I am very interested in how the batteries are being changed out in 2 minutes. Normally it takes about 10 minutes from start to finish to change out. You have to have a power room with chargers, extra batteries (normally 2-1), cranes for lifting and moving batteries, watering processes, drainage cleaning, battery replacement at approx. 5 years of life, water filtration systems for clean water.

Hydrogen is the number 1 element in the universe and is will become even cheaper in the near future. There are several ways to get hydrogen and the cheapest way is by solar, steam separtate and then hydrogen. Storing the hydrogen is the biggest problem right now and there are many studies to solve those issues. Hydrogen is here and the steam engine is slowly picking up speed. Batteries will still have there place with smaller applications.

RayTech - please do a little more research and look for hydrogen system to be intergrated into the lifts as 1 piece of equipment that you fuel that should last for a couple of days per fill up. Tank capacities will increase and think of the possibility of only adding water to keep the forklift running. It is possible with H2.
