Our solar system has eight planets and Earth is one of the planet among these. All these planets revolve around the Sun in their own orbits. Each planet looks different when you see the satellite views of it. The planets not only are different from each in terms of composition & size but it looks different from each other in terms of colors as well.
For example – Mars looks red, Moon looks ashy grey, Saturn has a yellow appearance, Sun appears brilliant white and our Earth looks like a blue marble. The mother Earth is called a blue planet due to its blue color appearance from the outer surface but that's not it, we will go through in detail Why Earth is called Blue Planet.

Most of us are curious to know why the Earth is called a blue planet. A general statement about the blue appearance of Earth from outer surface is that 'The Earth has almost 70% water on its surface due to which it looks blue in color'.
Well, if you look at the images of Earth, most of its part looks blue which are the oceans present on Earth's surface, whereas some other part looks brown or green which is actually the continents and the poles of Earth looks like white caps due to ice.
However, the blue color of the planet may vary depending on the depth of the oceans. For example- If you take a look at the close picture of Earth's surface, it looks like light blue color at the area around the continents, whereas the deep areas of oceans look deep blue in color.
Do you know that the ocean looks blue due to the reflection of the sky because the sky is blue in color? The sky appears blue in color because our atmosphere disperses blue light (which is of shorter-wavelength) quite efficiently as compared to red or orange light (which is of longer-wavelength). This is why the sky appears blue in the day time as blue light with shorter wavelength gets scattered in all directions.
The oceans also look blue in color during day time due to the same reason. The ocean contains water in huge amount and the water molecules present in the ocean also absorb a certain wavelength of light. Water molecules also find easy to absorb blue light as it has shorter wavelengths, hence the ocean appears blue in color.
In fact, if you click a picture inside water, it will appear completely bluish in color. For this reason, the oceans and seas appear blue in color, hence the Earth is called a blue planet because almost 3/4th of Earth's surface is covered with oceans & seas.
Why Earth looks blue from space?
Well, a common factor we already discussed above is that the Earth looks blue from outer space due to oceans. Synthesia mac crack. This is not the only factor that affects the color of the Earth's surface but there are some other factors also that make the Earth appear like a blue dot.
From outer space, the Earth looks like a blue ball. These are the factors that play an important role in the blue color of Earth-
- Water content on Earth's surface
The Earth has extremely hot red heat under its crust and the top outer surface is covered with water. The Earth's surface has many oceans and seas starting from the Arctic Ocean to the Southern Ocean.
These oceans & seas cover almost 70% of Earth's surface and the remaining 30% is covered with land. It means that almost 70% of Earth's surface appears blue from outer space & the leftover 30% looks greenish-brownish. This is the reason why Earth looks blue from outer space.
- The color of the water content
As of now, we had known that the Earth appears blue from outer space but now we will discuss why water is blue in color. Water has the property of absorbing most of the colors of the light spectrum present in the Earth's atmosphere.
The oceanic water on Earth's surface radiates blue in the spectrum that gives it the blue color. If the oceans have been radiating any other color (for example red) then the Earth's surface would look alike that color like red. This is why the continents do not look blue for the same reason, it looks brown or green.
- Dispersing in the ambiance
The composition of Earth's atmosphere mainly contains two gases- nitrogen & oxygen. The molecules of these two gases present in the atmosphere absorb, disperse and radiate various lights. The lights with longer wavelengths such as red, yellow, orange etc. do not get affected much by the atmospheric gases & does not get absorbed as well.
Chrome download 64 bit full. On the other hand, the blue light (with a shorter wavelength) gets absorbed and scattered by the atmospheric gases which create the blue sky we see daily. This blue light cannot be seen from outer space but plays an important role in the blue appearance of the Earth's surface. Similarly, during the night the atmospheric gases could not connect with sunlight, hence the sky looks black in color.
- Few other contradictions
If you look at the Earth's surface from outer space it will look blue due to the presence of sunlight. On the other hand, if you are orbiting the Earth, it will appear black in some parts where it is experiencing night. The reason for appearing the Earth black is the absence of sunlight during the night, whereas during the night the stars look much brighter and the lands look dark blue due to artificial sources of lights.

