Resolved Question: Is solar power really green? ***A Must Read***?

First off, Solar Cells are made from Silicon, which sounds harmless.... In order to understand how a solar cell works, a little background theory in semiconductor physics is required. For simplicity, the description here will be limited to describing the workings of single crystalline SILICON solar cells http://www.experiencefestival.com/a/Solar_cell_-_Theory/id/5376728 Are Solar Cells Poisonous..... According to the Silicon Valley Toxics Coalition, the gas sulfur hexafluoride, commonly employed to clean reactors in silicon production, is considered by the Intergovernmental Panel of Climate Change to be "the most potent greenhouse gas per molecule; one ton of sulfur hexafluoride has a greenhouse effect equivalent to that of 25,000 tons of carbon dioxide." The manufacturing of solar power panels consumes a lot of silicon, presenting us with a nasty paradox. If solar power production is ramped up as part of a global effort to reduce the greenhouse gas emissions produced by burning fossil fuels, the chances of accidental releases of sulfur hexafluoride in the silicon production process will only increase, which, says the SVTC, could "greatly undermine the reductions in greenhouse gas emissions gained by using solar power." I hope you noticed it said....one ton of sulfur hexafluoride has a greenhouse effect equivalent to that of 25,000 tons of carbon dioxide so in production the gas it gives off is 25 times more dangerous than CO2 in greenhous gases And government surpresses regulation of the silicon companies resulting in unregulated gases released. http://www.salon.com/tech/htww/2009/01/14/toxic_solar_power/ What about the potentional waste ... The usual story told about e-waste is... it's toxic," said Chintan Director Bharati Chaturvedi. "There's no mention of the people involved. There are not conversations about these human beings. http://www.nowpublic.com/environment/environmental-activists-expose-dangers-e-waste And the many other enviromental issues not listed here, but the real story is why are they reducing CO2 but it will boom the increase of sulfur hexafluoride which one ton of sulfur hexafluoride has a greenhouse effect equivalent to that of 25,000 tons of carbon dioxide. When will the true global warming effects from mass producing the solar cells and electronics to produce enough energy to replace 1 coal plant be reported by the media? And you believe Solar is GREENER than Coal.....think again. Dems wont read it, they wont research as it is or think This is solar panels ...read and comprehend Are you saying the study by Intergovernmental Panel of Climate Change is wrong? That would throw everything into the trash then People read the technicals and study it  more

Open Question: Can Anybody Find Anything But Hot Air in the Climate Bill?

