Japan to have 30 floating solar power islands to generate 60 megawatts of clean energy

Add as a preferred source on Google

Japan has about 146,000 square miles, which is roughly the size of the state of Montana. The difference is that while Montana is home to about 1 million people, Japan squeezes about 128 million people on its land. This lack of space creates a conundrum for a country that has ambitions to wean itself off of nuclear power and rely more on clean energy. Where can such clean-energy projects be built? On the water, according to Kyocera Corp. and Century Tokyo Leasing Corp.

The two companies are partnering to build two massive solar power islands that will float on two reservoirs (or “ponds,” as the announcement refers to them) and generate about 2.9 megawatts of energy.

One of the “water-mounted mega solar power plants” will be built to reside on the surface of Nishihira pond. It will generate about 1.7 megawatts of energy, which would make it the world’s largest floating solar plant, according to the announcement. The second floating solar power plant will be built on Dongping pond, and it will generate about 1.2 megawatts of clean energy. Work on this project is set to begin in September, with a target finish date of April 2015.

The combined 2.9-megawatt capacity of these two floating solar power plants would be enough to power anywhere between 483 to 967 American households, according to a Wolfram Alpha query.

The joint venture between Kyocera and Century Tokyo Leasing aims to eventually churn out 60 megawatts of solar power from 30 floating stations, each with about 2 megawatts of capacity, according to a spokeswoman quoted by Bloomberg.

Copenhagen could be a step ahead of Japan in terms of water-bound solar power machinations: The capital of Denmark may soon have giant solar paneled “energy ducks” floating in its harbor.

Apple Books apparently has the same knockoff problem as Amazon
WSJ's Joanna Stern says copycat AI books based on her work continue to pop up on the platform.

Apple Books has long been viewed as a cleaner alternative to Amazon's Kindle Store. But if a new investigation is anything to go by, it may be fighting the same battle against AI-generated junk. In a recent YouTube Shorts video, The Wall Street Journal's Joanna Stern revealed that fake, AI-generated versions of her book have repeatedly appeared on Apple Books, despite being reported and removed.

Your next EV battery could start life as a plastic water bottle
Penn State researchers have found a way to turn discarded PET plastic into battery-grade graphite.

Plastic bottles usually end up being recycled into lower-value products, buried in landfills, or worse, polluting the environment. But researchers at Penn State University believe they could one day power electric vehicles, smartphones, and even renewable energy storage systems after discovering a way to convert discarded plastic into high-quality battery graphite.

Anthropic's AI restrictions may finally be starting to thaw. After being forced offline earlier this month over U.S. government security concerns, the company's most advanced AI models are slowly making a comeback. According to a new report from Axios, Anthropic has already restored Mythos 5 for a limited number of trusted users, while Fable 5 could return as early as next week if ongoing discussions with federal agencies continue to progress.
