Space Based Solar Power

Which of the following sentences helps the reader understand the advantages of space-based solar power?

• The idea of capturing solar power in space for use as energy on Earth has been around since the beginning of the space age. 
•    In the last few years, however, scientists around the globe -- and several researchers at the Energy Department’s own Lawrence Livermore National Laboratory (LLNL) -- have shown how recent technological developments could make this concept a reality.
• In space the sun is always shining, the tilt of the Earth doesn't prevent the collection of power and there’s no atmosphere to reduce the intensity of the sun’s rays. 
• This makes putting solar panels into space a tempting possibility.

How is this section of text organized?    
How does it work? Self-assembling satellites are launched into space, along with reflectors and a microwave or laser power transmitter. Reflectors or inflatable mirrors spread over a vast swath of space, directing solar radiation onto solar panels. These panels convert solar power into either a microwave or a laser, and beam uninterrupted power down to Earth. On Earth, power-receiving stations collect the beam and add it to the electric grid.

• chronologically
• sequentially
• in cause/effect format
• in problem/solution format

What two categories does the author set up and compare?

• space-based solar power and earth bound solar power
• geostationary orbit and low earth orbit
• microwave transmitting satellites and laser transmitting satellites.
• Lawrence Livermore National Laboratory (LLNL) and NASA

Additionally, SBSP can be used to get reliable and clean energy to people in remote communities around the world, without relying on the traditional grid to a large local power plant.
What does remote mean in this context?

• a device for controlling electronics
• poor
• villaige
• rural

What is the main idea of the text?

• Solar power is the key to clean energy.  
• Space-Based Solar Power is far superior to traditional solar power. 
• Space-based solar power is not likely to replace traditional solar power anytime soon. 
• space-based solar power is a promising technology, but many challenges must be overcome before it can become a reality.
