Homes Could Use the Ocean’s Energy to Power Their Homes

Different Kinds of Energy

Who doesn’t want clean energy at a great price? Natural gas is expensive and comes at a high environmental price. Solar energy is a great clean source but is rare in most places because of a lack of infrastructure. People find nuclear energy frightening because of past accidents. So it is great news that it may be possible to use the energy from the ocean to power homes.

Why Do Homes Need So Much Energy?

Most of the energy homes use is necessary to make them comfortable. About half of all energy goes to heating and cooling, although obviously, some places have either more or less of a need than others based on geographic location and/or other home features, such as insulation. About a quarter of the home’s energy goes to heating water, such as for showers and cleaning, and for the home’s washer and dryer.

Ocean Power

Strong ocean tides carry with them an enormous amount of energy. Unlike many other kinds of energy, there is no limit to the energy found in the seas. Unlike other natural resources, ocean power will theoretically never run out. The question is whether that energy can be harnessed for use on land.

Wavespring

New ocean wave technology shows promise as a possible source of reliable and affordable power.Archimedes Wavespring is a unique new system that operates by use of a wave power buoy that is positioned under the waves. Because of its position below the surface, Wavespring avoids dangerous conditions such as storms and wind forces.

The buoy reacts to changes in passing waves, converting the motion of the ocean to electricity by way of a direct-drive generator. Single buoys may be at least 25 meters deep with ratings between 15kW and 500kW, and there are also potential configurations with multiple absorbers that may have up to 10MW.

Simple and Affordable

Because of the simple concept and set-up, costs are kept to a minimum for both installation and use. Affordability may help make the technology more likely to be adapted, as one of the biggest reasons people reject change is because people are worried that they will not be able to afford it. In fact, this system is so affordable that many companies may realize that it is more affordable than the power system already in place.

So far, data show encouraging results. Trials at the European Marine Energy Centre in Orkney exceeded the developer’s expectations by 20%. The trials also showed how durable the equipment was, as it remained operational even after undergoing rough weather conditions. Hopefully, the world can start reaping the benefits of this new technology soon.

Southern California Business Developed A Genius Way To Reuse Water

For many years, California has been suffering from severe drought, with water shortages becoming a common issue for residents and businesses alike. To combat the drought, one Southern California company has developed a revolutionary system for reusing water.


The Water Recycling System (WRS) captures and purifies greywater from sources such as sinks, showers, and laundry machines. This treated water is then stored in tanks before being reused for irrigation, toilet flushing, and other non-potable purposes.


According to the company, their system can save up to 50% of a building’s total water usage, which is significant given that the average American household uses about 300 gallons of water per day. The system is versatile in that it can be installed in both residential and commercial buildings, making it a viable option for both homeowners and business owners.


According to the company’s owner, the system is simple to install and maintain, and it can pay for itself in a matter of years through water savings. The system costs $5,000 to $20,000 to install, depending on the size of the building, and the company offers financing options for those who cannot afford the upfront cost.


The system not only helps to conserve water, but it also helps to reduce the carbon footprint of a building by reducing the amount of water that must be pumped from treatment plants and delivered to the building. The system can also help to alleviate the strain on sewer and septic systems, which can become overburdened during times of drought.

New Whales for the New Year

Seeing young whales being born and thriving is a dream for many biologists and conservationists. And 2023 is turning out already to be a year that many of the endangered whale types may see a positive boost from. So far, just at the turn of 2023, three new baby whales have been born, and together to boot. The news was announced from the New England Aquarium, right on New Year’s Eve as the new year was rung in.

The particular species that now enjoys three new additions is the North Atlantic Right Whales. The particular pod was spotted by the Clearwater Aquarium’s staff off the coast of Florida. The news was spread among the whale community quickly, especially given the fact that the given species only has 340 known animals alive now.

The winter season has always been tracked as a calving season in whale studies. Many of the pregnant whales showcase their new young off the Southeastern shore of the U.S. once born, and this holiday season was no exception. For the North Atlantic Right Whales, any growth in their numbers is good news. The species was hunted for years, being viable as a commercial ocean harvesting target, and then additional casualties were lost due to collisions with ships as well as being unintended victims in fishing nets.

As it turns out, the current season has been particularly strong in terms of new calves. A total of eight new whales have been spotted in the last few weeks. Each whale is identified as an individual based on the callosities or scars on the heads of the Right Whales. Some have been around for many years, giving birth to new calves year after year. One particular whale, an older one aging at least 33 years so far, is known for sure to have birthed four calves and lost a fifth in 2019.

Unfortunately, calf mortality is high among whales for a variety of reasons, and humans don’t help for the most part. Worse, the adult whales are calving less and less frequently, now longer than the 3 to 4 year average.

One of the mothers of the recent calves is well known; Aphrodite has been around at least 36 years and has had scarring or violent interactions recorded with human boats at least 28 times in that lifespan. However, she has managed to birth yet another new whale this year. As a result, hopes are high that her new young will make it to adulthood if it has its mother’s tenacity.

