Redesign of transport

 

I have redesigned a train and I added solar panels and some LED lights and a battery pack. The solar panels will catch light from the sun allowing the train to move instead of the old fashioned way of moving by rail. The LED lights are to light the way in the dark and are more energy efficient and use less electricity compared to ordinary light bulbs. The battery pack is used to store the extra solar energy when its not being used or at night otherwise the extra solar power will go to waste. The train is made from recycled metal this is more environment friendly because it saves natural ore and reduces energy and resources that go into mining metal also reducing emissions and greenhouse gases. Electric cars are quiet and electric trains are quiet so my redesign doesn't disturb the environment by being noisey.

Steam challenge food packaging

My food packaging is environmentally friendly because its reusable so that means you can use the same container over and over again. A plastic container can last for 5 to 10 years and at the end of its life you can recycle it. I also thought of some other ideas like:

Corn husks 
Taro Leaves
Harakeke bag
Plastic container 
Paper bag
Glass jar 
Beeswax wrappers

These might also be good ideas for food packaging.

Elephants electric tooth brush design

 

Elephants have 26 teeth including their tusks so I have included 24 small brushes for their molar teeth and two extra large brushes on the outside that will clean their tusks. My design has a soft gel mouth guard so it doesn't hurt the elephants mouth it also is very quiet so it does not scare the elephants. It has a long handle for the zoo keepers to reach up high to brush their teeth. The shape is like a mouth so it fits nicely insides the elephants mouth.
