1 BTEC First Engineering Unit 1: The Engineered World © Pearson Education Ltd 2012. Copying permitted for purchasing institution only. New technologies Optical Fibres  Optical fibres are cables not metal but are thin strands of glass.  Communication signals (internet, phone etc) are sent down the glass by shining light which is reflected along the fibre.  They are able to send data at much faster speeds, with greater bandwidth. Much more information can be transmitted along the same size of cable.  Copper wire is easier to connect (Optical fibres are difficult to join easily) but are slower, heavier and carry less information BTEC First Engineering http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_p re_2011/radiation/sendingrev1.shtmlhttp://www.bbc.co.uk/schools/gcsebitesize/science/aqa_p re_2011/radiation/sendingrev1.shtml http://en.wikipedia.org/wiki/Optical_fiber https://www.youtube.com/watch?v=0MwMkBET_5I

Otherwise getting the Hydrogen in the first place can use fossil fuels and cause climate change

3 BTEC First Engineering Unit 1: The Engineered World © Pearson Education Ltd 2012. Copying permitted for purchasing institution only. New technologies Surface nanotechnology  Surface NanoTechnology is where a microscopic coating is applied to surfaces so that nothing sticks to them  Self cleaning windows can be made this way so that even though dust and dirt may land on the glass, whenever it rains they will wash off on their own  The big advantage is not having to pay window cleaners or put up with dirty windows  However there is a cost involved in applying the coating in the first place.

4 BTEC First Engineering Unit 1: The Engineered World © Pearson Education Ltd 2012. Copying permitted for purchasing institution only. New technologies Telematics  GPS, Mobile Telecommunications and ICT combined to track and manage the location of Cars and Trucks  GPS = Global Positioning System  Helps with: Navigation, Logistics (making sure the right vehicles are in the right place at the right time) and communication BTEC First Engineering

5 Unit 1: The Engineered World © Pearson Education Ltd 2012. Copying permitted for purchasing institution only. New technologies Blended Wing Bodies  Advanced aircraft designs consisting of large aerofoil wings joined to an aircraft body.  different from ‘flying wing’ designs. These aircraft have a distinct wing and body, although much more aerodynamic than existing designs.  Reduce fuel costs. Combined with lightweight composite materials for maximum fuel efficiency BTEC First Engineering

6 Unit 1: The Engineered World © Pearson Education Ltd 2012. Copying permitted for purchasing institution only. New technologies Bionics  small electronic devices can be used for medical purposes to improve the medical condition of individuals.  A pacemaker fitted to regulate a person’s heartbeat is a good example.  Prosthetic Limbs with electronic motors or bluetooth control BTEC First Engineering
