Solyndra, Solar Panels and Supersonic Planes: What's the Difference if One Fails?

Recently, the US government lost a few hundred million dollars on a new investment in a failed technology. But no one seemed to notice.

No, it was not the infamous Department of Energy's multi-hundred-million dollar loan guarantee to Solyndra, the now bankrupt California solar manufacturer and the latest Rorschach test about government support for clean energy. Many politicians criticized the government's investment in that venture, while clean energy advocates defended the investment as an experiment worth making.

Rather, the silent failure was a $320 million public investment in a new glider aircraft made by the Defense Department's advance research agency: DARPA. That new plane, the Falcon Hypersonic Technology Vehicle 2, crashed over the Pacific in early August. Built by Lockheed Martin, it was designed to deliver non-nuclear military strikes anywhere in the globe in less than an hour. The latest crash was not its first; it was the second failed flight experiment.

But after the repeated loss of the plane and a third of a billion in public dollars, the head of DARPA, the project's main public investor, Regina Dugan optimistically said, "We'll learn. We'll try again. That's what it takes."

This isn't the first time that a DARPA-funded project failed. A profile of DARPA a few years ago explained,

As former DARPA Director Charles Herzfeld noted in 1975, "When we fail, we fail big." Little has changed. According to (then) DARPA's current chief Piller, some 85%-90% of its projects fail to meet their full objectives. Still, Piller points out, DARPA "has been behind some of the world's most revolutionary inventions"... "the Internet, the global positioning system, stealth technology and the computer mouse."

DARPA's spectacular failure rate and noteworthy successes stem from its high risk ventures.

In contrast to the Solyndra backlash, after the news of this second DOD rocket failure and loss of hundreds of millions of dollars of public funds in that new technology, what did the critics say? Actually, nothing at all. Not one member of Congress openly criticized the latest DOD investment failure. Nobody said a word.

There was one reaction from a frequent writer about DARPA who praised its risk taking:

DARPA only undertakes projects that have a good chance of failing -- projects that few others dare to take on. Projects like hypersonic flight. The failure is not surprising; permission to fail is what has enabled the agency's spectacular success over its 53-year history.

So, the obvious question is: why the over-the-top criticism of this failed clean energy investment but an odd silence in the face of Defense Department projects which also fail quite spectacularly, expensively, and more frequently?

Apart from the usual political antics during the presidential election season, there might be a simple and troubling answer. The country has a fifty-year political consensus about technological risk taking to protect national security. Public defense investments are sacrosanct and encouraged. DOD clearly picks winners, and then sometimes fails, while trying not to pick losers. It is what government investment is about, and has guided billions of dollars of Defense spending over the years. (We have written previously about the myth that government should not "pick winners and losers.") At DOD, experimental failure is considered necessary to ultimate success.

But the same anti-government-investment politicians who go ballistic about one clean energy mistake fall mysteriously mute when multi-hundred million dollar DOD technology bets go wrong. No one rails that DOD is "picking winners and losers." There is no criticism at all. Except in cases of graft and incompetence, that is pretty much how the system of public investment should work at DOD.

For clean energy technology, there is not yet a political consensus like the one for defense technology that allows for trial and error. In clean energy, there is no Washington agreement for assuming any risks for increased investments to achieve future market share, to protect our national security, and or address foreign competition. Many politicians do not consider military and clean energy investment as similar "public goods" -- where the private sector won't take the risk in new technologies, and the government must invest to serve larger national goals that do not always deliver adequate private investment returns.

When all is said and done, this lack of political consensus on clean energy is the only difference between losing hundreds of millions on a failed solar investment and losing hundreds of millions on a failed defense aircraft.

In defense, failed spending is part of learning for success; in clean energy, any failure is proof that the whole public enterprise is a bust. That political disparity makes no sense.

In these tough economic times, no one wants to see the government lose money on failed technologies or companies. But giving multiple and necessary defense failures a pass, while harshly criticizing one clean energy flop, is a dangerous double standard. It is the kind of political hypocrisy that the country cannot afford if it is to achieve national security and a strong clean energy future.
