New Technology
Optical FibresTransmit data through glass fibres.
The information travels AT THE SPEED OF LIGHT!!!
Advantages over wire:•Transmit data at higher speeds.• Transmit data digitally, with less errors.
Hydrogen Fuel Cells

HYDROGEN OXYGEN WATER= +
Hydrogen Fuel CellsThey 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 CellsWhere are they used?
Blended Wing BodiesBoeing –
Present….
Boeing – Future?
Blended Wing BodiesIt’s not the first…
The Westland Dreadnaught.First flight = 1924Last flight = 1924
Blended Wing BodiesBy 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.
BionicsUsing 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’.
BionicsPacemaker: Keeps the heart beating at a normal rate electronically.
Surface Nano TechnologiesNano Technology is changing materials at an atomic level!
Surface Nano Technologies1 Nano = 1 Billionth of a metre…..
The average Y9 student = 1200 million nanometers tall!
Surface Nano TechnologiesSurface 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 TechnologiesCeramics – Hygienic surfaces that germs cannot attach to.
Surface Nano TechnologiesMetals – That do not corrode. RUST!
Surface Nano TechnologiesGlass / Plastic – That is easy to clean!
Surface Nano TechnologiesTextiles – That don’t get wet…
TelematicsUsing 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.
