用微波取暖

LLH

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.

Good idea.

But no thanks. It may be a little bit dangerous

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.

歐盟一向很重視電器產生的電磁場 (包括 50Hz 以下的極低頻 和1~10 GHz 微波) 對人體健康的影響，現時歐盟合格的電腦、顯示屏、手電等都要乎合 TCO 標準，它其中一項 Emissions 標準要求是這樣寫：

“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….”。

所以，
不要將手電長期貼近腦部煲電話粥，
電腦用的 wireless router 要在身體最少一米距離之外，
睡覺時頭部不要鄰近電視機 (即使機停開，它的內置電源也會發出輻射!)

香港出售的消費品，有些博晒老懵，都係小心為著

原因如下:
1.機器會壞,有一天它特然失靈,把全屋人都煮熟了.
2.個身好暖,但所有物件都冷冰冰,坐入椅子或拿起工具都凍到大打噴嚏.
3.全屋人都是熱源,慢慢地全間屋都會熱起來,無乜省電,只不過你做了個會走動的暖爐罷了.
4.現代人,要減肥,冬天屋內冷些,身體要燃燒更多卡路里去保持體溫,有減肥之效.上述方
法只會製造更多會走動的肉團,命都短D.....
