Want to build a space elevator on Earth? Start with the moon

By Deborah Netburn
August 29, 2012, 6:18 p.m.Scientists have been dreaming of an elevator that will take us to outer space without the use of rockets for more than 50 years. 
Michael Laine has spent much of the last 11 years working on making that dream a reality.
He started his work at NASA as part of an Institute for Advanced Concepts research team in 2001, and then continued work on the space elevator as part of the privately held company LiftPort Group.
But in 2007 the company shut down. 
Now Laine and LiftPort are back, and they're trying to drum up publicity for a new round of space elevator work. Except this time, instead of putting a space elevator on Earth, they want to put one on the moon. 
It may seem counterintuitive, but apparently it is easier to build a space elevator for the moon, rather than the earth. Because the moon has no atmosphere, and less gravitational pull than Earth, the ribbon that stretches from the surface up into space doesn't need to be as strong, Mashable writes.
To generate some publicity for the project, Laine recently launched a Kickstarter campaign in the hopes of raising $8,000. (Yeah, right).
Deep in the page Laine admits that it will probably take at least $800 million to get a space elevator on the moon, but he is considering the Kickstarter campaign as a way to jump-start the project and build some excitement. 
As of Thursday the lunar elevator campaign has raised more than $35,000 and still has 14 days to go. 
That still gives you plenty of time to get in on a project that Laine says will "transform human civilization."
Contributions start at $1.

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
 
There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.

WARNING FROM RAEL: For those who don't use their intelligence at its
full capacity, the label "selected by RAEL" on some articles does not
mean that I agree with their content or support it. "Selected by RAEL"
means that I believe it is important for the people of this planet to
know about what people think or do, even when what they think or do is
completely stupid and against our philosophy. When I selected articles
in the past about stupid Christian fundamentalists in America praying
for rain, I am sure no Rael-Science reader was stupid enough to
believe that I was supporting praying to change the weather. So, when
I select articles which are in favor of drugs, anti-semitic,
anti-Jewish, racist, revisionist, or inciting hatred against any group
or religion, or any other stupid article, it does not mean that I
support them. It just means that it is important for all human beings
to know about them. Common sense, which is usually very good among our
readers, is good enough to understand that. When, like in the recent
articles on drug decriminalization, it is necessary to make it
clearer, I add a comment, which in this case was very clear: I support
decriminalizing all drugs, as it is stupid to throw depressed and sad
people (as only depressed and sad people use drugs) in prison and ruin
their life with a criminal record. That does not mean that there is
any change to the Message which says clearly that we must not use any
drug except for medical purposes. The same applies to the freedom of
expression which must be absolute. That does not mean again of course
that I agree with anti-Jews, antisemites, racists of any kind or
anti-Raelians. But by knowing your enemies or the enemies of your
values, you are better equipped to fight them. With love and respect
of course, and with the wonderful sentence of the French philosopher
Voltaire in mind: "I disapprove of what you say, but I will defend to
the death your right to say it".
