A crash course in changing the world.
We use our phones everyday. It needs battery to use it, so i have thought about how to charge a new battery. My idea was to make a shoes that has a battery under the shoes and when we make a step it will generate power by heat and by the pump. It's simple, we just need to wear the shoes like this and walk for long time and when it gets low battery, we just need to take of the battery under the shoes and change it.…Continue

This current world, the solar power is attracting much attention. Some country are selling the solar cells, but poor people can' buy the solar cells. In addition, the solar cell's cost is too expensive. I think the thing that can do with sunlight without the solar cell, and I have an idea the can do it. It's when we heat the food. We can heat by oven or stove, but the poor people can't have it. Poor people have to cut the tree and they heat the food. If there is a mistake, their house can…Continue

Light is needed even when its not dark, some houses don't have enough windows to allow enough sunlight in. We privilege people have access to light bulbs and unlimited amount of electricity, therefore we people do not consider the gratefulness of light in our daily life. Have you ever thought about the people living in slums who don't have access to enough electricity? People in poverty can't eve afford a new light bulb, because it costs 6.02 dollars while they earn less than a dollar a…Continue
This is act stage and my job is to try to find new way to power something I use every day. Everyday, I use fan and light and the sport that I play is basketball. When I think about what I use everyday, I connect it with what I do everyday. Then, with what I thought of, I use fan, light and I play basketball everyday. I thought of powering fan and light while I'm playing basketball.
This is a drawing of how the new way work:…Continue

Since I have 3 dogs in my house and they excrete everyday. I suddenly thought of "Why don't we reprocess dog's poo to create electricity, power generator or fuel?"
FACTS ABOUT POOP:
-As you know poop is usually used as a fertilizer and now we can create fuel from poop.
-Poop produces Bio-gas and we can produce electricity and heat because biogas is rich in methane.
-1.350 tonnes of dog poop made every day in Australia.
-Farmer can saves $200,000 with poo…

Task for LEARN3 was to design a new to power something we use everyday. We use lots of different things everyday, starting from electronic gadgets to transportation, which requires energy. Thus, we have to come up with some way to generate them in different way. What I came up with is to generate a desk light from the energy that is produce by hamster wheel. Hamster loves to play on hamster wheel. It spins and spins, it can generate lots of energy. There are usually at least 2 hamsters each…Continue

Oven or stove are too expensive for poor people. Once it's broke, it's hard to repair it and guarantee it will safe like before. The energy that we need to cook on it also not free, sometimes we need to cut down trees and buy gas that if you drop it, it will explode. Therefore, fuel will run out if we don't use it properly and deforestation will extinct trees that aged more than hundred years. I'm thinking that we can change those problems. Solar cooker can help those poor people. The energy…Continue

The task of this blog post is designing a new way to power something. Almost everyday, I go and get home from outside school lessons using my bike, and I always get home at 7.00 pm. So, its going to be dark at 7.00 and I dont have something to light my path. I am thinking to design a very mainstream bicycle dynamo by using the wheels to power the light. But then, I decided to change the power source. The new power source that I want to use is the wind. I decide to use wind because every time…Continue

My first step to make difference is by tell my friends and people near me that water is really important for daily needs. More than billion people can't access to clean drinking water. Almost everyday children are dying because of it. Which is why I'm going to tell them the first move that they can change those problems. I created a poster that said "2.5 billion people worldwide do not have access to clean water. Mostly, 5 billion children are die causes of water illness. We can take the…Continue
I have found a cool guide on how to make your own solar powered USB charger (to charge cell phones or anything else that usesUSB): http://www.instructables.com/id/Solar-Altoids-USB-Charger/
I'm going to give this a shot when I get the chance and hope that I don't blow something up!

The thing I use the most during the day is my computer because most of my school work involves something on the internet. I think the best thing I could do is have battery cell that could be charged in multiple ways like by riding a stationary bike and solar power.

Celllphones. They are something that almost everyone has. Some teens are texing non stop! Some take up a lot of power especially if they have to be charged everyday. They may not seem like a lot of electricity but if you add up how many people have cellphones then the power usage is quite alot. If all cellphones had solar panels on the back, front, keys and around the screen then all you would have to do is leave your phone by a sunny window to charge it. Only on rainy days would we have to…Continue

My solutions is Building drainage system auxiliary power supply.
I live in the city often rains. Through construction of drainage system, the potential energy rainwater from high to low into electricity, you can reduce household power consumption.

I live in Nuremberg, a very hilly city. I could combine my bike with a generator which could be hooked up with my mobile phone. Once I ride downhills, electricity can be generated and my mobile phone will be charged easily, maybe not fully charged at once, but considering that I ride bike at least twice a day, the power will be sufficient for a daily use.

I think putting solar panels on household appliances could save a fair amount.

Everyday I use lights in my room to read at night. Another way I could power these lights could be to use solar panels. I could connect the solar panels straight to my room and use the energy to power my lights as well as my clock. Also it could be used to charge electronic items such as cameras and cell phones.

Many towns and cities are saving money on their power bills by changing from incandescent light bulbs to light-emitting diode (LED) lights. These lights can be used in traffic signals, crosswalk signs, and even holiday displays.
LED lights have an extremely long life span and use much less energy than incandescent bulbs. Switching to LED lighting can save 40 to 70 percent of the electricity a city uses for certain lights in parking garages, parking lots, outdoor parks, and on…Continue

Maybe a solar-powered laptop? Or water-turbines in gutters that generate electicity? A moat with a giaant water-turbines to crate even more electricity? Maybe a jacket or backpack with a special speedometer thats generates energy when you run, bike or jog? All good ideas that could be put into action.

I think you could use a way of absorbing light from outside and try and project it through the lights in your house it would save power there are always solar panels and charge torches for saving power and mini wind turbines.
