Accually using the waste as a propellent how ever gross that might seem would be a good ideal to use on a fast muclear interplanetary mission.
Esp if it's propeled by an electric arcjet or linear accelerators.
If the waste is propellent then carrying extra food would not be a huge weight penalty since it's going to end up being extra propellent in the end.
On a mars or moon base waste could used in a bio digestor to make methane the left overs could be burned in a solar furnace and then used as a safe fertilizer or just be thrown in a dual loop biomass recycling system which nasa has demonstriated allready.
In dual loop first said waste fecus and urine are used to fertilize reeds and other swamp type plants which will produce H2O vapor and O2 these can be composted giving methane a good rocket fuel and whats left could be used as a safe growing medium for vegtables.
There are many dangers to having your tomatos and melons growing in raw fecus the dual loop system or burning it first adviods this danger.
You wouldn't want your astronuats to end up getting colera or worms space travel is danerous enough as it is.
Acccually ISS only recyles water vapor in the atmosphere at this momet which is where 90% of the water lost by the human body ends up.
The urine recycling was one of the sugestions but has not been implamented yet one it requires a flash vaporizer or a pasturizure and some plants to implament safely either of wehich would require more space than is in the base modules but is planned to be added in a new US service modules.
Accually planes don't make use of the vortexs for added lift they'er parisitic drag in planes.
Some plane have winglets to reduce these vortexs and thus the drag.
But insects do make use of vortexs to gain lift in flight it explains why a bumble bee can fly and fly very well.
The insect will twist it's wing casting off a vortex just before the up stroke and accually makes lift because of the reduced pressure from the vortex .
About 45% of total lift in insect fight is in the up stroke because of this.
Birds are also suspected for using similair priciples in certain modes of flight.
One ideal for prereenrty inspection would be to carry a simple free flying satilite with a high res CCD color camera and a simple cold gas manuvering system.It can be very small too 50lbs .
Also keep an EMU and an ablative expoxy repair kit on board as well kinda like what was suggested in the early 80s but discounted as unnecessary.
The inspection sat could also be given manipulators so it may be able to do the repairs.
As for rescue keeping a shuttle on standby would be costly but keeping something like the x37 or a modified ie streched apollo ready would be much cheaper.
launch them unmanned so all space is avilible for rescue.
Why make a semi truck do a job that can be handled by an SUV or van?
Have it dock if theres a docking adapter on the spacecraft in trouble other wise an emergancy EVA will be needed again the inspection bot could help here too as they all have pressure suits just add some self contained oxygen for EVA. "BTW in gemni their EVA suits were basicly pressure suits similair to what was used on the U2 and SR71!"
So Im pretty sure the shuttle launch suits would do the job for an emergency EVA quite well.
What we need is to think outside the box.
Accually the most reliable spacecraft is apollo block 2 with only 1 catatrophic failure apollo 13 the crew survived .
The apollo 1 was a block 1 version and had many flaws which were fixed in block 2 soyuz 1 would have been equilent to it.
Also apollo can carry up to 5 people thgey had a 5 place apollo during skylab for rescue it had two extra seats in place of the moon rock sample lockers so two people can fly it up to sky lab and recue the three astronuts on it if needed nasa almost had to use it once.
If your going to resurect any older apacecraft it should be apollo but of course modrenised with new computers and a N2 O2 atmospere gemini was almost too small for 2 people BTW apollo is relatively roomy.
The most reliable launchers are the saturn series the saturn 5 in preteculiar with no major failures it's the only rocket with a 100% success rate the second most reliable is the shuttle with one launch failure and one breackup on reentry out of 107 launchs.
A saturn 5 or shuttle-c"Shuttle stack with cargo and no orbiter" would finish ISS 4 times faster too BTW.
Shuttle-c would be very cost effective and a modernized version of saturn 5 would also be relativly cheap both offering $2000 to $3000 a pound cost which would under cut the europeans and chinese while at the same time being safer than their launchers.
Yes unfortunetly they can't do everything if they still had enrgia and buran in service they could but unfortunetly they don't and it would take some 5 years to start up production of energia if the US gave them the money.
As for the Nixon administration crippling the shuttle the most damaging thing they did was kill apollo which cause the STS to be rushed into service and the loss of skylab.
There was no manned space craft avalible as a backup if a problem that would ground the shuttle happened.
An apollo would also made a better lifeboat than soyuz since it can be modified to carry 5 people.
In the 70s they had a rescue apollo with 2 extra seats inplace of the storage lockers for moon samples for a total of 5 seats.
As for a near term replacement to columbia they should make a shuttle-C basicly a shuttle stack minus the orbiter and replaced with a pod crarrying the SSMEs recoved with a simple areoshell heatsheild and a cargopod so nearly all the weight that was shuttle is cargo.
A paylaod equal to or even greater than the saturn 5!
Such a setup is good for over 100 to 135tonns.
Possible more if they use diposible RS68s in place of SSMEs.
Also this would be a cheap launcher with over 5x the cargo using the same hardware and the same cost so it will be 4 to 5x cheaper perpound than the shuttle probley the most cost effective space launcher ever.
Definitly will under cut the europeans,chinese and even the russians for very large payloads.
I have to agree PCI-SIG is going overboard
Also they are money grubbing come on the a paper copy of the PCI spec used to cost $40 and included a free CD of PDF now they want $1500 for access to online PDFs are they smoking crack.
Sorry they are being jerks just look at the price increases .
It seems microsaft is behind this one they'll try anything to stop free software.
Maybe manufactors should expand agp to be multislot its way faster than PCI and the people holding it are not jerks.
Maybe someone should invent a a truely open optical type buss connector since IBM research has made it possible to put silicon LEDs on a chips so an electric/optical hybred buss that would make even PCIX 2.0 look like that of an apple 2 is technically fesable and probley cost effective.
reactive armor would not stop all weapons.

