New Technology

Optical Fibres Transmit data through glass fibres. The information travels at the speed of light. Advantages over wire: Capacity to transmit more data Transmit data digitally, with less errors.

Hydrogen Fuel Cells + = WATER HYDROGEN + OXYGEN =

Hydrogen Fuel Cells They convert the oxygen and hydrogen to into electricity. They are quiet and efficient. Simple to produce as not many moving parts. Cheap to mass produce. Water is only waste product. Expensive materials!

Hydrogen Fuel Cells How does it work? Oxygen They just want to get together and make water!

Hydrogen Fuel Cells + - How does it work? Hydrogen Oxygen The catalyst (platinum) It splits the Hydrogen into + and -

The + can pass through the wall. Hydrogen Fuel Cells How does it work? + Hydrogen Oxygen The + can pass through the wall.

The – must go around the wall. Hydrogen Fuel Cells How does it work? + Hydrogen Oxygen - The – must go around the wall.

Hydrogen Fuel Cells + + + + + - - - - - - - - How does it work? Oxygen + + + - - - - - - - - The electrons travels around the wall along a wire

Hydrogen Fuel Cells W A T E R + + + + + - - - - - - - - How does it work? W A T E R + + Hydrogen Oxygen + + + - - - - - - - - Where they join with Oxygen to make…….. WATER!

Hydrogen Fuel Cells W A T E R + + + + + - - - - - - - - How does it work? W A T E R + + Hydrogen Oxygen + + + - - - - - - - - The flow of electrons is………….. ELECTRICITY!

Hydrogen Fuel Cells Where are they used?

Blended Wing Bodies Boeing – Present…. Boeing – Future?

Blended Wing Bodies It’s not the first… The Westland Dreadnaught. First flight = 1924 Last flight = 1924

Blended Wing Bodies By joining the body and the wings, you can reduce drag, making it more efficient to travel through the air. Improves fuel efficiency Combined with composites to produce very light and smooth vehicle body shapes.

Bionics Using electronics to solve medical problems.

1. Electrodes fitted to the shoulder harness detect electrical impulses from the nerve endings. 2. A computer processes the impulses and makes the arm control move. 3. Force monitors on the hand detect pressure and send a signal to the patients chest. The chest has the nerves that would have been used attached to it, so the patient can ‘feel’.

Bionics Pacemaker: Keeps the heart beating at a normal rate electronically.

Surface Nano Technologies Nano Technology is changing materials at an atomic level!

Surface Nano Technologies 1 Nano = 1 Billionth of a metre….. The average Y9 student = 1200 million nanometers tall!

Surface Nano Technologies Surface Nano Technology changes the atomic structure of a material so that the surface is improved. What is it used for? HOLD ON TO YOUR SOCKS!!!!

Surface Nano Technologies Ceramics – Hygienic surfaces that germs cannot attach to.

Surface Nano Technologies Metals – That do not corrode. RUST!

Surface Nano Technologies Glass / Plastic – That is easy to clean!

Surface Nano Technologies Textiles – That don’t get wet…

Telematics Using ICT and science to improve the communications sector. For example: Global Positioning Systems (GPS) The location of vehicles can be monitored all over the world.
