Can we convert Lightning into Electricity ?

One lightning strike will produce around $100 worth of electricity, whereas it will cost millions of dollars to build such towers which can regulate such high voltage. If we see the data, there are about 7 lightning strikes per year per square mile. To capture the strikes in one square mile you would need dozens of 250-1000 foot high towers, & all of them having very costly capacitors at their base. So, I think its not a good idea.

How do Ships float in water ?

According to the  Archimedes principle , " an object in a fluid experiences an upward force equal to the weight of the fluid displaced by it. " The same principle goes for the floating ships. The reason ships float is that they displace a lot of water, if a ship could not push enough water out of the way, it would probably sink. The displaced water wants to return in its original form, where the ship is now, & keeps pushing it upwards. As a result, we get a smoothly floating ship. The force which pushes the ship up is called the buoyancy force. Designers keep it in mind that the ship will displace the total amount of water equal to its weight, way before the water gets in.
