    Sometimes I wish the researchers would compare what tech there is already out there and see what other solutions have been tried and field tested. I was fascinated with human powered watercraft. So far the fastest craft are of the hydrofoil designs. Any craft with a hull in the water such as racing shells and other fast effecient designs are no match for the speed and affeciency of hydrofoils which either have no positive displacement hull (which sink if forward motion is lost) and those designs which lift the hull out of the water as forward speed increases. Human power hull out of the water craft can run in the 15-20 mile/hour range.

    The current listed record in the article is 23.4 miles/hour for a human powered craft. Racing shells with a team of rowers run slower. How much I don't know. I could't quickly find speed listings for shell racing teams.

    Yea, lets download and stream content that I can no longer recieve free over the air. Who didn't see this a mile away. One home theatre system simply does not meet the diverse needs of a modern family. Mom wants the soap or gardening show, dad wants the big game or evening news, and the tweens want the latest sitcom such as friends or reality TV. In the end everyone finds their nitch online and the big set is religated to being a monitor for the cable box or game console. The lack of smaller sets with a tuner able to pick up over the air broadcasts and the ability to find good stuff online has made an end run over real time commercial laden over the air TV.

    Because you have the exact same problem with DLP sets, and a similar issue with LCD (backlight).

    It is true that DLP projectors have the same issue with lamp life. The article was comparing plasma and LCD which is why I didn't mention DLP sets. Both my laptops are older than 3 years old and get more than 3 hours of use per day. Neither has required a lamp replacement. The 1500 to 3K hour life of a high intensity projector bulb is considerably shorter than a typical cold cathode lamp in an LCD set.

    I'm suprised nobody has mentioned lamp life yet. It's a pricy part and has a short life.

    2. Video projectors have a very limited bulb life. In other words, if you are watching TV on your video projector about 3-4 hours every night, you would have to replace the light source bulb about once a year at 200-400 dollars a pop.

    It is their content if it copyrighted, but it is YOUR license - this is what everybobdy MUST understand if there is going to be any viable solution. Both sides must be protected, both sides must give a little.

    The sour point I have always had with the content industry is the total lack of anyway to replace the damaged media the content came on without buying a new license.

    Want an unscratched LP, buy a new one. Want to replace the cassette tape which warped in the car on a hot day, buy a new one. Want to move the content from your RCA video disks to a new format such as DVD?, buy a new one. Want to replace that broken VHS tape?, buy a new one. Where can I send my copy of Ventures Gold on 8 track for a replacement on CD without paying for a new lisence. This is one of the reasons the old Napster was accepted and justified by many who would never steal anything out of a store. Much of the Napster use was replacing lost and damaged media for content which the user had bought a valid lisence. Other things were then downloaded simply because the industry had been so shortsighted in replacing damaged or outdated medial Even today, they still have this fault. I have used the sneaker net in copyright violations in about the same measure the industry has failed to provide a way to enjoy my licenses for content on media that no longer functions. Am I a thief? Am I expecting too much for my media dollars?

    Time to end my rant. Remember DRM is supposed to prevent you from media shifting you content so you can play it in the future on new devices you may purchase. Take a lesson from your library of Plays for Sure content when you buy a Zune.

    Content of the future is DRM free. You Plays for Sure content will die like the content on my 8 track tapes. Your MP3 collection will transfer onto your new computer and devices.

    HF was a much higher frequency so it walked over the filters.

    Much inexpensive gear was never designed to survive in an RF field to save money. Even if the ham station is operating legaly, the problem arises from the RF envelope being detected by a non-linear component somewhere in the audio equipment. In the case of cheap PA gear, it is usualy the speaker wires or line in or microphone in lines that act as an antenna. This is rectified by a transistor junction, or slightly oxidised solder pin forming a diode which detects the RF envelope. This happens even when the ham radio equipment is 100% OK.

    I have had to fix some sound systems for churches and such as a mobile CB operatior would cruise by running either AM or SSB and would join the sermon in the church. Using a hand held CB walkie talkie, I could usualy find the path into the PA system by unplugging all the microphone cables, testing, unplugging the tape deck, testing, etc. Once the entry path is found it is usualy easly fixed by application of a small ferrite bead inside the amp on the signal line from the jack on the panel and adding a small shunt capacitor. Audio is generaly considered 20 HZ to 20,000 HZ. Putting in a filter that knocks off stuff above 50,000 HZ cuts the RF and doesn't impact the audio quaility.

    The worst case of cheap consumer junk are the stereo systems such as boom boxes and it's home ilk with absolutely no metal shielding of any kind in it. They are wide open to any and all RF that may happen to be in the air. Add clock radios to this bunch of offenders. A late night ham or CB'er and a bedside clock-radio is a recipe for a hate session with the local ham radio operator. It's easy to blame the ham operator, but hard to identify the CB'er with what looks like a car radio antenna stuck on their rain gutter just cross the fence.

    On the other hand a CB'er using a 500 watt linear amplifier run into clipping is a dirty mess to try to keep out of equipment. A lot of ham operators got the blame for illegal CB operation in the 1970's and 1980's. I know. I used to DF them. The worst offenders either ran a beam antenna and linear, or an antenna on the rain gutter or in the tree next to the house to hide it. The hidden antennas were the ones most likely to get into a flame war and use profanity, an activity almost never done by licensed ham operators.

    The low antenna tended to put a lot of RF into the next door sound system. The ham operator with a high gain directional antenna high on a tower did not tend to put much RF into the neighbors stuff.

    My favorite one is from many years ago. A ham radio operator moved into a new neighborhood and put up a tower and antenna in his back yard. The complaints came pouring in regarding to TV reception interferance problems, strange voices on the phone lines, voices on the intercom, etc. He replied to all complaints that he was sure his transmitter was not causing any of the problems and invited anyone to send a certified tech out to check for any out of band or excessive power transmission that could cause the problem.

    Nobody sent a technician to check his station. This did not settle the complaints and the FCC was called out due to the number of complaints. The FCC sent him a letter in response to the complaints and they required of him to have his transmitter certified by the manufacture.

    He wrote back and stated the transmitter was lost in shipping and he was waiting for the insurance to settle so he could purchase a replacement.

    Meanwhile he documented and filed all the complaints as existing conditions to the new location prior to beginning operation.

    How is this anything but FUD?

    I think it's more ignorance than FUD. The fear is they are putting the equivelant of a cell tower inside the classroom. Give me a break. The parents need a lesson on signal atrength verses distance verses ERP. Unless someone gets a clue and turns off the wireless inside the laptop computers so they don't search for a network, it's the transmitter on the desk that's much more likely to be an issue, not the access point stuck high on the wall.

    After they have an education, maybe they can learn to turn down the power so the signal can not be leached outside the classroom. They need a 25 foot radius of usable signal strength, not 200. Cut the power to about 5%. Now educate the teachers and parents that wavelengths in sunlight is deadly at high power. However at low power, such as in the shade of a tree, the chance of a fatal burn from a short sunlight exposure is much reduced is is generaly considered safe. No need for sunscreen to dash from the house to your car.
