about hydrogen is how light it is, with my idea the hydrogen if leaked would simply drift to the hatch and out. The floor is not air tight so the Hydrogen can escape if the vent system has a leak.

Does anyone have an opinion on drilling in vent tubes to each battery, and seal off the original vent holes. Run the vent tubes to a manifold and purg. Keep the vent tubes going up hill all the way.</div><span class="yiv8063873964HOEnZb"><font color="#888888"></font></span><div>
