Once you've gotten into the life raft that life vest has served
its purpose, now the challengs it so stay alive for weeks if
necessary.
So a water purification kit and a life vest made out of
waterproof, floating basic nutrition pellets could make a big
difference. Could make something like
malted milk balls so
they floated and are waterproof until you peeled off the
protective wrapping. That or candy bar shaped.
These would be crammed with as much nutrition as possible
and I'm guessing since you need about 1,000 calories a day to
survive, and using the malted milk ball candy as a model,
each being 140 calories, just a handful of these a day could
keep you alive, and a life vest could carry hundreds of hands
full.
This with a rudimentary fishing kit in one pocket and a water
purification device in the other your odds of surviving could
be greatly improved.
There's no reason these couldn't even be tasty and sweet like
a candy.

And the thing to consider, when you're jumping out of a
sinking boat or airplane, you don't have time to grab a lot
of
stuff and even if you did, you'd have to carry an additional
huge backpack full of food to get all the calories you could
get
from this thing. That would most definately add to your
peril, not subtract from it. |
|
| |
You've got a big bulky life jacket
on already, why not have it do the two most important jobs
necessary to save your life, short term and long term? Keep
you afloat till you get to your life raft, and alive till you get
rescued. |
|

Stitch this croissant into the lining [+]. |
|
| |
Good idea but I'm still sticking to bringing edible companions
as well. |
|
| |
[+] Even an inflatable life vest like they have on airplanes
could have a small amount of survival gear and a little food
attached. |

//Good idea but I'm still sticking to bringing

|
| |
^Heh, I don't remember seeing that one. |
|
| |
Don't you think that all the edible filling would likely attract bears? |
|
| |
I've heard there's good eating on a bear. |
|
| |
I think at the point you're so unlucky that you're on a
life raft in the middle of the ocean and get attacked
by a bear there's very little technology can do for
you. |
|
| |
"I've been on this life raft for 3 weeks, at least these
life jacket bars are delicious. Life's not that bad...
WHAT THE HELL!!!!!" RRROOOOAAAARRRRR! |
|
| |
Defeating the bear wasn't that big of a deal. Richard Parker
was, after all, famished. And now that he's satisfied, I'm a
little more safe... |

Maybe at the start, and maybe if the environment is
stressful. But otherwise the body quickly realizes what's up
and efficiency rises. The best strategy is really about
dragging out starvation, when you already have 10-40 days
to play with. |
|

I think a big part of nutrition is neglected.
Macronutrients/energy is at the forefront of people's
thinking, then it jumps off into micronutrients. The
micronutrients are named so for a reason, you really don't
need very much of them. Life at a basic level is just ion
gradients. You can tell, because dead things don't have
them. Most of your energy expenditure (at rest) is just
maintaining Na+/K+ separation across plasma membranes.
Doing work, is just deliberately de-separating those ions
and having to fix it repeatedly. Anyhow, my point is, that
just calories might not be the best way to delay starvation,
it's not very well researched as far as I can tell. A combined
Na/K/Ca/Mg pill might be a good way to go, especially as
lots of energy is expended by organs like the kidney trying
to hold onto those salts. |
|
| |
Perhaps the salts can be manipulated a little, Mg is the
default "Off" ion, having plenty might be a good way to
lower the energy expenditure floor. |
|
| |
All that is definitely waaaaay out of my area of expertise. |
|
| |
Presumably these would be designed by nutritionists to have all those life saving goodies, vitamins n stuff. |
|
| |
I'm curious, how often, in this age of satellite communications, GPS, etc do people get stranded at sea with nobody knowing where they are? Is this even a thing any more? |
|
| |
If you're an orphan off some third-world location without any
of that tech available, sure. |
|
| |
Most life rafts have GPS trackers these days, but I'm not sure
if they come with cellphone rechargers. Maybe that should be
a thing... |
|
| |
Yea, I'm not sure if the people who could afford this would
even need it. I dont' think there's ANY way to cross the
ocean
without massive amounts of redundant technologies
tracking
your location. |
|
| |
Found an interesting page on the subject. (link) |
|
| |
Now you could say that the reason there are so few stories
is because these are the ones who survived making it
notable. A better stastic might just be people lost at sea
every year that AREN'T saved. |
|
| |
Found that drowning is a major cause of death world wide.
Not just in the ocean, wells etc. See link. |

No one's gonna mention the issue with shelf life?
According to a cursory Google search, malted milk balls
have a shelf life of about 10 months properly stored at
room temperature. In a hot, humid environment typically
found at sea where such strandings seem to occur, I
imagine that shelf life will be rather shorter. Could cause
issues keeping edible ones in inventory. That, and if you
get even a small tear in one, suddenly you've got a
pest problem on board. |
|
| |
Maybe freeze-dried food packs such as what
astronauts eat? Doesn't help the water situation. |
|
| |
//malted milk balls have a shelf life of about 10

|
| |
I was only referring to the buoyancy of that
particular product. Plus malted milk balls probably
aren't the greatest survival food. This would be
designed to give the maximum survival benefit by
volume meeting the floatation, shelf life and
nutrition needs. |
