I need to find out how much energy 1 average sized, (preferably british), nuclear power plant will produce comapred to wind farms and other renewable sources of energy. Or how many of each type of renewable energy station (e.g how many wind farms) will be needed to produce the power of one average nuclear plant. I need the answers by sunday night please! Thank you!

Obviously it is still just in testing stages. However, I am curious if this device could be incorporated in non conventional ways (ie. car and/or airplane), especially since it seems that a building in my home town is using a similar design in a skyscraper

In regards to perpetual motion, it really wasnt what I was thinking at all. So let me ask this for your brains to chew on.

Why is it animals, particularly ones in the sea/lakes have bumps on their surfaces (fins, trunk). Ordinarily I would presume a smooth suface would be aerodynamic, but that is not the case (curse vortices and fluid dynamics). I can think of many cases where adding (disturbances) actually makes products more aerodynamic (golf balls, and that design for a boat that uses two hulls with nothing in the center for example)

On a final note, I am continually disappointed by immediate dismissal of both new and old subjects, its not scientific in the least either.

Discuss!




T he 1973 oil embargo affected not just the United States but other oil-dependent nations. I lived in London at the time at an international youth hostel and worked for a British construction firm that built oil pipelines. At every petrol station, cars lined up for hours (as in the United States), but the English immediately cut their dependency through conservation in a way that Americans never did. The government stipulated that the people should go without heat for half of each week and without lights for the other half. Individuals and businesses that did not comply were fined heavily and written up in the next day’s news. These measures affected every home and workplace. I had urged our office supervisor to buy an electric typewriter “to increase productivity,” which she did, trading in the old manual. Suddenly we couldn’t use the new productive typewriter for half the week.
It was strange to enter a stately building, Her Majesty’s this or that, at midday and see workers toiling by candlelight or kerosene lamp. The subway reduced its hours of operation too. When my boyfriend and I would come out of a frigid theater or concert hall after some performance and find no subway running, we would walk the four or five miles home.
Without heat Londoners dressed warmly, but the winter nights in our student hostel were bitter. I slept fully clothed, including socks and a hat. On evenings with lights but no heat, we English-speakers would crowd the television room to watch the Watergate hearings. They were gripping and we were raucous, warming the room with our own hot air.
At the hostel, run by a Socialist Indian family, I shared with five other females a high-ceilinged room with three bunk-beds. One evening it was empty, so I pulled a straight-backed chair in front of the room’s single coin-operated space heater, rolled up a towel upon which to rest my feet, filled the heater with Italian 5 lira pieces (instead of the required 5 pence), and turned on the BBC. Chopin piano preludes wafted my way. Quickly I covered my legs with newspapers and wrapped a blanket around my shoulders. As long as that piano played and I had lira, I sat alone in the darkness, toasty in my paper tent, transported by the music—bliss amid scarcity.
Contrast that episode in 1973 with events two years ago in the United States, when the northeast regional power grid broke down.
Here in the city that never sleeps, New Yorkers reached for their candles, wind-up radios and flashlights. Several friends spent the night camped out on the floor where I live, just four flights up, friends whose other choices were to sleep in their offices or, after walking down 45 flights of stairs in total darkness, to spend hours more trying to reach their homes outside the city. Bus and train stations were overcrowded and off schedule.
Residents and businesses reached out to commuters, but some cab drivers charged outrageous fares (a practice London forbade in 1973). In high-rise buildings where a roof pump is required, the plumbing backed up, worsening by the day.
Unlike the long-term power outages caused by Hurricane Katrina (or the 1973 oil embargo), the power grid problem lasted only a few days. Still, it was striking to learn firsthand how even a brief loss of power causes the elderly, ailing and poor to suffer disproportionately. When I and thousands of other workers left the office for home on foot, we hastened by others who appeared barely able to walk along.
In a high-rise publicly subsidized housing complex near where I live, some elderly persons slept outside on park benches; without elevators they could not reach their apartments. They had no cell phones with which to make quick arrangements and no friends to take them in. Many went without prescription medicines, which brought discomfort to some, but posed serious health hazards for those with diabetes, respiratory illness and heart disease.
If all this upheaval takes place when oil is cut back or electricity is unavailable for a few days, what would an extended period of less oil mean day by day for the people in the United States? Hospitals have emergency generators and other critical backup procedures are in place, but are there truly any alternatives for the long-term, any short of conservation and new fuels?
Why are we still waiting for that new oil discovery in the Gulf (or Alaska or Venezuela) to spare us any inconvenience? Why aren’t we instead doing all we can personally and demanding from our government and businesses sweeping conservation measures, serious research into alternative sources of fuel and smaller, more efficient cars?
Thirty years separate these two sets of observations, yet the United States is still oil dependent and in that respect still sitting in the dark.
what are 3 possible problems that Americans migth face with an extended period of less oil an/or other limited resources?????




