Clip about biomimicry I saw at school last year, very interesting!
Biomimicry is not copying nature directly, it's about being inspired by nature.
It's a powerful way to innovate, by using analogies of principles of nature when they're advantageous in the context you're working in.
This clip is from 2007, but biomimicry is still evolving.
On asknature.org you can type in a problem you want to solve and you get examples of how nature deals with it.
Example of biomimicry
Termites build mounds in which they maintain the temperature inside to within one degree, even if the outside temperature varies from 42°C to 3°C. The Eastgate Building, an office complex in Harare, Zimbabwe, has an air conditioning system modeled after this principle of termite building. Eastgate uses 90% less energy for ventilation than conventional building its size.
