    The feedhorn is full of acorns, put there by a raven over the Autumn months. It has really dampened the uplink signal to the satellite linking us to the servers in India so the lag has become so profound that the packets are all waiting in the queue until a free space opens up.
    You may also have a sticky mouse clicker. They don't make microswitches in China the way they used to make them in Japan

    I wonder why it wasn't called Sridar energy, why is it called Bloom ? There have been so many of these wonder inventions, they show a picture in a newspaper, everybody is supposed to say Wow ! and whistle through their teeth and its never seen or heard of again.

    My gawd people, sometimes I wonder where any of you learned to read.

    The fuel cells are made of ceramics which, like many modern day ceramics, are made from sand.

    The sand do NOT provide a source of energy.

    The cells are 50 percent efficient. They use natural gas to make electricity and waste half of it in the process.

    Big deal. All you get to do is pay the gas company the money you would have paid the electric company.

    In last Sunday's ( Feb 21, 2010 ) 60 Minutes TV program, 20 minutes of it were given to presenting the new fuel cells that are being produced and sold by Bloom Energy. Many large companys have purchased and are using these fuel cells, and these companys claim that they save a great amount of money by paying the gas company, instead of paying the electric company.

    I suppose also that producing one's own hydrogen gas from solar and wind is very dangerous as hydrogen leaks very easily since it is the smallest compound. Maybe a way could be found in the near future to safely store hydrogen gas, in order to convert this gas with fuel cells to electricity.

    Depends on where you are.
    Here in Iowa it would be reversed.
    The per kilowatt/hr rate for electricity from the local power company hasn't changed since 1995 and isn't expected to change. Natural gas is purchased on the open market and it's price is anything but steady. Last year when oil prices spiked at $140/bbl Natural gas was very expensive compared to electricity.

    Any technology that wastes half it's inputs can't be called "efficient".

    Building officials are meeting in back rooms with unions, utility executives, oil moguls, and EPA types. They will find a way to outlaw this product soon or at least limit it to utilities only. But not to worry for Bloom, his manufacturing plant and product will be welcomed in every other nation on earth except backward thinking USA and England.

    Has it struck a cord with anyone else that anytime an American or British invention shakes the world the government does everything within their power to stop it? This is why Japan makes thin film solar panels that sell in the USA for .98/watt but thanks to the government (protecting "us") it costs $10/watt to get it legally installed. The reality is there is a status quo. Government, law enforcement, the courts, everything in authority exists solely to keep the status quo. Innovation is crushed and life goes on under an increasing grip. Yes, Bloom will be forced overseas.

    NC5P , There just trying to prove that any / all alternatives do not work , or if the do , they cost too much .
    Like Nano Solar , one of 2 companies that were spouse to make the $.98 per watt panels avalable last yr. , but only sales to large commercial producers have been sold .

    The government and those evil big businesses are forcing Nano Solar to sell only to large commercial producers? Really? How about some proof?

    More than likely the $0.98/watt claim was bogus and large commercial producers are the only ones who can afford to produce panels with this technology.

    Look out for the black helicopters.

    During the Feb 21, 2010, 60 Minutes TV program about this post's topic of Bloom Energy's fuel cells, the main owner and leader of this company showed in his hand two tiny sample bottles of the two different special inks, that he stated were the primary secret for his new successful fuel cells. These two special inks are painted onto each of the two sides of the individual silicon fuel cell wafers, and then later these completed wafers are simply stacked together to complete the whole larger fuel cell assembly.

    Does anyone know anything about using and making fuel cell ink and making fuel cell silicon wafers ? If you do then maybe you could sell the instructions on EBAY of how to make your own fuel cells. But maybe someone now is already selling this on EBAY.
