Exactly. There are cases where you want to subsidize wild and woolly ideas. If you have lots of money, then go ahead. But in many cases not everything will work. There are lots of good airplanes, Concorde being a case in point. It was a fantastic idea, but commercially it was not that great. Technologically, though, it certainly had an impact on the industry. Some of the ideas that were developed for that project, even though the project itself was not commercially all that successful, were used elsewhere. But you never know in advance. It becomes a policy decision.
If you can afford to put some money, not huge amounts, but some seed money into certain projects, then it becomes a choice. It's a business choice, almost. The government has to deal with it as a business. Eventually you have to sell these products. If there is no market for them that you can foresee, and the government cannot justify buying the product, then don't get into it.
