Underwater city:

A Japan company will create a city underwater.

1/What is this technology/invention?

This invention is an underwater city. This city will be “normal” with shopping center, hospital, home … And on the bottom of the city it will be create a research center.

2/How does it work?

This city creates her energy by different ocean temperature and micro-organisms for create gases to heat the city.

3/What will it bring to earth?

It will bring to earth a green city and space who people can live protect over tsunami and sea rising level.

4/Is there only a benefit?

It’s a space benefit and protect people benefit again tsunami.

This city use :

-no space who we can create field

-Green energy
The problem is the next: How the the man can live under water without sun lignt?

- What is this technology/invention ?

This technology is a revolution for the car. It uses two or many energies for the car to be used longer.

- How does it work ?
This technology helpes the Earth because it use two energie for make one. This technology uses electric and petroled and gasoline . All that it's hybrid.

- What will it bring to earth ?

For the earth, this technology is good because, there is ressources shortage and the price of gases increased. To conclud this technology is very good for the planet.

- Is there only benefit ? Explain the pros and cons.

Pros :
- It uses less natural gases.
- It's less expensive
- It pollutes less

Cons :
- The car rolled slower

1-biofuel it's a conversion biomass to liquid fuel.
NREL exploit this technical.

2-machine transform biomass to biofuels by fermentation

3-this fuel bring less pollution and new fuel organic and the techical creat a new jobs.

4-no because corn used for biofuel doesn't used for feed poor population,the price of biofuel is most expensive but it's benefit because there are less pollution,this technical use organic waste.

1) this type of technology is to put some crops on the  walls or the roof of building or even make building especially for crops !

2) This, is working with condensation wich the crops are making with the soil on a special membrane, so they can 'make' there own water and filter rain's water for people who are living in the building.

3) It will bring to earth place because now in the USA the place of the crops is like the state of Virginia, and with vertical farming we will win place !
And it will be less polution caused by the transport of that crops because they will be in the town and near the people.

4) No there isn't only benefit because that type of structure cost a lot and not everybody can pay for this.
The pros are the place in a world wich is always growing up (+ 3 billion in 2050) and less polution caused by the transport.
The cons are the price and the time that will be take to build that type of structure and not every town or country can or would like to pay that .

Alexis S.

1) What is this technology/invention ?

This technology is wind turbines.
These are tall pylons with long blades (15 meters x3)

2) How does it work ?

This technology uses the wind to be actioned and produce energy.
The long blades are actioned by the wind (when the wind is present).

3) What will it bring to earth ?

It's a green energy, it doesn't pollute.
It produces energy without greenhouses gases.
The lifespan of the product is between 20 and 30 years.

4) Cons :
- Takes place
- Dangerous for something which is fly (blades)
--> For bird
- It wastes the landscape
- It's noisy

Pros :
- A wind turbine is recyclable
- Doesn't pollute with greenhouses gases or rubbish
- Farm activities can continue around a wind farm

What is this technology/invention ?
- It consists in collecting the solar energy to create electricity. Peoples mostly use the produced electricity to heat their homes they also use it to use electric devices .

How does it work ?
- It works with solar photovoltaic systems that convert sunlight heat into electricity.

What will it bring to earth ?
- First, it is more ecological because sunlight is a sustainable energy
- Secondly it reduces the consumption of fossil fuels like the petrol . It is better because the petrol is not a susainable energy and petrol produces greenhouse gases and air or water pollution.

Is there only a benefit ? Explain the pros and cons ?
- For the reasons we wrote above using the solar energy almost only have benefits, the only problem is that the photovoltaic systems are very expensive but in the long-term they are profitable.

-This invention is a genetic innovation :
*muscle-bound cyborgs,
*becoming electronic immortals,
*new human species.

- It work :
* in small and isolated populations,
*with a mutation,
*Is passed down through generations,
*Parents could basically choose which sperm and egg get to meet up to produce a baby based on genetic information about which genes contribute to which physical and mental traits

-it will bring succeed economically and in raising kids to earth, higher earnings, social status, and sexual attractiveness.
In the far distant future, habitable planets beyond our solar system were colonized by Earth migrants

- Cons :
*The human population will become more alike as races merge, he said, but "Darwin's machine has lost its power.
* he earth will be unihabited

-pros :
* 99 percent of british's children survived to 21 today
*  humans taking charge of their evolution and transcending their biological limitations via technology.

-This invention is to grow plants and seeds into space (in the International Space Station). The scientist plan on growing food in orbit to have sustainable food for a manned mission on Mars.
-The astronaut have grown plants like lettuce and a flower, and they want to grow tomatoes too.
-That could help earth in a perspective of a manned mission on Mars to have enough food to live there.
-The pros:
The crops "brighten up" the space station, it's nice looking. It could also be a solution for food shortage.
-The cons:
Into the space, the temperatures are really hot and there is many radiation so it's difficult to grow plants. But the ISS is in low orbit so the  Earth’s magnetic field protect a bit the plants.

-What is this invention?
-How does it work ?
-What will it bring to earth?
-Is there only a benefit ? Explain the pros and cons.

Products on the market are made from a variety of natural feedstocks including corn, potatoes, rice, tapioca, palm fiber, wood cellulose, wheat fiber and bagasse. Products are available for a wide range of applications such as cups, bottles, cutlery, plates, bags, bedding, furnishings, carpets, film, textiles and packaging materials. Bioplastics are plastics in which all carbon is derived from renewable feedstocks.
It will be better for earth because petro-plastic polluted but bioplastics is biodegradable
Pros : Less petro-plastic, biodegradable plastics, it can be made from a variety of renewable resources, it can be composted, it can contribute to healthier rural economies, ...
Cons : it costs money, we have to choose between feeding the population or making bioplastics

-What is this technology/invention ?
It is the direct human manipulation of an organism's DNA in a laboratory environment

-How does it work ?
The scientists change the DNA of food to create and producte more new generation of crops

-What will it bring to earth ?
The GMOs will bring a lot of food so resistant and stronger for no more food shortage.

- Is there only a benefit ? Explain the pros and cons.

The pros are :
- The food is more resistant and stronger with GMOs in DNA
- They stoped the world hunger

The cons are :
-GMOs created  illness on the animal studies
-GMO crops cause increasing use of pesticides and it's bad for environment
- Because of GMOs we are chimicals food to your dinner table
- Our bodies are absorbing but not digesting genecatly modifited DNA

1- Hydropower is a technologie who use moving water to produce mechanical or electrical energies. The first was creat in 1882. And it can help to control flood, to help supply and cities irrigation.

2- The water enter in a dam and is accumulate in a resevoirs and after go in a turbin to spin a generator to produce electricity. The force of courrent applies pressure on a turbine.

3- This technologie can control flood of many rivers. And produce less pollution. It produce clean electricity. With not more dam we can creat a lot of electricity in order to approvision a lot of people.

4-But this technologie at a lot of pros to becaus it has an negativ impact on the wild, more particularely for animals and plants who live around the river.
And it can change natural water temperature, water chemy, river flow characteristic and silt loads.
And the dam can cover important natural areas, agriculture land and archéological sites.