Technology Overview
Blue Planet's new biomimetic carbon capture and mineralization technology utilizes several patented scientific breakthoughs.
Products
Blue Planet uses it's patented Liquid Condensed Phase (LCP™) Technology to convert CO2 into high-value CarbonMix™ building and highway materials.
Projects
Blue Planet is developing projects both at sources of carbon dioxide like industrial plants, and utilizing it's carbon-sequestered aggregates in concrete projects.
Sustainability
Blue carbon is captured naturally by marine ecosystems to build coral reefs. Blue Planet uses a similar mineralization process to convert CO2 into carbon negative building materials.
Unique, Efficient & Low-cost Carbon Capture Method
Blue Planet's technology uses CO2 as a raw material for making carbonate rocks. The carbonate rocks produced are used in place of natural limestone rock mined from quarries, which is the principal component of concrete. CO2 from flue gas is converted to carbonate (or CO3=) by contacting CO2 containing gas with a water-based capture solutions. This differentiates Blue Planet from most CO2 capture methods because the captured CO2 does not require a purification step, which is an energy and capital intensive process. As a result Blue Planet's capture method is extremely efficient, and results in a lower cost than traditional methods of CO2 capture.

Synthetic Limestone Coating
The carbonated solutions formed from the captured CO2 are used to form a carbonate mineral coating over a nucleus or substrate. The carbonate minerals form a synthetic limestone coating. This permanently sequesters the captured CO2 as CO3= in the carbonate minerals comprising the limestone coating. The aggregate can be produced in different sizes, ranging from sand-sized to gravel-sized.
To reform our capture solution, it is exposed to a 'Geomass' which is our term for common rock waste and/or industrial waste materials that contain available alkalinity, which recharges the capture solution, and metal ions such as calcium, magnesium, and iron. When the 'spent' capture solution reacts with the Geomass, reforming it, these metal ions are released and combined with the carbonate solution to form the carbonate mineral coating.

