crash-survive planes

what's the material black box is made of? in every plane crash it's usually the only thing that survives so why not make the whole airplane from the same material so that it also survives?

How to improve local food

Make local supermarket and grocery stores sales data available online so that local food managers can access them for a fee. By studying the data on grocery sales from all supermarkets and stores in the area food managers will get a pretty good idea of people's preferences. For example, if your local food deli or restaurant sells pasta you can find out from sales data which types of spaghetti sauce people in your area buy the most. First make sure that you offer them in the menu and then work on improving their taste.

Special glasses for laptop use in plane

Some airlines (Delta, United, Virgin etc) are rushing to offer Wi-Fi internet connections in economy. Most people cite cramped space on the tray table as the major problem for laptop use in a flight but I think privacy is a more serious problem. Text chatting with my girlfriend or friends, I wouldn't want the guys sitting next to me reading what I write. We are all curious creatures by nature and easily tempted to read into everything that gets displayed on someone else's computer screen.

One way to solve the privacy issue is with special use glasses that the passenger puts on to watch what is displayed on the computer screen which stays turned off. I looked up online and found out that head mounted display glasses already exist. They connect to common video sources and are ideal for mobile entertainment and information applications.

I expect that as in-flight Wi-Fi becomes available and people take their laptops with them, there will be a big demand for use of such glasses to protect privacy. I think it's a smart investment to buy stocks of companies that make them.
