Sports car made by Pakistani students to be unveiled today

Aluminium + Gallium + Water = Hydrogen

1370 litres of Hydrogen per 1 litre of Water!
Density of Water: ~1000g/L

So 1L of water has 1000g of water.

(1.008H+1.008H+16O) = 18.016 g/mol <-- Molar Mass of water

(1.008+1.008)/18.016 * 100 = 11.19%
Hydrogen makes up 11.19% of water by mass.

11.19% of 1000g = 111.9 g of Hydrogen in 1000g of water

At STP the density of Hydrogen is 0.08988 g/L so that means (111.9g)*(1L/0.08988g) = 1244.99L
Almost 1245L just to have a nice number.
No need for volts!

Aluminium is very cheap and readily available, and process of reusing that aluminium with new gallium coating is not expensive either. Gallium can be reused as well. Car has already been run with this reaction but as usual the guy and the kit he developed have disappeared.

Video from an airforce research lab ... thought this may be more convincing to those who believe public experiments to be fake.

The thing with this is...conservation of energy. So yes while extracting hydrogen from water and using that to power the car is a viable source of energy but why go the round about way?

According to the second law of thermodynamics u r bound to lose some of that energy initially put in to separate the hydrogen from water as heat. There is no point in first spending energy to separate water into hydrogen and oxygen...and then use it to burn hydrogen(react it with oxygen). So why not use that energy directly? As in battery powered cars.

This is the first car ever made and registered in Pakistan. It was designed and built by Hamid Omar in 1967.The chassis was built from angle iron left over from transmission tower construction. Metal body was all hand built.
It had a 200cc rope start pump engine. The cruising speed was 40 mph. Lambrettra scooter tyres.
Was in regular daily use for over 10 years. Was registered with great difficulty in Lahore in 1968. There is a story behind this, told by Hamid Omar:

"When I went to get this car registered, they wanted the Bill of Lading, the import documentations like the B/L (bill of lading), country, manufacturer. Since the car was made here, none of these papers were there, and they said that it is no car can be registered without these documents. There was no precedent – so at that time after lots of trips to various govt. offices, Lahore’s DIG Traffic finally agreed to inspect the car. He took a test drive around the block, and then gave the order to have it registered. I used the car for two years in Lahore and then three years in Karachi. Then Ahmad Omar used it for 3 years, then Taimur Mumtaz used it for a further two years. "
