hydrogen, at a fairly efficient processing level with wind power supplying energy for electolisis, would cost about $4 / gasoline gallon equivelent of power. thats not so great. we will likely not develope a more efficient means by clean technologies for quite some time.
if hydrogen is produced(refined??) from coal or petrol generation it would still be nearly $3.50 / gasoline gallon equiv.
hydrogen is NOT the answer short term.
the answer for immediate energy problems and environmental issues is large scale conversion to bio-diesel.
bio-diesel can reach a cost of just $1 / gasoline gallon equivilent AFTER the initial infrastructure is built. AND, biodiesel would stimulate north american farming economies by providing steady cash crops for southern mid-western farmers growing efficient crops like algea.
how about! MacX86OnLinux. how to run OSX on commodity hardware! thats how! works great on powerpc lines, so it should be a simple 'port' to x86.
then a small linux system, grub boots system, init starts driver services, and then starts Mx86OL!! then linux drivers can fill most of the void of pc hardware not supported on MacOS x86.
Also, I'm not sure how easy it would be to do, but you could pass the PCI,Firewire, and USB bus straight to the MOL system, or at least you could give MOL complete control of some devices so OSX could use native drivers on anything that is supported.
BUT, you could use that same solar energy to increase the temp delta from the hot and cold sides of a stirling engine and stirlings get MORE efficient the higher the tempurature delta.
does smoking crack hurt others? well, do you have a family? if so then yes. do you act in an insane manor and pose a threat to other people when in public? yes. now if you are locked in your home by yourself then i suppose smoking crack only hurts you.
and IMHO if you WANT to be an idiot, your welcome to do it because you may just kill yourself and raise the collective IQ of the community.
as you get moisture in, the soil will compact around the pipe creating a 'sheath' of soil that will start to become so dense that it will both block water and insulate the pipe.
it would be more efficient to use a stirling engine than a slow water vapor turbin. natural evaporation will not build pressure fast enough to turn a turbin fast enough. it would work but it would be less efficient that a stirling.
a)underground sweating of pipes is not very effective BECAUSE the sweating is atmospheric condensation, in the ground you will just pull condensation out of the adjacent soil. though it would have some effect, it would not be a complete irrigation solution as soil does not flow like air:)
b)colder water from the depths would produce a LOT of condensation on a hot summer day, but the cost of pumping will reduce the efficiency of the method. consider that pumping will not be extramely expensive, similarly as expensive as pumping the volume of water horizontally because you dont actually lift a volume of water, just displace the water on the bottom to the top and the ocean does the work.
c)very cold water on ocean floor, mildy cool water to warm water on surface = nice temp difference. enough to run a sterling engine on to produce electricity. coupled with solar heat collectors this would infact be practical in some areas.
Have you ever heard of the "broken windows" http://www.cityofseattle.net/police/prevention/Tip s/broken_window.htm [cityofseattle.net] theory? Your house does not exist in a vacuum; besides the reduction of property values, you could be contributing to vandalism and other crime in your neighborhood if it looks like a piece of shit. What if you never mow your lawn and it gets infested with insects/rodents/etc., some of which decide to invade my place? You better believe you'd be responsible for it; the regulations help keep these kinds of issues from going to court.
We have all of these extra laws and ordinances and so forth because some people don't have respect for others' property. You are part of a society; again, you don't live in a vacuum, whether you'd like to or not. Most people feel a social obligation to keep their lawns reasonably neat and not leave their garbage cans in the street all week; they know that they are less likely to get the respect of their neighbors if they don't./Most/ of the time the ordinances aren't intended to force people to act in an unreasonable way and are in fact best for the community as a whole. Similarly, safety and emissions inspections on vehicles are best for the community as a whole. They may be a hassle for you if your car is a piece of junk, but the direct and indirect consequences of driving a vehicle that does not pass these inspections outweigh the inconvenience and restriction of freedom to you.
so my insects destroy your lawn? thats pretty direct right? i mean my neglegence was fine until the damage fell on your lawn. you see? my property directly damaged yours!
