It is intended for engineers, software developers, and other technical people (like me!) who want to be more energy-independent and physically active when working from home. The design is based on what I have learned powering my home office using only human power for more than 10 years. Here's a brief video describing it (click the image to load the Youtube embed video): What You Can Do with a PedalPC? The desk can generate up to 70 W of electricity, depending on how hard and how fast you pedal. That's enough to power the following equipment: * a laptop or small desktop computer * monitor * inkjet printer * modem/router * desktop cooling fan * small web server ...while simultaneously recharging: * phones and tablets * AA/AAA batteries * battery-powered LED lights * other small battery-powered devices It CANNOT do the following: * power your refrigerator * cook food * run power tools These tasks consume more power than a person could comfortably supply. How It Works the primary parts of the PedalPC 1. You pedal the generator, which generates electricity. 2. The battery smooths its output, storing the excess you produce for use later when you're not pedaling. 3. The control box monitors your power production and consumption. 4. Four 12 V and 8 USB power sockets supply power to your equipment. 5. A small computer generates a dashboard you view with your web browser (see screenshot below--click to see the full-size version). PedalPC dashboard screenshot PedalPC dashboard screenshot Features & Benefits The PedalPC offers the following features: Dependable user working at desk in the dark The generator outputs the same amount of electricity, no matter the time of day or weather conditions outside. Accessible desk pivoted forward and user stepping over the generator prior to using it The desktop pivots forward to make it easier to get on and off. Adjustable [adjustable-desk] Both the seat and desk adjust to fit your body. Comfortable seat and mesh seat back The desk has a large padded seat and mesh back to allow you to work for long periods. Portable desk folded up and sitting on floor The desk folds into a compact size to make it easy to carry, with built-in rollers to make it easy to move. Durable seat adjustment clamp Made from rugged, rustproof anodized aluminum to last a long time. Comparison to Alternatives The PedalPC is not for everyone. If a high-intensity workout is more important to you than generating electricity, then you want an exercise bike, not the PedalPC. If you want to generate significant amounts of electricity in the most efficient manner possible at the lowest cost-per-watt, then you want an array of solar panels, not the PedalPC. But if you are moderately healthy, would like to generate modest amounts of electricity in any situation under any condtions, want a moderate workout without wasting time, and can tolerate a small amount of generator noise, then a PedalPC might be for you.
