Estamos preparados para enfrentar un TSUNAMI solar ?
Em notícia de Le Monde de 18 de abril 2012, cientistas demonstram preocupação com o ciclo de explosões, erupções e tempestades solares que estão re-iniciando. Após três anos de calmaria, a atividade solar parece estar recrudescendo, conforme ultimas observações.
Não é um fenômeno inédito, e tem ocorrido ciclicamente, mas somente recentemente, verificou-se que estas "tempestades" que lançam particulas magnéticas no espaço a milhares de kilometros por segundo, podem afetar sériamente nossos sistemas de comunicação, dos quais nos tornamos perigosamente dependentes.
Grandes tempestades solares já foram testemunhadas no passado, como em 1859, quando auroras "boreais" foram vistas no Caribe e na Venezuela. Como na época ainda não havia sistemas elétricos, os efeitos permaneceram apenas visuais.

O aproveitamento da energia solar tem futuro ?
Uma boa notícia a respeito das perspectivas de aproveitamento da energia solar no Brasil é seguida de uma má nos países europeus.
Nuvens negras ameaçam as industrias de painéis solares fotovoltaicos, uma vez que os governos decidem cortar os subsidios. Fábricas estão fechando da noite para o dia, deixando milhares de operários e funcionários desempregados. A crise é particularmente grave na Alemanha que estava, até agora, liderando em tecnologia solar.

SOLAR ENERGY: HARVESTING THE SUN (3)
AN ARCHITECTURAL APPROACH THROUGH LE CORBUSIER’S GROUNDINGS.
By Dominique Fretin
New building materials and methods, such as
concrete that was worshipped and broadly employed by modern architects, provided
independent structures that freed the façades allowing wide openings and much
more light entrance in the insides.
Concrete structures, walls and floors are also
suitable to store heat. When correctly sized and oriented they can provide
comfort during the winter days. Aware of those properties Le Corbusier also was
committed to technological advances and rather chose building systems and
materials that clearly proclaimed the expression of modern industry. Colors,
textures and shapes were bound to reflect the refinement, the lean sense of
efficiency avoiding all surpluses just like the industrial machine components.
Natural resources should be employed in a rational and organized way, through
technical proceedings.
Energy issues as regarded in our days are
seldom approached by Le Corbusier in his writings. He oppositely seems rather
enthusiastic about technical solutions he discovered during his travel in the United States of America in
the late 1920. In
his book “Quand les cathédrales étaient
blanches” (1937), he is bewildered by the successful actions achievable in
the “Pays des Watts ”[sic] and claims
that architecture should seize all new techniques available.
... No windows anywhere... silent
walls... Air conditioning is everywhere: pure, dustless and temperature is
constant. Am I in the 5th or 40th floor, secured within a
glazed aquarium?…[3]
… all modern technical devices must be incorporated to
architecture, but willing to transcend their simple utility. Such an
indispensable goal intends to offer the joys of the heart and of health to the
mechanical civilized men[4].
Although Le Corbusier’s concern were guided by
functionality, aesthetics, health and a certain “joie de vivre”, when it comes to sun reckoning, most of his
projects display the basis of passive solar techniques suitable for energy
efficiency. Shapes, structures, materials, openings and its eventual protection
seem to have been conceived with this particular purpose.
In the early Both postures, on the one side harnessing local natural resources and in the other side using the leading techniques and incorporating them in buildings, may appear self-contradictory. Nevertheless, they are present in all Le Corbusier’s buildings as he looked forward to transform architectural housing into “dwelling machines” by means of using simple and rational building solutions arranged with refinement of shapes, always interacting with environmental strengths.

AN ARCHITECTURAL APPROACH THROUGH LE CORBUSIER’S GROUNDINGS.
By Dominique Fretin
However, Le Corbusier’s ideas about how to
harvest sun’s light and heat and use it in architecture weren’t new. Most of
them were retrieved from traditional or vernacular building solutions, some
even from as far as the ancient Greeks time. Xenophon (ca. 430
- 354 BC), for instance, wrote in his Memorabilia (Book III, Chapter VII),
citing Socrates describing the advantages of solar orientation of an ideal
Greek house: “ Now in houses with a
southern exposure, the sun’s rays penetrate the porticos in winter, but in
summer, being less inclined, they afford shade. If, then, this is the best
arrangement, we should build the south side loftier to get the winter sun, and
the north side lower to keep out the cold winds. To put it shortly, the house I
which the owner can find a comfortable retreat at all seasons and can store his
belongings safely is presumably at once the most pleasant and the most
beautiful.” (apud Boyce, 1993). This very first registered concept of a
solar house was indeed a judicious one and has been followed by countless
architects and builders since then all over the western world (according to sunbeam
angles, i.e. local latitude), looking forward to more comfortable dwellings.
Nevertheless,
Le Corbusier’s merit certainly was to adapt such solutions to contemporary and
modern architectural expressions, as did many architects and builders through the
20th century. He first understood the benefits of sun rays on human health and
the advantages of natural lighting. He advocated the requirement of at least
two hour of direct sun beam inside new buildings as “medicine had proved that tuberculosis usually settles where the sun
doesn’t sink in …thus, a minimal
number of direct sun beam should be fixed for each home[1]..” (LE CORBUSIER, Athens
Chart, Item 26, 1933). He also learned to control heat and light, creating
wealthy spaces and energy efficient buildings as well as amazing atmospheres.
Notre Dame du Haut in Ronchamp (1954) gives an outstanding example of this last
assertion.
Search for light was an utmost precept to
modern architecture. “Licht” became the Bauhaus architects’ rallying cry ad was
heard far and wide. Most of Le Corbusier’s European designs clearly attest this
quest for lavish natural lighting, a conceivable attitude considering the
scarce luminance of some high latitude countries. It was not, at the time, an
energy saving issue but a genuine intent to bring more health, welfare, comfort
by aesthetic means as it can be well perceived in Vila Savoye at Poissy (1929 – Figure 2).

AN ARCHITECTURAL APPROACH THROUGH LE CORBUSIER’S GROUNDINGS.By Dominique Fretin
Paper presented at
URBENVIRON 2010
“Wouldn’t it be nice to die while swimming in the Sun?” is presumed to have asked once Le Corbusier alluding to his peaceful holidays at Cap Martin as he enjoyed the magnificent view over the Mediterranean sea from his summer hideaway: “Le Cabanon”. Whether this sentence is true or not, it underscores a certain premonition or betrays a staggering coincidence as the architect died on august 27, 1965, of a raging heart attack while he was lying on the beach after swimming, right in front of his cozy little shelter. Premonitions and chronicles aside, this thought also expresses brilliantly Le Corbusier’s concerns and penchant for Phoebus’ light and heat he knew so well to deal with in almost all his designs. In other words, he had mastered the sun and knew how to take advantage of its energy in architecture by achieving astounding solutions to lighten, heat or protect internal surroundings and arrange wisely, properly and magnificently, as he says, volumes and shapes under the sun light. (LE CORBUSIER, 1927) [1].

A morte do Sol
Daqui a 7,5 bilhões de anos o Sol vai se apagar. Mas, antes disso, vai crescer, brilhar muito mais e quase derreter o sistema solar.
