If the numbers are anywhere near right then they should easly recoop their money. Even if they fall short and have only 5000 sudents instead of 7000 then at $1400 each then they will earn 7 million dollars.
This technique would seem to operate on only a narrow range of wavelengths. Although it may work at visible wavelengths each lens is tuned to a single wavelength. Optical telescopes need ro refract at least a octive with one lens. This lens would need to be tuned to a single frequency. Not a problem for LASER light, monochromatic. No substtute for standard lenses for imaging.
Small WISPs do more to service rural areas than all the big cellular carriers combined. If the FCC wants these folks to have access to high speed Internet then quit selling all the spectrum to the highest bidder and make some of that "white Space" spectrum free and un-licensed.
A building of that height has lots of wireless options. Modern WISP gear can deliver 70Mbps+ with cheap hardware(~$100). Small antenna on roof + Cat5 cable to basement = lots of cheap bandwidth.
Then your stealing service. Comcast terms of service forbid reselling or distributing their service, even business class. Read your contract. Beside this isn't even close to enough bandwidth.
Layer three switches can deal with the rogue DHCP servers problem. Cisco 3550.
The Faster than light thing is a problem as no one knows how to make it work. Discovery one (2001 Space Odyssey) may be possible though. Sans Hal. Maybe Siri could substitute.
Most of the surge damage I have seen in the last several years is on things like phone lines and Ethernet. Long wires act like antennas and get high voltages induced onto them. Ethernet is especially sensitive. Surge protectors should located as close as possible to equipment being protected for maximum protection. Over the last several years I have lost more Ethernet ports on switches and equipment than anything else. Good Ethernet surge protectors at http://www.magicsurge.com/
Digital is best, but you will need to copy your data to newer media about every 10 years. Keep it stored on at least two different media types. Example: DVD, HD. Older magnetic media holds up well. I have some DC6250 tapes I recorded in 1992 that still read fine. My DAT tapes from around 2000 not so much. Almost all my 5.25 inch disks are also fine. 3.5 inch, mostly worthless. Of course these older media don't hold as much data. Lower media density is a significant part of why they are more reliable.
I currently store my data on LTO-2 tapes and DVD's. I keep old systems complete with there HD's.
Long term storage and preservation of digital data is a complex subject. I should know my wife wrote the book on the subject. E-ternally yours, the case for the creation of a reliable repository for the preservation of personal digital digital objects.
Not impressed. I can hand solder a circuit smaller and much cheaper on standard proto board with plated through holes. Done this many times with better results. For circuits I am going to make more than 1 or 2 of just download the free ExpressPCB program and for around $55 you can three boards.
This was the main online service I used for 10 years. Dumped it when AOL bought them. First connected with a manual 300 baud modem I built from spare parts. Still have the modem. Fun days.
I worked on a project called the Telesignature back in 1992. We used a pen tablet computer from Grid as the signing device. Several other companies followed suite in 1993. There was a pen computing convention in Boston that year. The only difference between these and tablets today was the pen. They looked and acted almost identical.
We got some copper clad steal Cat 5 cable a couple of years ago and had to throw it in the trash. Reason? We couldn't power any POE devices through more than about 50 feet of the stuff. It turns out to have 4 times the resistance per foot compared to copper.
I have at least a couple of times had trouble with equipment and had theories as to what the problem was only to be told by the vendors support team I was wrong. Long story short and lost customers later, turns out I was right. There support was actually harmful.
I have been running Linux for 15 years in our ISP where downtime was a big no no. Research on online forums provides quicker cheaper solutions that just about any support I have experienced.
Not possible. Randomly recreating just 100 characters of any work via random generation would take more time than from the big bang. Just the letters in the English language would be 26^100. A number larger than googol (10^100). The total number of elementary particles in the known universe is about 10 to the power of 80. If this space was packed solid with neutrons, so there was no empty space anywhere, there would be about 10 to the power of 128 particles in it.

I wonder how large a capacitor density could e made with this stuff?
This is silly. Cabs have been using twoway radios for decades.

If it were possible to make a profitable business of this that would be a very sad state of affairs.

Their answer is "because the math says so"?
I agree. These sound more like a different type of Field Effect Transistor than a vacuum tube. No tube, no heater, not even a vacuum.
Magnatrons are a type of vacuum tube. They have a heater, and cathode, and an anode. No glass to see these things through so you can't see them.

This will go over like a lead balloon. Filled with CO2.
The one network came out to drive out the many. I have to laugh at the thought of them even trying this.

Seems EFF got scared and took down the material on this matter from there website. None of the article links to EFF work.
