We're going to need to dig a lot more fiber and copper in the coming years to meet the exploding communications demand. Or we can just float a few blimps. Sanswire, a manufacturer of unmanned aerial vehicles, is working on a 525-foot helium- and fuel-gas-filled airship, the Stratellite, which would provide blanket broadband coverage from the tranquil heights of the stratosphere. Hovering at 65,000 feet, each blimp could provide phone, TV and high-speed Internet to an area about the size of Texas, without the lag times that have plagued satellite-based communications. Stratellites can even daisy-chain to link cities and rural areas across the country—all without a single new wire touching the ground.