This question is asked sincerely by a lifelong enviro. A supporter of Al Gore. But this bill appears to have been written by the coal companies based on 25 year old ideas, many of which were accepted by G.W. Bush the Moron President. The whole idea of the market based solution -- the cap and trade solution -- making a market in pollution permits -- maybe having them brokered through a firm like Enron -- which I think did actually broker some of these permits for a while -- that idea is 25 years old. It is not change. It's just slapdash legislation based on making the old dregs by bygone ideas look like a new bill by updating the year and putting a new cover on it. It's like the old news that CBS, NBC, and ABC purvey -- stuff from a few weeks ago -- offered today as your "news". Nobody in America is willing to do any part of their job anymore. It's a nation of AWOL officials and AWOL staffers and AWOL employees. If they wanted a real climate bill, they would have included funding for the hydrogen technology. Ways to electrolytically dissociate water efficiently. Ways to store hydrogen efficiently. Ways to burn hydrogen in fuel cells, or in turbines (possibly combined with methane to make hythane (R). There would have been a huge push for the sorts of thing T. Boone Pickens is recommending. Natural gas powered trains would have been in the mix -- and transcontinental tracks for same on the median strips of East West Highways. Geothermal would have played a huge role. It is a very rich power source in some places, always on, not like solar or wind. Hawaii could power all seaborne freight in the Pacific with Geothermal based Hydrogen Fuel Cell Gas. Tidal Hydro would have been in the bill. Micro-scale wind generators (egg-beater style) would have beeb there. The National Energy Spine (super efficient cable from coast to coast) would have been there. This creates conservation by allowing energy to be wheeled from coast to coast so peak loads can be met with cheap energy on both coasts. Instead we get the ancient mantra "Let's find a market based solution (that way G.W. Bush The Moron President, and the Republicans can be happy). No breakthroughs please! No movement away from fossil fuels, and certainly no less coal or oil! We'll just do this with financial manipulations, sort of Enron style, with pollution permits, create a playground for the K Street lobbyists, make it look like we are doing something because what we do is so complicated administratively.That way we can do nothing -- and nobody will know. With or without cap and trade the carbon footprint of the energy plants was bound to be legislatively reduced in future years. Cap and trade just bring Federal Pre-emption and knocks out the states ability to legislate on this matter. It's a form of state legal dis-ablement. It's a form of permission to just keep on keeping on -- more of the same. The climate bill looks like a 100% perfect fraud, from the gitgo. Mr. Axelrod thinks it has a fairly good chance in the Senate because of the writing changes that were made at the last minute in the House, and on this he's probably right. Coal can see when it has a good deal. The whole issue now will be off the table for the next 10 or 15 years, and there are 10,000 ways that the "caps" can be removed or made more lenient, triggered by all sorts of extremely complex micro-pico-nano regulations that only the coal companies have time to figure out and understand and know how to lobby with. They can get out of the caps. They get a vacation for 15 years. They get out from under state laws. Whee ! ... this pollution stuff is easy! All politicians are politicians. Nature is always Nature. So the Canute story is always apt. The vanity and the lies and the fraud never actually trumps nature, so you can count of on the climate to keep warming up and the CO2 levels to keep going up and the sea level and storm damage to keep going up. If we truly wish to stop being a hypocrite nation, we've got to get rid of all politicians. Put a truly independent agency in charge of climate change mitigation -- something like the Federal Reserve or the FCC or the NRC -- it's got to be able to make and implement rules smoothly and quickly. It's got to be run by Chairmen with long terms of office, at least 10 years, 15 would be better. The Chairman has to be mission focused, not politics focused. If can't get around the Canute Problem (The problem that wise King Canute taught his ministers about based upon knowing that Politics never trumps Nature)., we can't deal with the climate change issue. This new bill, is just more hot air. Maybe you can find something in it and tell me about what you think is there. Anyhow that's my question, asked by a true blue enviro, an AlGorista (with rhythm, hence an algorhythm, I'm a poet, I know it, float like a butterfly effect, sting like a karma-effect). For Dana the Master of Science -- I know that H2 is not a mobile source fuel and never will be. For fixed point fuel cells, no problem, especially if mixed as Hythane (H2 + CH4). Here is Gao Bwo Fu, Doctus Juris, Magister Plutus to tell you read my book, "Cost-Effective Ways to Comply with the New Clean Air Act", or my articles published by Herald-Mail. H2 is not a fuel for mobile sources, but it's fine for fixed point sources. If you want conversation why do you block all e-mail so I have to use this question extension to answer you? You can reach me by e-mail real easily, master of science (and where is your 600 page book on the subject of hydrogen burning -- cause mine is in the libraries). Never smarty-pants a smarty-pants. Scepticism is next to Godlicism. I know it. This science-thinker atheist says, "Bless you, keep those good questions coming!"  more

Voting Question: What kind of trouble will I get in?

