Birds ablaze: Solar farm is igniting, killing birds in flight

Hot spot: This solar farm in the Mojave Desert in California is igniting birds in flight at an alarming rate. Mirrors on the ground reflect super-hot light to the towers to be converted into electricity.

A huge solar energy farm in the Mojave Desert seems to be having one serious side effect: passing birds in flight are bursting into flames.

What's going on is that 300,000 mirrors on the ground are directing sunlight to huge towers that convert that energy into electricity. Bugs are attracted to the bright light from the mirrors drawing hungry birds to get into the path of the reflected light. And that concentrated light energy is causing the birds to catch fire, sometimes at a rate of one every two minutes. The flaming birds have been noticed since the plant powered up in February and its estimated that the total bird kill this year could top out at 28,000. Researchers estimated that one bird they found dead had been roasted by light beams that were nearly 1,000 degrees F.

Plans for building a second plant are on hold while investigators study the situation at the current site. What do you think? Is the potential of killing many birds a worthwhile cost for increased clean, "green" electricity?

If you actually read the Fish and Wildlife report, you will learn that the streamers are thought to be bugs and debris, not birds. The same report found only 47 birds found burnt by solar flux in a 1-year period.
