California Gives Green Light to Space Solar Power
Energy beamed down from space is one step closer to reality，now that California has given the green light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatts(兆瓦)of power beamed down from solar-power satellites beginning in 2016．But some major challenges will have to be overcome if the technology is to be used widely．
A start-up company called Solaren is designing the satellites，which it says will use radio waves to beam energy down to a receiving station on Earth．
The attraction of collecting solar power in space is the almost uninterrupted sunshine available in geosynchronous(与地球同步的)orbit．Earth-based solar ceils，by contrast，can only collect sunlight during daytime and when skies are clear．
But space．based solar power must grapple(努力克服)with the high cost per kilogram of launching things into space，says Richard Schwartz of Purdue University in West Lafayette，Indiana．“If you're talking about it being economically viable for power of the Earth，it's a tough go，”he says．
Cal Boerman，Solaren's director of energy services，says the company designed its satellites with a view to keeping launch costs down．“We knew we had to come up with a different，revolutionary design，” he says．A patent the company has won describes ways to reduce the system's weight，including using inflatable mirrors to focus sunlight on solar cells，so a smaller number can collect the same amount of energy．
But using mirrors introduces other challenges，including keeping the solar cells from overheating，says Schwartz．“You have to take care of heat dissipation(散发)because you're now concentrating a lot of energy in one place，”he says．According to the company's patent，Solaren's solar cells will be connected to radiators to help keep them cool．
Though Boerman says the company believes it can make space-based solar power work，it is not expecting to crowd out other forms of renewable energy．Laws in California and other states require increasing use of renewable energy in coming years，he points out．“To meet those needs，we're going to need all types of renewable energy sources，”he says．

Solar Storm
At the end of October 2003, a sudden solar storm hit the earth. A solar storm refers to the large amounts of charged particles released into space______(51) the solar energy increases. The release of the energy______ (52) place along with the activity of the sunspots with a cycle of: 11 years. This time, the______ (53) of the storm exceeded expectations.
This______(54) of intense solar storm was caused by the eruption of a solar flare (闪光) and the ejection (喷发) of the solar corona (日冠) on October 28, 2003. Large amounts of charged particles moved 150,000,000 kilometers through space toward the ______(55) in 19 hours. They could affect aircraft roaming (漫游) in space.
The high-energy particles will______(56) some of the parts of an aircraft. They may also cause it to fail. High-energy particles can threaten the safety of an aircraft at a high orbit. If an aircraft orbits at a lower orbit, it is______(57) because it is under the protection of the earth's magnetic field.
A solar storm not only affects aircraft but also is a ______(58) to the environment and humans. The aerosphere and magnetic field of the earth can______(59) humans from ultraviolet radiation and X-rays. While most of the X-rays are absorbed after they enter the aerosphere (大气层), still a few can______(60) the ground.
The geomagnetic storm caused by this round of solar storm reaches its highest level on the two______(61) of the earth, which affects electricity supply of North America. Overexposure to______(62) threatens the health of passengers on planes flying over the Polar Regions. If we fly in the sky during such a solar storm, it______(63) we receive ten times the X-ray radiation. It's really damaging.
Scientists say a solar eruption is like the sun sneezing, which will make the earth______(64) a cold. Though this natural force is irresistible, scientists can still______(65) its movement accurately by monitoring. Facing successive solar storms, humans can't drop their guard.
A．since
B．when
C．until
D．though
