The dirty side effects of Green Energy

The change in climate continues to be one of the most critical dangers to the honour of life on planet Earth. Fortunately, most of the equipment required in stopping global warming exist already. The use of recyclable energy resources is spreading in the West; however, the electric vehicles production, solar cells and wind turbines require to be scaled up. To source every power from recyclables by the year 2050, citizens need about 1 billion other electric vehicles and an additional of a 30-fold boost in solar photovoltaic capability.

However, as the West economies address the climate emergency, another disaster is deteriorating elsewhere. Building all those cars, panels and turbines calls for resources like copper, cobalt and lithium, which just like fossils are mined from the ground. However, unlike relics, most raw materials from renewable energy come excessively from developing nations. 

In the past years, cobalt extracting in the Democratic Republic of Congo has dropped into the community consciousness, starting with Amnesty International report of 2016 that unveiled child labour at the nation’s nonindustrial mining sites, which supply cobalt that makes smartphones and other gadgets all over the world. 

The abuses of human rights and environmental poverty in places such as Congo do not augur well for the West’s conversion to sustainable power, which will extend the green power materials demand. Some sceptics even quote such unpleasant effects of recyclable energy production to disagree against any conversion to green power. Like in the latest, widely condemned Michael Moore-produced Planet of the Humans documentary that also promotes the falsehood that developing recyclable technology devours as many fossils as burning them.

Scientific researches end that even the materials production required making wind and solar technology results in far few emissions compared to oil or coal. Benjamin Sovacool, who is the energy policy professor at the University of Sussex, stated that fossils are downright worse at harming the environment, and even community compared to renewables. Benjamin’s research also approximates that minerals are way too expensive and harmful environment-wise compared to recyclables in the long run.

The question of how to source minerals and metals ethically still lingers to be a genuine and an urgent one. Researchers, policymakers and leaders of the mining industry are currently debating on how to guarantee the migration to green power does not worsen social and environmental problems in a different place. One of the suggestions is to enhance the tracking of mining deliver chains.


Africa50 helps to develop Solar Energy in Egypt through Fund.

Thirty Global infrastructure builders were involved in this activity; they all came together to input their resources and skills into the big solar park in Egypt, which is ranked the biggest globally. The success of having investors in the Africa50 is evident to be from the African Development Bank. Africa50 is a self-regulating infrastructure funding company that has the aim of great transformative programs that are majorly in the section of transport and energy. The investment organization ensures the development of Africa by venturing and putting their money in bankable activities. They have the high aim of increasing the capital in public and the private sector in African countries by ensuring development both in the government and the private sector in the nation. 

An example of such a project the Africa50 has ventured into is Egypt’s 1.5 GW solar park in the Aswan desert. Egypt has an incredible possibility to strive with a solar-powered system; this has been for so many years and has brought onboard hungry investors. They are interested in investing in it. The disadvantage of high priced solar plants caused the government institutions to advocate for climate charged fossil fuels, which accumulates over 90% of the power generated.

Now that the costs of solar components are cheaper, solar power has turned out to be available. In the year 2017, the Africa50 collaborated with the investors Norfund and Scatec solar to get to a 32 utility-scale solar energy pumps to reach a total of 390 MW. The development of the Benban program, which aims at giving clean energy to over a thousand households will assist Egypt to complete their targets of producing  20% of its energy power from its clean energy sources by the year 2022. It has put Egypt in the spotlight to play the role of the most significant solar player in Africa.

The Africa50 project has shown its ability to deliver by the solar energy project in Egypt. It has proved that it can act as a link between the government institutions and the private section to ensure that there is a success to many projects to assist Africa’s infrastructure gap. The Africa50 is under consideration to be among the special helpers to the Benban park. They confirmed a pay of 25 % investment pay to the funding of construction and to ensure the success of the Egyptian solar project.  


Tower Extension Assembly tests are on to evaluate the suitability of the James Webb Space Telescope

Technicians are evaluating the efficiency of the Jame Webb Space Telescope before its launch into space for vital observations. The test was to analyze the Deployable Tower Assembly. This tower hosts gold mirrors and scientific equipment for space observations. The tower creates a gap between the telescope and the cooling systems so that the telescope can experience its working conditions. 

This telescope’s design ensures it can locate trails of infrared light or heat energy from astronomical objects in space, spanning a long distance from the telescope. Various extensions are underway on the telescope to ensure that it stays active directionally. Additionally, simulations are on to create the space environment and test the capabilities of the telescope to collect astronomical data. The main challenge is to create a simulation of zero gravity.

