Scientists ‘planning to grow food’ on moon

Published

After successfully managing to grow beans — the main source of nutrients for humans — with the help of lunar soil, astronomers and scientists from Europe have formulated a remarkable plan to grow crops and attempt to grow Agricultural products and crops on the moon.

After analysing the data about the soil of the moon, it has revealed that its soil, which is known as regolith has crucial minerals for the growth of plants, however, it has also shown that nitrogen is not available in it.

The soil of the moon also becomes thick as water is poured on it which is feasible to prevent air penetration and allows roots to grow.

In the case of nitrogen’s absence, the scientists from the European Space Agency (ESA) have found another way to fulfil their objective of the lunar plantation. It is hydroponic farming in which plants grow inside of nutrient-rich water, making soil redundant.

The experts at Norway’s geotechnical Institute are on board with the ESA scientists to achieve the aim of lunar agriculture growth — fulfilling the commitment to actually leave the planet.

With the help of mechanical characterisation, the team has finalised a plan to carry out all the necessary action needed in hydroponic farming that includes extracting all the minerals and nutrition from regolith and injecting them into the garden’s water.

According to ESA materials and processes engineer, Malgorzata Holynska, this work lays the foundation for future space exploration.

Holynska opined that attaining a sustainable presence outside earth will involve using space’s resources and gaining access to nutrients present on the moon’s surface that can help plantations.

The current study reinforces evidence of using regolith minerals to grow plants — and further allowing the scientists and experts to carry out future research on the subject, Holynska added.

According to a report by the U.S.-based think tank Global Energy Monitor (GEM), China is constructing 339 gigawatts (GW) of utility-scale wind and solar energy, which accounts for 64% of the total global capacity. The project pipeline of the first-place country is more than eight times that of the second-place U.S., which has 40 GW.

The authors of the paper stated that China’s rapid progress makes it highly achievable to treble renewable capacity by the end of 2030, even without more hydropower. They urge China to increase its climate ambitions in its upcoming promises to the United Nations next year.

Last week, the Sydney-based think tank Climate Energy Finance said that Beijing is on course to achieve its own target of installing 1,200 GW of wind and solar power by this month, which is six years ahead of schedule.

According to GEM research analyst Aiqun Yu, China’s coal-centric power grid is facing difficulties in accommodating the rapid growth of renewable energy sources. To address this issue, there is a need for the accelerated expansion of transmission lines.
However, a different analysis published by Carbon Brief on Thursday revealed that the recent increase in capacity has resulted in renewable generation reaching unprecedented levels.

According to the analysis conducted by Lauri Myllyvirta, senior fellow at Asia Society Policy Institute, China’s electricity generation from coal reached a record low of 53% in May. At the same time, a record high of 44% of electricity came from non-fossil fuel sources. This suggests that China’s carbon emissions may have reached their highest point last year, assuming this trend continues.

The percentage of coal decreased from 60% in May 2023.

In May, solar power generation increased to 12% and wind power generation reached 11%, primarily due to China’s significant addition of new capacity. The remaining non-fossil fuel electricity was comprised of hydropower at 15%, nuclear power at 5%, and biomass at 2%.

In May, the power industry in China experienced a 3.6% decrease in carbon dioxide emissions, which account for almost 40% of the country’s total emissions, due to the increased generation of renewable energy.

“According to Myllyvirta, if China continues to rapidly deploy wind and solar energy, it is expected that the country’s CO2 emissions will continue to decrease, with 2023 being the year when emissions reach their highest point and start to decline.”
In May, solar power generation had an unprecedented increase of 78% compared to the previous year, reaching a total of 94 terrawatt hours (TWh).

According to China’s National Bureau of Statistics, there was a 29% rise in electricity generation from solar power. However, this figure does not account for the electricity generated by rooftop solar panels, which represents approximately half of the total solar electricity produced.

The new analysis computed the wind and solar power production by utilizing data on the capacity of power generation and the utilization figures provided by the China Electricity Council, an industry body.

Wind power generation increased by 5% compared to the previous year, reaching a total of 83 TWh. This growth was primarily driven by a 21% increase in capacity. However, the overall utilization of wind power was lower due to fluctuations in wind conditions. Hydropower production experienced a significant increase of 39% compared to the previous year, during which it was adversely affected by a drought.

Gas-fired output experienced a decline of 16%, while power generation from coal decreased by 3.7%, despite a 7.2% growth in overall energy consumption compared to the previous year.

The instant messaging service WhatsApp, which is owned by Meta, has introduced a new function to improve group chat security.

Referred to as “context cards,” this feature aims to address the common problem of online group fraud by preventing members from being added to groups by strangers.

According to a press statement from WhatsApp, the global deployment of context cards has already started and is anticipated to be accessible to all users in the upcoming weeks.

When users receive group invites from contacts who are not saved on their phone, the context card function offers more details. The card has information about the group’s originator as well as specifics like the group’s founding date and a succinct statement of its goals. Users are able to join new groups with greater knowledge thanks to this additional background.

Context cards seem to offer very little information, but their purpose is to give consumers enough information to make an informed decision about whether or not to accept a group invitation. In addition, people who have doubts about the authenticity of the invitation have the option to report, block, or unsubscribe from groups.

The new feature was unveiled by WhatsApp CEO Cathcart on his channel within the app, with a focus on how it could shield users from common online group scams.

Beta testers who update their WhatsApp beta for Android will have access to this new functionality. It will be made available to the general public in the next few days.

WABetaInfo’s research reveals that WhatsApp is currently working on a feature that allows channel owners to forward and exchange messages and media on their channels. This functionality enables users to effortlessly distribute messages, photographs, videos, and GIFs from their individual conversations directly to their channels.

Currently, it seems that the instant messaging software is conducting a trial of this modification with the general public, as certain users in the beta program now have the opportunity to try out the new channel forwarding option.
The report’s screenshot disclosed that certain beta testers now have the ability to test a feature that allows them to forward messages, photographs, videos, and GIFs to their channels.

In addition, channel owners have the capability to directly distribute their media from other applications, such as the file explorer, to their channels without any intermediate processes.

This facilitates the rapid sharing of content, ensuring that channels remain current and enhancing interaction. The addition of the new functionality that enables channel owners to promptly distribute messages, photographs, videos, and GIFs straight to channels represents a significant advancement. By eliminating needless procedures, it greatly simplifies the management of channels.

Users are no longer need to store media on their devices and manually submit it to the channel. Alternatively, users have the option to immediately transmit content from their own conversations or distribute media from other applications such as file explorers or the photo library directly to their channels.

According to WABetaInfo, they feel that it decreases the amount of time and energy that channel owners typically dedicate to producing and uploading material, resulting in a more instant connection with channels.
