I drove 1800 miles in a Hydrogen Car

No its not, (where does the hydrogen come from??) it's carbon fuel being refined, reused and pushed into hydrogen in a clean driving car.  It is the last gasp attempt by the fossil fuel industry to keep drilling and refineries and pipelines filled and active.  Dive a little deeper please.  You are losing science cred here.  You are being played. 

OF COURSE your emissions are down to zero...unless you track the carbon emissions from delivering hydrogen, then you are just proving your naivete'  I will tune in to your other videos looking for you to "Physics Girl 'Splain" it to me.