The Webb deployment systems leader Alphonso Stewart highlights that the DTA is giving noticeable results. He applauds the replication of the practice test to the theoretical principles. Stewart adds that it is possible to integrate the interfaces and associations between the equipment and the data transfer section.

The DTA serves several purposes among them, containing the Webb Telescope on Ariane 5 rocket and cooling the observatory. It is commendable to witness scientists design a fitting container for the Webb Telescope. The DTA allows the Webb to fold out its components like the mirrors and sun shields once the spacecraft is in space.

Stewart says that further tests are essential to ensure that the Webb collects extensive data for analysis and discernment of space characteristics. These tests also evaluate the control and communication systems between the spacecraft and the earth-based control center. The firm intends to conduct more tests for precision and accuracy purposes.

However, the shelter-in-place measures lead to a reduction in the number of professionals conducting these tests on-site. This challenge is attributable to the novel coronavirus pandemic. Nevertheless, there seems to be a glimmer of hope three months later with most of the employees of NASA and Northrop Grumman resuming work.

In conclusion, the James Webb Space Telescope is historic equipment. Its launch will save astronomers the trouble of arguing with satellite companies to adjust their near-earth-orbit satellites so they can view astronomical objects. Webb will come back with answers to most arguably challenging space and cosmic questions. Scientists and astronomers are all hands on deck to uncover space mysteries. The Webb will help minimize propaganda concerning space.


China initiates satellite for ocean monitoring

A Chinese civilian-operated oceanography satellite was set up in orbit following its launch on a Long March 2C spaceship on Wednesday, joining a precursor deployed in 2018 to watch the color and temperatures of the ocean.

Chinese engineers also started modifications to the Long March 2C’s freight fairing to assist the structure in maintaining its shape during its descending to Earth, the recent in a series of tests that could assist in leading to the revival and reuse of the future Chinese spacecraft.

The Long March 2C spacecraft launched with the Haiyang 1D oceanography satellite from the Space Center of Taiyuan situated in northern  Shanxi province in China on Wednesday at 1831 GMT (2:31 p.m. EDT).

The launch happened on Thursday at 2:31 a.m. Beijing time. Propelled by hydrazine engines, the two-stage launcher lifted off from Taiyuan with a thrust of more than 600,000 pounds and arced toward the south to take the Haiyang 1D spaceship to a polar orbit disposed of 98.4 degrees towards the equator.

The tracking data of the United States of America military showed that the satellite positioned into an orbit, which is about 480 miles (775 kilometers) above the Earth’s surface, close enough to the prelaunch objective. The China officials announced that the launch was successful. 

The Chinese Academy of Launch Vehicle Technology (CALT), stated that engineers brought changes to the Long March 2C’s payload fairing for the sendoff.  The CALT is the foremost state-owned launch vehicle manufacturer of China. 

Few minutes after the sendoff and after ejecting from the launcher, the payload shroud on Chinese spacecraft typically detaches and falls on the ground automatically. Designed by lightweight, thin walls to lessen the mass, the two-piece payload fairing could lose its shape during fall back. 

According to CALT, the Chinese bureaucrats added an X-shaped ray to strengthen the fairing structure to protect the nose cone from damage during the fall back to the Earth’s surface. Engineers also set up an optional fiber sensor on the fairing to help in measuring strain, stress, and other structures during the fall back through the atmosphere. 

The satellite will monitor the ocean floor, a measurement that assists scientists in tracking pollution and natural constituents of the ocean, such as chlorophyll. Haiyang 1D will also help in measuring the temperatures on the sea surfaces, image coastal waters, and also identify signals coming from ships. The measurements will then be used in farming operations, weather forecasting, and water conservation.


Within two days China makes two launches and lifts four satellites to space

China had gained the momentum of conducting rocket launches just recently when the Demo-2 operation, which was going down on the American soil in Florida, China, was also not left out. China made two successful rocket launch, and this was happening around the same time when the Demo-2 rocket was blasting off in the International Space Station

China launched two latest automation-demonstrating satellites at around 4.13 p.m. EDT, and the satellites blasted off fruitfully into the orbit onboard a Long March-11, which took off from the space station in the south-western part of China. And this was per the media outlet CCTV of China.

One of the leading designers of Long March rockets, Peng Kunya, highlighted that that was the first time the Long March-11 was blasted off from the Xichang Satellite space station which verified its flexibility to dissimilar launching spots.