Last night, me and a friend were walking around at night, and heard this kid we didn't like was growing marijuana in his backyard. So we went to his house and dug it up and threw it in a bucket. Now I don't smoke weed, or never even tried it (never even smoked a cigarette) we just took it to make the kid mad and show are other friend we took it (plus I'm not 100% sure it was a marijuana plant, because I have never seen one in real life). So we were walking outside with it, and a cop pulled up to us and i set it down, and he came up to us asking what we were doing and everything, and found the plant. He hand cuffed me and put me in the back of his car. I'm 17 years old and live in Michigan, and I guess I'm considered an adult here, so when i got to the police station they took my picture, finger printed me, and put me in a holding cell, saying they could hold me for up 48 hours. My friend was only 16 plus he wasn't holding the plant so they let him go. My friend had tin foil in his wallet so they thought we were going to smoke. I don't smoke but he does, so that's probably why he had it in there. But the plant we took had no buds on it, so we didn't actually have "marijuana" on us. I told them they could drug test me, but they didn't, ill probably be going to the police station to marrow to have them drug test me, so they know i don't smoke. When I woken up the next morning from the holding cell, a guy came and got me and I had to explain to him what happened. He said I will have a misdemeanor and someone will have to pay around $100 to get me out. I went back into the cell and fell asleep. Later he came back in and got me, saying they are going to release me because the prosecutor had to get everything together and he will call me soon. When they asked me what happened though, I lied and said we found the plant by these railroad tracks, which they didn't believe because me and my friend both said a different part of railroad tracks and they kept implying that we bought the plant from someone. When I finally got home, I talked it over with my parents and told them the truth, so my mom called them and said I was scared last night and wasn't being 100% honest and that I wanted to come back in and tell them the truth, and they said they will have me come in to marrow. Right now they are testing the plant or something to make sure it's a marijuana plant, so I was wondering if it is, when I go to court and stuff, what kind of trouble do you think I'll get in? This is my first time ever getting in trouble with the law. My parents think I will be on probation, have weekly drug tests, and be on community service. What do you guys think? If you read, It says I have never tried any drugs in my life, nor have I ever sold them.. I only stole the plant to make this kid mad I didn't like...  more

Resolved Question: 1. In plant tissue culture, so do we mutiply the plant. Do we take out one stem from the plant?

without the roots?But will this works because one plant has only one apical meristem right so stems alone would not be able to regenerate the whole plant rite? 2. How can we use leaves the form the entire plant?We must form the apical and root meristem first rite?How do we do this? 3. Do plants form more than one apical meristem and root meristem?Because if not, how can we use branches from the plant to grow the whole plant?Is every 'peak' of the branch apical meristem? 3. Is all cells of a plant totipotent for example the leaves, roots, stem? 4. Does the meristem bud in the plant pre-determined to be a specific part eg leaf or stem or flower?Or it must be induced to form one? 5. During mutliplication process, how do we identify which part of the plant is intended as 'one unit' to transfer it to another medium?I mean do the plant have like a defined 'fragment' u could used?I mean for example u cant just take the leaf itself rite?So do u need to take the stem and apical meristem rite, cause the roots can be induced?Or can take the roots together?  more

Resolved Question: How would N Korea go about making good on their threat to wipe the US off the planet?

http://ca.news.yahoo.com/s/capress/090624/world/as_koreas_nuclear Wed Jun 24, 9:16 AM By Hyung-Jin Kim, The Associated Press SEOUL, South Korea - North Korea threatened Wednesday to wipe the United States off the map as Washington and its allies watched for signs the regime will launch a series of missiles in the coming days With any luck Kim didn't pay his cable bill and couldn't watch this epidode of Fox "news" http://www.youtube.com/watch?v=WqnL2sATIl0 EMP a low tech no missile required weapon that would plunge the US back 300 yrs ---- 90 % death rates are predicted -- --- Well they likely missed Fox but lets all hope they didn't read this news clip that was written more as a warning than anything else ********************8 Nothing is easier than bombing a power plant on a coastline. There is no need to use a ballistic missile. Primitive means will do the job. The US has 103 operating nuclear power stations with onsite storage of a huge quantity of spent fuel rods and Japan has 53 operating atomic power stations. Japan has a stockpile of weapons-grade plutonium - enough to assemble more than 1,000 atomic bombs in a short period of time. South Korea has 20 operating nuclear power stations with onsite storage of a huge quantity of spent fuel rods. The detonation of sea-borne or undersea H-bombs planted on the three countries' continental shelves will trigger nuclear tsunamis with devastating consequences. ****************** The Pacific ocean --- is called the RING of FIRE because the plates are not stable --- and here we have a ship moving into the Pacific ocean and a STORY they might attack the non populated and of no strategic value at all Hawaii ***************************** The third possible attack, a high-altitude detonation of hydrogen bombs that would create a powerful electromagnetic pulse (EMP), would disrupt the communications and electrical infrastructure of the US, the whole of Japan, and South Korea. Many of the essential systems needed to survive war would be knocked out, as computers are instantly rendered malfunctioning or unusable. Military and communications systems such as radars, antennas, and missiles, government offices, would be put out of use, as would energy sources such as nuclear power stations and transport and communications systems including airports, airplanes, railways, cars and cell phones. ****************** Read it yourself http://www.atimes.com/atimes/Korea/KF12Dg01.html Why was it that China tied the hands of the US ---?

