I just took a quick look at their deal with Plug Power and you are right this is a recent, large deal and looks like it is very long term. I am assuming they are working on a forklift deal with someone in the retail and distribution area. Some time ago I asked IR about the retail and distribution deals they were working on and I asked if it involved forklifts, I was told that it was actually for solar power for the distribution warehouses. So this is a possibility for Walmart as well.
