Now a man that is true to his word still has 6 more days to unveil this 'secrete" phenomena. After all he did say next April in 2018. But did not state which date.
Guess we will find out May 1 if the word has been kept.

I'm still wondering if the folks in the Netherlands are still running their buses on ammonia - some how I think they opted for a "fossil fuel" once it be came available again after WWII. The "Exhalted One" went quiet on my legit inquiry.
One can do unique things but the infrastructure to support them must be in place before it can be a real solution. One reason all electric cars are not a solution - too short of a distance to run on a full charge and too long to recharge - not to mention the economics of ownership - high up front price and low trade-in or residual value (those battery banks ain't cheap to replace and no snake oil can "rejuvenate" them. Kinda' like the history of any brand of battery powered lift trucks for as long as I was around the business since 1967. As late as 2005 I sold used equipment both retail & whole sale. In the wholesale market a 5 year old 5 K ICE solid tire truck would run at least 3 times more than an equivalent 5K solid tire electric w/battery & charger - both in running condition, fully functional & operational.
Just one more thing that ain't to clear. Exhalt claims it only takes 4 hours to exchange one of those modules. Maybe that is true. But what puzzles me where are these "extra" modules located - I assume at some stocking point some where close to the point of manufacture or close to the point of use or maybe on the next continent. If it ain't close to the point of use then their is some added time for shipping & receiving, maybe customs issues, etc. etc.. So down time "might" be minimal or it might be very extensive. The larger the fleet in use the more complicated it be comes for the manufacture. to keep the end user up and running. In my tenure with Alis-Chalmers during the Lancer Boss agreement era (1970 thru 1982) product support was nothing but a large PITA. Often parts were air freighted at no cost to the customer & Sir Neville Bowman did not like to eat but he did.
Every thing always looks good on paper.
