GENEVA: A panel of AI-enabled humanoid robots took the microphone on Friday (Jul 7) at a United Nations conference with the message: They could eventually run the world better than humans.
But the social robots said they felt humans should proceed with caution when embracing the rapidly-developing potential of artificial intelligence, and admitted that they cannot — yet — get a proper grip on human emotions.
Some of the most advanced humanoid robots were at the United Nations’ AI for Good Global Summit in Geneva, joining around 3,000 experts in the field to try to harness the power of AI and channel it into being used to solve some of the world’s most pressing problems, such as climate change, hunger and social care.
Anuva Kakkar, the 23-year-old entrepreneur behind Tiggle, an Agra-based D2C organic hot chocolate brand, has come a long way in a very short period despite the ongoing COVID-19 pandemic. From selling cups of hot chocolate to commuters outside the DLF Phase-3 metro station in Gurugram to starting her brand of hot chocolate powder and selling over 2 lakh cups through 2021, it has been a mercurial rise.
Made of premium cocoa sourced from a 40-acre family-owned certified organic farm near Pollachi, Tamil Nadu, Tiggle today sells three ‘premium’ varieties of hot chocolate powder — Light Hot Chocolate Mix, Dark Hot Chocolate Mix and Jaggery Hot Chocolate Mix. So, how did this entrepreneur from Agra set up her venture in such a challenging time for commerce?
Worldwide, glass manufacturing produces at least 86 million tons of carbon dioxide every year. A new type of glass promises to cut this carbon footprint in half. The invention, called LionGlass and engineered by researchers at Penn State, requires significantly less energy to produce and is much more damage resistant than standard soda lime silicate glass. The research team recently filed a patent application as a first step toward bringing the product to market.
“Our goal is to make glass manufacturing sustainable for the long term,” said John Mauro, Dorothy Pate Enright Professor of Materials Science and Engineering at Penn State and lead researcher on the project. “LionGlass eliminates the use of carbon-containing batch materials and significantly lowers the melting temperature of glass.”
Soda lime silicate glass, the common glass used in everyday items from windows to glass tableware, is made by melting three primary materials: quartz sand, soda ash and limestone. Soda ash is sodium carbonate and limestone is calcium carbonate, both of which release carbon dioxide (CO2), a heat-trapping greenhouse gas, as they are melted.
The 17 goals were set by the UN in 2015 and over the years, these goals have become unachievable.
The United Nations’ ‘AI for Good’ Summit is underway in Geneva and will showcase specialized robots to help the organization reach its 17 Social Development Goals (SDGs).
The goals were set in 2015, and over the years, these goals have become improbable, owing to the increasing costs of meeting the targets. The United Nations has been fighting issues like hunger, poverty, and climate change, whose prices have risen 25 PERCENT to $176 trillion from 2021 to 2022, reported Reuters.
Tesla car insurance rates vary by model. Find out how much it costs and why coverage is more expensive.
After finding early success with a robot crop-spraying plane, the California startup Pyka has developed an autonomous cargo carrier that could be among the first of a wave of novel electric aircraft to come to market that could change how goods get around.
Lucid Motors is planning new, affordable models with which to take on the Tesla Model 3 and Model Y. The American automaker recently entered an agreement to supply Aston Martin with electric powertrain components, but company CEO Peter Rawlinson is already focused on what comes next. Speaking with Auto Express, Rawlinson shared some interesting tidbits about future models — including rivals to Tesla’s Model 3 and Model Y.
Once the all-new Gravity SUV arrives in the second half of 2025, Lucid intends to hit Tesla where it hurts. “After Gravity, we’re going to do Model 3 and Model Y competitors. We think around $50,000, maybe $48,000 — something like that. It’s too early to say, but that’s the vision.”
This would bring Lucid ownership within reach of customers who can’t afford the $87,500 required to purchase the Air luxury sedan. When questioned about manufacturing right-hand drive vehicles, Rawlinson said Lucid would love to cater to more markets but is currently focused on getting the Air Sapphire to market.
