SASEBO, Japan (AP) — The English-speaking receptionist is a vicious-looking dinosaur, and the one speaking Japanese is a female humanoid with blinking lashes. “If you want to check in, push one,” the dinosaur says. The visitor still has to punch a button on the desk, and type in information on a touch panel screen.
From the front desk to the porter that’s an automated trolley taking luggage up to the room, this hotel in southwestern Japan, aptly called Weird Hotel, is “manned” almost totally by robots to save labor costs.
Hideo Sawada, who runs the hotel as part of an amusement park, insists using robots is not a gimmick, but a serious effort to utilize technology and achieve efficiency.
Henn na Hotel, as it is called in Japanese, was shown to reporters Wednesday, complete with robot demonstrations, ahead of its opening to the public Friday.
Another feature of the hotel is the use of facial recognition technology, instead of the standard electronic keys, by registering the digital image of the guest’s face during check-in.
The reason? Robots aren’t good at finding keys, if people happen to lose them.
A giant robotic arm, usually seen in manufacturing, is encased in glass quarters in the corner of the lobby. It lifts one of the boxes stacked into the wall and puts it out through a space in the glass, where a guest can place an item in it, to use as a locker.
The arm will put the box back into the wall, until the guest wants it again. The system is called “robot cloak room.”
Why a simple coin locker won’t do isn’t the point.
“I wanted to highlight innovation,” Sawada told reporters. “I also wanted to do something about hotel prices going up.”
Staying at Henn na Hotel starts at 9,000 yen ($80), a bargain for Japan, where a stay in one of the nicer hotels can easily cost twice or three times that much.
The concierge is a doll-like hairless robot with voice recognition that prattles breakfast and event information. It cannot call a cab or do other errands.
Japan is a world leader in robotics technology, and the government is trumpeting robotics as a pillar of its growth strategy. Robots have long been used here in manufacturing. But interest is also high in exploring the potential of robots in human interaction, including helping care for the elderly.
Robotics is also key in the decommissioning of the three reactors in Fukushima, northern Japan, which went into meltdowns in 2011, in the worst nuclear catastrophe since Chernobyl.
One area Henn na Hotel still relies on human beings is security.
The place is dotted with security cameras, and real people are watching everything through a monitor to make sure guests stay safe and no one makes off with one of the expensive robots.
“And they still can’t make beds,” said Sawada, who has also engineered the rise of a popular affordable Japanese travel agency.
He has big ambitions for his robot hotel concept and wants to open another one soon in Japan, and later abroad. He is also eager to add other languages, such as Chinese and Korean, to the robots’ vocabulary.
A block-shaped robot that was scuttling around in the lobby had been brought in to do room service, delivering beverages and simple snacks. But it wasn’t ready to do that yet.
Outdoors, Sawada also demonstrated a drone that flew in to deliver a few small jars filled with snacks. He said he wanted to eventually have drones perform in shows for guests.
In the hotel’s rooms, a lamp-size robot in the shape of a fat pink tulip called Tuly answers simple questions like, “What time is it?” and “What is the weather tomorrow?”
You can also tell it to turn the room lights on or off. There are no switches on the walls.
Sawada is keeping the hotel half-filled for the first few weeks to make sure nothing goes wrong.
He also canceled at the last minute the overnight stay planned for media. The robots simply weren’t ready.

In a world where technology plays an increasingly central role in all aspects of life, the importance of Science, Technology, Engineering, and Math (STEM) education cannot be overstated. Recognizing the significance of STEM for the future, focusing on young women and girls is a critical step in achieving gender equality and empowering the next generation.
Self-eSTEM, an Oakland-based non-profit organization, was founded by Adamaka Ajaelo, an Oakland native who had a successful corporate career with several Bay Area technology and non-tech companies. Ajaelo boldly decided to step away from these companies to give 100% of her time and talent to the non-profit organization she started in 2014 in the belief that she can change the game in innovation and future STEM leaders.
Over the course of a decade, Ajaelo has provided futurist tech programming to more than 2,000 BIPOC women and girls. The organization has an Early STEM Immersion Program for ages 7-17, Emerging Leaders Workshops for ages 18-25 and volunteer network opportunities for ages 25 and up.
In January 2025, Self-eSTEM will launch digital and generative AI programming, which provides digital literacy and AI literacy training through an entrepreneurial project-based activity. This programming will be a hybrid (i.e. in-person and online). Additionally, thanks to a grant from Comcast, in spring 2025, the organization will have a co-ed series for middle and high school students.
While the organization’s programs center on innovation and technology, participants also gain other valuable skills critical for self-development as they prepare for a workforce future. “Self-eSTEM encourages young women to expand on teamwork, communication, creativity, and problem-solving skills. The organization allows young women to enter STEM careers and pathways,” said Trinity Taylor, a seventh-year innovator.
“Our journey over the last decade is a testament to the power of community and opportunity, and I couldn’t be more excited for what the future holds as we continue to break barriers and spark dreams,” said Ajaelo.
“By encouraging girls to explore STEM fields from a young age, we foster their intellectual growth and equip them with the tools needed to thrive in a competitive global economy,” Ajaelo says.
Empowering young girls through STEM education is also a key driver of innovation and progress. When young women and girls are encouraged to pursue careers in STEM, they bring unique perspectives and problem-solving approaches to the table, leading to more diverse and inclusive solutions. This diversity is crucial for driving creativity and pushing boundaries in scientific and technological advancements.
Self-eSTEM has fundraising opportunities year-round, but year-end giving is one of the most critical times to support the program. Visit www.selfestem.org to donate to the organization, as your generosity and support will propel programming support for today’s innovators.

