If you start with the life cycle of hydrogen, from the time it is natural gas, reformed to hydrogen, then compressed you find quite a bit of wasted energy just to get it to be a (liquid fuel) fuel similar to gasoline which allows someone else to control the energy stream. With battery electric at least you have some choice as to where you get your energy and of course with a solar vehicle you provide the energy most of the time and when you can't you can charge from the grid. It's a no brainer. If you do the math Fool Cells come up short and are energy wasters. Just look at the EPA fuel economy website. Fuel cell vehicles are in the 60mpge range. The Leaf and other steel bodied cars are in the 112 to 120 range. The car in the article is built like a solar racer which is why it is in the 200mpge range..however a vehicle like Stella Lux is in the 600 to 1200mpge range. Plus it uses energy from it's solar panel..You only have to plug in when you want to give back to the grid. Lawrence Rhodes...

First, I think the capacitor may take the place of the battery, not the fuel cell. Tell me if I'm wrong. Second, depending on the battery, and depending on the fuel cell, a fuel cell may, though not necessarily be more efficient. Am I wrong? Lastly, I haven't had time to view the video, but the more important question is why they chose the combination. Everything isn't efficiency. High efficiency means nothing if it doesn't meet the needs of its intended use. - Mark Abramowitz (speaking for myself) President, Community Environmental Services Senior Advisor and Immediate Past Chairman, California Hydrogen Business Council Board Consultant to Dr. Joseph K.

Stella Lux and many Solar Vehicles use expensive in hub motors. They sound awful but get results. Stella Lux I believe made a record run over two days of 932 miles on one charge during the last World Solar Challenge but that was with the help of their 1.5kw solar panel. So more than half of their range came from the sun. If someone has heard of dramatic in hub motor failures please enlighten. The solar teams don't mention any of these problems. URL below has some specifications of Stella Lux. This is the vehicle they should make. Not a fool cell vehicle. However their EV design seems very efficient.
