In just one year, Tesla and SolarCity created a solar-powered island

SolarCity and Tesla: Tau Microgrid
Island living may sound like dream, but despite those white sandy beaches, tropical weather, and seemingly endless sunshine, the dream can sometimes turn nightmarish. That was particularly true for the island of Ta’u in American Samoa, which sits over 4,000 miles away from the California coastline, and has become accustomed to power rationing, electricity outages, and similar issues.

But thanks to a new partnership between Tesla and SolarCity, Ta’u is now leveraging its sunbathed location to its advantage by way of a new “solar power and battery storage-enabled microgrid that can supply nearly 100 percent of the island’s power needs from renewable energy,” as per a SolarCity blog post.

The impressive achievement was made possible by SolarCity’s power generation and Tesla Powerpack-based storage, and has since given residents of the island a cost-efficient alternative to diesel and other fossil fuels, and just as importantly, a reliable energy source. Perhaps the most noteworthy aspect of the new eco-friendly solution, however, lies in its timeline. As SolarCity notes, “The microgrid — 1.4 megawatts of solar generation capacity from SolarCity and Tesla and 6 megawatt hours of battery storage from 60 Tesla Powerpacks — was implemented within just one year from start to finish.”

It’s a game changer for Ta’u residents, who can now rest easy knowing that their schools, law enforcement stations, and local businesses will constantly have the power they need to operate, and without killing killing anyone’s budget (or the planet), either. “It’s always sunny out here, and harvesting that energy from the sun will make me sleep a lot more comfortably at night, just knowing I’ll be able to serve my customers,” said Keith Ahsoon, whose family owns and runs one of the island’s food stores.

And with Ta’u as a case study for what is possible, the microgrid solution may soon find further opportunities for implementation. “Today, microgrid solutions featuring solar power and energy storage cost less than diesel almost anywhere in the world and are a cleaner, safer alternative,” SolarCity pointed out. “Solar and storage systems also eliminate expenses and issues associated with shipping diesel, and provide stable power costs for decades, unlike fluctuating fossil fuel prices — all by simply switching to the power of the sun.

CES 2023: HD Hyundai’s Avikus is an A.I. for autonomous boat and marine navigation
Demonstration of NeuBoat level 2 autonomous navigation system at the Fort Lauderdale International Boat Show

This content was produced in partnership with HD Hyundai.
Autonomous vehicle navigation technology is certainly nothing new and has been in the works for the better part of a decade at this point. But one of the most common forms we see and hear about is the type used to control steering in road-based vehicles. That's not the only place where technology can make a huge difference. Autonomous driving systems can offer incredible benefits to boats and marine vehicles, too, which is precisely why HD Hyundai has unveiled its Avikus AI technology -- for marine and watercraft vehicles.

More recently, HD Hyundai participated in the Fort Lauderdale International Boat Show, to demo its NeuBoat level 2 autonomous navigation system for recreational boats. The name mashes together the words "neuron" and "boat" and is quite fitting since the Avikus' A.I. navigation tech is a core component of the solution, it will handle self-recognition, real-time decisions, and controls when on the water. Of course, there are a lot of things happening behind the scenes with HD Hyundai's autonomous navigation solution, which we'll dive into below -- HD Hyundai will also be introducing more about the tech at CES 2023.

There's a scene in Mission Impossible 3 that you might recall. In it, our hero Ethan Hunt (Tom Cruise) tackles the movie's villain, holds him at gunpoint, and forces him to read a bizarre series of sentences aloud.

"The pleasure of Busby's company is what I most enjoy," he reluctantly reads. "He put a tack on Miss Yancy's chair, and she called him a horrible boy. At the end of the month, he was flinging two kittens across the width of the room ..."
