Perhaps you feel that you are being held back by past emotions or issues. What wasn't gone was the idea that airlines could save money by cutting back on meals and legroom. If even a regulated company has any hope of raising hundreds of millions of dollars on Wall Street to finance growth, it must prove itself creditworthy, by cutting costs and showing it can abide by shareholder values. What the airborne Internet will do is provide an infrastructure that can reach areas that don't have broadband cables and wires. For propulsion, it will use 14 brushless, 2-horsepower, direct-current electric motors. Unmanned electric mules - engine on the banks or over the water. This unique and interesting little motor owes its somewhat epigrammatic title to the resemblance of the drum to one of those sparred wheels turned by white mice, and to the amusing fact of its capacity for performing work having been originally computed in terms of a 'mouse-power.' The mill is turned by a stream of electricity flowing from the battery above described, and is, in fact, an electro-magnetic engine worked by the current.

You discuss nearly all the important components and steps, but it struck me that one broad issue is missing: how to get the power from the outside panels to the inside loads. For now, police robots are pretty rare -- there's little chance you'll bump into one the next time you're at Krispy Kreme -- but in a few decades, we might just see a rocket-shaped robot officer on wheels instructing us when to cross the street at the crosswalk. Click here to see how the Sky Station system works. Also, AeroVironment has teamed up with NASA on a solar-powered, unmanned plane that would work like the HALO network, and Sky Station International is planning a similar venture using blimps instead of planes. Sky Station believes it can have its first blimp deployed by 2002. Each blimp will have a life span of about five to 10 years. Each city in the HALO Network will be allotted three piloted Proteus planes. At least three companies are planning to provide high-speed wireless Internet connection by placing aircraft in fixed patterns over hundreds of cities. AeroVironment plans to launch its system within three years of receiving funding for the project.

AeroVironment plans to use these unmanned planes as the carrier to provide broadband Internet access. It would take a lot of time to provide universal access using cable or phone lines, just because of the time it takes to install the wires. The "last mile" refers to the fact that access to high-speed cables still depends on physical proximity, and that for this reason, not everyone who wants access can have it. Better connections can be made with a single solid wire, however single stranded wires are simpler to route via conduits. When it does, what is electric cable a single Helios airplane flying at 60,000 feet will cover a service area approximately 40 miles in diameter. A good insulator to cover the wire and prevent the electricity from leaking into the water was requisite for the success of a long submarine line. Cut the Green Wire! No, the Red Wire! The higher the gauge number, the smaller the wire. If you think your fuel gauge is playing mind games with you, you're right.

The Electronics International AV-17 voice annunciator sounds neat, but I think I can do a better job with about $50 worth of parts and a few billion hours of machine language programming. Robots are typically housed in tough, weather-resistant casing and rely on mobility systems that can handle steep slopes, rocky ground or small obstacles. The antenna array creates hundreds of virtual cells, like mobile-phone cells, on the ground to serve thousands of users. An 18-foot dish underneath the plane is responsible for reflecting high-speed data signals from a ground station to your computer. These pods also house the batteries, flight-control computers and data instrumentation. By combining the technological principles of radio, wireless networking, and modems, developers have created a way to send data over power lines and into homes at speeds between 500 kilobits and 3 megabits per second (equivalent to DSL and cable). Many Internet users are switching to cable modems and digital subscriber lines (DSLs) to increase their bandwidth.
