China’s 5G user base is undoubtedly staggering, but pinning down a definitive number proves surprisingly tricky.

Here’s why:

Rapid Growth: China’s 5G expansion is truly phenomenal. Since commercially launching in 2019, subscriptions have skyrocketed, making it difficult to track the latest figures in real-time.
Varying Sources: Different organizations report slightly different numbers due to varying methodologies and reporting times. While estimates range from 400 million to 500 million users as of late 2023, the exact figure remains fluid.
Focus on Penetration Rate: Perhaps a more insightful metric is China’s 5G penetration rate. It’s estimated to be around 40-45% of the total mobile subscription base, which surpasses the global average and speaks volumes about the nation’s rapid adoption.
Focus on Regional Development: China’s 5G rollout prioritizes major cities first, gradually expanding into rural areas. Therefore, user numbers can vary significantly between urban and rural regions.

In conclusion, while the precise number of 5G users in China eludes a definitive answer, it’s undeniable that the nation is experiencing a meteoric rise in 5G adoption.

The focus should shift towards understanding the penetration rate and regional variations to paint a more nuanced picture of this dynamic landscape.

Additional points to consider:

China’s commitment to 5G infrastructure building and technological innovation continues, so user numbers are expected to keep climbing.
Understanding the diverse applications of 5G in China, from smart cities to industrial automation, adds another layer to the story.
Keeping an eye on future developments in China’s 5G landscape, including potential challenges and advancements, will be crucial for gaining a comprehensive perspective.

Remember, the focus should be on appreciating the scale and momentum of China’s 5G journey, without getting bogged down by the elusive exact number. This approach fosters a more insightful and informative understanding of this transformative technology in a global context.

Renewable Energy Concepts Can’t Violate the Laws of Physics

In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward.

I vividly remember a conversation with a guy in Maryland who was trying to explain the (ostensible) breakthrough that he and his team had made in hydrokinetics. When I was having trouble visualizing what we was talking about, he asked me to “think of it as a river in a box.”

“Oh!” I exclaimed. “You mean you take a box full of standing water, add energy to it get it moving, then extract that energy, leaving you with more energy that you added to it.”

“Exactly.”

I politely explained that the laws of physics, specifically the first and second laws of thermodynamics, make this impossible.

He wasn’t through, however, and insisted that, in his office, his people had constructed a “working model.”

Here’s where my tone descended into something less than 100% polite. I told him that he may think he has a working model, but he’s wrong; if he believes this, he’s ignorant; if he doesn’t, but is conducting this conversation anyway, he’s a fraud.

“But don’t you want to come see it?” he implored.

“No. Not only would not fly across the country to see whatever it is you claim to have built, I wouldn’t walk across the street to a “working model” of something that is theoretically impossible.”

—

I tell this story because the claim made at the upper left is essentially identical. You’re pumping water up out of a stream, and then claiming to extract more energy when the water flows back into the stream.

Of course, social media today is rife with complete crap like this. We’ve devolved to a point where defrauding money out of idiots is rapidly replacing baseball as our national pastime.
