We're all for alternative energy and all that, but it's not too often that we see a green technology that we must have. And if you drive, we suspect that you may feel the same way about the "Sunsei SolarCharger."
Manufacturer ICP Solar says the solar panel will keep your car battery perennially charged with energy from the sun as long as you keep it on the dashboard or attached to the windshield. SCI FI Tech says its "trickle-down" power is meant more for maintenance than regular charging, ensuring that any 12-volt battery is full without overcharging it. All we know is that, if it saves us a single towing bill, it's worth it.
