Using a toilet can pay for your coffee or buy you bananas at a university in South Korea, where human waste is being used to help power a building.

Cho Jae-weon, an urban and environmental engineering professor at the Ulsan National Institute of Science and Technology (UNIST), has designed an eco-friendly toilet connected to a laboratory that uses excrement to produce biogas and manure.

The BeeVi toilet - a portmanteau of the words bee and vision - uses a vacuum pump to send feces into an underground tank, reducing water use. There, microorganisms break down the waste to methane, which becomes a source of energy for the building, powering a gas stove, hot-water boiler and solid oxide fuel cell.

"If we think out of the box, feces has precious value to make energy and manure. I have put this value into ecological circulation," Cho said.

An average person defecates about 500g a day, which can be converted to 50 liters of methane gas, the environmental engineer said. This gas can generate 0.5kWh of electricity or be used to drive a car for about 1.2km (0.75 miles).

Cho has devised a virtual currency called Ggool, which means honey in Korean. Each person using the eco-friendly toilet earns 10 Ggool a day.

Students can use the currency to buy goods on campus, from freshly brewed coffee to instant cup noodles, fruits and books.

The students can pick up the products they want at a shop and scan a QR code to pay with Ggool.

"I had only ever thought that feces are dirty, but now it is a treasure of great value to me," postgraduate student Heo Hui-jin said at the Ggool market. "I even talk about feces during mealtimes to think about buying any book I want."

Indian Prime Minister Narendra Modi held talks with President of the Saudi Data and Artificial Intelligence Authority (SDAIA) President Dr. Abdullah Al-Ghamdi on the sidelines of the India AI Impact Summit 2026, reported the Saudi Press Agency on Friday.

Discussions focused on knowledge transfer and the exchange of expertise to accelerate digital development in both nations. They also tackled expanding bilateral cooperation in data and AI.

Al-Ghamdi commended India’s leadership in hosting the summit, noting that such international partnerships are essential for harnessing advanced technology to benefit humanity and achieve shared strategic goals.


India Chases 'DeepSeek Moment' with Homegrown AI

India Chases 'DeepSeek Moment' with Homegrown AI

Fledgling Indian artificial intelligence companies showcased homegrown technologies this week at a major summit in New Delhi, underpinning big dreams of becoming a global AI power.

But analysts said the country was unlikely to have a "DeepSeek moment" -- the sort of boom China had last year with a high-performance, low-cost chatbot -- any time soon, AFP reported.

Still, building custom AI tools could bring benefits to the world's most populous nation.
At the AI Impact Summit, Prime Minister Narendra Modi lauded new Indian AI models, along with other examples of the country's rising profile in the field.

"All the solutions that have been presented here demonstrate the power of 'Made in India' and India's innovative qualities," Modi said Thursday.

One of the startups making a buzz at the five-day summit was Sarvam AI, which this week released two large language models it says were trained from scratch in India.

Its models are optimized to work across 22 Indian languages, says the company, which received government-subsidized access to advanced computer processors.

The five-day summit, which wraps up Friday, is the fourth annual international meeting to discuss the risks and rewards of the fast-growing AI sector.

It is the largest yet and the first in a developing country, with Indian businesses striking deals with US tech giants to build large-scale data center infrastructure to help train and run AI systems.

On Friday, Abu Dhabi-based tech group G42 said the United Arab Emirates would deploy an AI supercomputer system in India, in a project "designed to lower barriers to AI innovation".

So-called sovereign AI has become a priority for many countries hoping to reduce dependence on US and Chinese platforms while ensuring that systems respect local regulations, including on data privacy.

AI models that succeed in India "can be deployed all over the world", Modi said on Thursday.

But experts said the sheer computational might of the United States would be hard to match.

"Despite the headline pledges, we don't expect India to emerge as a frontier AI innovation hub in the near term," said Reema Bhattacharya, head of Asia research at risk intelligence company Verisk Maplecroft.

"Its more realistic trajectory is to become the world's largest AI adoption market, embedding AI at scale through digital public infrastructure and cost-efficient applications," she said.

Another Indian company that drew attention with product debuts this week was the Bengaluru-based Gnani.ai, which introduced its Vachana speech models at the summit.

Trained on more than a million hours of audio, Vachana models generate natural-sounding voices in Indian languages that can process customer interactions and allow people to interact with digital services out loud.

Job disruption and redundancies, including in India's huge call center industry, have been one key focus of discussions at the Delhi summit.

Prihesh Ratnayake, head of AI initiatives at think-tank Factum, told AFP that the new Indian AI models were "not really meant to be global".

"They're India-specific models, and hopefully we'll see their impact over the coming year," he said.

"Why does India need to build for the global scale? India itself is the biggest market."
And Nanubala Gnana Sai at the Cambridge AI Safety Hub said that homegrown models could bring other benefits.

Existing models, even those developed in China, "have intrinsic bias towards Western values, culture and ethos -- as a product of being trained heavily on that consensus", Sai told AFP.

India already has some major strengths, including "technology diffusion, eager talent pool and cheap labor", and dedicated efforts can help startups pivot to artificial intelligence, he said.

"The end-product may not 'rival' ChatGPT or DeepSeek on benchmarks, but will provide leverage for the Global South to have its own stand in an increasingly polarized world."

Nvidia is on the cusp of investing $30 billion in OpenAI, scaling back a plan to pump $100 billion into the ChatGPT maker, the Financial Times reported Thursday.

The AI-chip powerhouse will be part of OpenAI's new funding round with an agreement that could be concluded as early as this weekend, according to the Times, which cited unnamed sources close to the matter.

Nvidia declined to comment on the report.

Nvidia chief executive Jensen Huang has insisted that the US tech giant will make a "huge" investment in OpenAI and dismissed as "nonsense" reports that he is unhappy with the generative AI star.

Huang made the remarks late in January after the Wall Street Journal reported that Nvidia's plan to invest up to $100 billion in OpenAI had been put on ice.

Nvidia announced the plan in September, with the investment helping OpenAI build more infrastructure for next-generation artificial intelligence.

The funding round is reported to value OpenAI at some $850 billion.

Huang told journalists that the notion of Nvidia having doubts about a huge investment in OpenAI was "complete nonsense."

Huang insisted that Nvidia was going ahead with its investment in OpenAI, describing it as "one of the most consequential companies of our time".

"Sam is closing the round, and we will absolutely be involved in the round," Huang said, referring to OpenAI chief executive Sam Altman.

"We will invest a great deal of money."

Nvidia has become the coveted supplier of processors needed for training and operating the large language models (LLM) behind chatbots like OpenAI's ChatGPT or Google Gemini.

LLM developers like OpenAI are directing much of the mammoth investment they have received into Nvidia's products, rushing to build GPU-stuffed data centers to serve an anticipated flood of demand for AI services.

The AI rush, and its frenzy of investment in giant data centers and the massive purchase of energy-intensive chips, continues despite signs of concern in the markets.
