Short of a nuclear airplane, a solar airplane is the only heavier than air device I can think of that can stay aloft indefinitely. And we all know what a variety of interesting payloads that can be carried these days.
There are people all over the world with electrified homesteads that are completely off the grid using a combination of solar and wind. It's currently cheaper just to burn fuel and pay for electricity, but it can be done, and probably will be more so in the future.
Radio horizon extended and we can now all use 1/4 wave UHF antennas instead of asinine HF antennas and relying on ground wave+F layer ionospheric refraction.

I used to be a ham radio guy as well... assuming you are one. It sounds like it.
How about a tethered balloon repeater? With modern micro digital electronics, I'll bet a modest repeater wouldn't weigh much, and could be lofted to above 50,000' with relative ease.

I suppose it is due to my interest in commercial applications.Last edited by chanjyj; 07 May 13,, 23:41.

Tethered ballon repeaters can't be up indefinitely from my understanding of regulations (not to mention maintenance issues anyway). Furthermore right now in VK4 land where I'm temporarily residing, the Australian government is going to shoot me in the head if I start hoisting up balloon since I live in close proximity of BNE/YBBN. And.. some Blackhawks have been circling overhead recently.

Solar Impulse C, the aircraft exclusively powered by solar energy, has successfully landed at John F Kennedy International Airport in New York, completing the final stage of the journey across the US.
This aircraft has 12000 solar cells which will power four propellers and also charges the batteries which will be used in night. The solar impulse traveled 105 hours 41 minutes and 3,511 miles.
With the success of solar impulse we can expect more these kind of aircraft. I guess they will start with the single propeller aircraft like cessna 208, Aero AT3 and will reach Passenger jets like Boeing and Airbus .... but these needs more power than impulse .... lets see how it goes.

a perfect machine for drones and a perfect machine for targets,and imagine if it has the added ability of the fifth generation aircrafts ..with two cockpits and a small cabin ,than it shall be a havoc machine ,untraceable and a attacker,a spy a protector a detector a satellite any thing as you can use ,"n" no of wide options are open .

:slap:
1. How you imagine 12000 solar cells to be stealthy?
2. Adding more weight doesn't help, either. You want this thing to fly, right?
3. Why would you add 2 seats (assuming for pilots) to a drone?No such thing as a good tax - Churchill
To make mistakes is human. To blame someone else for your mistake, is strategic.
