All my bags are packed
I'm ready to go
I'm standin' here outside your door
I hate to wake you up to say goodbye
But the dawn is breakin'
It's early morn
The taxi's waitin ' He's blowin' his horn
Already I'm so lonesome
I could die
Ironically the original was written by John Denver.
As with all so called neat inventions scaling up is the challenge and usually impossible
Get me on flight number 505 ...
John Denver, the former pilot with a thick logbook?
...and a full auxiliary tank.
aileron, elevator, rudder ...
Just thinking about the headline as I haven’t read the article yet.....reflecting on the ten cent balsa wood planes of yore (wonder how much they’d cost today?). They flew with no moving parts (unless one thinks of the horizontal stabilizers, and, or wings flying off, spinning to the ground when the assembled toy plane was tossed).
They flew, but they also crashed as parts flew off of them most of the time unless one took the step to glue them.
OK. Time to read the article.
I could see this for uses in quiet or small spaces cooling. Laptops, servers and other cramped electronics come to mind.
My home computer has a CPU fan that recently died. PC still works but I have to be careful regarding the temp. I would imagine that such a cooling would be able to last longer.
For one, the battery required to supply the necessary 40,000 volts the propulsion system requires would be massive, creating huge weight challenges that the design would need to overcome.
and just exactly WHY does it need to be battery powered?
a gas turbine as to make electricity would work jut as well
This is great! Now if we stretch a giant bungee cord from NYC to Boston a passenger version might have enough energy to take off. I think I need a grant...
It is the amp side of the equation that fattens it up. Like a hungry multitude at Thanksgiving.
a giant bungee cord from NYC to Boston ...
Maybe update that to a steam catapult, I think I saw a slightly used one from France up on ebay.
Or go whole hog, Electromagnetic.
If necessity is the mother of invention....why are so many unnecessary things invented?
They had an article about how you could make a flyer from tin foil and balsa wood and sewing needles, and power it with the output of a TV flyback transformer.
Perhaps MIT didn't have that issue in the library.
