Sanswire Demonstrates First Stratellite 192
Sterling D. Allan writes "Pure Energy Systems News (PESN) reports that GlobeTel Communications Corp. debuted their Sanswire Stratellite last week to over 300 people, including members of the media, personnel from the U.S. Department of Defense, U.S. and international commercial interests, as well as investors and shareholders. Stationed in the stratosphere, well above the jet stream, powered by film solar photovoltaic units, the device will make wireless communications available anywhere in the U.S., including on airline flights. One Stratellite will have a payload capacity of several thousand pounds and clear line-of-sight to approximately 300,000 square miles, an area roughly the size of Texas."

They've been hyping this for years, and while the telecom crash of the early 2000s kicked the chair out from under their business plans, they'd still be really really cool if they ever deployed the bloody things.
By the way, their PR mockup picture of the Stratellite [sanswire.com] looks amazingly like the whale in the Hitchhiker's Guide to the Galaxy.

(Actually, I suppose they could if they lauched it in North Dakota, but I'm less certain if they launched it from Kansas City.)
Still, at "several thousand pounds" it could carry a lot more than most satelites. And the lag time would be LOTS less. But I suspect a lower altitude would give better quality coverage. 5Km up would be nice for cities and counties, and would need to carry less equipment.

Traditionally, stratospheric balloon gas is at the same pressure as the surrounding air - the balloons are too lightweight to withstand any real pressure difference. When the helium expands during the day, some must be vented to stop the balloon from bursting. At night, ballast must be dropped to stop the balloon from falling. Thus the balloon can only stay up for a limited number of day/night cycles.

1. Regenerative power systems (the kind you can deplete and re-charge, whether that be solar cells and batteries, solar cells and closed-loop fuel cells, etc.) need to mature far beyond what is currently capable in order to make these craft work. Consider that the solar panels need to not only power all the essential equipment (radios, drive motors, wifi, etc.), but they also need to have enough excess to recharge batteries for night operations. For something very flat like the Stratellite(TM), this means they won't be able to operate too far north (or south) because the angle the airship makes with the sun will be too great - too few photons will be striking the cells. For the kinds of power densities they will need, this may mean not operating north of New York City, for example.
2. Now consider what happens at night. You have zero solar power - 100% comes from your storage bank (batteries, fuel cells, hyper-flywheels, etc). In the northern hemisphere at winter, you will need to plan on about 16-hours of power storage capacity before the sun gets high enough in the sky to start powering the ship AND recharge the batteries.
3. Assuming the nominal drag coefficient numbers others have talked about (~.05), an average airspeed of 40-knots, and assuming that the electric motors are 90% efficient at converting electricity to mechanical power, and that the propellers are 60% efficient at converting the mechanical power to useful work (thrust), this craft will need 45kW of power available 24-7 JUST FOR PROPULSION at 70,000 feet. 4. Assuming that their regenerative storage system has a power density of 100 Watt-hours per pound (which is optimistic), this equals 7,200 POUNDS OF POWER STORAGE REQUIRED! 5.
