I'm in need of an engineer with expertise in both electrical and mechanical engineering. Our aim is to design a high-power attachable biking dynamo/alternator for bicycles. The primary objective of this project is to create a device that can generate and store significant power for storage in high-capacity batteries. This dynamo/alternator should deliver a high power output, mainly focusing on efficiency, ease of use and weight. Key requirements: - Designing a high-power dynamo/alternator that can support extensive power needs. - The device should be attachable to a standard bicycle without impacting its performance or aesthetics. - Prioritizing power output over size or weight, meaning the final product can be robust as needed. Your role will be to: - Combine your expertise in electrical and mechanical engineering to create a prototype. - Ensure the final product is not only functional but also practical for cyclists to use. - Potentially provide suggestions on storage solutions for the generated power. Ideal skills and experience for this job include: - Proven experience in designing high-power dynamo/alternators or similar energy generation devices. - Knowledge of both electrical and mechanical engineering principles. - Familiarity with designing for bicycles or other sporting equipment would be a plus. Interview questions below are mandatory: Q1: If current dynamos range between 3W to 7W, but alternators can go up to 100W. Can you make use of existing technology to capture up to a 100W from biking? (For instance using more then one dynamo or alternator or combining both) If yes, how? Q2: Can you create a hybrid system (an in between-system that can be mid-range between producing the low watts of a dynamo and the high watts of an alternator)? If yes, how do you aim to achieve this? Q3: Are you able to optimize the energy capture and storage efficiency of the system in a lightweight manner? (no more then 1kg - including batteries). If yes, describe in brief how you will achieve this? Q4: What technology can you make use of to maximise efficiency in the system and minimize energy loss? Q5: Based on all your responses previously provide a breakdown of the estimated design costs, implementation needs, and timeline required to achieve a functional prototype? Q6: What can you deliver in two weeks as a proof of concept? Provide detailed description, breakdown of deliverables and rate

DearSir, My name is Metin and I have extensive experience in electrical and mechanical engineering. Throughout my career, I have managed a wide range of projects involving renewable energy solutions, power electronics design, and electronic systems. As an engineer experienced in digital motor control, I'm well-versed in optimizing power output while considering efficient storage. This skill will be highly useful designing your high-power attachable biking dynamo/alternator. When it comes to energy generation devices, thinking out of the box is crucial- which is what makes me differ in my approach from other engineers. Combining both dynamos and alternators can significantly increase the Watt production according to your needs. Furthermore, my skills in Analog Design, Electronic Design, PCB Design along with solid knowledge of Hydraulic Energy Capture Systems can help bridge the gap between dynamic differences as a mid-range solution. My focus has always been on delivering not just functional but practical designs that are efficient. By leveraging my expertise in lightweight Electric design integrated with Batteries having better self-discharge rates, we can achieve high-energy capture and storage efficiency within your weight restrictions for the system. On another note, I can use this opportunity to employ FPGA Technology which significantly maximizes efficiency while minimizing energy loss.

As an accomplished engineer with a decade of experience in electrical and mechanical engineering, I believe I am the perfect fit for your project to design a high-power attachable biking dynamo/alternator. In fact, my team and I have already designed similar energy generation devices and understand the delicate balance between power output, size, weight and cyclist needs. To address your interview questions directly, we have the capacity to combine multiple dynamos or alternators strategically to capture up to 100W from biking. Additionally, we can develop a hybrid system that leverages the strengths of both dynamos and alternators - a solution that can produce mid-range watts without compromising on efficiency. Our main goal is optimizing energy capture and storage efficiency in a lightweight manner. We've continuously applied innovative technology and engineering techniques in our designs to minimize energy loss while maximizing overall efficiency. As such, we are confident that we can design a high-power biking dynamo/alternator within the desired weight range of not more than 1kg - including batteries.

As an experienced engineer specialized in mechanical and electrical engineering, I couldn't have requested a more fitting project then your High-Power Attachable Biking Dynamo Design. I'm well-versed and skilled in combining my electrical and mechanical knowledge to create prototypes that go well above the mere "functional". Having already dealt with energy-generating devices like dynamos and alternators, I am attuned to the need for efficient design while balancing weight that's critical in biking technology. To address your project specifics: First and foremost, yes, I am convinced I can capture up to 100W from biking by combining current dynamo technology, or even devising a hybrid system to achieve mid-range energy production between dynamos and alternators. I strongly believe in optimizing energy capture and storage efficiency in a lightweight manner. My past experiences in such designs have taught me how crucial it is to be mindful of weight. Weighing no more than 1 kg, including batteries, is definitely achievable.

Hello! With a knack for problem-solving and a demonstrated track record in both electrical and mechanical engineering, I relish the challenge your project presents. Not only have I successfully designed high-power dynamo/alternators previously, but I also possess uncommon insight into creating energy generation systems that cater to specific needs. Given the increment from 3-7W dynamos up to 100W alternators, I propose incorporating any combination of dynamos and alternators, thereby capturing the maximum energy output possible. My multidisciplinary approach is rooted in efficiency, making use of existing technology intelligently. In line with your request for a 'hybrid system', an intermediary between dynamos and alternators, my proficiency will play a crucial role. To create this mid-range solution, I plan to effectively balance mechanical components and electrical aspects, maintaining robust power generation that doesn't compromise the bicycle's performance. Additionally, my expertise in optimizing energy capture and storage efficiency won't falter even under the constraint of maintaining lightweight designs (no more than 1kg - including batteries). Through meticulous calculations and strategic component selection, I can ensure that efficiency is maximized and energy loss is minimal. Thanks