my plan for fuel in the U.S.?

Alright, if i was in congress, i would implement a bill that would eliminate ethanol subsidies and give it to petroleum based diesel (to get food prices down), also we would implement more nuclear, wind, and water turbine power plants for home power (to cut down on oil usage and stop coal usage for home power..), after that we would use coal to oil technology to get 50% of gasoline and 25% of diesel to be from coal ( i know its not "green", but with the home power coming from mostly "green" sources i feel that it would offset), we would also subsidize biodiesel to the point that we could blend bio to make B25 biodiesel for standard use. So, home power is from mostly "green" sources, transportation fuel (gas and diesel) is 50% MADE IN AMERICA!!!!! Like it? Don’t like it? Suggestions? let me know.
FedUp, Here is Coal to oil explained-http://en.wikipedia.org/wiki/Karrick_process#Gasoline To Dave J: While i do agree that we should all conserve as much as we can, look at countries like China and India where oil is booming, they use it like its freakin limitless and pollute 100 times what the U.S. does, and I have to Strongly disagree with you on one point, making all interstates tollways, how could the people who dont make alot of money make it to work? and dont they take enough of MY MONEY for federal income tax?

And to all who say that the Gov is run by oil companies and the like, the best thing to do is remember that the Gov is actually run by YOU!! YES YOU!! BY THE PEOPLE, FOR THE PEOPLE!!! The best way to make a change is to run those greedy people out of office by VOTING! Sorry for the rant, just irritates me how most of (not all) America’s youth cares more about freakin Xbox than who makes laws for them.




Can a home be built from scratch with enough solar panels and windmills to supply the family with all their modern energy needs including electric cars?




Electricity Production?

When They say power plants create say 40 Megawatts of power do they mean a day,

Come to think about it they have to right, i just read the news about Irans Nuclear plant creating 40 Megawatts, i just need to clear this up for myself as i get right annoyed when thinking about it,

If i use 10 kilowatts a day, a 100 other people do the same makin a 1000 Kilowatts, so the iranian nuclear power plant only powers 4000 homes a day, Pah!!!!

Also Fussion Nuclear power is a great interest at the moment, a hella lot better than wind turbines & solar Power




A friend and I that go to school together have been working on this project for over a year now, we have a working prototype of a generator created that does not require gas to produce electricity. We have done numerous presentations and people get all excited about it, but it has been very difficult to find funding to get this product to a market. It is almost as if people are scared of change, and do not want to try something new. We need help funding the final developments of this product to make it look commercial. It is currently made up of all sorts of gadgets, but it works!! You can power a computer, a refrigerator and all sorts of household appliances without ever plugging this thing in (and no its not solar or wind powered either).This has been tested by the engineering department at a university near by and is proven to work- we can show you. We can even make one on a larger scale to power a home, we just need financial support. Can anyone make any suggestions or lead us in the right direction?

we have a us patent. We had an attorney but we are just 2 college kids with little money, not many attorneys will work before being paid unless they share your dream and we have not found one who does just yet :)

I have sent letters and email to so many companies and R&D Firms, but still no response. I have even tried contacting politicians- but nothing yet :(

