Radiation pressure, photon momentum, and solar sails?
by NASA’s Marshall Space Flight Center Question by thisislizz: Radiation pressure, photon momentum, and solar sails? So I understand that a photon can have momentum, but how is this momentum is transferred to an object off of which it reflects? Once the photon bounces off an object, it does not slow down or change wavelength […]

Solar Sailing
Would you like to get around in space using only the energy from the Sun? Watch the HR MacMillan Space Centre demonstrate this idea of solar sailing. A renewable energy source is needed for deep space travel and this might just do the trick. sfx by Cosmic D Video Rating: 0 / 5 The Zephyr […]
Q&A: Would it be possible to power an energy star light bulb using the light it produces and photo-voltaic cells?
by micropig Question by ME: Would it be possible to power an energy star light bulb using the light it produces and photo-voltaic cells? Follow-up. Say you have a lightbulb on a seperate power source shining its light on a single photovoltaic cell. If you added a second cell to the first, does that multiply […]

Solar Power from Space
Solar Power Satellites (SPS) are fairly large structures in space that convert solar energy, captured as solar irradiation, into an energy form that can be transmitted wirelessly (Wireless Power Transmission – WPT) to any remote location with a receiver station, either on Earth, to high altitude platforms, to other spacecraft or even to surfaces of […]

besides batteries or solar cells or fuel cells, or generators what else is there that can produce high voltage
when I was younger, I used to think that Nuclear Power Plants used nuclear material to collect electrons, but now I know that it’s only the heat given off that creates steam which turns a turbine. HOW LAME! Why can’t we use nuclear material to create electricity directly? Or maybe even replace electrons altogehter.. replace […]

Can anyone recommend solar cells and solar panels for a physics experiment?
I am doing a physics experiment where I need to compare the efficiency of the two. Solar panel for radiation>heat water and solar cells for radiation>electrical energy. Can anyone recommend me some cells and panels which have lots of information about their performance, efficiency etc? Many thanks!
