Although I have to agree that mistake was made in writing fissile fuel instead of fossil fuel, as both fissile and fossil fuel are two different types of fuel, but most surprising is ability of some human minds that could not see simple errors and start considering such mistake as new technology. 
Anyhow, thanks for pointing out the mistake, as the level of knowledge we have in Pakistan, my mistake of writing fissile instead of fossil, some might start thinking that hydrocarbon based fuel like crude oil is really fissile fuel.
