BERLIN : Electric robots are mapping the seafloor, Earth’s last frontier

Published

BERLIN : For centuries, humans have explored the Earth’s mountains, jungles and deserts. But despite covering more than 70% of the Earth’s surface, the ocean is still a relative mystery. In fact, we know more about the surface of Mars than we do about the sea floor; just over 20% of the ocean bed has been mapped.
Getting a fuller picture would enable us to navigate ships more safely, create more accurate climate models, lay down telecommunication cables, build offshore windfarms and protect marine species — all part of what’s known as the “blue economy,” projected to be worth $3 trillion by 2030.
Underwater robotic vehicles equipped with sensors are helping gather that data quicker and more cheaply than ever before. But many of these vehicles rely on batteries with a limited lifespan, and need to return to a boat or the shore to recharge, making it difficult for them to map more remote parts of the sea.
A five-year-old startup called Seatrec is rising to the challenge, founded by oceanographer Yi Chao. While working at NASA, he developed technology to power ocean robots by harnessing “the naturally occurring temperature difference” of the sea, Chao told CNN Business.

Greener and cheaper
The power module can be installed on existing data-gathering robots or Seatrec’s own floating device. This dives a kilometer down to examine the chemistry and shape of the seabed, using sonar to create a map of the surrounding area. The robot returns to the surface to send back its findings via satellite.

Seatrec’s float uses differences in ocean temperature to power itself.
As the float moves between colder and warmer parts of the ocean, material inside the module either melts or solidifies, causing pressure that in turn creates thermal energy and powers the robot’s generator.
“They get charged by the sea, so they can extend their lifetime almost indefinitely,” Chao said.

A basic float model typically costs around $20,000. Attaching Seatrec’s energy system adds another $25,000, Chao said.
But the access to free, renewable energy and the ability to stay in the water longer makes data gathering up to five times cheaper in the long run, according to Chao. He said the startup is making fewer than 100 devices per year, primarily for marine researchers, but the technology is easily scalable — Seatrec’s energy module can also be can be retrofitted onto existing mapping devices to extend their range.
Picking up the pace
New technologies that can extend the reach of data-gathering devices are crucial for mapping more remote parts of the deep sea, according Jamie McMichael-Phillips, director of the Nippon Foundation-GEBCO Seabed 2030 Project.
“One of the huge challenges we have is quite simply physics,” said McMichael-Phillips. “Unlike mapping the Earth’s surface where we can use a camera [or] satellites, at sea, light does not penetrate through the water column. So we’re pretty much limited to using sonar systems.”

Launched in 2017, the Seabed 2030 Project has increased awareness about the importance of the ocean floor, and given researchers and companies a clear goal to work towards: map the entire seafloor by the end of this decade.
Some companies, such as XOCEAN, are surveying the ocean from the surface. Another startup, Bedrock Ocean Exploration, says it can provide surveys of seabed areas up to 10 times faster than traditional methods by using an autonomous electric submarine fitted with sonars, cameras and lasers; the data is then analyzed on Bedrock’s own cloud platform.

The challenge ahead
Even with the growing number of technologies accelerating seabed exploration, completing the map is still a logistical and financial challenge.

Chao estimates that it would take 3,000 of Seatrec’s floats operating over the next 10 years to fully survey the ocean. The company has raised $2 million in seed funding to scale up production of its energy harvesting system.
But this is a drop in the ocean of the capital needed to fully survey the ocean, which is estimated to be “somewhere between $3 to $5 billion,” according to McMichael-Phillips — “pretty much the same order of magnitude as the cost of sending a mission to Mars.”
Bedrock’s DiMare believes it’s time we start investing in our own planet.
“If we want to keep Earth as a place that humans can live,” he said, “we have got to get a lot smarter about what’s going on in the ocean.”

SAN FRANCISCO: Indian-Origin Founder Unveils Wearable Device That Records Every Moment Of Your Life

Published

on

SAN FRANCISCO: Advait Paliwal, an Indian-origin entrepreneur, has recently introduced a wearable AI device called Iris, designed to provide users with “infinite memory.” According to Paliwal, the device captures “pictures every minute,” which are stored either on the device or in the cloud, allowing users to preserve life’s small moments and recognize patterns often overlooked.