Sorry I can not share every detail of it online for confidentiality reasons. When ever we do a presentation, contracts must be signed, its a dirty world out there. But we are willing to meet with people who can possibly help us.




generator and alternator for wind turbine?

i’m building a electric wind turbine for a school project, and i have everything but the generator/alternator. does anyone know exactly what i need to generate electricity from a source that spins at various speeds, and where i can get those supplies? all i need is the electric stuff, i have everything else figured out. and don’t tell me its not possible, i’m basically done




He said when he was elected he was going to create American jobs. He said nothing about bailing out Fanny Mae and Fredie Mac. What he said he was going to do, was to build wind turbines, and create American jobs through doing that. I know, I heard him on the TV. I voted for the dummy, now he’s doing something completely different than what he promised. I understand, it sucks people have lost their jobs and are now loosing their homes. Yeah, that’s I was happy when I heard he was going to create American jobs, but, where are the jobs? What good does it do to hand out all of this money when people have no way of paying it back? What sense does it make? I thought we were going to get products back in the USA that actually say made in the USA on their labels? You know, American workers, jobs for Americans, where did that plan go?
Who was it who said, "Industry is the backbone of American Society?" I don’t remember, but it certainly makes sense. You can have all the education in the world, but if you are importing everything, your country will still loose. You have to have something tangible for trade. America was built on trade, and if we don’t have anything to offer, than no other countries need our goods.
What good is it for someone to be a doctor if no one can afford to pay them? What happens when our dollar no longer has any value at all?
We will go broke in no time. Oh wait, we’re already there, still, no jobs are being created.




Wind power, solar energy, and biomass fermentation, fossil fuel energy.

Many in the global warming camp warn daily that we must make changes now. That we must cut carbon emissions by 60, 70 and even some say 80% by 2050

http://april.stepitup2007.org/article.php?id=29

They mask this under the words, “its’ only 2 percent reduction per year.

So lets be honest ok? By 2010 just 2 years, what do we have to replace the 4% reduction in gas, oil or coal That is ready our ONLY source of electric power generation?
By 2015 we are now up to almost 15 % less elec being produced by coal, all the while power consumption has been increasing. What do we have and where will it is placed, with the fighting already taking place over the placement wind turbines, etc.

Please don’t waste anyone’s time talking solar. You could cover the whole southwest of the US with solar panels and still not have enough production to replace 3 percent let alone 15 pecent

So what are these green ‘supper ideals’, as well as where will they be built in order to reduce the emissions while at the same time Not sending us back 500 years or even worse. 500 years ago people where allowed to heat their homes and cook their food with coal or wood, you propose stopping that all together.
Well apparently either no one has a real answer or they are just sitting on it. Nuclear is not an option. We know the few loud mouths won’t allow it.

As far as solar, I have found nothing.
So by following Dana’s ideal, we would only need just a part of what they show, since there would be no place left to live right?




How to make electricity at home?

Hi,

I want to know how to make electricity at home. I have a science assignment to do and we need to make something that will make electricity. Anybody know how to make a windmill or a solar system? What would be the cheapest of these 2?




I am a substitute teacher on a limited income and we want to convert to solar and wind power if possible. The home was built in the 1920′s. Please only serious answers!




I’m planning on installing both solar panels and wind turbines at my house over the next few years hoping to be more energy efficient. But, being the high cost of it I’m planning on doing it gradually as the money comes available to me. I use on average over a 12 month period about 800 kWh of electricity a month. I also live in Michigan where the average amount of sun is only about 3.5 hours a day year long and that’s my reasoning for using both solar and wind. A grid tie inverter seems like it would be the most beneficial because it would eliminate the use of battery’s and I think it would maximize the efficiency of the system over its life time. I’m an industrial electrician so I think I can figure out most of the installation my self. Can anyone give me some advice on what would be a good starting off point because this is all new to me? I don’t have a problem working hard or doing more work to save some money as long as it wouldn’t effect the efficiency of the project.

Thank you for your time.
