Target Fixation.

 I just read this report about a new building insulation material that is waterproof and biodegradable.

Hang on a minute.. biodegradable? Just how long will it take to biodegrade? 5 years? 10 years? 20? 50?

Because I can bet a house will last a lot bloody longer than that.

To me it looks like the boffins were fixated on creating a biodegradable material without thinking if they should create one. Just what would the market be for such a material? 

I can only think temporary structures would be a viable market. Structures that only live a short life and are then torn down again. A bit of a niche market.

But biodegradable insulation for houses? Naaah!
