I like jessica's idea. There would be so much energy made we wouldn't know what to do with it.Kids would become less lazy and more active with this idea.

I really love Jessica's idea because a lot of people play soccer. I magine how much energy one would produce in one game. And this idea is a good way to get kids off their behind and make a better world.

Jessica Lin's invention is AWSOME!!!!!!!!!!!!!!!!!!!!!!!!!!! She invented a soccerball that produces energy while used. This is such a great invention because tons and tons of people play soccer and tons and tons of people use electricity. With that we will be able to make energy without polluting the planet. Her inventing is great.

I am really astonished by what Fabio Rosa has done. According to TheNewHeroes, he brought hundreds of families electric powered pumps, refrigerators and lights for the first time in their lives. Rosa spread his idea to thousands of families, and eventually to more than half a million Brazilians. But in the late 1990s, the electricity industry in Brazil was privatized and the new owners weren't interested in pursuing his model because the profit margins in the countryside were too low. So Rosa came up with a new plan to rent solar power equipment to villagers who live in the most remote areas of Brazil. He is just one person and yet he has saved so many from suffrage.

I'm impressed by Jessica's invention because she makes electricity by playing with a soccer ball! Imagine how many people it can help!

Jessica Lin's invention really connected to me. Soccer is one of my favorite sports and to create electricity when you kick it is out of this world. The invention is called "sOccet" and it is a portable energy generator that generates up to 3 hours of power for every 15 minutes of play. It was invented by Jessica Lin's and 3 other ladies from Harvard. They inspired many people including me.

I was so inspired by Jessica Lin's invention that I have to write this about her. She created a soccer ball that produces energy when being used for play.This invention was the "sOccet" and it can generate enough energy from 15 minutes of play to power a LED lamp for 3 hours. If her and her invention aren't amazing and innovative, I don't know what is.

I could discover some interest energy projects, which partially in use. For example, the use of energy-producing tiles. The idea is, that everytime when somebody walks on this slab, it produce energy. By every step the kinetic energy changed in electricity by a dynamo. This slabs could be used in a disco as a dancefloor or in a shopping street. These slabs are called Pavegen-slabs and should used between the Westfield City Shopping Center and the olympic stadion for the Olympics 2012 in London. This could be also used for streets or highways where million of cars drives every day.
An advanced idea is the Energy-Harvesting-Method. With this method should energy produced by movements, pressure and temperature. For Example energy should be produced while somebody train in the fitness center on a bike. While using the bike, energy will be produced by a dynamo or a sensor. A sensor can also produce energy when people using a lift or when a train pass the station. By that way, nearly every electric device could produce energy.

Both ideas can used easily and there is no restriction. I think the problem is that it is to expensive to install such ideas in a big style at the moment. Therefore, it is still not used much.

First of all I have to say that I am very impressed by the ideas of Jessica and Hugo which are mentioned above. They use evidently 'easy' ways and equipment to improve the energy supply of those who are not connected to the power supply system. Furthermore they made sure to use only affordable and regional specificities to implement their ideas and conceptions.
Noodled over that 'stories' I had a look to suggestions for generating energy which are forward-looking around me here in Germany. So I came across with the topic biogas. Therefore for example degradable bioma**** such as kitchen waste, starch and sugar industry waste, as well as lopping or plant residues are needed as important basics for this process. Another procedure is to use methane which is produced by cows in great quantities. Methane is an important greenhouse gas that, per molecule, contributes about 25 times more to climate change than carbon dioxide. On this account it is important to focus more strongly on agriculture and livestock breeding to use further opportunities offered by this subject. Around 7 percent of CO2 emissions consist of this sector.
To put it simply it is possible for farmers to convert cow dung with the help of a digestion tank into electricity. It could be said that cows are 'little power plants'. Especially their excretions (dung and manure) are the basics for renewable energy. Only one animal produces 8,3 kilowatt hours per day (based on 5 kilo manure and 80 litres dung). This is equivalent to the needs of an average household.

The energy potential of one cow is higher than the standard power consumption even if all devices are switched on.

This approach is already used in Germany and also in other countries. The number of biogas plants is increasing constantly. So I tried to find out more about recent approaches to generate energy. A further possibility for generating energy is to use grass as raw material. Here the project 'PROGRASS' set a good example for extracting the energy of biomass. The University of Kassel developed this technological and process orientated approach to produce bio-energy (electricity and solid fuel) also from mature grassland. The general idea is similar: With the help of a portable plant the grass is processed to biogas. This is the basic to develop heat and electricity in a thermal power station.
These are conceivable alternatives for electricity generated by nuclear power which is frequently discussed because of current events (e.g. F**ushima).

