Digest Number 1056

long time reader, first time writer. I know that one proposed method for
food in space is through algae. GMO algae would probably be best.

The congress of racial equality is holding a world conference on biotech and
gmo's @ the UN if any are interested, RSVP by 1/10 for UN security
clearance.

NASA trains astronauts to work on the white eleph -- I mean, the Space
Station by having them wear their pressure suits in a tank of water and try
to perform tasks with various tools. Not as easy as it sounds. I guess
that's the closest they can come here on Earth to simulating actual
conditions.

If you wanted a device that any DIYer could install
for fun, then probably the simplest thing to use would
be a computer controlled electric servo. This could
counter both the weight of the person, and moderate
the aceleration of gravity. So not only would you
weigh 1/6th your normal weht, but you'd only be
decelerated by 1/6th gravity when you jumped.

Impossible. ; )You could never advertise somthing lke
this as 'safe to use by kids'. Most playground
equipment doesn't come with 'adult supervision
required'. ;) Such a device could easily be as 'safe'
as a trapoline though.

You can't turn gravity off for pennies a minute. ;) A
cmbinations of pullies and weights SHOULD set you back
several hundred dollars.If it doesn't, it's probably
not safe. The electric-servo soltion would probably in
the multi $1000 range.

Consider that the higher the kid jumps in a pully
system, the more rope will be on the side of the
counter-weight. If you're not careful this increase in
the counter weight will accelerate the child towards
the roof.

Hello everyone!

First of all I will say you that I an new in this forum and I will present
myself. My name is Andrei Costea and I am an 18 years old student from
Romania.
I love very much the idea of space settlement and I really believe that who
will build a space sattlement will be the second Bill Gates in the world.
As a prove of my conviction I will say you that in 2004 I have won the grand
prize at the NASA Space Settlement Contest, and I saw that NASA is really
interested in these kind of devices.

I really appreciate your love for space settlement (maybe because I love
them too...) and I hope that we will make some constructive work in the
future...(nobody knows what future reserves us)

Sincerely,

Andrei Costea

I will send you this link with some photos:

And how do you think we could create the circadian cicle on a space
settlement...
I was thinking about lowering and ascending the parabolic mirrors ... but
there are a lot of disatvantages...

Welcome to the group. I like the way this list just keeps getting more
international all the time. Some of our discussions get into possible social
issues in the settlements, as well as the technical issues, and it's good to
have as many cultural perspectives as possible.
