Comment LSD does have benefits (Score 1) 238

It can help reduce prison recidivism. See

The first studies on this were done in the 50's and 60's by Leary et. al. , who also pioneered the use of group therapy for prisoners.

It also seems to help alcoholics. If you google it up you will find that it has a huge potential for therapeutic use and Further research.

Despite growing evedence for useful applications of LSD it was banned in 1966 in a "Reefer Madness" like hysteria.

"Number of people times the years they stay equals the amount of food you need. Etc. p.p."

The amount of calories is probably well established, 2200 KCal/day per person give or take. But how do you design a fully self-contained environment which can provided the needed calories to support a (hopefully) growing population? How much would you need in terms of materials and energy to make such a system work?

In other words, you can't cheat gravity or the laws of thermodynamics. No one seems to listen, but my initial assessment is that the shear amount of energy required to launch a viable space colony is going to be prohibitive. I have never seen a detailed mass and energy budget for a colony. When exploring the New World you know how far to go, how many supplies to take with you, you had tools you could use to extract resources to support a colony etc. And even then colonies failed.

Thought experiment:
What is required to set up a viable colony? How many tons of food? How much equipment is required to build shelters? How much equipment must be sent up to extract needed resources? How many people must be sent up to have a viable gene pool? How much throw weight is required? How much energy? What is the overall costs in terms of global GDP?

We have a lot of people here, let's sketch some of this out. Simplifying assumption, that booster efficiency will increase by 25%.

Go ahead, give it a shot.. But in my case my gut tells me it will be huge.

Read "The Road to Wellville". It is set during the great breakfast cereal and processed food boom in the 1890's. A pattern followed by the great railroad buildout, the automobile boom of the late 1800s to early 1900's, the tech boom ofthe 50's, 70's, 80's, 90's, and later. The oil boom, cattle boom, etc. Nothing ever changes.
