Only about 30% of commercial development projects make it to market.

It's hard to predict what the market will want at the point where you 
can expect to have got the product developed, and if somebody comes up 
with a better way of doing the job while you are developing yours.

If the idea looks nutty when you start the development, it's unlikely to 
look less nutty in six months time (or however long it takes you to get 
it to work).

US venture capital is reputed to work on the principle that about one 
project in twenty will pay off generously enough to cover the costs of 
the projects that failed or were only marginally profitable.

A more sensible approach is to look for niche markets where you can make 
a lot out of a few machines which you can afford to cobble together in
small numbers out of mostly bought-in parts, and then invest heavily in 
making the machines more cheaply in higher volumes.

The US pioneered solar cell manufacture, but never bothered to produce 
them in high volume. Germany invested a lot in making them in ten times 
higher volume than anybody else in the late 1990s, which let them halve 
the unit price and dominate the market for a few years.

About a decade or so ago, China pulled off exactly the same trick, which 
called for a much bigger investment, and they've now got about 90% of 
the world market - and solar cells now make the cheapest electric power 
you can buy.

America likes to think that it invented the modern industrial state, but 
it doesn't know as much as it should about the rest of the world.
