Hi Neo...

I admire Dr. Kaku's energy and optimism and I hope he is right; that the Earth will transition from a Type 0 civilization, to a Type 1 civilization in about 100 years.
Ha ha, he jests. We will never reach the goal of Kardashev's Type 1 Civilisation, let alone even thinking about his Type II or III, (Types 0, IV and V are modern extensions).

And the so-called Warp drive of StarTrek along with 'Beam Me Up Scotty' matter transfer is pure fiction.
One can't accelerate much outside the range of 0.9G to 1.1G for half the distance we need to travel, inter-stellar wise, as we would need to decelerate at the same amount for the final half, and our closest stellar neighbour is about 4.3 light years away so any SAFE and RELIABLE journey would take, erm, a LONG time.
And we haven't even got to inter-galactic REALISTIC travel methods.

As for matter transfer, how can one guarantee EVERY particle in any one body will return to its exact position on rebuild?
If there were Types I, II or III civilisations we would be able to detect them as they would make themselves easily _visible_/_measurable_.

Climate change will put paid to any idea of colonising a barren planet like Mars as huge global conflicts will occur as military nations grab what quick and easy resources remain.

Storing all of the energy on the host planet is worlds away, (no pun), from reality as we have a core and mantle with as much energy as we would ever need, and yet we have not harnessed it in any way seriously. This alone could help combat climate change but......
Science, engineering and geo-physics are one thing, human nature is something else.

NAME
unitconv - simple energy and length units converter SYNOPSIS
unitconv [unit] value unitconv [unit] expression DESCRIPTION
unitconv is a simple energy and length units converter (written in Tcl). It is a utility program of xcrysden package (http://www.xcrys- den.org/). ENERGY UNITS
The following energy units are supported. The following list contain the "unit -- description" pairs, where the unit is to be specified on the command line. au -- Hartree ry -- Rydberg ev -- eV (electron volt) kjm -- kJ/mol kj -- kJ kcalm -- kcal/mol kcal -- kcal LENGTH UNITS
The following length units are supported (usage as above): angs -- Angstrom bohr -- Bohr radius m -- meter EXAMPLES
Convert a value from eV to other energy units: unitconv ev 3.25 Calculate an expression (values in Rydberg unit) and convert to other energy units (note that expression must be quoted): unitconv ry "-103.134567 - (-240.691356 - -2*17.543471)/2" In expression also mathematical functions available in tclsh can be used.