"best for the community as a whole" = communism
the needs of the many outweight the needs of the few = communism
in america, the individuals rights are supposed to be at the apex of any law. so screwing one guy because everyone else wants something a certain way is a violation of that persons rights!
it would be 'better' to just kill anyone that did not contribute to society. overall it would, but that disreguards that persons rights. and that is the most extreme case but it is a violation of the same rights(+the one where you dont kill) as forcing a certain action with pain of penalty like make people fix a broken window.
putting up loose sheet metal all over you home = make the sheet metal secured to the building!!
as a side note: contract = agreement to do something that you have the right to do or not due, and being legally bound to fulfill deal. a)sex is legal, b)buying services is legal c)buying sex is illegal???
no, those laws dont and wont work because 'justice' systems have room for allowances and opinions.
justice is facts and rights, not opinions. in a real justice system their would be no judges and these laws would work with a much better 'right' answer rate than any justice systems in place today.
technically, the RIGHT way is to allow a person to do anything or have their property in any state that does not infringe on anothers same rights. this is the CORE concept of liberty and ownership.
so, if crack were legal and you could somehow keep people that are using crack on a piece of property without them traspassing, or throwing trash on, distrubing the 'peace' like noise levels or smells etc, or anything else damaging(directly), then it would be ok to have a crackhouse.
the nature of the crackhouse makes it unacceptable, because of all the things that come with being a crackhouse like noise disturbances, gunshots, trash and rubbish being left on the lawn(to blow to the neighbors property), theft.
you see, the crackhouse or anything that land is used for should not be "zoned" with neighbors property value being taken into account. polution laws, reasonable noise laws(reasonable being a level set for the exsisting neighborhood before developing a piece of property,more on bottom *A*)
each law shouldn not need to be writen in such great detail or writen to be so descriptive BECAUSE the other simple laws to govern the people will also be applied to any situation.
laws a)dont physically injur others b)dont steal or damage property c)do not harras, or become a nuisance via derogatory or explicit effort
now how many circumstances does this cover for 3 simple laws? just think about it! add d)obey willfully signed contracts e)pay fair taxes f)do not fraud. fraud to be considered theft.
and nearly everything else in 6 laws!
*A* in a residential are, if their are people living in houses then the noise level allowance will be that of a residential! quiet! but if the piece of property had nothing within the range of the sound, then not sound rules! but if an industrial is in the immediate area, then noise levels up to safe levels are tolerable.
--
ok, directly on subject
do the metal coverings damage the neighbors property? produce excess noise? fall of and land on neighbors property or in act of swinging cross the property line?
the only way property values should have bering and a persons rights is when DIRECT damage is being done. for instances: 1)you are burning your house and you catch your neighbors house of fire! or less extreme, the odor/smoke is drifting onto their property. 2)you have weeds, your weeds are spreading to your neighbors property. 3)anything else not along these lines, go F'ING LUCK!!!!
1)Copyrights should expire in a reasonable time and be non-renewable. Like other posts above, I think 5 years is enough. I do not think that their should be any requirement to distribute source code. After 5 years the software is free game BUT does not carry any 'GPL' status and can be held on to for as long as one is capable.
2)Trademarks should not expire! Disney should be able to have "Mickey Mouse" but after 5 years another party could use any party of the mouse EXCEPT the trademark(s)
starwind will allow you to export images or even drives and partitions to iSCSI. WAY less overhead and way faster than smb. I can only get about 6MB/sec over 100 speed ethernet and SMB, but i can get ~10.5MB/sec with iSCSI.
simply add a number of these disk images accross your network and then mount them on your linux system. you can use LVM to manage these volumes also.
i have to warn your that 100 speed ethernet is a bit slow for data storage on a network especially when you look at it like:
comp A wants data in/share/vol1 on the server X 1)A requests data from X. 2)X requests that data from B where vol1 is stored 3)B sends data to X 4)X sends data to A where a normal file server is just A->X->A or 2 steps over ethernet, its now A->X->B->X->A or 4 steps, doubleing the load on the network.
