The Iced Gems team came up with an ingenious new type of lock, which shuts off the power to appliances in your home when you lock the front door.
Ice Babes want high street clothing manufacturers to produce their collections using thermal fabrics. This would encourage people to turn their heating down by a degree or two, saving valuable energy. Making these eco-friendly clothing ranges VAT-free would make them affordable for consumers and show the government's commitment to saving energy.
'Food miles' are big news at the moment, but how can we tell how far our food has travelled to reach the supermarket shelf? Team Happy Feet's idea is to label all food products with an easy-to-read logo so that we can see the environmental impact of our food choices.
Team Acea Penguins want car drivers to understand the environmental impact of their journeys by fitting caron dioxide emission counters to all new cars.
Team CFC came up with a simple solution for reducing carbon emissions from car exhausts by fitting a high-tech filter.
The Zero Degrees team came up with the idea of using 'sleeping policemen' to generate electricity. Whenever a car drives over a speed bump it drives a turbine, which could generate enough electricity to power traffic lights and street lamps.
This team suggested using sulpher as a source of power as an eco-friendly alternative to coal.
What better solution to the problem of 'food miles' than growing veggies in your garden? This team proposed sending everyone some seeds as part of a campaign to encourage people to grow their own food.
This team came up with the idea of having a carbon credit card.
Aeroplanes are well-known pollutants, but this team suggested a new fuel source that could help reduce emissions from air travel - hydrogen.
This team invented the portable 'Eco-Stepper', which stores the energy generated whilst walking. It can then be plugged into the mains to supply power to your house.
This team invented the 'Charger' - a power pack that stores kinetic energy and can be used to power small electircal devices like mobile phones and MP3 players.
This team drew up impressive plans for an eco-friendly sports stadium, using recycled materials and renewable energy sources. Other ideas to transform the leisure and tourism industry include hydrofuel stations and a green hotel.
An ingenious water-saving device for the bathroom secured this team a place on the shortlist.
Using supermarket reward schemes as a model, this team suggested issuing recyling reward cards, with points on offer every time customers take packaging materials for recycling.
Chewing gum is an eyesore on every pavement in the UK, but this team created a tasty biodegradable gum made from beeswax.
This team focused on the energy generated by fitness fans in the gym. The 'Eco Gym' would harness this energy and convert it to electricity, reducing the demand for fossil fuels.
This team developed an idea for a system that uses sensors to automatically switch off appliances when there's no-one in the room.
This team built a great website (www.enuff.org.uk) to help explain their idea for a household energy-monitoring system.
This team invented a range of 'GlobalGreen' packs, which contain products to help consumers and businesses become more environmetally friendly.
This team combined a blind with a solar panel, and came up with a great idea for producing greener energy for every home and office.
'Grow more bamboo!' is this team's simple meesage. Bamboo is a seriously under-rated crop, which can be used to produce eco-friendly 'bio-plastics' and also produces 35% more oxygen than trees. An all-round winner!
Solar powered aeroplanes are this team's big idea. The power generated by huge solar panels on the plane's wings could supply all the plane's internal systems.
Green transport is the key to this team's idea. They've designed an eco-friendly car that runs on renewable energy sources.
Greenhouses are great for growing crops, but they can get a bit cold in winter. This team has designed a greenhouse powered by wind and solar energy, which stays warm all year round.
