You know what communicated the perils of Net Brutality to me? Images like this one:
http://www.ohgizmo.com/2009/10/29/net-neutrality-what-it-could-mean/
Websites being reduced to cable-like add ons. Just terrible.
Edit: I followed the chain of blog spam attribution all the way back to the original source of the Net Neutrality graphic:

Edit2: Another similar example:

Apparently this was a big deal in 2009.

I got my dad an ultracapacitor flashlight (http://www.ohgizmo.com/2008/11/10/ultracapacitor-flashlight-recharges-… a few years back and he loved it till it got stolen. Really quick recharge time, decent "battery" life.
Interestingly this flashlight was discontinued, and I don't see any new ones on 5.11 tactical's website. I wonder why?
I'm really interested in any increases in these types of technology, love to see what comes of this.

Thanks for the links. Your comments about the "OLDEST HUMAN VOICE RECORDING OF ALL TIME" reminded me about a thought experiment I once heard.
Imagine a pottery wheel spinning thousands of years ago, and people talking as it spun. Then imagine that for some reason, a stick or other object was leaning against the wheel, and engraving a pattern. Theoretically, the vibrations of the people speaking would be picked up (at some level) by this engraving.
The end result is that if you had a device that was sufficiently sensitive, and you could remove a sufficiently large amount of noise (caused by other sources of vibration), then you could reconstruct an actual recording of people speaking thousands of years ago.
Of course, it is not likely that this will happen in the near future, or even at all. In fact, a quick search will show that it has already been used as an April Fools joke by some scientists [0].
However, that is not to say that it is impossible.
The reason I love this thought experiment is because it goes to show that if you start with the presumption that at some point, our tools become better, then there are very few limits to what can be found out. What would happen if you went back 150 years and told everybody that in 150 years, we would have tools that can track the trajectories of sub-atomic particles as they travel at speeds horrendously close to the speed of light?

The Senseboard virtual keyboard tried to do that a decade ago: https://sandipsandilya.wordpress.com/2010/07/21/senseboard-virtual-key… and the AirType as well a bit more recently https://www.ohgizmo.com/airtype-keyless-keyboard-future/

Never seen Space Patrol, so missed that, but I liked the references to the Amiga, C64 and the game Impossible Mission... http://www.ohgizmo.com/wp-content/uploads/2008/09/impossible_mission_2…

The commercial WiFi power harvester I remembered would be the perfect partner for a WiFi Spy.
Despite the announcement that "on the CES floor, they were able to charge a BlackBerry from 30% to full in about 90 minutes, using nothing but ambient WiFi signals as a power source. " [1]
The device has never been turned into a commercial product. [2]

Totally! Of course, if it didn't need to be plugged in, a la Airnergy[1]^, and if it used wifi... and maybe if it were weatherized, then it would never need to be indoors in the first place. As long as it was never delivered to a place without wireless, it would be "alive."
Arranging its own transportation via FedEx would incorporate the printing method you describe, and it could pretty much move on its own.

in japan they have a robot to bring you beer.
http://www.ohgizmo.com/2006/01/26/asahis-beer-pouring-robots/
so everything is complete. job accomplished, now if only we had all of the things they predicted in the 80's that would be around by 2020, like robo-cop, and hoverboards.