MANY US cities could support highspeed rail systems very effectively. the population density of a city is not THE on important factor but cost/meter/traveler vs price/traveler/trip. any rail should be slightly more than self sufficient to allow 'free' expansion(as in the rail system can afford to build new stops without a tax levy or loan).
!!!!!!!!!!!!those not interested in a long sprawling post, move on now!!!!!!!!!!!!!!!!!!
i now live in a city of just 120,000 and it could support a highspeed rail system for itself and two small communities next to it for a resonable price. something along the lines of the TGV and metro(france) or 'UNDERGROUND'(london). in a town like mine, trains could run as frequently as every 15 minutes and still be self sufficient.
i have work for BNSF and have a good level of knowledge about modern train systems and costs and small US cities can afford trains! a high speed train uses less fuel per meter hour of travel with 4 passenger cars than today's semi-trucks.
ignore the overall cost of rail for a moment as people see $2billion as a lot of money but fail to break down that pricetag to a percity and intracity link prices. each city could build a local transit rail system, then cityies can split the cost of intracity link between the two cities involved and have small towns between pay for the rail and station in or next to that city. just like $1,000,000 is a lot of money except when 1000 put in $1000. it still has a pricetag but it is managable and promotes more intracity travel when the rates are low.
small communites often do not have jobs for the population and a high percentage of the population commute to the larger cities nearby. Rail is cheaper for these people and often faster. the daily commute cost could be reduced by %50 plus the commute time is not spent driving and can be spent in more productive ways, like sleeping!:)
i once lived in london(hendon!) and used the oyster cards and paid about 100BPounds/month, which is ~$190 but IF this were in america it would be right around $100/month. and though london has a great system, it is old and costly compared to more modern systems like tokyo(i havent been so im going by readings on this!)
Programs that don't work this way, and require specific installation/library file locations are broken and should be fixed - there's no need to design a new file system.
that was my point actually. in an open system(i believe) such as open source, one must work within the system to integrate and not try to ignore other systems because they are not as efficient as they could be. we just dont have the resources. what we can do is modify some of the more important or at least highly used systems and try to steer development out way.
also, many programs do not install from an rpm or apt-get or package manager in general into a home directory all that well. this would allow unmodified installs easing the process.
dont get me wrong, i think that many systems need overhauled.
we need a stack file system. where the base file system is / and the stacked file systems are difference files for each user.
for instance.
/ /home /home/username.diff.img
notice no folders in home, just difference files.
login
mount -o diff_filesystem/home/username.diff.img /
this mounts a filesystem right on top of the old file system. and gives full read/write access to the / BUT all changes are saved to the diff.img rather than the / filesystem. this would allow unpriviledged users to install programs(if allowed to by making rpm/apt-get/emerge/etc etc suid root or something) and alter many many settings BUT not be able to mess up the base system OR other users.
i know that this is a generic and incomplete solution as no user should have access to another users files BUT this could be handled in the stack filesystem module forbidding access to other home directories or root definable files and folders.
so root could modify/etc/difffilesystem.exemptions when logged in as root and adding a line /etc/difffilesystem.exemptions -wrx
would make it so the average user could not wrx that file or /home/* -wrx /home/$USER.diff.img +wrx
would deny access to/home and then allow access to that users home only.
i do this because unix file permissions would not be valid because any changes to the files would be written in the difference file so no changes would be made. of course the exemptions file should have an option
/path/to/file/or/folder/* =unixfilepermissions
or something like that to use the base filesystems permissions for those files.
so the AVERAGE user would have an exemptions file like
##commented out for priviledged user
#/* =unixfilepermissions /home/* -wrx/etc/difffilesystem.exemptions -wrx /home/$USER.diff.img +wrx
so, the exemptions file would allow some users to install software via traditional install programs like apt-get or rpm without the need to modify those programs OR run as root.
it would allow you to limit the folders users could modify so they could not re-run daemons with different settings in their userspace after editing the configs.
and it would allow a side effect of makeing the users home directory a single file with its own filesystem. the / could be ext3 but the users home folder and all modifications could be reiserfs. AND the root filesystem would always be intact.

