Early Failures Sour Future Efforts. Energy Efficiency. 3D Printing.

That early failures sour future efforts is almost self evident. Mentioned in piece about 3D printing that failures (or weak successes) often sour further exploration. Various are working on getting barriers to success lowered. Better tools. Better examples. Better materials. Here is a Greentech article with a similar sentiment, on how low hanging fruit in energy efficiency might actually poison worthwhile efforts.
