Someone please forward this to Robert Zubrin. The penultimate
chapter of his *Entering Space*
("http://www.amazon.com/exec/obidos/ASIN/1585420360/"), "Meeting
ET", is one of number of flaws* in an otherwise mostly excellent
work**.
There, he jiggers the Drake Equation to show outrageous
values for components such as f-sub-ell on the righthand
side of the equation.
Russell
* - some other flaws, in brief:
1.) surprisingly unresearched typical statement about freezing
damage (the "cells expand and rupture" business) due to cryonic
suspension
2.) strawman arguments against feasibility of molecular
nanotechnology
3.) his embrace of Apollo-style government expenditures
- and government funding in general - to reach Mars
** - otherwise, I do highly recommend this book.
