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 geo-
synchronous(与地球同步的)orbit. Earth-based solar cells , by contrast , can only collect sun light during day-
time 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 in-
to 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 mir-
rors 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 radia-
tors to help keep them cool.
Though Boerman says the company believes it can make space-based solar power work,it is not expec-
ting 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.
One advantage of the space-based solar power system is that it is economical.

[单项选择] The Problem of Scarce Resources
The problem of how health-care resources should be distributed, so that they are distributed in both the most just and most efficient way, is not a new one. Every health system in an economically developed society is faced with the need to decide (either formally or informally) what proportion of the community’’s total resources should be spent on health-care; how resources are to be apportioned(分配); what diseases and disabilities and which forms of treatment are to be given priority; which members of the community are to be given special consideration in respect of their health needs; and which forms of treatment are the most cost-effective.
What is new is that, from the 1950s onwards, there have been certain general changes in outlook about the limit of resources as a whole and of health-care resources in particular, as well as more specific changes regarding the clientele(委托人) of health-care resources and the cost
