Hello, my fellow steemian. I really appreciate your effort in reading my last post, upvoting and commenting.

I was ruminating on what to post when suddenly an idea occurred to me around 01:40 am today. I had to quietly shuffle out of the bed so as not to disturb my sleeping spouse. Actually, the idea was "Can cars really work on water?". So, I woke up my system, that is always on hibernation mode whenever it's not in use and logged in my Steemit account. I was now like this idea of mine about cars running on water can't probably be a new idea, I felt some Steemians too could have thought of writing on such.

So, I was forced to search through some past posts on Steemit and fortunately, I saw many posts of such. It was also somehow unfortunate (lol) because I was kinda un-motivated to surge on when I saw loads of great posts on the subject topic both old like a year old post of @realnews247 whereby he wrote that by using a litre of any type of water (even a cup of tea) is enough to power a car and also that of @greenrun that was written a couple of months ago. @greenrun on the other side talked about the growing risk of depleting the fossil fuel reserve, the pollution that's being released to the atmosphere and a better alternative in using water to power vehicles and the inefficiency of using water to fossil fuel.

I also saw some of the most recent posts on the topic, a good example is like that of @eurogee whereby he really took some time to give a more vivid explanation on fuel cells. From what I gained from the post is that truly cars can run on water but a whole lot of things have to be put in place such as changing from gasoline engine systems to that of electric fuel cells which is very similar to batteries. He also explained how fuel cells do operate so far as there is sufficient supply of hydrogen gas, It will keep producing electricity which is in turn used to power up the car. Water engines too have its disadvantages, some of which is the cost of running and maintaining it. Also, it isn't very efficient compared to gasoline and fuel engine.

However, despite all these challenges being faced with cars running on water, one Indian mechanic named Mohammed Raees Markani defied all odds. He is a 46-year-old mechanic from Madhya Pradesh, a state in central India having its capital in Bhopal. What makes it even more funny and interesting is that the man isn't literate like you and I. It's his passion that led to the invention. He has been working on the research for five years till he later made a scientific breakthrough. His type of car runs on the mixture of water and carbide to power its engine. When a calcium carbide is dissolved in water, an acetylene gas is given off.

Acetylene is a colourless and combustible gas which when mixed with air becomes highly explosive. The gas is mostly used as the fuel component in oxy-acetylene welding and metal cutting. A compound of Acetylene called acetylene black is majorly used in some dry-cell batteries.
So, it is this acetylene gas that Markani used to power his engine. He had to go through the stress of controlling and regulating the inflammable gas to his desired amount and then change the cylinder head and pistons of his prototype car.
