Abu Dhabi-Backed Tech Sculpture To Be Installed In Houston
Created for the LAGI 2019 design competition in Abu Dhabi, the high-tech installation will double as a renewable power plant.
“The world’s largest sundial”, designed by Berlin architect Riccardo Mariano, is set to be installed in the city of Houston, Texas, in the city’s East End neighborhood in 2024.
The project was made possible by the Land Art Generator Initiative partnership with Masdar City, an Abu Dhabi urban development dedicated to creating sustainable cities and lifestyles. For those unaware, Houston, Texas, is twinned with the capital of the United Arab Emirates, hence the connection.

The 30-meter-tall sundial will be known as the Arco del Tiempo (Arch of Time) and functions as an interactive clock, casting sunlight onto the surface of Guadalupe Plaza Park. The installation’s geometry, carefully designed according to Houston’s latitude and longitude, is accurate throughout the seasons and hours of the day.

However, the Arco del Tiempo is far more than just a sculpture. The project will also serve as a renewable energy power generation plant. The finished arch will incorporate solar modules on its south-facing side, generating around 400 megawatt-hours of electricity annually — the equivalent energy consumption of 40 local homes.

“It was a pleasure to be part of the LAGI competition in 2019, and we’re very excited to see the winning entry come to life—particularly in Abu Dhabi’s sister city,” said Chris Wan, Associate Director of Sustainability and Corporate Social Responsibility at Masdar City. “We know that public art plays a significant role in the fabric of a city, and Arco del Tiempo is so much more than public art: it will also educate the public about sustainability while celebrating and advocating for it. It’s a powerful combination. I hope to see more art like it in the cities of the future”.
Over its lifetime, the Arco del Tiempo is projected to generate over 12 million kilowatt-hours of renewable energy, effectively removing 8,500 metric tons of CO2.

At I/O 2026, Sundar Pichai Concedes AI Must Deliver Real Value
Gemini 3.5, a personal agent called Spark, agentic shopping, and Android XR eyewear are all aimed at making AI feel useful, not just impressive.
Google’s annual I/O developer conference (I/O 2026) has recently become a status update on the same question: can the company turn its AI spending into products people use every day? This year, chief executive Sundar Pichai described Google as being in a phase of hyper progress, while conceding this is the part of the cycle where people want to see real value in the products they use on a day-to-day basis.
The strategy on display was to push agents — AI systems that act on a user’s behalf — into nearly every Google product at once. Search now has an “intelligent search box” that returns generated explainer videos alongside links. Gmail, Docs, YouTube and Maps are gaining their own agent layers, including a Docs Live feature that turns spoken instructions into drafted text with citations.
Two new models, Gemini 3.5 and a cheaper Gemini 3.5 Flash, arrived the same day. Google says 900 million people now use Gemini, and that more than 50 billion images have been generated with it. The pricing tier names are likely to confuse buyers: a new AI Ultra plan launches at $100 a month, while the older Gemini AI Ultra drops from $250 to $200.
The flashier announcements were Gemini Omni, a video generator pitched as a more realistic answer to OpenAI’s discontinued Sora 2, and Gemini Spark, a personal agent that handles recurring tasks across a user’s Google account. A new universal shopping cart lets agents complete purchases across multiple retailers from inside Google itself, placing the company between the merchant and the buyer, and also owning the checkout.

Google also confirmed its Android XR eyewear, built with Samsung and frames from Warby Parker and Gentle Monster. Audio-only glasses ship this autumn; a display-equipped version, which would superimpose live translations into the wearer’s field of view, is still in development. Both sets translate, however only the display version shows you the result.
What Pichai did not resolve is the bargain underneath all this. An agent is only useful to the degree it knows your calendar, your inbox, your shopping history and your physical surroundings. Google has now confirmed that, in time, the same context may carry advertising.
