Hi! I'm Dane Carlson, and welcome to the Business Opportunities Weblog. I've been publishing this website, by myself, and sometimes with the help of others for over twelve years now. You'll notice two things about this site right away:

  • We have tons of content. In fact, since November 2011, I've published more than 26,000 posts on thousands of different business ideas and opportunities.
  • We don't sell much advertising. In late 2013, I realized that by selling advertising, what I was really selling was my readers. In 2014, I've already radically cut down on the number of ads and will hopefully keep cutting.

Normally, when rain water lands on concrete, it pools or runs downhill until it reaches a storm drain that then pipes the water far away from the site of the initial downpour. This has a negative impact on the local groundwater, since rain is the primary way that groundwater stocks are replenished. A new concrete called pervious concrete that allows water to drain right through it, eliminating the need for drains. How will this change cities?

In the video below, watch as 1500 gallons of water is is drained right through the concrete.

NPR’s Science Friday has more.
