex. First you have to look at the carbon used to make the biofuels - some will be used for fertiliser, tractors, transport, etc. Also if you are using plant matter that currently is being left to rot back into to the soil, (as proposed) then you are burning carbon that would otherwise be sequestrated - and stripping the soil of natural nutrients - and so on. You also need to use water resources which are increasingly scarce, and land which can be used for food - again world food demand is on the increase.
From what I have seen of the maths so far, biofuels only capture a few percent of Solar power net, so there is simply not enough spare arable land in the world to make enough fuel - especially as countries like India and China ramp up demand for cars. There is still plenty of sunny unused desert for Solar, or offshore sites for Wind, not to mention Tidal, Wave, etc.. Just use the power in its original Photon->Electron form, and bypass Carbon & Hydrogen altogether..
Hmm.. Or for 10 Gigawatts, you could use a solar plant about 10x10 miles in the Nevada desert. This sceme http://www.reuk.co.uk/Nevada-Solar-One.htm Delivers 64 Mw for 350 acres = 45 watts per sqr meter. 10 x10 miles = 260 000 000 m2, x 45 (watts) = 11.7 GigaWatt supply. Yup ok, day only - but you are charging car batteries, so you could work out a scheme that does that in the day. They reckon it costs around $0.07/Kwh.
You are right on one thing though - probably better to just generate & use electricity directly than to mess about with Hydrogen, etc. Think of all the plastic/glass you would need to contain the algea and collect the gas..
Solar cells, or a combination of mirrors and sterling engines, will probably always beat out organisms for pure efficiency. Doesn't mean we don't also want the organisms. Particularly when the object of the exercise is hydrogen production, since water electrolysis isn't very efficient either. In practical economic terms, bioproduction of hydrogen (or other fuels) may make more sense than using generated electricity.
I think the crux there is whether you want Hydrogen or Bio-fuel at all. Improvements in Batteries are making straight-forward electric cars more and more feasable - just use the electricity from solar/wind/tidal (and for that matter nuclear) directly, bypass the large inefficiency involved in Hydrogen or Biomass generation/storage (most of the storage methods for Hydrogen cars are very poor - less than 2% Hydrogen for overall stored weight). For example, (from another thread) I calculated you needed about 100x100 miles of Nevada desert to generate the complete daytime US gridload (approx 1 TerraWatt). This scheme in Nevada:
Delivers 64 Mw for 350 acres = 45 watts per sqr meter.
100 x100 miles = 26 000 000 000 m2.
x 45 (watts) = 1.17 TerraWatt supply.
Cost? Figures vary, but Nevada Solar quote about $0.07/Kwh, wind and others maybe a little less. I wonder how algea would compare, in terms of cost, land/water used, and so on..
Give me figures in terms of overall % efficiency - how many joules per m2 of sunlight area. How does that compare to solar cells, or other solar converters? How much water would be needed for the process? If so, would it need prime agricultural land, or could it be done in a desert region?
Whenever I have looked closely at Hydrogen/bio production, its a fraction of the efficiency of direct electric production - and/or requires unrealistic amounts of prime land..
Whenever I have seen the costs for these sort of schemes, I wonder whether the town/council are getting value for money. I think the best way is for local government to encourage local places that have net access anyway to provide a free service, in return for support, equipment or some small subsidy, rather than the over ambitious million-dollar schemes some places try for - I doubt they get the subscriptions back to pay for it all. If that works out to be popular, then expand it..
Is it? Read the extract of the report, below. The way I read it, it was only a series of operations carried out WITHOUT understanding what was happening that saved the reactor vessel - had the vessel not been flooded with water, 20 tons of molten fuel would have breached the vessel. The point was that this was supposed to have already been "impossible" - which begs the question - what other unforseen circumstances could have occured if the reactor vessel ruptures?
http://americanhistory.si.edu/tmi/tmi03.htm
4:05 - 6:00 a.m. The water in the reactor boils away, leaving more and more of the reactor's fuel "high and dry." The operators disbelieve the various indications of serious trouble (including rising levels of radiation in the reactor buildings). Lacking any direct indicator of the water level in the reactor, they fail to grasp what is happening: the uranium fuel, intensely hot, is reacting chemically with the zirconium tubing from the inside, while superheated steam is reacting chemically with the zirconium from the outside. The fuel rods are rupturing.
6:18 a.m. Finally recognizing that the PORV relief valve could be open, the operators close a manual back-up valve. But it is another hour before it occurs to them that if the relief valve was open all this while, then the reactor could be running short of water.
7:20 a.m. Pumps are turned on to inject water into the reactor. The core is finally bathed again in cooling water, but the water cannot penetrate the mass of collapsed and melted fuel rods. This dense conglomerate continues to heat itself up.
7:45 a.m. By now there are at least 20, perhaps as many as 60, operators, supervisors, and other persons in the control room. Although none is yet ready to believe that the core had been uncovered, radiation levels in the power plant buildings are so high that Nuclear Regulatory Commission regulations require the declaration of a general emergency. While state and federal officials are being informed of elevated radiation levels, unbeknown to all, a molten mass of metal and fuel--some twenty tons in all--is spilling into the bottom of the reactor vessel. The bottom of the reactor vessel is steel, five inches (13 cm) thick. But even that thickness of steel would not be expected to hold up for more than a few hours against such heat.
If this meltdown were known, or even merely surmised, drastic emergency measures, including evacuation of the region for miles around, would certainly be ordered by the governor.
9:00 a.m. The reactor vessel holds firm, and the molten uranium, immersed in water, now gradually begins to cool. The real danger is past without anyone knowing how great it had been.
What worries me even more is what will happen if the tech is operated in poorer contries with inadequate safety procedures and maintenance..