California was chosen by the U.S. Department of Commerce (Commerce) and Natcast, the operator of the National Semiconductor Technology Center (NSTC) to be home to the headquarters for the National Semiconductor Technology Center – as part of the Biden-Harris Admin’s CHIPS and Science Act.
The CHIPS for America Design and Collaboration Facility (DCF) will be one of three CHIPS for America research and design (R&D) facilities and will also operate as the headquarters for the NTSC and Natcast.
“We are thrilled that the Department of Commerce and Natcast chose to locate this critically important facility in Sunnyvale, the heart of the Silicon Valley, alongside the world’s largest concentration of semiconductor businesses, talent, intellectual property, and investment activity,” said Dee Dee Myers, Senior Economic Advisor to Gov. Gavin Newsom and Director of the Governor’s Office of Business and Economic Development (GO-Biz). “The Newsom Administration and our partners across the industry know how important it is to shorten the timeframe from R&D to commercialization.”
According to GO-Biz, the DCF is expected to direct over $1 billion in research funding and create more than 200 employees in the next decade. The facility will serve as the center for advanced semiconductor research in chip design, electronic design automation, chip and system architecture, and hardware security. The CHF will be essential to the country’s semiconductor workforce development efforts.
As detailed in the released NSTC Strategic Plan, the DCF will suppress the obstacles to “semiconductor prototyping, experimentation,” and other R&D activities that will enhance the country’s global power and leadership in design, materials, and process innovation while enabling a vigorous domestic industr“Establishing the NSTC headquarters and design hub in California will capitalize on our state’s unparalleled assets to grow a highly skilled workforce and develop next-generation advancements,” stated U.S. Sen. Alex Padilla (D-Calif.). “This CHIPS Act funding will propel emerging technologies and protect America’s global semiconductor leadership, all while bringing good-paying jobs to our state.”

Advanced Conductors Provide Path for Grid Expansion
Utility companies in the United States could double electric transmission capacity by 2035 by replacing existing transmission lines with those made from advanced materials, according to a new study published Monday in the Proceedings of the National Academy of Sciences.

Utility companies in the United States could double electric transmission capacity by 2035 by replacing existing transmission lines with those made from advanced materials, according to a new study published Monday in the Proceedings of the National Academy of Sciences.
Led by Duncan Callaway, professor and chair of the Energy and Resources Group (ERG), and Amol Phadke, an affiliate and senior scientist at the Goldman School of Public Policy, the first-of-its-kind study details a faster and more cost-effective way to expand the grid and connect the more than 1,200 gigawatts of renewable energy projects awaiting approval. The analysis was first published last December as a working paper by the Energy Institute at Haas and has been covered by the New York Times, the Washington Post, Heatmap News, and other news outlets.
“Expanding transmission capacity is critical to decarbonization, and we sought to study ways to build it faster and cheaper,” said Callaway.
It currently takes 10 to 15 years to build a new power line and the U.S. is building transmission lines at a lower rate than it was in the past decade. Without sufficient capacity, renewable energy projects often sit in limbo for years as transmission operators study what upgrades—if any—are needed to accommodate the increased loads.
The authors modeled various scenarios to determine if replacing existing transmission conductors with those made with advanced composite-core materials—a process known as reconductoring—could provide a pathway to faster grid expansion.
Several reconductoring projects have been initiated in Belgium and the Netherlands, and utility companies in the U.S. have used the material to string transmission lines across wide spans like river crossings. That technology, however, has not made its way to the majority of overhead power lines that feed residential and commercial customers.
“As we learned more about the technology, we realized that no one had done the detailed modeling needed to understand the technology’s potential for large-scale transmission capacity increases,” said Phadke.
Based on the authors’ projections, it is cheaper—and quicker—for utility companies to replace the 53,000 existing transmission lines with advanced composite-core materials than it is to build entirely new transmission lines.
They assert that doing so would reduce wholesale electricity costs by 3% to 4% on average—translating to $85 billion in system cost savings by 2035 and $180 billion by 2050.
“The level of interest we’ve received from federal and state agencies, transmission companies and utilities is extremely encouraging, and since our initial report, the Department of Energy has committed hundreds of millions of dollars to reconductoring projects,” said co-author Emilia Chojkiewicz, a PhD student in ERG and an affiliate of the Goldman School of Public Policy. “We are looking forward to learning about these projects as they unfold.”
Additional co-authors include Nikit Abhyankar and Umed Paliwal, affiliates at the Goldman School of Public Policy; and Casey Baker and Ric O’Connell of GridLab, a nonprofit that provides comprehensive technical grid expertise to policy makers and advocates.