Resolved Question: Will this work better plus save money & educate our "youngings"?

You all remember Sheriff Joe Arpaio of Arizona , who painted the jail cells pink and made the inmates wear pink prison garb. Well......... SHERIFF JOE IS AT IT AGAIN! Oh, there's MUCH more to know about Sheriff Joe! Maricopa County was spending approx. $18 million dollars a year on stray animals, like cats and dogs. Sheriff Joe offered to take the department over, and the County Supervisors said okay. The animal shelters are now all staffed and operated by prisoners. They feed and care for the strays. Every animal in his care is taken out and walked twice daily. He now has prisoners who are experts in animal nutrition and behavior. They give great classes for anyone who'd like to adopt an animal. He has literally taken stray dogs off the street, given them to the care of prisoners, and had them place in dog shows. The best part? His budget for the entire department is now under $3 million. Teresa and I adopted a Weimaraner from a Maricopa County shelter two years ago. He was neutered, and current on all shots, in great health, and even had a microchip inserted the day we got him. Cost us $78. The prisoners get the benefit of about $0.28 an hour for working, but most would work for free, just to be out of their cells for the day. Most of his budget is for utilities, building maintenance, etc. He pays the prisoners out of the fees collected for adopted animals. I have long wondered when the rest of the country would take a look at the way he runs the jail system, and copy some of his ideas. He has a huge farm, donated to the county years ago, where inmates can work, and they grow most of their own fresh vegetables and food, doing all the work and harvesting by hand. He has a pretty good sized hog farm, which provides meat, and fertilizer. It fertilizes the Christmas tree nursery, where prisoners work, and you can buy a living Christmas tree for $6 - $8 for the Holidays, and plant it later. We have six trees in our yard from the Prison. Yup, he was reelected last year with 83% of the vote. Now he's in trouble with the ACLU again. He painted all his buses and vehicles with a mural, that has a special hotline phone number painted on it, where you can call and report suspected illegal aliens. Immigrations and Customs Enforcement wasn't doing enough in his eyes, so he had 40 deputies trained specifically for enforcing immigration laws, started up his hotline, and bought 4 new buses just for hauling folks back to the border He's kind of a 'Git-R Dun' kind of Sheriff. TO THOSE OF YOU NOT FAMILIAR WITH JOE ARPAIO HE IS THE MARICOPA ARIZONA COUNTY SHERIFF AND HE KEEPS GETTING ELECTED OVER AND OVER THIS IS ONE OF THE REASONS WHY: Sheriff Joe Arpaio (In Arizona ) who created the ' Tent City Jail': He has jail meals down to 40 cents a serving and charges the inmates for them. He stopped smoking and porno magazines in the jails. Took away their weights Cut off all but 'G' movies. He started chain gangs so the inmates could do free work on county and city projects. Then He Started Chain Gangs For Women So He Wouldn't Get Sued For Discrimination. He took away cable TV Until he found out there was A Federal Court Order that Required Cable TV For Jails So He Hooked Up The Cable TV Again Only Let In The Disney Channel And The Weather Channel. When asked why the weather channel He Replied, So They Will Know How Hot It's Gonna Be While They Are Working ON My Chain Gangs. He Cut Off Coffee Since It Has Zero Nutritional Value. When the inmates complained, he told them, 'This Isn't The Ritz/Carlton......If You Don't Like It, Don't Come Back.' More On The Arizona Sheriff: With Temperatures Being Even Hotter Than Usual In Phoenix (116 Degrees Just Set A New Record), the Associated Press Reports: About 2,000 Inmates Living In A Barbed-Wire-Surrounded Tent Encampment At The Maricopa County Jail Have Been Given Permission To Strip Down To Their Government-Issued Pink Boxer Shorts. On Wednesday, hundreds of men wearing boxers were either curled up on their bunk beds or chatted in the tents, which reached 138 Degrees Inside The Week Before. Many Were Also Swathed In Wet, Pink Towels As Sweat Collected On Their Chests And Dripped Down To Their PINK SOCKS. 'It Feels Like We Are In A Furnace,' Said James Zanzot, An Inmate Who Has Lived In The TENTS for 1 year. 'It's Inhumane.' Joe Arpaio, the tough-guy sheriff who created the tent city and long ago started making his prisoners wear pink, and eat bologna sandwiches, is not one bit sympathetic. He said Wednesday that he told all of the inmates: 'It's 120 Degrees In Iraq And Our Soldiers Are Living In Tents Too, And They Have To Wear Full Battle Gear, But They Didn't Commit Any Crimes,So Shut Your Mouths!' Way To Go, Sheriff! Maybe if all prisons were like this one there would be a lot less crime !!Q  more

