A ten part video series on energy: Where does it come from (what are our typical sources?), how does the power grid really work, does the grid need to become smarter? What is the status of alternative energies: nuclear, solar, wind, geothermal, passive houses. How do they work? What technical obstacles lie in the way?

Please add comments, suggestions, points for discussion below. Also, feel free to modify the description above.

  • solar to electricity: what are the current methods. this area is still in flux. economics plays a big role. how efficient is it (compare to other methods). blend between engineering and business for a huge upcoming industry. also, how this leverages previous industries (semiconductors)
  • in a nuclear disaster, how hard is it to clean up. how do they do the clean up? what needs to be cleaned up? in japan, what happened after the tsunami? why did the enclosing building blow up from hydrogen? (more generally, beyond engineering for engineering sake and more focus on important issues of the day and their engineering perspective).

  • What is the role of water and steam in todays energy conversion (or how to get from "chemically stored" energy in coal, oil and gas to electrical power from the socket)?
  • How does a steam turbine work ? How does a gas turbine work ? What does boiling water look like ?
  • How can you store 800 MWh for later use (this is the hourly electrical energy production of a typical power plant) ? Can you do it with batteries ? What if that is not possible ?.

  • If e=mc2 what does that mean about energy? Is energy light? Is energy mass? Is energy photons? Is energy the movement of particles and transference of that movement?


Really nice info on energy, thanks.

There is a great presentation by Shai Agassi on the TED site about the way thinking big and using infrastructure makes electric cars practical and ubiquitous. To me it is a real insight into the way we approach clean energy, transportation and a brilliant way to conquer the battery issue.
