The flower in the pic can produce rubber...imagine what would happen to our rubber industry if the process is perfected.
We are all aware of the low price of petroleum these days. This was caused by oversupply due to the United States of America suddenly becoming a net exporter of oil, the Arabs kept their production quotas high and China's economy slowing down. Oil is undoubtedly cheap these days but the surprising thing is that aside from pump prices being low, everything else is still high. I don't really see a 4 liter pack of fully synthetic engine oil suddenly being below RM100. Of course this could be down to production costs that aren't petroleum based. Again, something still has to maintain the overheads of the petroleum companies.