Livequartz 2 1 1 – simple image editor. Aggregates
Blue Planet carbon sequestration plants produce coarse and fine aggregate made from sequestered CO2 utilizing the carbon mineralization process. The use of Blue Planet aggregate is the most effective way to achieve carbon neutral – or even carbon negative – concrete. Standard concrete by comparison, typically comprises the largest CO2 footprint in a building or infrastructure project. In strength, performance and cost, Blue Planet CO2-Sequesterd Aggregate is equivalent to that of standard quarried aggregates.
CO2-Sequesterd Aggregate
The coating consists of synthetic limestone [CaCO3] crystallized on the surface of recycled aggregate, giving it a smoothened surface finish. Each ton of CO2-sequestered limestone traps 440 kilograms of carbon dioxide, preventing it from accumulating in the atmosphere.
Upcycled Aggregate
Upcycled Aggregate is a by-product of demolished and returned concrete that has been through a calcium extraction process for Blue Planet's carbon dioxide sequestered limestone. This aggregate is useful in most concrete mixes, and is well indurated and harder than virgin aggregates due to the uniform process of Blue Planet's reformation step. While our Upcycled Aggregate does not directly sequester CO2, it offers significant benefit compared to virgin aggregate by adding recycled content value, and the avoidance of CO2 related to mining and transportation.
San Francisco International Airport
Blue Planet's limestone-coated light weight aggregate was specified in Interim Boarding Area B at San Francisco International Airport where it was included in the concrete poured in 2016 by Central Concrete. Concrete testing showed that Blue Planet's concrete met all necessary specifications. Photographs show the placement of Blue Planet's concrete at SFO.
A typical cubic yard of concrete has a carbon footprint of approximately 600 lbs. of embodied CO2 mainly from manufacturing the portland cement component of the cubic yard. The current approach to lowing this carbon footprint is reducing the amount of portland cement in the mix, usually with an SCM (supplementary cementitious material like fly ash). But this approach is limited to only reducing the carbon footprint, and only by about 50% or 300 lbs per cubic yard (CarbonStar ratings of 600 and 300 respectively).
Using Blue Planet products the carbon footprint of a cubic yard of concrete can be not just reduced, but the cubic yard of concrete can become carbon-negative by two specific methods: First, by replacing conventional fine and coarse aggregate (sand & gravel) with Blue Planet synthetic limestone aggregate, which is 44% by mass CO2 now converted to a permanent crystalline solid state in CaCO3, the entire carbon footprint of the portland cement can be completely off-set and can further be more than offset, taking the carbon footprint into the negative carbon range. For instance a typical cubic yard of concrete may have 3000 lb.s of aggregate; if it is all Blue Planet synthetic limestone, then 44% of it is sequestered CO2 (from a power plant or other industrial plant), or 1320 lbs of CO2 is offset.
Second, If the portland cement in the mix originates from a cement kiln where Blue Planet has captured the CO2, then the typical 600 lb. carbon footprint of the portland cement in the mix doesn't come into the calculation. Thus the total offset is 1320 lb.s industrial or atmospheric CO2 sequestered in aggregate + 600 lb.s captured from the production of portland cement, totaling 1320 + 600 = 1920 lb.s CO2 offset, or nearly one ton CO2 (2000 lb.s) captured and incorporated per cubic yard of concrete.
Precise values are determined applying LifeCycle Carbon Analyses (LCA), that incorporate the auxiliary load carbon footprint of Blue Planet's processes and transportation at specific plant locations and CO2 emission industry-specific types. Additionally, specific comparative mix designs can be simply and quantitatively compared using the CarbonStar rating which plainly shows the consequences of different proportions of aggregate and cement of the mix designs of interest. For example, the CarbonStar rating of the carbon-negative mix design discussed above is -1920, or about one ton carbon negative per cubic yard. In practice, this means that every cubic yard of this concrete which is places contains the 1920 lb.s of CO2 that would have otherwise entered Earth's atmosphere https://free-athome.mystrikingly.com/blog/best-stl-editor-for-3d-printing.
SUSTAINABILITY
Magnitude of CO2 Sequestered Aggregate Impact
Approximately 50 billion tons (50 Gigatons) of rock is mined every year worldwide for use in concrete, asphalt, and road base. This market is growing at a rate around 8% per year. 70% of the aggregate used in concrete is already limestone. Limestone (CaCO3) is 44% by mass CO2. Every ton of limestone contains 440 Kg of CO2, now transformed in CO3 (carbonate) in a crystalline state. 50 billion tons for limestone contains 22 billion tons of CO2.
Balance of Aggregate Demand and Anthropogenic CO2
We believe human (anthropogenic) contributions to Earth's atmospheric CO2 levels is about 35 billion (35 Gigatones) per annum, and growing. More than half of this CO2 (22 billon tons) could be consumed from the production of limestone aggregate used in place of the currently mined aggregate. This approach would also save enormous transportation costs and carbon footprint.
Government Procurement Power
Most aggregate on a worldwide basis is purchased by governments, or for government-funded projects. Governments have the procurement power to specify carbon-sequestered rock in construction projects, providing what may be the strongest lever we have world-wide to prevent CO2 from entering Earth's atmosphere. This approach is a truly global one in that both rich and poor countries alike purchase rock by funding infrastructure projects every year.
Existing Infrastructure
With the exception of water, aggregate is the most transported material on Earth. Creating aggregate from CO2 is one of the few highly impactful, globally sustainable means to significantly address climate change, since a new infrastructure is not required. The transportation and product delivery infrastructure for delivering Blue Planet's carbon sequestered aggregate is already in place in every country and at every site in the world that is producing concrete, asphalt and road base.
Circular Economy and Concrete Upcycling
On a mass basis, concrete is the most recycled material on Earth. Typically if it is not landfilled, it is broken up and recycled for a low value use – such as a road base. Blue Planet uses this recycled concrete in its remediation process as a means of obtaining calcium and alkalinity. The remaining by-product is the original sand and gravel used in the concrete, which would normally be limited to low value applications. But because Blue Planet denudes it of its weakened crushed components, it is now upcycled to the equivalent regular aggregate.
Comparative CO2 Capture Process
Blue Planet 2 Trailer
Blue Planet converts CO2 to CO3 after capture, but at no point do we purify the CO2. That's because purification of CO2 requires vast amounts of energy, taking away from our objective of a net reduction in CO2. This sets Blue Planet apart from other CO2 capture companies, where the goal is to concentrate the CO2 in to a pure form so it can be pressurized and liquefied for use in geological sequestration.

CarbonStar Embodied Energy Rating System
Blue Planet's Government Affairs and Built Environment teams are working with global leaders in the green building industry to develop a simple way to communicate the carbon footprint associated with concrete. The CarbonStar rating is a metric-based on the embodied mass of CO2 in a unit of concrete. Of the three components in concrete – water, cement and aggregate – cement is the most significant contributor to CO2 emissions. If a cubic yard of concrete uses 600 lbs of cement, its CarbonStar rating is 600. The goal is to get the CarbonStar rating as low (or negative) as possible. One approach to lowering the CarbonStar rating for a cubic yard of concrete is to replace traditional aggregate with Blue Planet aggregate. The difference being that Blue Planet aggregate contains sequestered CO2, which when used in place of traditional aggregate, reduces CO2 in concrete.
