    The first few battery changes are covered by warranty and are included in the purchase price. Then after that you pay an arm and a leg.

    A guy on another forum is replacing the expensive battery in his electric Honda with a used one from a wreck. A few guys were fighting to get it.

    what batterys are in that honda? are they lead acid types? its still early days with battery vehicles. i used to work on them, mainly forklifts, golf carts, invalidity carts and milk floats(british thing)worked as part of a prototype team, i specialised in the actual build and wiring side as opposed to the major design. this was back when seperately exited motor controllers(american wording) first came in which involved controller reducing current in field and increasing speed, which meant you had major current to move the vehicle and once moving the current reduced as not to hold back the motor and getting good speed. an average milk float topped out at 15mph we had them at 60mph for fun. i worked mainly with 250-600amp and between 12-48vdc

    good work, while it lasted, all went to bulgaria

    The battery in the Honda is about 200V Ni-MH. I think they are AA size and are welded into groups.

    Melt some salt, then send electricity through the liquid. Make sure you are wearing a gas mask.....

    Not sure how to melt salt, but wouldn't it produce chlorine gas, which would be fatal. Pretty sure a simple gas mask would be of little help.

    Yes, it would produce large ammounts of chlorine. For security reasons(with all of the terrorism in this world), i will not say how to melt salt. If you really want to know, the melting temp. could probably be found in an encyclopedia. Oh, and, no, a simple gas mask would not work. It would also produce sulfer. I don't think a stove could get hot enough? Probably not. Oh well. Stoves are good for making pizza though. Hey! You should invite the gypsys over for pizza! Just kidding. :)

    People have been doing conversions with lead acid batteries, either flooded, gel, or VRLA. They seem to get like 25-75 miles, and that's with a lot of batteries. At current gas prices, if the batteries are maintained properly, the cost per mile is less than gas and that includes scheduled battery replacement costs. NiMH/NiCd can perform substantially better but they're quite expensive and more difficult to manage the charge state. Large li-ion cells are incredibly expensive and are generally not available to a home user. The facilities that can make them are maxed out on production and they go to this big EV projects, you won't find a price list on the internet and may need some sort of "in" with them to even get them to sell cells to you.

    http://www.evdl.org/help/ is an email list of people making EVs, usually by converting an existing vehicle.

    God, I didn't sayd that are all bad. In the vilages there is a perfect harmony between gypsies and romanian. The situation is bad only in cyties.
    Also, there is another family of gypsies right next to me and they are very decent peoples. Even more: we are friends and I leve them the key from my appartment. They even have jobs. All of them.

    The 'Science' announced that India made some advances in cold fusion.
    I think that we really need a viable alternative to the gasoline.

    To run a car on battery is the same as running it on gas.
    You need to recharge the battery. From where you take that power? From outlet (110/220V AC).
    When where this power came from? From the power plant. Which is running mainly on gas...

    We have lot of oil. Because of the Communists era we did not had so much cars. And we have plenty resources.
    But to give it to the Americans...
    ...come on.

    When we were under the communist regime, we looked at America as the biggest, nicest, brightest dream of freedom ever possible.
    Hew peoples who visited democratic countries bring back newspapers from America, or movies and we looked at them and we still did not believed that such freedom and wealth is possible.

    Now America is a bitter joke! A bunch of invaders in expensive cars ready to go to war, led by a 'democratic' president.

    Russians took Moldavia (20% of Romania) from us 45 years ago. When Russian Empire broke into pieces, we expected to receive Moldavia back but a communist decided to keep Moldavia for him and declared Moldavia as independent country.
    What Romanians did? Instead of starting war to take that region back, we were the first country who recognized that region as a new country.

    Since 101 BC when my ancestors attacked the Roman Empire we did not started a war or participated to an invasion. I have this reason to be proud of as Romanian, at least.


    -------------------------

    I did not start this thread to complain about our situation.
    Yes it very hard here when the average salary is 100$, when the communist influence is still powerful, when mafia (and gypsies) are riling by feast, and with a generation (our parents) brain washed by the old regime.
    However, it is our situation and gradually we deal with it.
    As I want to deal whit this bad cultural influence from the gypsy side that raised 10 years ago and started to badly darken our culture.

    It is easy to live in a rich country, even to own a personal car, and to point to a stranger to say "you are religious fanatic" or "you are racist" when you have no idea how is to live as Romanian in a country called Romania, suddenly filled with powerful arabic/gypsy/russians influences.

    -------------------------

    If some one still have an idea how to build a ‘manele silencer’ to regain the quiet around my personal space I will be grateful.
    If you still think I am the only one who have something with against manele then ask yourself why there are only movements against manele but non against rock, rap, opera, folk, etc, etc…

    Thanks to all who came with ideas.

