This is an old story. I ran into the story fifty years ago in a spiel pumping up a planned 'utopia' south of Minneapolis.
Same story, clean energy and transportation (yes that was a thing in the 70's) with a planned walkable downtown. Planned neighborhoods with mixed housing to build community.
The truth is another pile of money bought some farmland to rip up into a suburb for the bay area and the state capital. Commute by light rail. It is advertised as a utopia to generate sales just like the Apple Valley MN sales talk I heard fifty years ago was.

Not
"operated using clean energy, that would create thousands of jobs while offering residents reliable public transportation and urban living"
This all reminds me of the article featuring a twenty one year old Donald Trump that I read about that time. He was saying how he was going to save the world through peace, love, and real estate.
And where is the 'utopia' now?

Utopia or the death throws of capitalism?
A group of rich people has money and money under capitalism has to grow. In our system that is the way it is. Money piles must be invested to make new money piles. Ad infinitum in a random walk called progress.
Now money piles have grown so large they want to build whole cities. This indicates trouble, not prosperity.
This is the mindless march of capital. Capital that has pressed Silicon Valley Royalty into its service.
Another business model is called a utopia. What's new? Will this utopia have universal health care?
Does this utopia change the relationship of city dwellers to the means of production?
I do not think so! But like Apple Valley it will have plenty of addiction services. And customers for them.
