This is Kim in Korea.
I have been pursueing fuel savers for Korean market.
HHO has been tried. So far only 10 % level saving at very high price of over usd800 in Korea. Too high cost is not accepted in the market.
I tried neww fuel injector . But no investor.
I tried atomizing device. But too high cost of usd500-600 in the market not acceptable.
Now i am trying hydrocarbon cracking system. Price is attractive. Results to be seen soon.
If you have any good seller in fuel saving, please let me try it in Korea.
Korea has vast market also in a so narrow land full of vehicles of over 15 million.