A couple of hours later, China blasted off another satellite, which was in duo form, from the north-western part of the country. The rocket which was launched was called the Long March- 2D and it took off from the Jiuquan space station at around 4.53 a.m.EDT

Gaofen-9, which is among the satellites launched in Jiuqan space station, is a remote citizen place detecting satellite which can take photo images, It has a resolution of about a meter. With all these fantastic features, it can be used to survey land, conduct urban planning, and conducting estimations on crop yields, and aid in disaster management as well.

The HEAD Aerospace Technology Company that is located in Beijing has constructed another satellite dubbed as HEAD-4, it has been made in a manner that it gives a hand to the Internet of Things, and this allows permits connected gadgets to dispatch and receive data from the orbit, this vivid satellite will be utilized on ships and airplanes.

China had great success in 2019 when it is nearing to end, at other times, blasting off rockets hours separately at dissimilar space stations. The speed of spaceflights gradually decreased when the year 2020 commenced, and this was brought about by the outbreak of the COVID-19.

From February, however, the country got back to its spaceflights missions with maintaining the social distancing from one person to another to reduce and prevent the spread from one person to another. At the onset of May, China blasted off two other satellites to display its assistance towards the Internet of Things services, which can help to dispatch and receive information from the space. 


Sounds heard by scientists as Mercury-bound Bepi-Colombo passed our planet

According to a report released on 5 May by European Space Agency, Bepi-Colombo stored five eerie sound recordings as it soared past our world at a speed of 2.159 miles.

The flyby operation of European-Japanese that took place on 10 April aided in the tightening of the orbit belonging to the spaceship around the solar, the tightening will help to bring the spacecraft near its destination: Mercury. This planet is least explored in the solar system by space explorers. 

European Space Agency stated that the Bepi-Colombo would be able to amass data to enhance a better understanding of Mercury. The operation consists of two orbiters, namely, the Mercury Planetary Orbiter, whose work is to explore the surface of the Earth. The other orbiter is Mercury Magnetospheric Orbiter (MMO), whose task is to provide a better view of the Earth’s magnetosphere. Earth’s magnetosphere is the magnetic bubble produced by the planet that protects its surface from radiations produced by the sun and cosmos. 

During the process, the ship was able to use two out of eleven constituents present aboard the MPO-the Italian Spring Accelerometer (ISA) and its magnetometer (MPO-MAG). On the other hand, the ship commenced on several passes, and the exploring device made a close journey towards our planet as it slid into the Earth’s shadow. Also, it listened to the magnetic fields of the Earth carefully before getting out of the Earth’s atmosphere. 

The approach of the Bepi-Colombo on Earth

The Italian Spring Accelerometer was in a position to capture 8 hours measurement from the board of Bepi-Colombo after soaring between 256,393 kilometers to 129,488 kilometers of distance above our planet. Since the accelerometer was searching for frequencies that are lower to hear by the human ear, the recordings had to freeze into one minute of sound, before undergoing some adjustments at (INAF). According to Carmelo Magnafico, one of the INAF team associates, he stated that the vibrations that are as a result of both external and internal factors are conveyed to the accelerometer. 

When the Bepi-Colombo slipped into the Earth’s shadow, it lost the sight of Earth for a 34-minute clip. The recording ends when the orbiter from the Earth’s sphere. 

The Bepi-Colombo noted the sound produced when the magnetosphere of our planet crashes with the solar wind. When the Bepi-Colombo passes through the outer surface of the turbulent magnetosphere, there’s the production of sound as well as it passes through the magnetopause, a point where Earth’s magnetic fields start to spread. 


Blockchain supporting most of Renewable Energy Evolution of Germany

As Germany closes down all of its coal and nuclear-based power production, Blockchain is supporting most of its recyclable energy platforms.

With Germany targeting at decommissioning all nuclear energy generation in the nation by the year 2022 and every coal-based stations by the year 2038, countless disparate recyclable power producers of different sizes are raising to meet demand. Dispersed ledger technology is increasingly supporting the architecture for most systems created by the nation’s ground-breaking recyclable energy providers. 

Cointelegraph talked to Richard Lohwasser, who is the CEO and co-founder of Lition Energie, a Greentech startup based in Berlin. It started a Blockchain-based market permitting customers to decide between multiple power producers to talk about DLT usage across the developing energy sector of Germany.

A Blockchain-energized power platform 

Following its founding in late 2017, Lition was registered as an energy provider by German supervisory bodies in March of the following year and started offering power to consumers the next month. The syndicate started a large-scale marketing action in the summer of 2019, approximating that it would have consumers in not less than 1000 cities by winter. 

