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

Published

on

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.

Google abandons its plans to do rid of cookies in Chrome

The significant change in course comes as a result of worries expressed by advertisers, who provide the majority of the company’s revenue, that their capacity to gather data for customised advertisements will be restricted due to the removal of cookies from the most widely used browser in the world, leaving them reliant on Google’s user databases.

Due to worries that Google’s proposal would stifle competition in the digital advertising market, the UK’s Competition and Markets Authority has also carefully examined the proposal.

“Rather than discontinuing third-party cookies, we would launch a fresh experience in Chrome that empowers individuals to make a knowledgeable decision that is applicable to all of their online browsing, and they could modify that decision whenever they choose,” stated Anthony Chavez, vice president of the Privacy Sandbox project, which is supported by Google, in a blog post.

A major objective of the Privacy Sandbox project, which was started in 2019 by Alphabet (GOOGL.O), opens new tab unit, is to phase out third-party cookies while simultaneously improving online privacy and boosting digital enterprises.

Though they can potentially be used for unauthorised monitoring, cookies are information packets that websites and advertisers use to identify specific online users and follow their browsing patterns.

Within the European Union, publishers are required to obtain explicit agreement from users before storing cookies, as per the General Data Protection Regulation (GDPR). Cookie deletion is another feature that most popular browsers offer.

While continuing to fund the Privacy Sandbox programme, Chavez stated that Google was collaborating on the new strategy with publishers, privacy organisations, and regulators like the UK’s Information Commissioner’s Office and CMA.

Many responded differently to the announcement.

Analyst Evelyn Mitchell-Wolf of eMarketer stated in a statement, “Advertising stakeholders won’t have to prepare to quit third-party cookies cold turkey.”

One example of how cookies can hurt consumers is when they display predatory advertisements that target specific demographics, according to Lena Cohen, a staff technologist at the Electronic Frontier Foundation. According to Cohen, Google’s choice to keep accepting third-party cookies is a direct result of their advertising-driven business model, even though other major browsers have been banning them for years.

On social media, a number of users have reported that although media files like movies and photographs are not loading or processing regularly, WhatsApp calls and text messages are working as usual. By comparison, WiFi users can seamlessly utilize WhatsApp.

WhatsApp is down.During peak hours after Youm-e-Ashur, the issue with media loading was at its worst. No explanation for the ongoing problem has been provided by the Pakistan Telecommunication Authority (PTA). The topic is presently being looked at by major cellphone operators.

Many users had reported frequent breakdowns on X and LinkedIn, and the bug has previously also affected other Meta apps, such as Facebook and Instagram. That disruption, meanwhile, is currently mainly confined to mobile network users’ access to WhatsApp services.

Facebook users had issues across multiple internet service providers (ISPs) after local authorities limited access to the social media platform earlier this week without any formal announcement. WhatsApp and Instagram were also affected by this restriction at the time, according to Downdetector.

Although the administration was meant to know how or if to eliminate the limitation by July 17, it doesn’t seem like they have made up their minds.

Due to major technical issues that Pakistani users have been having since Muharram 9th, Facebook users on July 17 witnessed widespread irritation and conjecture on the social media platform.

People in Pakistan have moved to alternative social media platforms, such as X (previously known as Twitter), to express their worries after reports surfaced that several ISPs have been unable to access Facebook and Instagram since Tuesday.

With the assistance of the Special Investment Facilitation Council (SIFC), the information technology industry is expanding significantly.

This year, the government has set aside seventy-nine billion rupees for the information technology sector, taking into account its extensive potential.

Amounts of 19 billion and 22 billion rupees, respectively, have been set aside for the Pakistan Software Export Board and the development of IT parks in Islamabad and Karachi.

With SIFC’s assistance, the IT industry is expanding quickly, and a large number of start-ups are making their global debuts.

The nation’s IT exports will increase, as Prime Minister (PM) Shehbaz Sharif had already promised.

A complete package for the IT industry needs to be prepared, the prime minister stressed while chairing a high-level meeting on the industry’s promotion.

Along with forming a committee to study the issue and instructing it to give recommendations as soon as possible, PM Shehbaz opted to include a fixed tax regime for the IT sector in the budget.

The government would invest a significant sum of money in training young people for careers in the IT industry, according to PM Shehbaz. As of right now, he continued, 45,000 youth nationwide are receiving IT-related training.
