wot about h2o
I wonder if you could get condensation and split that to generate fuel. You wouldnt want to use hydrogen down here but up there its not likely to harm anyone - and its a lot lighter too!
A German-American company has successfully tested a prototype unmanned airship of weird and wonderful design. The so-called "Stratellite" craft is composed of gas-filled segments linked in a chain, so it can flex and bend with the wind. Here's a company flight-test vid (you need Flash and YouTube privileges to see it): …
US military has been experimenting with high altitude baloons for years.
Cargolifter AG had been developing long distance zeppelin -like cargo transports , before they ran out of money. (Just like the original zeppelin maker - hence the REALLY bad sponsorship deal)
Since it is the greenest way to fly, and since Iceland has plenty of hydrogen (Volcanoes,produce energy, crack H2O) but no efficient way to transport it, I think we might see a lot more of these in the future.(Unmanned, of course..lets hope no-one jams their gps)
You fargin' bastidge, you read my mind.
Brilliant bit of technology, I thought, but my brain can't stop it from looking like a goddamn' giant sperm.
On top of it, you spot one of these from the ground, flying at around 70k ft, and man, does it _ever_ start looking like a giant sperm. People really _will_ think we're being "invaded".
Oh, and I can't wait to see the first high-res orbital fotos from the ISS of one of these bad boys flying over water, while the crew and MCC joke about how it...
...ohh, never mind; the black trench, thanks.
Are we being politically correct on The Reg now?
So -this thing has a large white head and a flex-tail?
and it looks like a tadpole?
What were these chappies doing in Biology class?
It is without doubt or procrastination - a large Sperm cell.
None of you see the dreaded "planet eater" / doomsday machine that Captain Kirk bravely fought from his La-Z-Boy recliner many years ago? Hmm. Tadpole it is then.
If it really looked like a flying sperm cell, we surely would have been treated to a dozen or more Paris references by now. Tail's much too thick.
Why go to the expense of using large volumes of neutral buoyancy gas for fuel when you could use cheap, low volume, high energy density petrol or LNG and compress the excess expensive helium into a tank, replacing it by pumping air into a bladder, to keep the buoyancy neutral.
This is not new technology, it is analogous to the way submarines vary their buoyancy.