Lition’s associates comprise of International software producers Microsoft, PowerCloud, and SAP, as well as local companies SudwestStrom and N26. In contrast, its shareholders include European family offices investing through an adaptable note. 

Lition runs a green power marketplace that links households directly with sovereign green energy plants of their choice. The firm also strategizes on starting to provide solar panels later in the current month of June. The platform includes a proof-of-stake, second-layer solution designed on top of Ethereum (ETH). Lition offers a feature of data deletion and transacting fees of 0.001 USD.

Richard Lohwasser stated that it is tough to say at that juncture that they are amid the Energiewende, a German word describing this energy change. The possible penalties of the current plan are unfolding at the moment. Currently, power production is changing to a more local or regional level.

Richard stated that there is a lucid call for decentralization in the power infrastructure on a countrywide level. He added that for countless years, they were used to having just a few centralized power producers. Consequently, the entire infrastructure was moderately centralized and not at all appropriate for a potent mix that comprises a massive quantity of wind, biomass, solar and other sorts of power production that have moderately small kilowatt per power output unit.


The collision of the Blue Nile concerning power production

Egypt and Ethiopia are in a crash on the Blue Nile Renaissance Dam, the biggest hydraulic dam in Africa, over the Grand Ethiopian Renaissance Dam (GERD). Both nations have increased the tension and pushed the international political scene to the fore. The outcome was evident as Ethiopia departed from peace talks mediated by the United States at the end of February. Ethiopia initially asked for more period for discussion, but later issued a declaration that the US pressured them to make an agreement which was not in their investment. The Egyptians, who had hoped that the American-mediated talks would soon be resolved, were plummeted by Ethiopia’s discontinuation. 

The Arab League consequently gave funding to the conflict by seeking Ethiopia to honour Egypt’s sovereignty from over the Nile. The GERD’s reserves will maintain approximately 74bn cubic meters of water at a rate comparable a year and a half of the stream of the Blue Nile, a big sticking point among Ethiopia and Egypt. The move is equally significant. For seven years, Ethiopia needs to replenish the reservoirs while Egypt needs the duration in Ethiopia to be 12-21 years longer. The clock is running out for a deal with Ethiopia, which is preparing to begin refilling the reservoirs in July 2020. 

Throughout the uncompromising dispute, Ethiopia and Egypt must have proper preparation to create substantive changes to prevent a disastrous destabilization. The GERD mission, launched in 2011, is $5bn and will change Ethiopia. Upon fulfilment, approximately 16,000 GW of energy production is yet to change the power industry. Today, only 44% of families in Ethiopia have full rights to power, one quarter of whom depend on off-grid services.

Egypt, a wasteland country which depends mainly on the Nile for its natural water requirements, is seriously challenged by GERD regardless of its advantages offered to Ethiopia. Ethiopia, unlike Egypt and Sudan, has constrained water and cultivable land and is highly improbable to utilize the river for water-based farming. Nevertheless, it is committed to developing its hydropower production capability in the Nile Basin. As some analysts claim that 84 percent of the Nile freshwater that enters Egypt comes from Ethiopia, Egypt’s water availability is reasonably feared.

Expanding the GERD fitting cycle to more than 12 years will contribute to Ethiopia’s substantial financial damage. The intangible value of GERD for international economic and trade growth should be taken up by Egypt and Ethiopia. Ethiopia has little oil or natural reserves but has a considerable power generation capability of nearly 45,000 GW. The above enables it to distribute energy to regions linked to the energy pool in Eastern Africa.


The battle for worldwide for communication satellite network internet is on

The globe’s largest technological giant company is putting lots of millions of dollars into advancing the most exceptional satellite-incorporated communication network.

People using computers and other electronic devices send over 50,000 gigabytes of data to one another, and roughly three-quarters of the whole population throughout the globe are connected with the internet. Places such as North America and Europe have dispersions of 90% and 80%, respectively. But continents such as Africa and Asia both joined to get to go past 50% because on those continents, and there are many far-off regions where there is no internet connection or at least no internet that is inexpensive just to give it the benefit of the doubt.  

Lack of fiber optic cables or just the connection through radio brings the other choice of moderately costly substitute of satellite communication, and they are called the geostationary satellites. They are situated above the equator at an altitude of over 30,000km and rotate at speed, similar to the rotation of the earth. The footmark of such a satellite-only shields parts of surfaces belonging to the planet, and a computer bit consumes a lot of time to go up and down even though it travels through the vacuum of space at the intensity of light.

