Energy #Startup:This Paris Floating Gym Which Will Turn Your Sweat Into Electricity (en/fr)

English: Italian firm Carlo Ratti Associati came up with a brilliant way to inspire people to exercise more. They designed a boat that uses human energy to sail down the Seine River in Paris.

This futuristic project tends to innovate the way of traditional fitness while trying to loose your extra kilos.Each of this floating gym machines is attached to a black box with wires running out of it. The box is a compact generator that converts the motion of the wheels into electricity, which is then fed into the power grid, offsetting some of the club’s energy use. For these gym-goers, it’s not just about their cardio fitness; their sweat is helping to make the planet a bit greener.The box is a compact generator that converts the motion of the wheels into electricity, which is then fed into the power grid, offsetting some of the club’s energy use.

By adopting power-producing exercise machines in this way, gyms can promote themselves as environmentally friendly and also reduce their electric bills. This concept has started in the United States but “la Seine” is a more beautiful place to work out. At least three start-ups in the United States are now selling equipment to retrofit aerobic machines—stationary bicycles, elliptical trainers, and steppers—into electricity-generating gear. These companies have already converted several hundred machines at dozens of U.S. health clubs and university gyms.

In Paris, the boat is 65-feet-long (20-meter long) and holds up to 45 people. “The Paris Navigating Gym investigates the potential of harnessing human power,” Carlo Ratti said. “It’s fascinating to see how the energy generated by a workout at the gym can actually help to propel a boat. It provides one with a tangible experience of what lies behind the often abstract notion of ‘electric power’.” It’s still in development, but the designers estimate that it could be completed in 18 months.

The Paris Navigating Gym works by converting the pedal power into utility grade electricity. However, if there won’t be enough passengers on-board to run the ship, it will be able to use renewable energy sources, like the photovoltaic cells on its roof.

The Navigating Gym will allow Parisians to inhabit the river all year long. The augmented-reality screens installed on the boat will show guests both the quantity of energy sourced from the workout, and data about the Seine’s environmental conditions, tracked in real time by sensors incorporated on the vessel. Encased within a transparent glass covering, open in the summer, the gym allows an extraordinary view of the urban panorama. And at night, the boat can even be used for parties and celebrations.

One more reason to visit once again or for the first time Paris!

Français:Cette salle de sport flottante pourrait naviguer grâce à l’énergie des sportifs

Si vous aimez flâner à Paris en faisant du sport, ce concept est parfaitement idéalise  pour vous. “Le Paris Navigating Gym” pourrait bien naviguer le long de la Seine en utilisant juste la sueur de votre front. Un concept inédit mêlant activité physique et écologie. Ça change des traditionnelles « salles de muscu ».

C’est  le cabinet de design italien Carlo Ratti Associati qui a imaginé une salle de sports à donner envie, même au pire flemmard des sportifs, de se dépenser à fond en regardant la Seine. Plus besoin de prendre un bateau mouche pour faire le tour de la capitale française. Surtout si vous   Équipée de grandes baies vitrées avec vue imprenable sur Paris, cette salle flottante de 20 mètres de long, baptisée «Paris Navigating Gym», pourra accueillir jusqu’à 45 cyclistes. En s’activant pour perdre des calories, les sportifs produiront l’énergie nécessaire pour faire avancer le navire sur la Seine et prendre des passagers sur les rives de la capitale.

Car cette salle flottante serait, en partie, propulsée par l’énergie que fourniront les sportifs en se défoulant sur les vélos installés sur la plate-forme. “Il est fascinant de voir comment l’énergie générée par une séance d’entraînement à la salle de gym peut effectivement aider à propulser un bateau. Il fournit à l’individu une expérience tangible de ce qui se cache derrière la notion souvent abstraite de puissance électrique”, explique Carlo Ratti sur le site Designboom .

En cas de manque d’affluence dans la salle ou bien de coups de pédale un peu trop mous, des panneaux solaires offriront la source d’énergie complémentaire. Ce projet a été développé en partenariat avec Technogym, qui commercialise des équipements sportifs nouvelle génération permettant déjà de récupérer l’énergie produite, et Terreform One, une organisation qui a déjà proposé un premier projet de gymnase flottant en 2008.

Inspirée des mythiques bateaux-mouches, la salle de sport flottante intégrera à ses grandes baies vitrées, des écrans indiquant la quantité d’énergie produite au cours de la séance, des données en temps réel sur la Seine ou encore des informations constantes sur le bateau. Le bateau est prévu pour mesurer 20m de long et accueillir 45 personnes. De quoi envoyer du nœud et profiter à fond de l’expérience.

In Oman bacteria-induced biofuel is getting patented


Muscat,Oman Sultanate: Mohab bin Ali Al-Hinai, assistant professor in the biology department of Sultan Qaboos University (SQU), has obtained a patent for his research on bacteria that contributes to the production of biofuels.

Al-Hinai said the idea of producing biofuels by bacteria was a development of ‘acetobutylicum clostridium’ bacteria which is the fastest in its group in the production of organic materials usable as biofuels, according to Oman News Agency.

He added that the significance of the said bacteria is that it produces biofuels from plants that contain fiber and not from components of staple foods for human consumption such as maize, wheat, and sugarcane.

He affirmed that the most significant challenges are to find a way to make this invention economically feasible. He added that he is currently working on the development of research on biofuels from agricultural waste and the smallest organisms found in the Omani environment.

  • Why Bacteria-based biofuels?

By tweaking the smallest units of life, scientists are making bigger gains in producing alternative and renewable energy, with recent efforts aimed at molecule-level controls and promoting fractal growth patterns to create different fuels and improve efficiencies.

Bacteria, which range from 0.5 to 5 microns in size, perform functions that can be exploited, enhanced and modified to produce fuels. As they move, breathe, eat and reproduce, bacteria produce byproducts like ethanol and hydrogen while feeding on simple sugars, starches and sunlight. The cells themselves can also be harvested for biodiesel precursors.

The organisms may be used to produce fuels directly from biomass, including cellulosic biomass.  When all of the steps of digestion and fermentation are combined, it is called consolidated bioprocessing.  The organisms available for consolidated bioprocessing to produce cellulosic ethanol do not produce high concentrations of the ethanol, and therefore it isn’t cost effective to use them according to Biofuels Digest.

Even, back now in 2012, researchers genetically modified E. coli bacteria to convert sugar into an oil that is almost identical to conventional diesel.

While petrol and diesel release carbon dioxide that has been stored deep within the Earth, biofuels are said to be carbon neutral because they release as much CO2 into the atmosphere as the plants they are made from absorbed.

However, the energy it takes to grow and process the crops needed for biofuels also should be taken into account, as this adds to their “carbon footprint”.

A report by Chatham House said biofuels were expensive and worse for the climate than fossil fuels.
