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.

As news broke that Donald Trump’s social media company was in negotiations to acquire cryptocurrency trading platform Bakkt (BKKT.N), Bitcoin surged to a record high above $94,000, adding to optimism that the next Trump administration would be cryptocurrency-friendly.

This year, Bitcoin, the largest and most well-known cryptocurrency in the world, has more than doubled in value. Just before the close of the previous session, it reached a record high of $94,078 before closing at $92,104 in Asian hours on Wednesday.

According to the Financial Times, which cited two persons with knowledge, NYSE-owner Intercontinental Exchange (ICE.N) is supporting Trump Media and Technology Group (DJT.O), opens new tab, which runs Truth Social, in its pursuit of an all-stock purchase of Bakkt.

In addition to traders taking advantage of the first day of options trading on the Nasdaq over BlackRock’s Bitcoin ETF (IBIT.O), Tony Sycamore, market analyst at IG, stated that the Trump deal chatter had helped push bitcoin to a record high.

As traders hoped that President-elect Trump’s pledged support for digital assets would result in a less stringent regulatory framework and give bitcoin a boost after a sluggish few months, cryptocurrencies have surged since the U.S. election on November 5.

According to data and analytics aggregator CoinGecko, the global cryptocurrency market is now worth over $3 trillion, a new high, due to the growing excitement.

Australian online broker Pepperstone’s head of research, Chris Weston, stated that there is genuine underlying purchasing pressure on bitcoin and that “another kick higher should bring in a fresh chase from those who like to buy what’s strong.”

The PTA discloses how many VPNs are registered in Pakistan.

Speaking at the Senate Standing Committee on IT meeting in Islamabad, which was presided over by Palwasha Khan, was the PTA chief.

The continuous regulation of Virtual Private Networks (VPNs) in Pakistan was the main topic of discussion. The committee called for the next meeting and voiced concerns about the Minister of State for IT’s absence for the third consecutive session.

“We have spent the last two years developing VPN legislation. Uninterrupted internet connection is guaranteed by registered VPNs without sacrificing privacy, according to the PTA chairman.

During the session, Senator Muhammad Humayun criticized the measures, saying, “Shutting down platforms like X (formerly Twitter) is jeopardizing the entire IT industry and impacting the livelihoods of over 2.5 million individuals in Pakistan.”

He opposed laws that would hurt independent contractors and small companies.

Although the PTA promised that registered VPNs would not experience internet outages, committee members wanted to know the exact legal foundation for these regulations. Senator Kamran Murtaza asked for documents that detailed the requirements for registration.

“If VPN services are abruptly halted, there will be a major backlash,” Senator Afnan Ullah said. While pointing out that Pakistan’s IT exports had increased by 20% in the previous year, he emphasised that the sector was still lagging behind India.

Concerns over the viability of the existing VPN whitelist method were voiced by the committee. While IT officials admitted that more than 1 million freelancers in Pakistan rely significantly on VPNs for their business, Senator Humayun pointed out that the laws should be more beneficial than harmful.

The National Computer Emergency Response Team (CERT) has released a security advisory concerning the increasing utilization of artificial intelligence (AI) chatbots, emphasizing potential hazards related to the exposing of private data.

The recommendation recognizes that AI chatbots, like ChatGPT, have gained significant popularity for personal and professional duties owing to their capacity to improve productivity and engagement. Nonetheless, the CERT cautions that these AI systems frequently retain sensitive information, so posing a danger of data breaches.

Engagements with AI chatbots may encompass sensitive information, such as corporate strategy, personal dialogues, or confidential correspondence, which could be compromised if inadequately safeguarded. The warning emphasizes the necessity for a comprehensive cybersecurity framework to alleviate concerns associated with AI chatbot utilization.

Users are advised against inputting critical information into AI chatbots and are encouraged to deactivate any chat-saving functionalities to mitigate the danger of unwanted data access. The CERT additionally advises performing routine system security checks and employing monitoring tools to identify any anomalous behavior from AI chatbots.

Organizations are urged to adopt rigorous security protocols to safeguard against possible data breaches resulting from AI-driven interactions.