Resolved Question: Believers of the unseen please explain this!?

Hi, I just joined about a month. I am a scientist. I know these things. For one thing I seen a lot of questions about mermaids, vampires, and fairies. Can you explain this than? vamps> How could vampires even exist, in natural habitat, the blood circulates the veins to their brain evenge. So if they somehow exist, their brains would have to be gone in which you could not live without a brain. And the exercise in their molecules will melt into their heart system making it not able to move and making it not able to beat in another meaning it in which is so be not able to live. The blood circulation inflates the heart and makes the blood come out frozen and than the cells die out. So if infected the world dies. In the teeth, venom will poison you. It will make them live for a less period of time just like any other poisonous things making it not able to move and making it not able to beat in another meaning it in which is so be not able to live. The blood circulation inflates the heart and makes the blood come out frozen and than the cells die out. So if infected the world dies. In the teeth, venom will poison. It will make them live for a less period of time just like any other poisonous things making it not able to move and making it not able to beat in another meaning it in which is so be not able to live.

It will make them live for a less period of time just like any other poisonous things. In the early life they would be born late because of the mother's adaption field to you. So how could they exist? Mermaids> Adapting to the enviorment under the sea, sea creatures must have gills, fins, and full fish. If it is part human it would not have any of that stuff. Plus it could not be a possible breed, human sperm cannot mix with fish sperm, infact any animal sperm. And infact we couldn't even mate with a fish, they just sperm in the water and the female fish suck it in with this one special body feature called Gulang. It mixes with it and breeds, human females cannot do this, the testicals must be producened into their virgina so it is very impossible for a mixed breed like that. They only thing that can mix with a fish is a fish, nothing more. And fish are oppisate blooded than us humans which makes it very impossible! Fairies> Fairies are fiction because the case of sarenoul is in magic. Causing diagnoses plants, humans, everything that has to do with life. Faries do not exist for these reasons: 1. The world would have died down from the magic introperuion already. 2. Magic makes a dent in matter which causes evolution making us unpowered. 3. Their blood circulates there own brain making them bleed out their breath so they would die. 4. If fairies existed god cannot because fairies would have been able to make earth on their own *I though do not believe in god myself* 5.

