The script was just a proof of concept. A scenario where you could be paid to donate 1% of your CPU time while certain webpages were open will never occur. Here's why:
Let's say there exists a problem where it's worth paying to solve it like this. The most a company could pay you is just below the spot price for buying instances on EC2 or some other cloud/cluster -- or they'd do that instead. So we're talking about nickels and dimes per hour for the equivalent of 100% CPU time on an EC2 instance.
If you donate the equivalent to 1% of that computational power, the most you can earn is hundredths of a penny per hour. You could run the script for a week and make a penny, while spending more than a penny on extra electric. That's no net gain for you, and no meaningful work done for the script author -- so this script would never have been written.
