[Spridgets] hydrogen filling station in Los Angeles

[Dave G.]

When I was quite young, during WW2, gas was severely rationed and only 
for those with a war-related need (or buying Gas coupons on the Black 
Market !)...
I remember cars driving around with inflatable gas-bags on the roof...
But I think they were filled with something like propane...
 
With todays high pressure cylinders there could be a neater installation... 
but I almost had another heart attack when I found out how much it cost to 
fill the propane tank for my gas BBQ...
