And do a LOT more walking. Ever with the most effificnt solar cells and a vehicle 100% covered in them the amount of energy converted will be small in compairson to what we "normally" spend going down the road.ElectricTroy said:In the LONG term, I think if you're going to use solar panels, don't waste time with hydrogen. Just use the solar panels directly:
- An EV
- married with a small engine (hybrid) for distances over 40 miles
Don't waste time converting solar-to-electricity-to-hydrogen. Use the electricity directly.

Solar ---> Electric ---> Battery ---> Move the carElectricTroy said:I was talking about solar panels on your roof [of your house], feeding into a battery. Like 99.9% of all Electric Owners do. Use the electricity directly, and skip the hydrogen conversion step.
As Scotty used to say on Star Trek,ElectricTroy said:I saw a REALLY good green program on Discovery channel last weekend. The host of the show, who is an environmentalist, asks the question:
"Fuel cell cars are great, but where does all the hydrogen come from?" He then points out the great flaw: "In order to drive this [Honda Fuel Cell] car just 200 miles, requires a week's worth of solar energy, with a panel the size of two homes." (quoting from memory).
Can you share those numbers?b1shmu63 said:"but where does all the hydrogen come from?"
One of our own IC members did the math and proved that an advanced system could provide the typical energy needs for a vehicle using just the surface area of the vehicle.