Well, this is NOT a stupid comment because using 1.5 minutes to boot up on a laptop, which is a pretty strenuous 1.5 minutes and eats more that 5 minutes worth of normal use battery power, can really add up. this makes people less productive on their laptop and more reluctant to pull it out for some quick work.
also, SOME people choose to only pay for electricity when they are using their computer!
anyone who argues that they can leave their desktop on for months at a time without rebooting and then calls others idiots for not considering the same thing acceptable are hypocrits and down right ignorant and stupid.
welcome to global warming and excess energy use asshole.
hey, who cares how long it takes for your 36" TV to turn on, i mean it doesn't matter if you leave it on all day and night for the entire year right? all those idiots who turn their TV off when they dont watch it.
i like my refridgerator. it cools so well that i dont even have to shut the door. i think people who keep the door shut are stupid, i mean they waste all that time opening the door when they want food. they could just leave it open andn have quick access.
i dont usually openly insult people on slashdot or anywhere else for that matter but the people im talking about are just plain idiots.

also, many programs do not install from an rpm or apt-get or package manager in general into a home directory all that well. this would allow unmodified installs easing the process.
dont get me wrong, i think that many systems need overhauled.
here is MY solution to this.
/
/home
/home/username.diff.img
/home/username.diff.img /
/etc/difffilesystem.exemptions when logged in as root and adding a line
/etc/difffilesystem.exemptions -wrx
/home/* -wrx
/home/$USER.diff.img +wrx /home and then allow access to that users home only.
/path/to/file/or/folder/* =unixfilepermissions
/* =unixfilepermissions
/etc/difffilesystem.exemptions -wrx
/home/$USER.diff.img +wrx

i know that this is a generic and incomplete solution as no user should have access to another users files BUT this could be handled in the stack filesystem module forbidding access to other home directories or root definable files and folders.
so root could modify
would make it so the average user could not wrx that file or
would deny access to
i do this because unix file permissions would not be valid because any changes to the files would be written in the difference file so no changes would be made. of course the exemptions file should have an option
or something like that to use the base filesystems permissions for those files.
so the AVERAGE user would have an exemptions file like
#base config
#other options.
while a more priviledged user would get
##commented out for priviledged user
#/* =unixfilepermissions
so, the exemptions file would allow some users to install software via traditional install programs like apt-get or rpm without the need to modify those programs OR run as root.
it would allow you to limit the folders users could modify so they could not re-run daemons with different settings in their userspace after editing the configs.
and it would allow a side effect of makeing the users home directory a single file with its own filesystem. the / could be ext3 but the users home folder and all modifications could be reiserfs.
AND the root filesystem would always be intact.
just some thoughts.

also, SOME people choose to only pay for electricity when they are using their computer!
anyone who argues that they can leave their desktop on for months at a time without rebooting and then calls others idiots for not considering the same thing acceptable are hypocrits and down right ignorant and stupid.
welcome to global warming and excess energy use asshole.
hey, who cares how long it takes for your 36" TV to turn on, i mean it doesn't matter if you leave it on all day and night for the entire year right? all those idiots who turn their TV off when they dont watch it.
i like my refridgerator. it cools so well that i dont even have to shut the door. i think people who keep the door shut are stupid, i mean they waste all that time opening the door when they want food. they could just leave it open andn have quick access.
i dont usually openly insult people on slashdot or anywhere else for that matter but the people im talking about are just plain idiots.
