VENUS -projects and ideas for terraforming this world into a New Earth

The planet Venus has the same gravity as Earth, it is twice as close to the Sun as we are.

After the Venusian terraforming there would be two perfectly habitable areas from the start, namely the polar areas that are permanently lit by the sun, ie there we have an eternal day (if instead of ozone we had a gas from floating micro-bubbles with hydrogen that would generate a fluorescent refraction-reflection effect from the light side of the planet to the dark side of it considering that the Venusian day and night last for a whole year). about 243 Earth

On Venus, a day lasts about 243 Earth-days. That's longer than it takes the planet to complete an orbit around the Sun. So, a Venusian year actually spans just 225 Earth-days

Until we reach the level set out above, we will have to get rid of the dense Venusian atmosphere of carbon dioxide, which is currently at approx. 100 atmospheres pressure and approx. + 400-500 degrees Celsius.

The whole thing could be done by a single intelligent gas with floating micro-bubbles, gas shield that would become opaque to light and thus keep the planet Venus cold and very cold.

The cooling of the planet will also be done by a stationary shadow, a screen solar satellite located quite close to the Sun and perfectly synchronized with the Venusian position and motion in orbit, so the remaining carbon dioxide could solidify and deposit on the Venusian surface in large caps just like on Mars but not in the habitable polar zones but on the rest of the planet where it will be an eternal evening.

This solution could be applied singularly as a complete solution.

Carbon dioxide becomes and remains solid at -50 / -70 C and a pressure of over 5 atm, so the entire Venusian atmosphere could be reduced to carbon snow and would remain a nitrogen atmosphere.

We would quickly get a planet like Mars but with an atmospheric pressure similar to the terrestrial one and made up mainly of nitrogen and some oxygen, and the polar areas would be warm and habitable.

Water would be obtained by deep drilling.

Carbon Dioxide Emissions and Global Warming can start the process of desertification of the Planet Earth as Sahara was Jungle a millennium ago

Sahara Jungle 10 000 years ago

A recent study brings us extremely worrying news: in 50 years, rising temperatures will dramatically affect the lives of more than three billion people.

10,000 years ago, the Sahara Desert was one of the wettest areas on Earth

This situation is proving extremely unfortunate, especially if we take into account the problems related to food security for these people whose agricultural land will become useless, notes Futurism.

Fortunately, if we can say so, this is one of the darkest scenarios, but it starts from the reality we live in: insufficient actions related to stopping global warming and the continuous increase of carbon dioxide emissions globally.

The study points out that on every inhabited continent there will be a series of regions whose conditions will be extremely harsh and will not allow human life, among these regions are: Brazil, North Africa or India. This increase in temperatures will lead to the expansion of the temperate climate to more northern regions: Canada or even the Arctic.

The direct consequence of these changes in environmental conditions will be the increase in the number of climate refugees, who will have to move from regions close to the equator to the north and south of the planet in search of less affected regions.

Scientists convert carbon dioxide to create electricity

While the human race will always leave its carbon footprint on the Earth, it must continue to find ways to lessen the impact of its fossil fuel consumption.

"Carbon capture" technologies -- chemically trapping carbon dioxide before it is released into the atmosphere -- is one approach. In a recent study, Cornell University researchers disclose a novel method for capturing the greenhouse gas and converting it to a useful product -- while producing electrical energy.

System to convert carbon dioxide into electricity and hydrogen source: Computing

Lynden Archer, the James A. Friend Family Distinguished Professor of Engineering, and doctoral student Wajdi Al Sadat have developed an oxygen-assisted aluminum/carbon dioxide power cell that uses electrochemical reactions to both sequester the carbon dioxide and produce electricity.

Their paper, "The O2-assisted Al/CO2 electrochemical cell: A system for CO2 capture/conversion and electric power generation," was published July 20 in Science Advances.


The group's proposed cell would use aluminum as the anode and mixed streams of carbon dioxide and oxygen as the active ingredients of the cathode. The electrochemical reactions between the anode and the cathode would sequester the carbon dioxide into carbon-rich compounds while also producing electricity and a valuable oxalate as a byproduct.

In most current carbon-capture models, the carbon is captured in fluids or solids, which are then heated or depressurized to release the carbon dioxide. The concentrated gas must then be compressed and transported to industries able to reuse it, or sequestered underground. The findings in the study represent a possible paradigm shift, Archer said.

"The fact that we've designed a carbon capture technology that also generates electricity is, in and of itself, important," he said. "One of the roadblocks to adopting current carbon dioxide capture technology in electric power plants is that the regeneration of the fluids used for capturing carbon dioxide utilize as much as 25 percent of the energy output of the plant. This seriously limits commercial viability of such technology. Additionally, the captured carbon dioxide must be transported to sites where it can be sequestered or reused, which requires new infrastructure."

The group reported that their electrochemical cell generated 13 ampere hours per gram of porous carbon (as the cathode) at a discharge potential of around 1.4 volts. The energy produced by the cell is comparable to that produced by the highest energy-density battery systems.

Another key aspect of their findings, Archer says, is in the generation of superoxide intermediates, which are formed when the dioxide is reduced at the cathode. The superoxide reacts with the normally inert carbon dioxide, forming a carbon-carbon oxalate that is widely used in many industries, including pharmaceutical, fiber and metal smelting.

"A process able to convert carbon dioxide into a more reactive molecule such as an oxalate that contains two carbons opens up a cascade of reaction processes that can be used to synthesize a variety of products," Archer said, noting that the configuration of the electrochemical cell will be dependent on the product one chooses to make from the oxalate.

Al Sadat, who worked on onboard carbon capture vehicles at Saudi Aramco, said this technology in not limited to power-plant applications. "It fits really well with onboard capture in vehicles," he said, "especially if you think of an internal combustion engine and an auxiliary system that relies on electrical power."

He said aluminum is the perfect anode for this cell, as it is plentiful, safer than other high-energy density metals and lower in cost than other potential materials (lithium, sodium) while having comparable energy density to lithium. He added that many aluminum plants are already incorporating some sort of power-generation facility into their operations, so this technology could assist in both power generation and reducing carbon emissions.


A current drawback of this technology is that the electrolyte -- the liquid connecting the anode to the cathode -- is extremely sensitive to water. Ongoing work is addressing the performance of electrochemical systems and the use of electrolytes that are less water-sensitive.
