Hello, I'm doing a project on SBSP and we have a few months to complete it, and in my written report I will be going over NASA's data they collected from their attempts. Calculating efficiencies and otheer variables between different stages of transmission, e.g. first from the sun radi to PV cells to generate electricity, then to power a microwave transmitter, which is beamed down to Earth taking into account gravity/atmosphere etc, then the receiver converting it back to electricity, then to AC/DC inverter. Talking about feasibility (launch cost, micro asteroids etc) Okay so now I was talking to my lecturer, and I gave him an idea of me creating a scaled down version of the satellite (which will basically be 1 of the PV cells which would go in space), to a table top experiment, one I figure out the calculations in the written I can scale them down, thus get a high powered lamp or lamp's trying to replicate the sun's solar radiation. I'd also have a small microwave transmitter, transmitting the microwaves about 1-2m across to the receiver, with measuring equipment for voltage/current and microwave radiation during the stages. In the end, all my data scaled down should follow similar patterns if were in space, though not exactly, as it's more of a proof of concept My supervisor told me I need to be a bit more detailed if we are to continue. So aerospace engineers, anyone mind throwing some ideas around. I looked at NASA's data and their is a 0.4% energy loss with microwaave coming through the atmosphere, thus my idea is to just use a light material to account for that .4% loss and any gravitation effect in the form of refraction from the material for the microwave. So yeah, just throw any ideas around for me for this project. I am thinking of enhanced chromium PV cells, anyone think of any else? Does my practical project sound reasonable to you, what microwave transmitter could I use? Am I missing anything in the theoretical part, I also had an idea from what I read on the net that I could use laser transmission instead. What's your take guys?
