Noise Cancellation Earpieces

Here's another idea. I think BOSE already made it, but I don't know how theirs work. My idea though is simple. We simply have a earpiece that takes in sound from the current environment, and reverses it, and play it back into the earpiece. Then because the two sounds will cancel out, we will hear nothing.

Identity Phones

Mobile phones that use fingerprint and retina scan to verify our identity. They can therefore contain our credit card info, our bank account info...even the "cash" we have withdrawn from our bank into our phones...and info for all the various cards we carry...train passes, office passes, discount vouchers, etc.

So all we have to do is scan the info into our phones, and if we need to make a purchase or use the info which is secure, just place our fingerprint and retina scan for access and then the money or info is accessed accordingly by the relevant external devices...

No need to walk around with big fat wallets!

iTable

Picture this, a table with the desk surface as a touch screen monitor so you can write on it with a stylus, or use your hands and fingers to "move" paper. Moreover, have the desk hot-wired so that the CPU is integrated into the drawers. Have the port built into the table too. You can have a USB port on the table, a phone or ethernet port for physical network connectivity, a built in wireless. Have all the cables fabricated into one cable, so that the user just needs to plug-in one cable for power and/or for networking.

Cool looking.

Visor Monitor

Instead of using monitors, we can use visors and monitors. This would increase the field of view with the screen being the whole visor. You can make it into a 3D interface so active windows or documents and applications are ordered in terms of depth layers. You can also detect the user's head position and move the screen in a 3D world accordingly. You can even include earphones connected to the visor. Just connect an LCD visor with a DVI or VGA cable to the CPU, with the approriate driver and softwares of course!

Sonic Boom Horn

Sometimes, people can't react in time to oncoming traffic, or they just don't notice. By the time they know how to react, it might be too late. So why not let the honk of an oncoming vehicle do more than warn? Why not enable it to actually push people away?

The sonic boom horn is a device which blasts a wave of sound that both warns people as well as pushes them away. This is because the sonic energy blast is creates a pocket of air pressure that is strong enough to displace bodies that might be in its path.

BOOM!!

Domed City

Dome an entire city in glass or plexiglass.

This would offer the advantage of climate control and protection. Imagine, having cool air when the external air is too hot or vice versa. You could also protect against typhoons and storms and UV light exposure.

The dome structure itself can be used as scaffolding for buildings, train tracks. In other words, your city could go up instead of sideways.

I'd live in that city!
