I think there is company that already sold the lands of mars to people just like the moon
wait till they fight it in court

Are we not Tier 1? Do we not collect and store energy from the sun?

We're not even close to Tier 1.
Quote:
Type I
"Technological level of a civilization that can harness all the energy that falls on a planet from its parent star (for Earth-Sun system, this value is close to 7x10**17 W) , which is quite higher than the amount that presently attained on earth, with energy consumption at ≈4×1019 erg/sec (4 × 1012 watts)." The astronomer Guillermo A. Lemarchand stated this as "A level near contemporary terrestrial civilization with an energy capability equivalent to the solar insolation on Earth, between 1016 and 1017 watts."

But at the rate which technology is improving, humans may reach Tier 1 before year 2100.

Whats your source, i saw conflicting info...

The Kardashev scale is a method of measuring a civilization's level of technological advancement, based on the amount of energy a civilization is able to use for communication.[1] The scale has three designated categories:

A Type I civilization – also called planetary civilization – can use and store energy which reaches its planet from the neighboring star.

We seem meet the standard by this definition.

Type I can use the equivalent of all the energy that lands on it from its neighboring star.

Inorganic rocket fuels used include:

Liquid oxygen + liquid hydrogen
Nitrogen tetroxide + hydrazine
Powdered oxidizers + powdered metals + inorganic binders
Zinc + sulfur powder



Not a carbon atom in sight, so no need to dig up dead dinosaurs algae.

The vast, vast majority of the propellant is liquid oxygen and liquid methane at a roughly 3.8 to 1 ratio.

Rocket exhaust is a blip next to every vehicle, factory, power generator etc in the world and will continue to be for a very long time. Elon's view for the future has electric vehicles and sustainable energy on a massive scale but rockets will be stuck on chemical engines for a long time unless we rewrite some of the laws of physics

This actually makes me very depressed in a way. I really want to go to mars. But I feel like it will be my grandchildren that will be the ones who are saving up to go, not me. frown.gif

However, that is not all there is to be considered. Looking at the geological timeline, we haven't had a major, extinction-level disaster in some time. Massive volcanic eruptions are overdue and statistically-wise, we should be getting hit by a medium to large space object at some point in the near future, and strictly historically-wise, we are at the edge of another ice age, it's what the clock says. Not to mention a single solar flare can fry the whole planet in matter of seconds, and can not be predicted or avoided.

But luck-based phenomenon aside, Fukushima is currently dumping 300 tons of highly radioactive water daily in the pacific ocean - the source of half the world's food. And humanity does not have the physical ability to limit this contamination for the next 10 years at least. By the time this is handled, the radiation background of the entire planet will have risen dramatically, due to this one accident alone. And this is all official data, not speculation. What of accidents yet to happen? What of accidents we do not know about? What of contaminants other than radiation? Sure, we have resources and space. But until we have viable means to handle radiation, contamination, unbalance in the ecosystems, major sea level rise, major temperature fluctuations, and fine ash clouds from either volcanic activity or collision, our best hope to protect our species from extinction, is to spread, to colonize. And considering how long it would take to establish a viable colony, we have no time to waste. 2cents.gif
That level of worry will make you go bald. The only way to protect us as a species is to stop breeding stupidity. We don't do that and we will never make a colony, much less a successful one.

By that definition, even a brainless plankton floating in the ocean is a Type 1 because it uses and stores energy from the sun. Doesn't take much for such a tiny amount of energy.

The correct definition is "can use and store ALL the energy that falls on the planet from the neighboring star". Which would mean creating a solar panel as big as the planet, or producing equivalent energy through other means (e.g. nuclear fusion on a mass scale). In that regard we're making big strides, but not quite there yet.

Keep in mind Type 2 is "harnessing ALL the energy of it's neighboring star" which is a colossal jump over Type 1.
