Siegeszug des „Pedelecs“ : Das E-Bike hängt die Elektroautos ab - Technologie - Energie + Umwelt - Energie + Technik - Handelsblatt.com LÖHNE. Tobias Höhe öffnet das Tor seiner Doppelgarage, wirft einen Blick auf den grauen Golf, klettert dann aber auf ein aluminiumfarbenes Zweirad. In den kommenden 40 Minuten wird es ihn quer über die Schwäbische Alb tragen, 16 Kilometer vom Wohnort Westerstetten bis zur Sparkasse Ulm, Höhes Arbeitsplatz. Doch einen verschwitzten Kragen hat der 31-jährige Banker nicht zu fürchten. Höhe ist nur einer von 150 000 Deutschen, die im vergangenen Jahr umgestiegen sind aufs "Pedelec", wie Experten den High-Tech-Drahtesel getauft haben. 2010, glaubt Siegfried Neuberger vom Zweirad-Industrieverband ZIV, könnten 180 000 weitere hinzukommen. Entscheidern in Wirtschaft und Politik dürften die Verkaufserfolge zu denken geben. Doch handfeste Ergebnisse der Forschungsinitiative, an der Großkonzerne wie BASF, Bosch, Evonik oder VW tüfteln, gibt es bislang kaum.

Elements & Periodic Table: Metals We wanted to give you a big overview of metals before we get into details about specific families. Almost 75% of all elements are classified as metals. They are not all like silver (Ag), gold (Au), or platinum (Pt). Those are the very cool and shiny ones. What are the characteristics of metals? 1. 2. 3. 4.

A Conversation With Fred Kent, Leader in Revitalizing City Spaces - Samantha Michaels - Life For someone who makes a living revitalizing city spaces, Fred Kent has an interesting take on professional urban designers: he thinks they're overrated. The real urban design experts, he says, are the ordinary people who actually live and work within a community. And with his nonprofit organization, Project for Public Spaces (PPS), Kent is doing his best to empower them. Founded in 1975, Project for Public Spaces helps community members design, plan, and manage public spaces by considering their own needs and values. What do you say when people ask you, "What do you do?" We use a different approach to designing and planning cities -- not a top-down approach, but a community-led approach that focuses on places. In over 35 years we have worked with 3,000 communities in 42 countries, allowing people to define and create places that become the soul of their neighborhoods, cities, towns, regions, and even their countries. We call what we do 'Placemaking.' The obsolete are everywhere, though.

Data Visualization: Modern Approaches - Smashing Magazine Data presentation can be beautiful, elegant and descriptive. There is a variety of conventional ways to visualize data – tables, histograms, pie charts and bar graphs are being used every day, in every project and on every possible occasion. However, to convey a message to your readers effectively, sometimes you need more than just a simple pie chart of your results. In fact, there are much better, profound, creative and absolutely fascinating ways to visualize data. Many of them might become ubiquitous in the next few years. So what can we expect? Let’s take a look at the most interesting modern approaches to data visualization as well as related articles, resources and tools. 1.

Technologies méconnues pour la vie en autarcie Nombre de personnes souhaite avoir au cas où, de quoi s’en sortir un peu si quelque chose arrive, n’importe quoi: conflit majeur, grosse panne d’électricité, catastrophe naturelle, krach financier, n’importe quoi qui puisse changer notre manière de vivre de manière radicale, et en cette période d’instabilité sur la planète, toutes les options sont envisageables… Pour d’autres, le simple fait de vivre de manière plus simple et plus traditionnelle n’est pas une option, c’est devenu un but. Pourtant, qui dit sortir de ce système (volontairement ou non) dit rencontrer des difficultés, et de ce côté, chaque piste est intéressante et mérite d’être explorée. C’est pour cela que je vous relaie cette liste, peut-être certaines idées vous paraîtront intéressantes et exploitables, et peut-être même trouverez-vous des solutions auxquelles vous n’avez jamais pensé!

Architecture Meets Fashion: The World's Best Flagship Stores - OpenBuildings - Life The two art forms have a shared understanding of space, structure, and composition, giving them a lot of common creative ground Fashion and architecture have experienced an unrivaled period of growth, with star architects and major fashion brands working closely to build architectural wonders around the world. But is this simply a classic commercial act or a romantic matter based on a natural affinity from both sides? Clearly, architecture is one of the most powerful tools for achieving corporate identity in the fashion world and, on the flipside, these buildings are the perfect catwalk for promoting architectural creativity at its most extreme. This collection of buildings shows how fashion and architecture are in fact capable of enhancing each other's relevance in the world we inhabit; Architecture and fashion's shared understanding of space, structure, and composition mean the two art forms have a lot of common creative ground as a starting point for evolution.

50 Great Examples of Data Visualization Wrapping your brain around data online can be challenging, especially when dealing with huge volumes of information. And trying to find related content can also be difficult, depending on what data you’re looking for. But data visualizations can make all of that much easier, allowing you to see the concepts that you’re learning about in a more interesting, and often more useful manner. Below are 50 of the best data visualizations and tools for creating your own visualizations out there, covering everything from Digg activity to network connectivity to what’s currently happening on Twitter. Music, Movies and Other Media Narratives 2.0 visualizes music. Liveplasma is a music and movie visualization app that aims to help you discover other musicians or movies you might enjoy. Tuneglue is another music visualization service. MusicMap is similar to TuneGlue in its interface, but seems slightly more intuitive. Digg, Twitter, Delicious, and Flickr Internet Visualizations
Relativistic Baseball What would happen if you tried to hit a baseball pitched at 90% the speed of light? - Ellen McManis Let’s set aside the question of how we got the baseball moving that fast. We'll suppose it's a normal pitch, except in the instant the pitcher releases the ball, it magically accelerates to 0.9c. From that point onward, everything proceeds according to normal physics The answer turns out to be “a lot of things”, and they all happen very quickly, and it doesn’t end well for the batter (or the pitcher). The ball is going so fast that everything else is practically stationary. The ideas of aerodynamics don’t apply here. These gamma rays and debris expand outward in a bubble centered on the pitcher’s mound. The constant fusion at the front of the ball pushes back on it, slowing it down, as if the ball were a rocket flying tail-first while firing its engines. After about 70 nanoseconds the ball arrives at home plate. Suppose you’re watching from a hilltop outside the city.
Energies | Free Full-Text | The Global Surge in Energy Innovation | HTML 1. Introduction The global energy system provides, through a complex web of processes and interactions, the foundation for almost all modern human activities. The energy sector is substantial, having made up almost 4% of total economic activity for reporting OECD (Organisation for Economic Co-operation and Development) countries in 2009 . Over the past decade, the situation has been changing. This paper examines the major factors associated with the revitalization of energy innovation, the changing distribution of energy R&D resources and the underlying scientific developments which are providing transformative energy opportunities. Innovation systems theory provides the framework for the paper. To examine trends in both public and private expenditure on energy RD&D, we utilise datasets compiled by international organisations such as the OECD, IEA and World Bank. This paper is structured as follows. 2. Figure 1. Figure 2. Figure 3. Figure 4. 3. 4. Figure 5. 5. 5.1. Figure 6. 5.2. (a)
