Arvind, i have actually heard what you said. I dont remember which company but there is already lot of R&D going on in this. But again, i had heard this sometime 5 years back. I wonder whats happened to this research. However, let me tell you, this concept is nothing new when thinking of Hindu ancient history. Any technology is appreciable only if it does not pollute or may be, it pollutes only in a negligible manner. Even hybrid vehicles need batteries, which again means, necessity of fuel though in a different way. I think, there is gulf politics in R&D of non-fuel vehicles. Indians pay Rs60 per litre of petrol while Pakistan and Bangladesh do just half of that (and that too, their exchange rate is so less!).