Electric Armor

It would help in defeating the random RPG/TOWII attack but would not be of much use from mutiple impacts from kinetic kill projetiles like what one would get if attacked by a weapon like the 30mm avenger cannon in the A10 tunderbolt II the discharge may cuase the first few round to explode if they are exploding rounds but not the other 20 to 70 rounds comming in.
In short it would offer no protection from that type of weapon.
Don't forget longevity I doubt it would last more than 30years if built.
Pervious houses lasted for generations but prefabs are not long lived stuctures.
If House A takes more material than house B but house B only last 30 years while house A lasts 90 to 150 years then I have to say you'd endup using 3x "including maintance/upgrades to the the traditional home" the materials with design B in the long run.
The basic concept had been done before by Buckmister Fuller .
In 1950 he demonstraited a modular home that could be reconfigured even the bathroom was a single module with plumbing for the tub,toilet and,sink all ready connected.
This ideal even looks like some of his early work before he made the domehome.
As you know the ideal did not catch on back then and probley would not today .
The track home aka suburb won out.
Some ideals that seem great on paper end up inconvenant in practice.
Also most upper class people in HongKong either has or are leaving the city since China has taken over who can blame them I'd leave too if an oppressive gov took over.
As for the gadgets my updated 100 year old victorian has the same stuff ethernet/802.11b updated climate control I can control via phone if needed and it looks a whole lot better to boot .
Also unlike the modular flat it's walls accually deaden sound and the inside doesn't look like a cubical.
Umm the whole activation thing is what made me not upgrade to XP products.
If feel it voilates my rights for them to know what's in my computer.
I should only have to buy it,install it,set it up and use it .
Asking anything more is asking too much form users.
Also why should I have to reactivate just because I changed my MB,CPU or videocard this esp can be an issue with OEM PCs as they usally come with crap video and too small of a HD that end up needing upgrading.
The whole activation thing did not help M$ get money from me if anything it caused them to lose money they would have otherwise got and their competitors to get that money instead.
Not a major issue for me as Linux is more stable anyway and staroffice 6 opens all the files I need to use.
Another dumb a$$ ideal that comsumers including myself will not stand for also it doesn't work in existing CD/DVD players it's adaptable to new drives with minor mods.
Is short another lame ideal that should be never implamented and then forgotten.
Another thing what techi could invent something to help the RIAA and MPAA and beable to live with themselves I couldn't.
I've done the same thing with no problems so I can watch the basic service channels 2 - 70 on my computer's TV card and have a tv in the kitchen.
Also I has had problem with dobly on my digital cable and I don't like the lack of SVHS and opical dobly audio connetors on the box.
Other minor problems most universal remotes don't support this box and it's remote does not support my TV so I'm stuck with two remotes.
LCDs die too and they're full of a material of questionable toxicity the organic liquid crystal is a mild carcinogen.
And yes LCDs do have a life span EBAY is full of other wise working notebooks with cracked which happens too easily or just simply dead
LCDs or ones with several dead pixels.
Flat screen plasma displays are the one's that could in therory last forever same basic tech as in a vaccuum florescent display I never saw one of those die unless it's been smashed or cracked.
As for phasing out lead this will add some to the cost not much as the substitute is a silver tin alloy but it'll make recycling more
attractive as these metals have more value but also it'll be safer.
I agree they have robots that asemble the stuff why not one's to disassemble it?With modren computer tech it sould be very possible to build a bot that can read IC numbers and remove the IC safely and cleanly and also recycle the lead in the solder to use in other products such as batteries or more solder BTW lead acid batteries are recycled at 95% of thew time now.
Maybe something similair to the machine that recycles cars even.
Also I to ask where is my flying car and my ticket to goto space and the space colonies?
So far the 21st century has been a real big let down.
Most US trast gets buried or recycled in the US that trash that gets dumped in China comes from places like Japan,Singapore and Thialand and they are just as bad about throwing out electronics if not worse once they get old.
Also it is very sad as China can't afford to have it's land and drinking water polluted since good arable land is hard to come by there as most is unusabley mountainous and or arid and the fact they a population of 1 billion on top of that.
It's your basic High School Chemistery
2 e+H2O+(Na+) Cl- --> 2NaOH +1 Cl2 both these products kill bacteria and viruses.
I'm supprise no one hasn't tried it before for cleaning but it's a very old process thats how all commercail lye is produced the clorine is a valuble byproduct in the lye making process.
Acually it was Tesla who invented a light bulb far superior to Edison's only 9 months after the invention of the incandesant light.
Telsa invented the Iduction light which moderm florescents are based partly but tesla induction light was cold cathod to start with as it use radio waves to excite a mercury vapor to radiate UV which in turn caused a phopherous coating in the bulb to floresce.Florescents use direct current to excite the mercury vapor the rest is the same process.
It used a miniture tesla coil for the RF source and was expanisive and is only recently being used commercailly as solidstate electornics have made it more cost effective.
This type of light can last for decades though in solid state form while getting 10x the efficeintcy of a standard bulb.

The same laser also powers the chip.
