The search of a sustainable way of transport, which provides independence from hydrocarbon and respects the environment, leads us to the road of electric vehicles. This new car model makes use of electricity as the new source of energy, in order to achieve a reduction of the CO2 emissions and looking for the participation of renewable energies in the process. However, the cost of the project is one of the facts that can make us think about the convenience of this solution. A very thorough analysis is required, taking into account all the possibilities- price of recharge, batteries, government subsidies, autonomy⋯ This article tries to show the most relevant facts concerning the electric car so that the reader is able to make a critical review of the model.

The site in the north of Madrid that for many years was home to Real Madrid's training complex, is now occupied by the "Cuatro Torres Business Area". Four tower blocks have already been erected on the site and work is currently underway on the Madrid International Conference Centre, that will complete the complex. This group of buildings will change the skyline of the north of Madrid and are established in one of the city's most representative and symbolic areas. Torre Espacio, the building promoted by the Villar Mir Group, is the tower furthest to the north. The tower will be the headquarters of Inmobilaria Espacio and other group companies, including OHL. This article outlines the most important characteristics of the building, though placing particular emphasis on structural aspects, both In terms of design and construction.

Very little has changed with respect to water matters over the last forty years. The same roles have been taken over by different individuals. There has been no change. The call for solidarity between regions for the distribution of water goes against the proclamation of the European Water Charter that "Water knows no boundaries". In Spain the failure of water proposals is largely down to the concessions granted by central government to the regional authorities, and invoking the precept of solidarity in vain. This failure in Spain is all the more incongruous as this is an area when the full value of water has been well understood for over 100 years.

Recent hydrological planning, far from achieving a fair and sustainable distribution of water resources, has left Castilla-La Mancha submitted to some other regions' purely economic interests. Moreover, the environmental demands required by The EU Water Frame Directive have been set aside..

By tracing international architecture from the mid-20th century (and possibly even further back to the early 1900s) we may appreciate the collaboration between architects and engineers (essentially structural engineers) in the design and construction of the most significant works of architecture. The contribution of engineering in the search for ever lighter roof structures, the modification of earlier structural solutions and architectural proposals for structures at the very boundaries of knowledge, as manifested not only by space frames and suspended roofs, but also by the structural transformation of tall buildings, reveals an architecture heavily influenced by engineering. From the end of the sixties and when attempting to transmit this influence as a technological image of architecture, including the external image of the building systems, the accesses to the buildings and the structural glazing solutions, architecture has required the support of engineering more than ever in the search for innovative solutions at the service of architecture. In more recent times, and now in the present century, geometrical mannerism has dominated the image of architecture and the ever-present support of engineering has been brought to the aid of architecture to produce sometimes contradictory results between structural rationality and the formal image of buildings.

In ancients times the roles of these two master builders - engineers and architects-were merged into one. Over the course of time, these roles took different paths until separating into the two specialized professions we know today and where both take their respective part in construction design. However, the lines between the two professions are becoming ever more blurred by the increasing need to meet public requirements, not only with respect to basic infrastructural needs, but also in terms of their iconic image.

Much has been written about the person of Leonardo Torres Quevedo, who was fundamentally an inventor and one of the most brilliant ever to have emerged from Spain, and undoubtedly the most prolific of all. For this reason, we shall not study his biography nor the host of inventions he made in many different areas, nor the multitude of other activities he conducted throughout his life. We shall, instead, concentrate solely on his work as an inventor and builder of aerial lifts, of which plenty has also been written; but here we shall focus on the gondola type lift, his most attractive element.

Estuaries are the protagonists of the Gulf of Cádiz, together with dunes and beaches. This is a low coastline, that is readily moulded by the action of the marine environment and one very vulnerable to the effects of waves, storms and climate change. The key to the management of the coastal physiographic units lies in an integral approach, made with sufficient foresight, of the complexity of its functioning and dynamics, based on scientific knowledge and the need to introduce integrated management techniques to recover its functionality and nature.

Concrete pavements have certain qualities (low maintenance and high durability, stable and resistant surfaces, light colour, mitigation of heat-island effect, aesthetic possibilities, etc.) which make their use in road surfaces highly interesting. This paper analyses those benefits along with certain drawbacks which have tended to be attributed to this solution (length of time up to opening to traffic, acoustic properties, etc.) which can however be suitably addressed using the techniques currently available. It reviews the various types of concrete pavement, aspects to be considered in their design (such as thicknesses or joints) and the available construction methods. A detailed analysis is made of certain options as regards the finish of concrete pavements in which colouring, printing, texturing, retarded curing and other techniques allow us to achieve a great variety of decorative effects without sacrificing slip resistance. Finally it examines some properties of lean-mix concrete road bases, as widely used in road pavements in many cities.

The workshop on style and form going under the title of "las buenas formas" that took place this Spring under the auspices of INTIC (ICT Integration) with the collaboration of the Madrid Residencia de Estudiantes sewed as an introduction to the artistic trends currently encountered in our professional environment and related spheres. The series of conferences and round tables provided first hand accounts not only by renowned engineers with artistic leanings, but also by other professionals from the worfd of Fine Arts who fully appreciate these styles and forms. This article comments on this particular subject and forwards the place for good form or aesthetic appreciation in engineering work, particularly when attempting to argue in favour of its own formal value and one, in this respect, different from that of the other constructive arts. This serves as the setting in which to present some of the findings of the workshop on "Las buenas formas" that took place between April and June this year. The workshop included interventions by Julio Martinez Calzón, José Serna, Carlos Castañón, Jorge Bernabeu, Miguel Aguiló and Fernando de Terán, all of whom being sufficiently renowned and esteemed professionals in this country to do away with any further presentation.
