Hi.
As title, I want to invent some new things to sell to global company(within Fortune 500).
Eventual purpose is earn big money(millions~ few ten millions).
What is technology that global company(let's say, samsung and apple) currently strongly want to get, but not achieved yet?
What scientific area is good(electronics, nano technology, chemistry, biotech, fusion of them, etc) and who are world class specialist in each field?
Thanks.