But I also wanted to present you another possibility to generate electricity, in a very specific sector. I live in Brunswick, so automotive industry is an important business for this area in Lower Saxony. In that sense I encountered that it is possible to generate electricity out of the exhaust gases of a car. As a consequence cars could consume less fuel and would have fewer emission of carbon dioxide. A thermoelectric generator uses voltage between two electric conductors with different temperatures. The electricity generated in that way could be used for radio or lighting in the interior space.
The German Aerospace Center (DLR) presented a prototype. The thermoelectric generator was tested successfully in a pretest vehicle.

I total agree with Yannis! But in my opinion it is also necessary that we develop solutions for radioactive waste and I guess if we just switch off the Nuclear power plants nobody will take care of this waste... There are technical possibilities to reduce the radioactivity of radioactive nuclear waste significant, but it is not used in the way it could... the Energy Industry prefer to enlarges their profit.
I think there are two opinions:
First the government force the Energy Industry to find a solution
and second the government presents that it is worth to work on this solution.
And as you can imagine, to force somebody is never a good alternative.
There should be a program with supports those companies which work on this solution.

In the future if we don't do something, we will run out of fossil fuels and it will cause a lot of pollution to the environment. We can start switching to renewable sources of energy like solor or wind energy. This will mean a better future for all of us.

In Denmark we save a lot of energy on biking. Especially in Copenhagen a lot of companies have made biking and bikes trendy! wich makes everyone want to bike.
I dont want to talk about one specific firm but I will link this video for you to show you want I mean; http://www.youtube.com/watch?v=xsDxOx7PUP0&feature=player_embedded

After one hundred years, everything will change. Most important of all, the energy sources we use now like oil, coal, gas will be run out. The government of each country will start a war because of the decreasing amounts of energy sources.
Due to there being less energy sources, the prices will be more expensive. People don’t drive cars, they ride bicycles instead. Scientist will find out and create the new energy. They will make new transportations that don’t use oil.
Because we don’t have oil, we can’t take airplanes to another country. A tunnel that goes under the sea will help us solve this problem.
The energy sources that we can use forever and never run out is what we should find out now. To make sure the future will be better, we should save our earth now.

Energy is a huge part of our world, it would be extremely hard to live without it. Going green is a great way to conserve energy even by using 'green' light bulbs. My friends father who is a huge fan of the green movement is working on a way to get energy out of different fruits and vegetables. He is extremely creative and thats what we need in our society people with creativity to try new things. Creativity is key in our world.

ENERGY 06

Energy problems are getting worse now; for example, oil is going to run out. Although oil and gas can make energy, they cause lots of pollutions. Some countries will fight for oil; it starts wars and causes damages. The price of energy gets higher and higher. What can we do to solve these problems? Maybe we can create new energy sources. We can try to use less energy.
After one hundred years, what will the world be? I think people will solve these energy problems. We use energy sources which can be used again and again. The following are some examples: wind, water, waves, nuclear, bio-mass. The price of energy is lower than now. People will invent some transportation methods which won't cause pollution, and they will plant trees to protect the Earth.
I believe that people will solve these problems in the future and we will have a nice world.

Arla is a big swedish dairy-company, and when they convert milk into milkpowder there is required large amounts of energy in the form of hot air. By recycling the hot air that is left over from the process, Arla milk in Visby on Gotland saves 500 tons of CO2 a year..

A German owned company IMO has set-up a plant in USA that will make the largest solar tracker solar panels to tap solar energy. As per Ruediger Unverzagt and Klaus Pless, respectively the CEO and vice-president of this company, these solar tracker solar panels are the largest in Summerville in South California. IMO is looking forward to commercially sell these solar tracker solar panels. Despite being huge in size, they are very easy to assemble and one can assemble them just outside the building where they are to be installed.

I chose Gyanesh Pandey as someone who is inventing creative, sustainable ways to power our everyday lives. He is from the poorest state in India, where eighty five percent of people do not have access to electricity. Although, he grew up very underprivileged and in an unsafe environment, he found a way to save enough money to get to California and studied electrical engineering. Being in the United States, he quickly realized how much energy is wasted everyday and wanted to find a solution for that, along with a way to give power back to his homeland. He invented and established the Husk Power System, creating energy from rice husks, which are normally thrown into land fills. Already 60 rice husk power plants are up and running, serving 60 villages and 150,000 people. In ten years the company hopes to be in ten to fifteen countries, serving 10-20 million people.
