 Pedals and cranks could be used for much more application than transportation. A bunch of machines could be directly powered by our legs. Instead of sweating in a gym, you could stay fit and use this energy to power your everyday tools. When you use a blender, the electricity usually comes from a power plant. The resources are in mind thousands of kilometers away and transformed into electricity which makes CO2 into the atmosphere or produces nuclear waste. Then the electricity runs through huge converters and cables down to your house. Eventually it spins an electric motor attached to the blades of your blender. What a complicated and wasteful way to make a smoothie. Here the power comes from my legs and my energy comes from the smoothie. It's too good. We have been in Guatemala to meet Maya Pedal, an organization that designed and made more than 3,000 pedal-powered machines for 22 years. At Lotec Lab we travel the world to find the best Lotec. Inventions that are useful, sustainable and accessible to all. What is the history of Maya Pedal? We had no idea how it was to be a soldier or to make a machine. The need to be able to solve the food for birds, the concentration, people were tired of paying, of going to the agro-industrial and buying and buying and buying. The native families of Guatemala have achieved a satisfaction by using an alternative like these. And sincerely, the motivation comes from the human heat. This is a bike. It extracts water from the wells. Normally in our community there are many wells, there are many communities that still don't get the water. So this is a very easy and very economical mechanism. It doesn't use electricity, it works with human propulsion. The machines solve, I think, 7 questions. One, the economy. That is to say, the person who uses an economic machine doesn't need to be buying expensive spare parts. He doesn't need to be going to a specialized technician. What can I do to repair it? It's a bike and all the parts are accessible in any part of the world. Everyone knows a bike. And that makes it more independent on the economic side. The part of health. Really, we human beings have forgotten to exercise. We are very stressed about making money, forgetting the family. And I think that when you have a bike, it makes you a more active person and forgets the stress. The other is the part of taking care of yourself. For example, I can put a bike in the road or I can put it on a route or in a park without having to have electrical connections. And that invites me to be able to sell my bikes or to be able to share with others. Each bike has a different process of assembly, of creation. Some are made of bicycle recycling from some containers that have been donated to the organization. And it's also made of metal. The Mayan Pedal works in two phases. The social part, the Mayan Pedal Association and the social company to transfer technology to organizations that invest in their projects. The family, a volunteer, a donor, and we are always running to help the communities. And that has given us life, and I think it's going to be more. The vision is to expand, so that more people can have the opportunity to be able to implement it in their city, wherever it may be. Because we cannot say that we can only use it here in Guatemala, but that it can also be used in different parts of the world. We work with open knowledge, that's the topic. And everyone would say, Mario, have you patented the machine? Mario, do you have a patent for each one? And I told them, no! I want everyone to use bicycles all over the world. There are so many creativity in the human mind that I know new bicycles are going to emerge. In the boat, we use one single bike to power all the machines. A drill machine, a blender, a mill and a sewing machine. There are four parts. The bike rotates the transmission that powers the tools. Everything is fixed to a workbench. To make it, you will need a bike, some pulleys, screws and nets, some rubber belts, wooden planks. The basis is made from an old bike. We cut the frame to keep only the back part. Remove the tire from the rim and find the belt larger than the wheel. You can choose to keep the gears or you can lock it like I did. The handlebar is plugged into the saddle pipe. On this bike, the handlebar was broken, so we replaced it with a wooden stick. Fix it to the ground. It's important to have a convenient workbench. Leave a hole for the belt between the planks. Build a seat at a suitable distance for peddling. Making sure you have enough room for your needs. But not too far to manipulate the tools easily. Screw two pulleys to the front bike hub. Screw the hub to the work surface with a piece of wood. It must be aligned and give a good tension to the belt. Many machines can be directly powered by mechanical transmission. For the drill machine, we just had to remove the old motor. Put a direct belt and screw some wedges. For the sewing machine, we had to screw in a pulley here. This is an 8-way belt because it has to spin the other way. For the blender, we had to make this adapter. The belt is twisted in order to change the horizontal axis to a vertical axis. The pulley is small to have a high-speed low torque rotation. I love this Lottec. A lot of our everyday machines could be nicely designed, ergonomic, very efficient and powered by our bodies. We should do more research on pedal-powered equipment. And my favorite is... The goal of the Lottec Lab is to find Lottec innovation. Document and promote them so that anyone can replicate them. It's open source and collaborative, so feel free to comment. And if you make it, share it with us.
