One of These Amazing Inventions Will Win the International Dyson Award Next WeekS

There are just four days until the international winner of the James Dyson Awards is announced from one of the following 15 finalists. Some amazing inventions are up for it, including that water sterilization bottle from the UK.

Check out the finalists in the video montage here, and fight it out in the comments below as to which one you think should win the award. I'm leaning towards the electric bike/trike hybrid, but the buoyancy aid from Australia is a novel idea also. [James Dyson Awards]

Minotaur Fire Nozzle System (New Zealand): Instead of holding a fire hose, the Minotaur Dire Nozzle is strapped onto fire-fighters with a harness. This counteracts the opposing water pressure and makes it easier to control.

Water Donut & Ultra Pipe (Germany): A pipe that purifies contaminated water with UV light. During sunless periods, the Ultra Pipe can filter the water through a pressure driven membrane.

Flo2w (Ireland): A new way of delivering oxygen to a hospital patient. The device is fitted on the patient's head using an adjustable headpiece. Flo2w is more efficient and comfortable than a big, intimidating one-size-fits-all mask.

Reanimations (Switzerland): A resuscitation vest that compresses a patient's chest as regular intervals and pushes the blood into the brain more effectively and evenly than with a manual cardiac massage

Butterfly Micro Scooter (Switzerland): Butterfly is a compact mobile micro scooter that can be folded away so it fits into a bag. When closed, dirty wheels are enclosed inside a smooth outer shell.

Seakettle (US): A life raft that provides shelter and fresh drinking water for those stranded at sea.

Mantis (US): A portable dental chair, that collapses into a trolley so it can be used to transport heavy equipment.

The Copenhagen Wheel (US): A sleek red hub in the rear wheel contains a motor, batteries and an internal gear system. It stores pedal power to power a hybrid electric motor – and can be controlled from a smart phone docked on the handlebars. Cyclists can use data to plan bike routes and see traffic and pollution levels ahead.

Tablet seed (Japan): A capsule made from water-soluble manure that contains vegetable seeds. When the tablet seed is buried in the ground, surrounding soil dissolves the capsule and chemical changes occur in the soil to promote growth.

Move-it (UK): A simple kit of self-adhesive cardboard parts, which the user sticks on to a cardboard box, turning it into a lightweight, easy-to-use trolley.

Air Free Intravenous infusions (UK): A drip chamber which prevents air entrainments in intravenous drip lines, reducing the chance of fatal air embolisms. It gives visual warning when an infusion has stopped.

Long Reach (Australia): A hand held device which expels a compressed emergency buoyancy aid up to 150 metres out to sea. Longreach helps people remain buoyant during an emergency situation.

BIQUATTRO (Austria): A pedal-assisted electric bike that can be turned into a tricycle when you need to carry a heavy load.

Wanderest seat (New Zealand): A seat designed to be strapped to public spaces such as a lamp post. It is portable so can be easily carried by the elderly.

Pure (UK): UV sterilization water bottle: a water bottle that filters and sterilises the water from a lake or a stream in two minutes. An outer chamber of the bottle is filled with dirty water from a lake, stream or puddle. The inner chamber plunges through the outer chamber, filtering water particles as small as four microns. Once the water is clear of sediment, it is sterilised for 90 seconds using a wind-up ultra violet bulb.