In a series of tweets, Mr Paliwal, who is based in San Francisco, explained that Iris not only organises the photos into a timeline but also uses AI to generate captions and help users recall forgotten details. Additionally, the device features a “focus mode,” which detects when the wearer is distracted and offers reminders to refocus.

Mr. Paliwal shared that the design of Iris is inspired by the evil eye symbol. He developed the device over the summer at the Augmentation Lab in Cambridge, part of a two-month AI and hardware talent accelerator program. After the program, Mr Paliwal presented Iris to over 250 attendees at the MIT Media Lab, where he received positive feedback, with many expressing interest in owning the device.

Highlighting its potential, Mr Paliwal suggested that Iris could offer safety and health benefits, such as aiding doctors in understanding patients’ daily habits or ensuring workplace safety compliance. In elderly care, the device could help caregivers monitor patients without being intrusive.

However, after Mr Paliwal shared his post on X (formerly Twitter), reactions were mixed. While some users expressed excitement, others raised privacy concerns. One person commented, “It’s an interesting concept, but I wouldn’t want to interact with someone wearing this, taking a photo every minute.” Paliwal responded by pointing out that people are already “constantly taking mental photos.”

 Others were more enthusiastic, with one user noting, “I’ve been searching for a device like this for years! A picture every minute should be enough if it archives, organizes, labels, and retrieves them.” Another user praised the concept, saying, “Love the idea. The design and name are perfect. Great work!”

TEXAS: Meet Gopi Thotakura, Indian Who Will Soon Go To The Edge Of Outer Space

Published

TEXAS: In an unprecedented leap towards the stars, pilot Gopichand Thotakura is set to become the first Indian to venture into space as a tourist. Selected as part of the elite crew for Blue Origin’s New Shephard-25 (NS-25) mission, Mr Thotakura will make a journey beyond the Earth’s atmosphere along with five other candidates.

Gopichand Thotakura, an entrepreneur and pilot, joins a distinguished lineup of 31 candidates who have flown beyond the Karman line, the boundary between Earth’s atmosphere and outer space.

A connoisseur of the skies since his youth, Mr Thotakura’s passion for flight saw him defy conventional norms, learning to pilot aircraft before mastering the art of driving. To further his passion, he graduated from Embry-Riddle Aeronautical University with a Bachelor of Science in Aeronautical Science.

Describing him, Blue Origins wrote, “Gopi is a pilot and aviator who learned how to fly before he could drive. Gopi pilots bush, aerobatic, and seaplanes, as well as gliders and hot air balloons, and has served as an international medical jet pilot. A lifelong traveler, his most recent adventure took him to the summit of Mt. Kilimanjaro.”

Born in Vijayawada, the 30-year-old currently runs Preserve Life Corp, a global center for holistic wellness and applied health located near Hartsfield-Jackson Atlanta International Airport

Each member of the NS-25 mission will carry a postcard on behalf of Blue Origin’s foundation, Club for the Future, symbolizing the collective dreams and aspirations of young minds worldwide.

From an environmental standpoint, the NS-25 mission heralds a new era of sustainability in space exploration.

“Nearly 99% of New Shepard’s dry mass is reused, including the booster, capsule, engine, landing gear, and parachutes. New Shepard’s engine is fueled by highly efficient liquid oxygen and hydrogen. During flight, the only byproduct is water vapor with no carbon emissions,” Blue Origins said in their statement.

The launch date for the mission is yet to be announced.

The mission also includes former Air Force Captain Ed Dwight, who was selected by US President John F Kennedy in 1961 as the country’s first Black astronaut candidate but was never granted the opportunity to fly to space.

Blue Origin has carried out six crewed flights — some passengers were paying customers and others were guests — since July 2021, when CEO Jeff Bezos himself took part in the first.

The company is also developing a heavy rocket for commercial purposes called New Glenn, with the maiden flight planned for next year.

 This rocket, which measures 98 meters (320 feet) high, is designed to carry payloads of as much as 45 metric tons into low Earth orbit.
