Google Navigation Meets Ride Share

I would love to see indicators along my Google Navigation route showing people I could pick up and drop off along my route.  Seems like a no brainer to compare routes on the cloud and pair them up.

Launch Objects into Space

Much like the child who cannonballs into a pool to create the largest splash, fluid action can be used to transfer energy from a larger object to a smaller one. I propose building a gigantic cave in the Earth. Two tube-shaped tunnels can be bored vertically into the cave. One tunnel should be significantly larger than the other. An immense weight can be hauled up, suspended, above the large tube. A smaller object can be placed snugly inside the smaller tube. When the large weight is dropped, it accelerates and enters the large tube, displacing a tremendous amount of air. With no where to go, the air will drive the small object up the small tube and, hopefully, into Earth orbit.

Facebook Should Buy Craigslist

About 6 years ago, I attempted to build a Social Media site that combined all the beautiful parts of MySpace with all the best parts of Craigslist. It was awesome.... to the degree that I was ever the only member. What I thought brilliant of my idea was that it leant credibility to the items listed for sale to have the persons Social Media account bound to the item.

If Facebook were to buy Craigslist, they could put Craigslist Items on an "Items for sale by me" page. Craigslist could add credibility to it's listings by verifying the person's identity with their Facebook account. If someone ripped you off by selling you a car with a Lien on the title, you could track them down through their friends list. Also, when you posted an item for sale, you could send it instantly to all the friends on your friends list.
