    Flying Hoverboard
AI Thread Summary
The discussion revolves around the feasibility of creating a hoverboard inspired by a fictional device from Ben 10. Key challenges include selecting an appropriate thruster that can lift a total weight of around 80-90 kg within specified dimensions and finding a suitable power supply for a flight duration of 5-10 minutes at heights of up to 100 meters. Suggestions include using jet engines, with concerns raised about stability and safety due to fuel requirements. The possibility of utilizing advanced technologies, such as a fusion reactor or the Space Shuttle Main Engine, is debated, with skepticism about their practicality for such a small device. Overall, the conversation highlights significant technological hurdles in replicating a hoverboard-like device.

So, some days ago I was rethinking my childhood and remember that I was obsessed with ben 10, particularly with the hoverboard in the film (https://ben10.fandom.com/wiki/Hoverboards). Right now, I really want to construct a replication of it, but I am stuck with some problems. First, what type of thruster that would fit in a 1m*30cm*10cm dimension and would be able to lift a 70 kg person and itself (maybe 10-20kg) . Second, what power supply should I use to make the hoverboard fly for maybe 5-10 minutes. I am thinking that it would fly up to 100 meter above ground. If you have a suggestion, I'm hoping you could answer me.

Your link says "Hoverboards are a type of technology, typically alien in origin" (emphasis mine). Therein lies the problem.

Well yeah. Do you have any brilliant ideas to imitate that device?
 
Based on that description, I'd start by finding an alien.

Hmm, bringing a bag of fuel every flight doesn't seem very stable and safe. Do you think if a fusion reactor exists, it could be made into a small enough size to fit in the previously mentioned dimension and have the power to fly? Maybe it will function as the combustor and pressurizer at the same time in a modified turbojet engine.

Maybe after 1000 years of refinement in design. Using near-term technology no way. A building the size of a football stadium would be closer.

Okay, but how about the Space Shuttle Main Engine (RS-25)? I heard that it has one of the highest power-to-weight ratio. Could it be used in a small device like hoverboard? What are the possible advantages and disadvantages of it?
