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.

Cybersecurity firm reports exposure of sensitive DeepSeek data on the internet.

The New York-based cybersecurity firm Wiz has discovered a cache of sensitive data from the Chinese artificial intelligence business DeepSeek that was mistakenly exposed to the public internet.

In a blog post released on Wednesday, Wiz reported that examinations of DeepSeek’s infrastructure revealed that the company had inadvertently exposed over a million lines of unencrypted data. The materials were digital software keys and chat logs that seemingly documented prompts transmitted from consumers to the company’s complimentary AI assistant.

The chief technical officer of Wiz stated that DeepSeek promptly safeguarded the data following the notice from his organisation.

“It was removed in under an hour,” stated Ami Luttwak. “However, this was exceedingly easy to locate, leading us to believe we are not the sole discoverers.”

DeepSeek did not promptly respond to a request for comment.

DeepSeek’s rapid success after the introduction of its AI helper has exhilarated China and incited concern in America. The Chinese company’s evident capacity to rival OpenAI’s skills at a significantly reduced cost has raised concerns regarding the viability of the business models and profit margins of U.S. AI behemoths like Nvidia and Microsoft.

By Monday, it surpassed the U.S. competitor ChatGPT in downloads from Apple’s App Store, prompting a worldwide decline in technology stocks.

WhatsApp launches bulk channel management functionality

Published

By

WhatsApp has initiated testing of a bulk channel administration feature on iOS for select beta users, enabling the simultaneous selection of many channels, hence enhancing the efficiency of managing following channels.

This essential update enables users to perform bulk activities, including muting many channels simultaneously, designating them as read, and altering notifications. If the chosen channels are muted, users will now have the option to activate notifications. Users can swiftly silence unmuted channels in one action.

Additionally, this feature enables users to unfollow many channels simultaneously, thereby optimizing the process of decluttering their channel list. This change is particularly beneficial for users that oversee numerous subscriptions, as reported by WABetaInfo.

Previously, users were required to manage each channel individually, rendering tasks such as muting or designating channels as read laborious and time-consuming.

The functionality provides enhanced flexibility and control over channel subscriptions, enabling users to efficiently manage notifications. The solution streamlines laborious operations for consumers who subscribe to numerous channels, hence enhancing their entire experience.

Accessibility
The bulk management feature is presently accessible exclusively to a limited number of beta testers who installed the latest WhatsApp beta for iOS using the TestFlight application. WhatsApp, owned by Meta, plans to expand the feature’s availability to a larger user base in the next weeks.

This update demonstrates WhatsApp’s dedication to enhancing user experience by offering a clear and efficient method for managing channels and notifications.
