electricity hungry（回答）
ご指名にお答え致します。http://d.hatena.ne.jp/A30/20130118/1358482860
まずここでのhungryは「空腹の」ではありません。『ジーニアス英和辞典 第４版』(大修館)の第４義における「…を強く求める」に近いと思います。つまりボーイング787機が「（ブレーキもコンピュータが制御するため）電力を多く必要とする」という意味でしょう。
教えるのは難しいです。中学生なら「空腹の」はおそらく知っているはずです。そこから、「…を渇望する」という意味になることを例文で気づかせてあげたいと思います。例えば、”She is hungry for success.(LDOCE)”を見せて得意な子は気づいてくれるかもしれません。苦手な子には「ハングリー精神」という言葉を連想してみたりします。
そこで、記事をみせてBoeing 787機は電気を「渇望する、強く求める」とはどういうことかを一緒に考えます。Boeing787機はブレーキとかもコンピュータで処理するからすぐ「お腹がすいてしまう。」など比喩的な表現も交えながら導いてあげたいと思います。(Minnesota)
Japan-made battery under microscope after Boeing 787 fires
With all Boeing 787 Dreamliner jets registered in the United States and Japan now grounded by government regulators after a second fire aboard one of the aircraft on Jan. 16, attention is now turning to the Japan-made batteries at the heart of the malfunctions.
The 787, which made its commercial debut in All Nippon Airways (ANA) colors in fall 2011, is outfitted with four sets of lithium-ion batteries produced by car and motorcycle battery maker GS Yuasa Corp. The firm began making the 787 batteries in 2010, shipping completed units to French firm Thales, which adds the battery charging system.
According to GS Yuasa and related sources, the firm's lithium-ion batteries are unusual in that they include cobalt, making them lighter than lithium-ion units in electric cars -- which include manganese -- and about half the size and weight of previous nickel-cadmium batteries. The weight savings are what made the GS Yuasa units a good fit for the 787, which with its carbon fiber composite body and components was being marketed as a uniquely light and fuel efficient aircraft.
With virtually all the Dreamliner's systems right down to the brakes controlled by the plane's onboard computer system, the 787 is electricity hungry, and most of that power comes from the GS Yuasa batteries. The batteries also supply the auxiliary electrical systems for when the plane is parked with engines off, and provide overall backup power.
