Do you own any solar panels yet? It is neat being able to recharge something just from the sun.
No, not yet but I will eventually
Solar backpack is a great idea. Do you hike? It would be great for someone who hikes.
I'm not usually a fan of hiking, I'd much rather ride my eBike.
That would be even better. Charge the battery on your ebike while riding. Neat setup that would be.
Welcome to the future. That's not even the half of it. 
What other cool futuristic ideas do you have?
A Time travel watch would be neat. 
James Bond style watch that lets you travel through time. Sign me up.
I know right, who wouldn't want that. 
A super villain trying to take over the world.
