Bobcat unveils quiet, electrically powered excavator

One of the noisiest of America’s largest industries is construction and maintenance. It turns out that industry has the lowest “reinvestment rate,” i.e., spending on innovation, research, and development, of any major industry in the country. So resistance to innovation and change is deeply entrenched. But sometimes, change happens despite industry resistance. That’s what happening at Bobcat, which has teamed up with another company to unveil an electrically-powered

We want to congratulate our sister program, Quiet Communities, which pioneered a change-management approach specifically to accelerate the rate of change in one deeply change-resistant industry, outdoor power equipment. For six years Quiet Communities has been fighting to get outdoor power equipment manufacturers and users–the companies that build and use gas-powered equipment, including those leaf blowers we all love to hate–to adopt new, cleaner and quieter electrically-powered equipment. Now its happening.

We call this approach “technology pull,” which is how America has always gone about achieving large-scale, systemic change. Essentially, new technologies come along, sometimes whole clusters of them.  Examples include railroads, electricity, telegraph, telephone, gasoline engines, aircraft, radio, television, and the like. All of those were all part of one gigantic, historic wave called the industrial revolution.

And now we’re living through the post-industrial revolution driven led by information technology and the emergence of alternative energy sources like electric motors. Arguably, America’s “secret sauce,” the way this country built the world’s most powerful economy, has always been by encouraging engineers and technologists to invent the next big thing faster than anybody else.

And now, finally, America’s change-resistant, stubbornly resistant outdoor power equipment manufacturers are getting the message. Congratulations to them! I have no stake in this innovation partnership between Bobcat and Green Machine, other than our own goal of making America a cleaner, quieter place to live. But frankly, I’m thrilled to see this happen.

Now if only we could convince the federal government to let the aircraft industry move faster toward electrically-powered airplanes (about which we’ve written already), then maybe we can all look forward to seeing a quieter, less polluted future ahead of us.
