A large proportion of the energy we produce disappears
unused into thin air via waste heat. Tiny thermoelectric generators can tap
this potential, whereby the electricity is produced by way of temperature
differences. However, so far their production has been laborious and expensive.
At the same time there is a lack of suitable materials. At the Hannover trade
fair researchers are now presenting a new manufacturing process with which
these generators can be cost-effectively produced in the form of large-area
flexible components from non-toxic synthetic materials (hall 3, booth D25).
