I think I will buy into Watering Cans, looks like it will be a big thing once we move to Hydrogen, ( although we have already seen developments of Water Fueled Engines dismissed).
Strange when the Water Based paint was first introduced they tried convincing everyone they had to purchase special bottled water @ £5 a litre,

it wasn't to long until someone showed them Tap Water works just fine.
P:S. love the Tesla, just haven't got the bottle to purchase just yet, if it were a company car choice I am certain I would go that way.
