Idea to make more safety of the flights

Here are my ideas to make more sure the flights :

Idea to make more safety of the flights :

1. Use alternative air craft engine in same plane so that fail over will take place. Because most of accidents or crashes took place because of failure of the engine. Can't manufactures deploy another engine and other apparatus so that if one fails, other will instantly take care of the flight?

2. Implementing above idea could cost a lot. Instead of above solution, can't we attach a big parachute so that it will be automatically opened once air craft engine fails and comes to the contact of air? The process should be automatic. And flight or plane should contain two parachutes so that fail over technique will take place. Pilot should be able to control and manage the parachute in order to land the flight.

Thus we will save people's life as well as whole flight.

FYI :

[ I have been heavily shocked by Nigerian plane crash. I have also faced a tremendous situation while I was flying from kolkata to Pune via Delhi. Plane suddenly came down for 10 KMs when it was taking off at Kolkata airport. Even similar issue happened when it was planning to land at Delhi. We later heard from pilot that plane was going through horrible condition because of bad weather :( ]
 

Run data ceneter using solar power and save energy ?

Hi guys,

Can't we design data centers or systems so that they will consume solar power. Thus electric consumption will be very less. So, we will save more energy. As an example we use LED lamp now a days instead of normal lamp in offices. Same can be applied in data centers too.

Mobile sized laptop or computer

Can't we create mobile sized laptop which should be expandable to laptop as we use now a days(15 - 20 inches)? It should include all features as current laptop's OS contains. Portability should be excellent. And it should have a very less power consumption and capability to recharge automatically from sun light or normal day light.
