我今天的英文功課是：3D food pringting。

食物可以列印？

  真的，美國太空總署補助機械工程師研究製作"食物合成機",也就是他們說的"食物列印機",它使用營養粉匣,將營養粉混合水和油,製造出一種可食用的材料.一開始是為太空人研究,但未來可能發展為人類的食物供應.

  我一直和Jeff老師說,我認為是food maker.但他仍認為應叫food printing.

 1. NASA gave a mechanical engineer a grant to make a universal food synthesizer食物合成器.

2. It would use cartridges of nutritional powders and mis them with water and oil to produce and edible material.

3. NASA wants to use this for astronauts.

4. If this technology works, it would be a great way to feed people on earth in the future.

5. Overpopulation is cause food shortages, if they perfected this technology it would be so convenient.

6. We hope they don't  have to resort to dead people(死人) to get the materials for the universal food synthesizer cartriges.

7. They use insects(昆蟲) and algae(藻類) are a good possibility.

Maybe some day we had a universal food synthesizer in our home. We could just touch a button and order anything I wanted.