    Sounds to me like it's easier, and safer for you to simply move out. With a country full of simpletons like that, it's no wonder I'm seeing more Romanian families immigrate to the US. That's fine, until they have a run in with an east coast/west coast gang banger! And those Romanian gypsies are small potatoes when compared to the actual activities of the Mafia... trust me on that one. I have a immigrant Romanian mechanic living near me and he loves it here. He has a decent paying job, bought a home in a nice neighborhood, big screen tv, fancy car, a playful dog, and just hooked up with an American woman that moved in with him and plans to marry. Within a couple of years she'll pack his suitcase and call him a cab. She'll get the house, car and the dog will prolly want to stay with her! He'll wander throughout the land distraught, no money, and heartbroken, living the life of a gypsy. :rolleyes:

    Our world is full of extremes. Some people have nearly everything and other people have nearly nothing.
    An average salary of 100$?? Per hour, week, month or year? Livestock animals that we eat are worth much more.

    Regarding the real problem (gypsies, stereo, etc), it should be possible to transmit a directional RF signal at their stereo at the proper frequency (which would depend on the specific stereo) that would be introduced in the amplification stage, and thus be heard out the speakers. As someone already posted, almost any piece of analog electronics is susceptible to this. Most simply aren't exposed to a high enough level of RF at the right frequency to exhibit the problem.

    Although this won't stop the noise, it could easily make it as annoying for them to hear as it is for you.

    So, you have a few groups of foreigners causing trouble in your country... We have all that, and from pretty much every country in the world. Not to mention a bunch of domestic-dumbasses. True, we usually have know idea why our government decides when to send our military in and get involved in other peoples wars (many are centuries old). But, when the terrorism was brought on our land, that's enough reason for me. So, we didn't find weapons of mass destruction in Iraq. Not really important, as they agreed to UN inspections, and refused to comply. Converting a muslem nation into a democracy? Now that is a joke, I give less than a year after we pull out the bulk of our troops, which should happen in 2-3 years, max. Bush will be out of office, and unless the democrats run somebody totally lame, like John Kerry... The republicans will be out of the White House. Personally, I think we should keep Iraq as American soil, it's the only way to prevent it from going back to the old style dictatorship. And we need a strong base in the middle east. There is a big reason why nobody uses nuclear weapons, and really need to make sure no one ever will.


    The stereo, the adjoining wall is concrete, figuring the standard 6" thick variety. It'll take one hell of a transmitter to cause any real problems, and I would definately not share these ideas with your neighbors, as they are going to get the same as the gypsies.

    Now, you wanted an EMF device... How about a Tesla Coil? High Freqency AC travels one the surface of conductors, instead of through them. Most insulation is ineffective. All you would need is to direct it through some pathway into the apartment and near the stereo. Concrete wall, usually mean metal conduit, water pipes, telephoe cables, TV antenna, cable TV, satelite, wet clothes line hanging out a window... Only need one thin wire running from the output of the Tesla Coil to whatever entry you can find. The only thing I'm sure I destoyed with mine, was a digital watch, and maybe my 386 computer...

    Yes. If they are infact that powerful, then it would be in your best interests to ask them nicely, or move out. Don't tempt fate!

    Although this is an old thread, I felt compelled to register as I was browsing it as I have similar issues.

    The OP has my deepest sympathies and I hope they managed to solve their problems?


    We have similar issues in the UK if you can believe it simply because of chavs and scrotes. Unfotunately there is a high amount of welfare supported people who just dont care in the area.

    Around here, even though we have noise disturbance laws, hell, even more laws than you can shake a stick at they are never enforced.

    We have had to put up with load rave music numerous times in numerous different house over the years. What started to tip me over the edge now though, is the music at 10am on a sunday morning didnt just shake the house, but did so to an extent a roof tile fell off and the sealant started to come out of the edges of the windows. At this sound level, earplugs dont help at all.


    In the past we have learnt people cant be civil as we've asked people at 4am "Could you turn your music down please as we need to get up for work in a couple of hours" to which people turn music up and vandalise your property.

    Unfortunately legal routes dont work over here and we have even been advised by environmental health that court action takes nearly two years and to report criminal dealings in the house. Quite astounding that the council encourages residents to lie about such things as prostitution just to get the police to consider attending.



    I would appreciate helpful advise on how to deal with this. Could I build some kind of feedback device that would cause a squealing feedback to show them how much loud obnoxious sounds hurt peoples ears?

    Invite yourself, and a few friends (neighbors) to the parties. Spill drinks, urinate any place other than the toilet, drop food on the floor, basically be the worst possible party guests. Leave stains on carpets and furniture, step in some dog excrement before entering the house. Try to be discrete, you'll eventually be asked to leave, and maybe not so politely, so it's best not doing stuff the host will know it was you, and deliberate. Basically, what you are going for, is a disgusting reminder, for the host to clean up, or pay to clean up/fix. Giving a party is always less fun the following day, and you always see how much respect and consideration give your home. Some people expect it, others only need one or two disasters to decide that it just isn't worth it.

    Don't know how effective 'squealing feedback' would be, since they might not realize it isn't 'music', considering the garbage people listen to these days. Seems like the 'artist' are trying for annoying and agitating, which is actually a principle of art (provoke an emotional response), just not a good thing.
