偶然在網上看到一篇紐約時報(The New York Times, Jan 16, 2001)對Dr. Eleanor R. Adair關於微波的訪問，覺得其中用微波取暖的想法很有趣，故此分享一下。
(Q=The New York Times, A=Dr. Adair)
Q. Could you use microwaves as a way of heating yourself to stay warm in winter without heating your whole house? Would it be more efficient?
A. Absolutely. That was first proposed by Prof. Robert V. Pound of Harvard University. A lot of us had thought, Oh, gosh, wouldn't this be a great way to heat yourself in a cool house? He wrote the paper on it. It is known as the Pound proposal, and we are still pushing it as one of the peaceful uses of microwave energy.
Oh, I tried it twice. About four years ago, part of my liver was heated with an inserted radio frequency probe (microwave antenna) to "cook" the tumor growing in it.
The most concerning problem of the microwave heating of a human is the control of the penetration of microwave and to avoid heating up the internal organs. The second difficulty is how to avoid localized heating as different parts of our body absorbs microwave to different extents.
“Labeling includes the SAR (Specific Absorption Rate) value, which is the accepted way of measuring the amount of radiation energy absorbed by the head when the telephone is broadcasting at full power. We have also included TCP (Telephone Communication Power), which is a new method for determining the telephone's communication ability. A good telephone must use a large portion of its power for communication and as small a percentage of the radiation as possible should be absorbed by the head. A good combination, therefore, is a low SAR value and a high TCP value….”。
