Yeah but we all have defied the laws of aerodynamics from time to time.
All I need is 5 acres of solar cells on my mobility scooter and I can go to Jacksonville!
What I like is the two guys to the far right. Those wings must create some real lift!
At least the glide has a chance of being marketable. Wonder what it cost this earth worshiper to make this boondoggle.
Pray for America
This one is just ahead of the solar-powered flashlight on the practicality scale.
No, the solar-powered flashlight is a thoroughly practical, useful tool available on the free and open market from a wide variety of competing manufacturers and vendors.
This aircraft is an interesting experiment showing the possible viability of a light, long-duration, high altitude aircraft requiring no aerial refueling. While this experimental aircraft is manned, the concept would likely be most useful in a UAV.
A sense if humor is a valuable asset in life, I suggest you look into it.

This is progress? Sheesh.
Post #29 is not funny; it is merely stupid.
Sadly many Americans have been conditioned to mistake "stupid" for "funny" by several generations of self-so-called "comedians" whose stock in trade is mindless idiocy.
No matter.
Stupid is not funny.
Stupid is stupid.
Do at least try not to get stuck on stupid.
Get back to us when you have accomplished that.
Do at least try not to get stuck on the stupid idea that the only use for an aircraft is to move things from "point A" to "point B".
This is progress?
Yes, it is. Huge progress, in fact.
Believe me, you’ve given me an unintended lesson in stupidity.

To what?
Composites have been around for a while. Are these photovoltaic cells particularly light in weight? What’s revolutionary here? The whole exercise could have been drawn up on a chalkboard, and then erased, saving a lot of time and money.
This could have been done 40 years ago. But no one in the last 40 years wanted to spend their own money on a pointless endeavor. I suspect that government funding was involved in some way.
Nonsense.
Solar cells were neither light enough, nor efficient enough 40 years ago to lift their own weight much less the rest of aircraft. Likewise electric motors. Composites and thin-film polymers 40 years ago were nowhere near strong enough per weight to build an aircraft like this.
If you have to ask what's revolutionary about a lightweight, low maintenance, long duration aircraft which requires no refueling, nor requires fuel at its base ... you're not competent to be having this discussion.
Seriously ... with your attitude, the Bell X-1 would have been drawn on a chalkboard, then erased, saving a lot of money. It could have been done 40 years earlier, but no-one wanted to spend their own money on a pointless endeavour. I suspect government funding was involved in some way.
-—you’re not competent to be having this discussion.——
Well, I have an ME degree with a minor in EE, but you’re probably right, because I couldn’t care less.
From an engineering perspective, I find this very impressive:

IF that's true, the drivel you've been spouting is even less excusable than I had thought.
From an engineering perspective, I find this very impressive:
Yes, AlphaDog is seriously cool. I'd like to point out that "AlphaDog is actually the offspring of BigDog, an earlier, noisier, version with limited payload and operating range." Good thing nobody dismissed BigDog as something that should drawn up on a chalkboard, and then erased, saving a lot of time and money. I'd further like to point out that "AlphaDog ... was developed with funding from DARPA and the US Marine Corps" and "The company worked with engineers and scientists from Boston Dynamics, Bell Helicopter, AAI Corporation, Carnegie Mellon, the Jet Propulsion Laboratory and Woodward HRT".
Hmmmm .... I suspect that government funding was involved in some way.
