After printer, now 3D pen

09 Mar

After the printer, 3D pens It is the launch of WobbleWorks company, creatorEsculturas3D of the first mercado, 3D pen announced the launch of a children’s version of the portable printer called 3Doodler Start a portable printer, reference 3D printers.

The company ensures that it is completely safe, the pen now available for children is a version of the pen “adult” 3D 3Dooler launched in 2013 but had a successful release in 2015.

For this release the controls and operation have been simplified for use by children (actually the recommended minimum age is 8 years), to leave the plastic simply press the single button on the pen to start the output of plastic that is overheated internally.

The market that all copies did not wait long, since there are several alternative models, one is the Lix Pen, a pen developed by a team of designers and engineers with 14mm diameter, the object has the body made of aluminum and concentrates a weight 40 grams, and there are many other eastern origin.

The 3D printers followed the front of this market, their designs are more accurate, faster and generally were made by artists, but this new market that encourages individual creativity, particularly teenagers tend to grow.

The three weeks of COP 21

13 Nov

The three weeks of the opening of the Paris conference, already held the Pre-COP,PreCop21 attended by about 70 countries and chaired by Manuel Pulgar Vidal – Minister of Peru’s environment and president of COP20, the previous conference.
On the agenda were four central themes: the ambition of the agreement, its equity, the concrete actions to be taken before 2020 and the financing to be mobilized after 2020.
The French Minister of Foreign Affairs and International Development, Laurent Fabius, who is the president of cop21, showed the press the main objectives of this preparatory ministerial meeting.
Laurent Fabius said: “” We have had to the pre-COP an important step before Paris, but we are more than ever and mobilize the task that remains is considerable, “summed up in the press conference.
Brazil although the has a bold proposal for contribution in INDC (Intended Nationally Determined Contribution , the acronym in English), which would be 43% (the official website of the event registers 37%) involve illegal deforestation, reforesting 12 million hectares the recovery of 15 million degraded pastures and integration of 5 million hectares of crops, livestock and forests.
But we have in Brazil an extremely dirty matrix (hydroelectric being privatized and expensive nuclear power plants already tried to hang), and goals here are not serious, see the goals of economy and respect for labor achievements

 

As crises climáticas e o homem

11 Aug

O desconhecimento da própria natureza e da natureza que é exterior ao homemTerraCarbonívero é o que propicia a má relação com a técnica, que não é outra coisa senão a outra coisa que as formas de superação da própria natureza e de “dominação” da natureza exterior ao homem.

Primeiro porque a natureza exterior precede ao homem, enquanto a Terra tem bilhões de anos, a vida do homem no planeta data de aproximadamente apenas 350 milhões de anos, a vida primitiva começou antes no período entre 2.5 bilhões de anos e terminou há 554 milhões de anos chamado de Periodo Proterozoico, quando havia oxigênio e as primeiras formas de vida unicelulares, logo em seguida já ocorreu a primeira “crise climática”.

Pode parecer estranho chamar o período em que o oxigênio começa a existir ainda em níveis precários, e isto tornar-se “uma crise de poluição”, mas o oxigênio é um destruidor poderoso de compostos orgânicos, várias bactérias são destruídas por ele e isto obrigou uma “volução” pois os organismos vivos tiveram que desenvolver métodos bioquímicos para reter o oxigênio, um destes métodos foi a respiração aeróbica.

Os períodos entre que se seguem entre 542 milhões e 251 milhões de anos atrás, aproximadamente, são denominados: Neoproterozoico, Proterozoico, e Mesozoica., depois divivdem-se em períodos Cambriano, Ordoviciano, Siluriano, Devoniano, Carbonífero e Permiano, os dois últimos nos interessam.

O Carbonívero (Figura) ocorreu entre 360 a 286 milhões de anos durante o Paleozoicoo, foi o período de formação do ovo amniótico, que permitiu a formação do meio terrestre de determinados tetrápodes, que devido os 4 pés ou patas, permitiu a exploração do meio terrestre.

A segunda grande crise climática acontece no fim do período Permiano, entre 286 a 245 milhões de anos, foi o último período da era paleozoica, quando ocorreu uma grande extinção talvez a maior registrada na história da vida da Terra, dando origem do Triássico, a idade dos dinossauros.

A terceira crise climática foi a chamada era “glacial”, foi depois dela que nasceu o homem nos últimos 30 mil anos da história da Terra, o homem ainda é um bebe e a terra uma senhora.

 

Big networking that is not digital

28 Jul

You can imagine that there is nothing more complex than a computer network, orMaersk even the global network which controls stock and currency exchange rates, plus a plethora of products that go up and down in price every day, but that’s not true, and some would say that we can’t get to build bigger.

There are very complex networks that you have no idea around. One of them was shown on The Verge, which are ships carrying door-containers all over the world, in a global supply chain that transports from tablets to phones, food clothing, toys and souvenirs, etc. And is a country that does not produce any of this, just carries: Maersk of Denmark.

See in the picture (original BBC) a ship Maersk a mega-port in Korea, for this we need a big engineering solution, unprecedented a logistics problem truly create astronomical this network all over the world, delivering products from different sources, validity and natures and do all this work.

The company your in 125 countries, has 25,000 employees, 345 offices and more than 600 active ships, with more than 2 million containers moved per year, and she alone is responsible for 20% of the GDP of Denmark.

How technology helps Nepal

15 May

NepalThe technology was effective in initial help of the first earthquake in Nepal, but the second earthquake two weeks seems to be more cruel, as if the first killed more than 8000 people, the earthquake this time was in regions distances near the town Namche Baazar, which is close to Mount Everest, one of the highest in the world.

What is claimed now is the lack of more comprehensive high-quality maps, especially in remote areas, which means it is necessary to coordinate a series of medical efforts, food and shelter, in more complicated remote areas.

One of the efforts is the Kathmandu Living Labs, that uses many volunteers to create digital maps of the country, signaling the roads, hospitals and other facilities to the aid get faster, the advantage is that now there are these rescue forces in the country, they need access to this information.

You can find coverage of trabalos the KLL (acronym of Living Labs) in various organs of the international press The NY TimesBBC,Nepali TimesMy Republica, and Setopati  attesting to the validity of laboratory

The site explains that the emphasis of this laboratory is “in is on cutting-edge Web 2.0 and participatory technologies que empower and engage citizens in working with government and development”.

Company announces clean energy

07 May

The Tesla company had already announced last year the construction in the US state of Nevada a super lithium-ion Teslabattery capable of supplying power to several cities, the investment of 5 billion dollars (about 15 billion real) in partnership with Japanese Panasonic, now announces a new step in clean energy, Powerwall which is already being developed in a warehouse on the outskirts of Los Angeles, announced last week.

The Tesla Powerwall equipment is to supply home residences from solar panels, and can operate at night, in addition to providing a secure backup in case of a power outage, as news on Business Insider.

In theory the device can be mounted to a garage wall can make completely independent houses of traditional electricity, using only solar energy.

The idea of ​​solar energy can change the energy pattern around the globe, eliminating the anti-ecological (and often antissocial in Brazil) energy from hydroelectric and dangerous nuclear energy, and the announcement on first May, the company’s founder the American Elon Musk said the goal is to turn all worldwide energy infrastructure until we get the ‘zero-carbon’ sustainable, left to governments and energy companies will leave.

Later this year takes place in Paris the prestigious UNFCCC – or the United Nations Framework Convention on Climate Change that promises an effective and real pressure presence in governments and businesses.