Corals Being 3-D Printed Tiles Used for Coral Restoration Thanks to Hong Kong Startup

Published

on

At least one entity is using creative measures as a means to help save the planet, more specifically, coral reefs. It has long been known that corals across the globe have been deteriorating rapidly due to natural and manmade causes.

With its creative utilization of 3D printing and terracotta, a Hong Kong business is attempting to aid coral in adapting to the issues brought by people.

Hong Kong’s subtropical waters support more coral species than the Caribbean, although the South China Sea region once had even more breathtaking scenery.

According to the University of Hong Kong’s coral ecologist David Baker, “We think that this location was a coral heaven.” The World War II era members who are still living will tell you that the coral was abundant and the water was clear.

However, drainage and pollution seeped into the seas as Hong Kong industrialized.

To restore the “paradise lost,” Baker co-founded the eco-engineering business Archireef.

In a first for the world, his team 3D printed terracotta tiles that resemble artificial reefs. They are biodegradable as well as non-toxic. The tiles were planted with living coral by the team on the sand bottom of a sheltered harbor, and 95% of them have survived for the past couple of years.

Baker responded, “I just considered to myself one night, why not tile the ocean bottom like we’d tile a bathroom or kitchen floor,” when asked how the idea came to him.

The tiles may be used all over the world to help corals adapt, which would be advantageous for both people and marine life. Reefs deflect storm-generated waves away from buildings to safeguard them. Coral supports more than a billion people and is crucial to aquaculture, tourism, and now even healthcare.

In the next two decades, 70 percent to 90 percent of coral worldwide is expected to perish, according to scientists.

In Abu Dhabi, where it also has a modern manufacturing 3D printer, Archireef has expanded.

Vriko Yu, the other co-founder of Archireef, stated, “We utilize our eco-engineering center.”

Yu recently relocated from Hong Kong and wants to aid coral with their relocation. The water temperature in the Persian Gulf can reach 118 degrees; higher temperatures are lethal.

We can enable corals to migrate so they can relocate to deeper waters, Yu added.

Reef tiles could also aid in reunifying isolated coral ecosystems that have been split apart by the massive die-offs brought on by climate change.

50 Years Later – A Vietnam War Surgeon Meets A Previous Patient

Mayer Katz has seen a lot in the world, and the Vietnam War was no exception. Like many in his time, he found his medical training critical for not just healing wounds, Katz was also essential at saving lives as well. That initial service was captured in more than just actions, however. As it turned out, Katz’s work was also captured in photography.

The place was a city named Hue and the year was 1968. The location was a battlefield as U.S. marines were fighting a bloody battle to reverse the Tet Offensive and take back the city from the Viet Cong who had snuck in en masse the night before. It was ugly, house-to-house, close quarter fighting costing thousands of lives for every inch. Along with the soldiers, journalist photographers were risking their own lives capturing images. One of them turned out to be a wounded marine being given first aid on top of a tank, and the photograph was captioned as well, identifying the hurt soldier. As it turned out, however, Katz had worked on that particular marine.

Katz didn’t know it right away. In fact, it took 50 years later for Katz to realize the connection while going through a vivid history book with the same photographs taken back in Hue. And, on the bottom of the particular one with the wounded marine on the tank, Katz saw the name in the caption: A.B. Grantham. That name rang a bell, and Katz went back to his medical records, meticulously kept for every surgery he worked on. And there it was, A.B. Grantham’s surgery in the 22nd Surgical Hospital, at the Hue airbase on February 17 of the same year, 1968. Katz’s records also had all of the medical details, functioning as a logbook of the surgery, just like he did for every other one performed before and after.

Grantham remembered the wound he got in Hue. In his own words, the bullet went in him with the same sensation as a red-hot poker being stabbed in his chest. Grantham’s fortune was crafted by the fact that he had fellow marines right next to him that could drag Grantham to safety and first aid. Using whatever was available, cigarette wrappers, napkins and leftover bandages, they plugged the wound and kept Grantham’s critical blood flow in his body more than was leaking from the wound. That initial work kept Grantham alive long enough to get to the Hospital, and that’s where Katz did his magic. A captain at the time, Katz didn’t always save every soldier that came his way, but Grantham was going to be a point on the right side of the picture.

Katz also had the benefit that his patient was in top form and health too. That typically makes a difference in trauma recovery as well. It took hours, 10 blood units, and part of a lung, but Katz was able to save Grantham. The marine went on to live, get married, have kids, get divorced, get married again and start a business. And he survived PTSD as well from the war. Katz gave Grantham that chance to keep going.

Long story short, the photograph from 50 plus years earlier ended up connecting them again. Katz’s daughter reached out the photographer, who then connected Katz and Grantham. As the marine put it, Katz was finishing a surgery followup, just a few decades later. Today they give each other garbage about their favorite football teams, which is probably a lot better than trading bullets and bandages.
