In the future without fossil fuels how could we jump

Recommended Posts

Um... Parafin (Jet A1) is already a manufactured fuel...

Avgas will have a problem... but oil from coal allows 300 years worth of reserves at current usage, so it's a long term problem.

If you live longer than 300 years... there's always base, baloon jumps, paraglider jumps etc.

It's the year of the Pig.

Probably a combination of drugs and virtual reality equipment. You'd never know the difference, and you could experience anything you'd like...maybe ravish a top model after your skydive, then on to some ultra violence on the streets. It will be the biggest money maker in history, and very addictive for its participants.

Biodesel, ethanol, chemists and other scientists will find a way. for the short run though it is a great arguement for alternative fuels for cars, cars can run on ethanol, or biodesel now, jet fuel is more of a bitch. But our country seems to have no interiest in alternative fuels or fuel economy in anyway

Good Judgment comes from experience...a lot of experience comes from bad
judgment.

We just need to get energy into the plane, then get it into the prop. If the world runs out of energy, we will have a lot worse problems than not being able to skydive.

Someone mentioned space elevators. Well, one of the technologies to be used for space elevators is beaming (presumably as microwave) energy from the ground to the elevator climber. Jump airplanes fly nowhere near as high as a space elevator (several kilometers, vs. hundreds of thousand of kilometers), so this technology should work for that.

My suggestion is jump planes with energy reception cells (like solar cells) on the bottom, and only enough battery power to taxi around. This would be sweet because every load could be a hotload. (But I assume they would switch the prop off while we loaded - electric planes can do that.)

All fuels that I know of or heard of are somewhat carbon based. So, altho Parafin is from Crude Oil, parafin being Food Grade Wax's and such, Jet (don't know where you get A1) maybe you means Jet A...is actually from Crude Oil. Jet fuels are actually nothing more then K1...yes kerosene, and have a multitude of differant additives in the formula which when refined beyond just plane ol' K1 make differant "blends" of Jet fuels that are in use today. An example would be JP8, which is what the military are currently using A LOT of. Is nothing more then Jet A with 3 or 4 military only additives that have been blended at the refinery. Could be wrong, on some of this...but damm....been draggin that Tank around for a couple of years now, hauled a (hehe) shit load of JP8 and such to include NavGas, Crude, Gasoline, K1, K2, what we calls HHO (Home Heating Oil), many many many grades of wax including the stuff on them there dixie cups for drinking BEER, so could be wrong there....but I like the sling shot kinda thing meselfs
So, you bring your beer?

100% biodiesel is currently running around $3/gallon, and can be used in many turbine engines. And of course could be used in diesel recip engines for aircraft. Aircraft can be run on natural gas as well, and natural gas is pretty easy to synthesize from water and carbon dioxide.

Lot's of wasted methane on the plane shows up and vents out the door at around 7500 ft and up. At least at our DZ.

We could modify the engines to burn bunnies and kittens and hamsters. Plenty of those.

By then, some of the skygods will be so powerful that we could just ride the plane up on the force of their skill. And for those less skillful, we can ride up on their egos. And for the 100 jumps wonders, we could ride up on their BS.

Just brainstorming here

Fossil fuels are a subset of hydrocarbon fuels. Fat and oil contain medium-short hydrocarbons that can be extracted and used. That's what biodiesel is - vegetable oil with part of it removed. (Hi, Spencer. :)

In the FUTURE it is going to be cool.

I always thought it would be great to get those things that Bugs Bunny used to compete with Marvin the Martian.

You remember!!! It was a small round platform - enough for one person to stand on. And it had a lever. You push down on the lever until 15,000 ft, base jump, then freefly, then open, and land.

We don't need no stinkin fossil fuels.

My F350 truck doesn't burn fossile fuel even now. I use B100 biodiesel, and with the recent surge in petroleum prices, I'm not even paying much more than most folks. Like billvon says, it wouldn't take much effort to burn this stuff in a turbine, and you can look at www.deltahawkengines.com for some really cool recip engines that could burn it as well.

When we run low on petroleum, fuel prices will rise slightly. That's all. Don't worry, be happy.

I got it - We use solar cells to provide the power to separate water into hydrogen and oxygen, then use the hydrogen to provide our need for energy. There we go - Pretty much free fuel - Now we can't use hydrgen for everything, but by using it to power our biggest users (ground transportation and so forth) we free up enough of the remaining fossil stuff to use where technology and science hasn't discovered an alternative yet, which the most important is getting us to 14,000' as quickly as possible.

Personally, I'll just hitch a ride on the new space elevator, get off at 100k and say WEEEEEEEE!



Yeah, RIGHT ON!!!! B|B|B|

Can you say "8 minute freefall"?? :)

I read the lift to full alti (Orbit) would be "a few dollars"...
I'd just take 6k meters, that wouldn't hurt my arms too much...:)
