He's pushing the envelope for sure. Questions. How long does the battery last? How long does the blender last? How heavy is it loaded? To me the only new accesory to the cooler world is the blender. You can buy frozen drinks already made and just keep it in the ice, hello. I'm thinking a small motor on a little larger chest, remote controlled with a storage rack on top. Kinda like the moon rover. You drive it off the ramps out of your truck bed to the beach, hunting camp, etc. When your battery starts to die, start up the engine/generator, put it in neutral, and charge the battery back up. I need a 1000.00 kickstarts.
You need to add an air compressor to charge the inner tube so that you have a floating ice chest/radio/blender/generator/shitter. Now we just need to find somewhere for the ice.
