He did clarified normal hydrogen kit we used on motor vehicle will generate a small amount of hydrogen that spray into the intake system, some of it already leaked out. The remainder helps to improve combustion, whereas the others will be release to the atmosphere. Therefore, without a STORAGE/PRESSURE tank to store the hydrogen,