The solution is to come up with a worldwide network of internet service that is broadband-based, but without delay, the answer is to utilize telecommunication satellites that are orbiting near the earth; with this, the computers behave well by going up and down rapidly hence having less time in delay.

The concept of coming up with such a satellite network came through years back, and the iridium consortium made the first endeavor. Around the late ’90s, the first telecommunication was born, and its main objective was to construct a network of satellites, but on the verge of that, the company went broke billions of dollars were lost.

This led to the collapse of the company because of financial reasons, but again that was not the only problem; other problems included low quality of indoor reception, usage of bulky devices, and the general maladministration of the project. It started again, and it released sixty-six satellites; hence the reviewed satellite network gives out telecommunication services in far-off areas.

Another company that endeavored to construct a worldwide satellite network to offer communication network internet service is OneWeb, and it went broke because of the Japanese Softbank which pulled their investment out which was over a billion-dollar 

If we look at all the advancement around the global network that has no delay and provides affordable and accessible internet access, there are lots of tasks to be carried out.


NASA’s Webb Telescope to help in Further studies of the Solar System

Asteroids and Trojans are spread from Mars onwards. They appear as race cars in the formation of the solar system. NASA’s James Webb Space Telescope is helping Andrew Rivkin of Johns Hopkins University Applied Physics Laboratory team in their research about these chunks of rocks. The team hopes to collect new data to shed more light on such astronomical mysteries.

Rivkin says that vital information about asteroids is their infinite number, which means they will always observe something with the Webb.

Rivkin is partnering with other aerospace experts to perceive the asteroids in near- and mid-infrared light. Their research aims to add new findings of asteroids, their composition, and hints of the history of how planets used to orbit the sun. Over the years, technical data spells that the sun was a small mass of dust and gas. The theory then speculates that the scattered gases and dust around the sun started condensing, and with gravitational influence, planets began forming.

The theory suggests that Jupiter, Neptune, Saturn, and Uranus keep moving away from their initial position. It records that Jupiter’s movement stirs up these asteroids making them never merge. Scientists have come to realize that asteroids are rocky leftovers of rocky planets and moved from their previous location.

The Rivkin-led research team is planning to explore three asteroids and two Trojans to gather more information about them as they test new techniques with Webb Telescope. They are going to study the asteroids with NIRSpec, Near-Infrared Spectrograph. This instrument decomposes light into a spectrum that scientists can use to understand the components of the asteroids.

The scientists are targeting Ceres, which has ammonia on its surface. This information is the findings of NASA’s Dawn spaceship. The scientists are going to understand if this dwarf planet collected material from the space field. The team plans to obtain additional data to verify if the surface composition of Ceres is truly ammonia. The findings are also going to help analyze if the Webb is capable of observing brighter space material. Milam says this is going to pave the way for other scientists to do research.

Another critical target asteroid is Pallas. Docking at this asteroid is hard because of its orbit. Webb comes in handy to obtain data from this asteroid. The team then will contrast Pallas with other asteroids like Hygeia and Ceres. The comparison is going to help understand the formation of the asteroids.

The Trojan targets for the team are Hektor and Patroclus. They are essential because they have moons and are closer to Jupiter. The binary Patroclus has more space to its moon while Hektor is and has its moon orbiting close to it. The team intends to study the two together with their satellites. They hope to understand why these Trojan asteroids are in their current orbits.

The team says that their targets are relevant to current and future missions. For instance, Patroclus is a target for the next Lucy mission. Thomas, one of the researchers, adds that the data to be gathered through Webb is essential for comparison with earth-based observatories.

By understanding the mysteries of these asteroids, the team can reasonably speculate the solar system’s appearance in the past. The team reiterates that Webb is a crucial instrument because it uses its infrared light in observing targets that other facilities are unable to find. Rivkin adds that Webb gathers more data compared to ground-based telescopes.

Milam says that the findings of Webb are going to spark questions about the solar system. In this way, scientists can develop ideas to develop Webb and continue the solar system exploration. This research forms the GTO program. GTO provides opportunities for scientists to evaluate the reliability of Webb in its development. Hammel, one of GTO program scientists, says that this research aims at paving the way for future research with Webb.

Finally, the Webb Telescope is going to gather data about unanswered questions of the solar system. Webb’s launch in 2021 is going to spark the urge of scientists to explore the solar system.
