Floaters that turn ocean waves into renewable energy could power our homes

Published

Blue metal floaters attached to an old World War II ammo jetty in Gibraltar’s coastline oscillate up and down, converting the moderate rise and fall of waves into renewable electricity. 

The floaters were developed by Eco Wave Power, a business that aims to turn man-made structures like breakwaters and piers into renewable energy sources.

According to the development team, each batch of these floaters is specifically created to accommodate the particular wave conditions where they are deployed. 

For instance, smaller waves require smaller floaters since they are easier to move up and down, whereas larger waves can accommodate larger floaters and hence require fewer of them.

Land-based accumulators that are built into large blue shipping containers are inflated by the movement of the floaters. 

A hydraulic motor is turned by the fluid pressure caused by the rising waves. That then starts a generator, which turns on an inverter to transfer electricity to the power grid.

The hydraulic pressure generated by the floaters is converted into electrical energy for the grid inside one of Eco Wave Power’s land-based containers.

When waves become too high during a storm, the unit automatically locks into an upright position to protect itself, and once the bad weather has gone, it descends back into the sea.

According to Eco Wave Power, its complete system — from floater to grid— is about 50% efficient, which means that roughly 50% of the wave energy that enters the system is successfully transformed into electricity. To put that number into perspective, consider that it is higher than the typical solar panel efficiency of 15% to 20%, the typical wind turbine efficiency of 20% to 40%, and the typical coal power plant efficiency of 33%, according to a CNET report.

There are now a few areas where the company consistently provides grid power, and more are on the way. The company’s first grid-connected station was inaugurated in Gibraltar in 2016 and a second one is presently being built at Jaffa Port in Tel Aviv, Israel. In early 2023, a third is anticipated to open in Los Angeles.

The quantity of energy generated by each floater depends on the local wave conditions. Each of the company’s floaters in Jaffa, according to Inna Braverman, co-founder and CEO of Eco Wave Power, may produce up to 10 kWh, or roughly enough energy for 10 households.

According to Braverman, the business has carried out numerous environmental studies, which have revealed no adverse effects on the environment. Additionally, the fluid used to generate the hydraulic pressure within the system is biodegradable.

WhatsApp is implementing a new upgrade to refine the Updates tab interface, hence boosting accessibility for status and channel updates.

WABetaInfo reports that the upgrade introduces expedited shortcuts that streamline the updating of statuses and channels. Users can now select and upload photos and videos directly from the interface, reducing the steps involved in choosing media from the gallery.

The Meta-owned messaging application has also revamped the button for generating text-based status updates and introduced a feature for recording and sharing voice status updates. This offers customers a more expedient method to disseminate text and speech updates without depending on the floating action button.

The revisions correspond with recent modifications to other tabs, ensuring a modernised interface that improves navigation and update creation. WhatsApp is modifying the floating action button to facilitate content sharing within channels.

When selecting the floating action button, users will see several options, including creating status updates, starting new channels, or sharing photos, videos, voice, and text in existing channels. This revamp integrates all content-generating options into a singular section.

The new shortcuts are anticipated to be accessible to a broader user base in the forthcoming weeks. Beta testers can currently access them in the latest WhatsApp beta for Android, version 2.24.26.13, available on the Google Play Store.

Through Chinese expertise, the arrangement, which was made possible by the Special Investment Facilitation Council (SIFC), intends to increase Pakistan’s agricultural output.

The Punjab government and China’s “AI Force Tech” company have inked a memorandum of understanding (MoU) to introduce advanced agricultural machinery during Chief Minister Maryam Nawaz’s visit to China.

Through the use of advanced robotic technology, the MoU seeks to transform Pakistan’s agricultural industry, guarantee economic growth, and boost farmers’ wealth with China’s assistance.

Through the partnership, Pakistan would also have the chance to absorb knowledge about China’s sophisticated farming methods.

In the meantime, plans have been revealed by the Federal Minister of Planning to send 1,000 agricultural experts to China to study contemporary farming methods.

A Chinese business and the Punjab government previously inked an agreement to introduce cutting-edge cancer treatment technologies to Punjab.

Maryam Nawaz signed a Memorandum of Understanding (MoU) with Hygea Medical Technologies while she was in China in order to introduce cutting-edge cancer treatment equipment and techniques to Punjab.

This equipment will make it feasible to treat cancer without the need for chemotherapy or surgery.

Following a meeting with Hygea Medical Technologies President Dr. Luo Fuliang, Maryam Nawaz said the organization has promised expert assistance for the establishment of the Nawaz Sharif Cancer Hospital.

She went on to say that the hospital will work with China to treat cancer patients utilizing the newest equipment and techniques following the agreement.

Maryam Nawaz and a high-level delegation are present. From December 8 to December 15, the chief minister will go to Beijing, Shanghai, Shenzhen, and Guangzhou.