Resolved Question: why would a god judge and punish the objects of his own creation?

and why did he give us these useless body parts VOMERONASAL ORGAN A tiny pit on each side of the septum is lined with nonfunctioning chemoreceptors. They may be all that remains of a once extensive pheromone-detecting ability. EXTRINSIC EAR MUSCLES This trio of muscles most likely made it possible for prehominids to move their ears independently of their heads, as rabbits and dogs do. We still have them, which is why most people can learn to wiggle their ears. WISDOM TEETH Early humans had to chew a lot of plants to get enough calories to survive, making another row of molars helpful. Only about 5 percent of the population has a healthy set of these third molars. NECK RIB A set of cervical ribs—possibly leftovers from the age of reptiles—still appear in less than 1 percent of the population. They often cause nerve and artery problems. THIRD EYELID A common ancestor of birds and mammals may have had a membrane for protecting the eye and sweeping out debris. Humans retain only a tiny fold in the inner corner of the eye. DARWIN’S POINT A small folded point of skin toward the top of each ear is occasionally found in modern humans. It may be a remnant of a larger shape that helped focus distant sounds. SUBCLAVIUS MUSCLE This small muscle stretching under the shoulder from the first rib to the collarbone would be useful if humans still walked on all fours. Some people have one, some have none, and a few have two. PALMARIS MUSCLE This long, narrow muscle runs from the elbow to the wrist and is missing in 11 percent of modern humans. It may once have been important for hanging and climbing. Surgeons harvest it for reconstructive surgery. MALE NIPPLES Lactiferous ducts form well before testosterone causes sex differentiation in a fetus. Men have mammary tissue that can be stimulated to produce milk. ERECTOR PILI Bundles of smooth muscle fibers allow animals to puff up their fur for insulation or to intimidate others. Humans retain this ability (goose bumps are the indicator) but have obviously lost most of the fur. APPENDIX This narrow, muscular tube attached to the large intestine served as a special area to digest cellulose when the human diet consisted more of plant matter than animal protein. It also produces some white blood cells. Annually, more than 300,000 Americans have an appendectomy. BODY HAIR Brows help keep sweat from the eyes, and male facial hair may play a role in sexual selection, but apparently most of the hair left on the human body serves no function. PLANTARIS MUSCLE Often mistaken for a nerve by freshman medical students, the muscle was useful to other primates for grasping with their feet. It has disappeared altogether in 9 percent of the population. THIRTEENTH RIB Our closest cousins, chimpanzees and gorillas, have an extra set of ribs. Most of us have 12, but 8 percent of adults have the extras. MALE UTERUS A remnant of an undeveloped female reproductive organ hangs off the male prostate gland. FIFTH TOE Lesser apes use all their toes for grasping or clinging to branches. Humans need mainly the big toe for balance while walking upright. FEMALE VAS DEFERENS What might become sperm ducts in males become the epoophoron in females, a cluster of useless dead-end tubules near the ovaries. PYRAMIDALIS MUSCLE More than 20 percent of us lack this tiny, triangular pouchlike muscle that attaches to the pubic bone. It may be a relic from pouched marsupials. COCCYX These fused vertebrae are all that’s left of the tail that most mammals still use for balance and communication. Our hominid ancestors lost the need for a tail before they began walking upright. PARANASAL SINUSES The nasal sinuses of our early ancestors may have been lined with odor receptors that gave a heightened sense of smell, which aided survival. No one knows why we retain these perhaps troublesome mucus-lined cavities, except to make the head lighter and to warm and moisten the air we breathe.  more

Resolved Question: Evolution Questions Part 2:?

7. When, where, why, and how did life learn to reproduce itself? 8. With what did the first cell capable of sexual reproduction reproduce? 9. Why would any plant or animal want to reproduce more of its kind since this would only make more mouths to feed and decrease the chances of survival? (Does the individual have a drive to survive, or the species? How do you explain this?) 10. How can mutations (recombining of the genetic code) create any new, improved varieties? (Recombining English letters will never produce Chinese books.) 11. Is it possible that similarities in design between different animals prove a common Creator instead of a common ancestor? 12. Natural selection only works with the genetic information available and tends only to keep a species stable. How would you explain the increasing complexity in the genetic code that must have occurred if evolution were true?  more
