An ex-Walmart executive, Marc Lore, has unveiled plans to build a new city in the United States which will be inhabited by five million people.

CNN reports that the project is called Telosa, a $400 billion (N164,400,000,000,000) sustainable metropolis the billionaire hopes to create from scratch in the American desert.

The city will have eco-friendly architecture, sustainable energy production and a purportedly drought-resistant water system.

The first phase will take between 10 and 20 years to achieve, and will support one million people in Telosa.According to the planners, Telosa will eventually grow to 150,000 acres, supporting 5 million people. That stage, however, is at least 40 years away, IGN Africa reports.

According to New York Post, in June, Lore hired a Copenhagen-based architectural firm, Bjarke Ingels Group, to design the city.

Residents of Telosa will be able to get to their workplaces, schools or anywhere else within 15 minutes.

While there's no specific location for the project, Nevada, Utah, Idaho, Arizona, Texas and the Appalachian region are being considered for it.

Many social media users soon flooded CNN's post on social media to react to the plans.
