June 21, 2013 » Bicycle Music Festival Tomorrow, June 22nd, the 7th annual Bicycle Music Festival takes San Francisco by bike. It begins at noon in Golden Gate Park, then bikes will haul a live music stage through the city to arrive in the Mission District at 6 p.m. Entertainment--all free--will continue until 9 p.m. For pedal-power enthusiasts, this is a chance to see (and maybe participate in) a bike-powered concert. This year's festival features a 14,000-watt PA system, the largest ever for the event. It's part of Rock the Bike's pedal-powered stage, in which humans power not only the amplifier, but also the lights, sound board, and more. According to the Bicycle Music Festival schedule, fifteen musical acts--plus activist Bill McKibben--will take the stage throughout the day.

By: tamaraMay 15, 2013 » Fully Human-Powered (Concept) Home Artists at the Spanish firm Elli have designed a truly human-powered home. This small abode with translucent walls would challenge residents to use their muscles to operate its appliances, lights, and greenhouse hoses. According to an article in co.EXIST, "The JF-Kit House [named after Jane Fonda]... is an experiment in 'domestic fitness,' rendering 'the image of a possible future where citizens produce part of their domestic energy requirements with their own physical activities.' Each room features a fancifully named exercise station that would, theoretically, help create energy to power the home, including an 'arm workout bureau,' a 'spinning kitchen,' and a 'triceps greenhouse.'" JK Kit Home interior The JF-Kit House has been installed on a Brussels roof as a prototype. Less practical than artistic, it's a designer's challenge to reconsider domestic habits and what role our bodies and muscles can play in maintaining sustainable living spaces. More photos here and more background info here.

Payton Kaar and Kiona Elliott, two young women from Northeast High School in Broward County, Florida, brought their pedal-powered water filtration system. They convinced the president to pedal for a few minutes, as shown here (he hops on the bike around 6 min., 30 sec.) and provided a great explanation of how the filtration system worked. Obama pronounced the invention "Outstanding." Congratulations Payton and Kiona!

Watch the video for a great overview of several human-powered devices, including a bike blender, water pump, grain mill, electricity generator, and a very ingenious straw chopper. (See also The Human-Powered Home for plans on building your own human-powered blender, mill, generator, and pump.) Corson-Finnerty apprenticed with Maya Pedal and now works for Aprovecho in Oregon. He also posts notes from his various home experiments on his blog. Thanks, Matthew, for continuing to innovate and explain pedal-powered machines!

By: tamaraApril 14, 2013 » Bike Blenders and Chocolate Readers of The Human-Powered Home are probably familiar with pedal-powered blenders. This weekend I spoke about human power at an area alternative energy and green home show, and my friend Lynn was kind enough to join me and demonstrate her bike blender (a Rock the Bike model). Lynn studied with Michael Sacco at ChocoSol as part of establishing her own human-powered, socially-conscious artisan chocolate business. (She and I will be rigging up a pedal-powered cacao cracker in the coming months.) Here she is making kale and blueberry smoothies -- sadly, chocolate wasn't available -- for the crowd to show how the bike blender works. Thanks to Wendy for helping out! GM_demo_2GM_demo_1

By: tamaraApril 14, 2013 » Human Power Harnessed During Paris Marathon The human power of thousands was harnessed at the April 7th Schneider Electric Paris Marathon. Tiles made by Pavegen placed along certain portions of the route converted runners' and spectators' footfalls to electricity. According to this article in Energy Harvesting Journal, "The Pavegen tiles flex 5mm when stepped on, converting up to 8 watts of kinetic energy over the duration of the footstep, i.e. 8 joules." The total amount of electricity generated during the race has not been revealed yet.

By: tamaraJune 7, 2012 » Walking Power The Human-Powered Home describes the heel-strike generator, which was developed with funding from the U.S. Department of Defense as a way of harvesting energy from walking. Since the book was published, examples of collecting power from walking or running have multiplied. Most recently, Kenyan entrepreneur Anthony Mutua, unveiled an ultrathin chip that can be inserted into any shoe and used to charge a cell phone, either on the go or after a run or walk. Meanwhile, the military continues to pursue ways for soldiers to charge small electronics on the go. A recent example is SPaRK (Soldier Power Regeneration Kit) from SpringActive, Inc., which the manufacture claims can generate 3-6 watts of (continuous) power per leg while walking at 3 mph.

Environmental advocacy group Times Up! helped set up the generators. According to one article, it would take 11 pedal-powered electrical generators to meet the New York group's needs. Meanwhile, protesters in San Francisco are also generating their own electricity with help from Rock the Bike. Check out more articles on the use of human power in the Occupy movement here and here, with videos here and here.

By: tamaraApril 11, 2011 » Wearable Generators Thanks to a fan for pointing me to this article about researchers at the University of Auckland who are experimenting with dielectric elastomers to make wearable generators. From the article: "In a paper in Applied Physics Letters this week, the Auckland researchers described building a 110-millimetre-wide, plunger-shaped generator capable of producing 10 milliwatts of power." Dielectric elastomers can be used in generators because the material induces a slight current differential each time it's compressed. The Auckland scientists' approach is similar to what the U.S. military pursued in its now-abandoned energy harvesting boot (as described in The Human-Powered Home), but they're aiming for something more flexible, lightweight, inexpensive, and probably better suited to the consumer market.

Using piezoelectric crystals to generate electricity from human movement isn't a novel idea. Its varied applications are described in Chapter 1 of The Human-Powered Home. But now scientists at Princeton have printed the crystals onto a flexible rubberlike material that's also biocompatible, so it can be implanted in the body. As you move, the material could generate enough electricity to run a medical sensor. Outside of the body--for example, embedded in clothing--a flexible generator could charge your cell phone or portable music player.
