We were promised Jet Packs (v2.0)

Awesome!
I want more info. Flight time, maximum speed, height, distance. They imply at least a 5 min flight time, but I want to see the real specs.

Would Headlights Work at Light Speed?
How about -sometimes photons appear to have mass, sometimes they don't.
As for Neutrinos, apparently they also can't exceed the speed of light. The experiment that said they might was flawed.

Umm... photons have mass.
Why is he saying they don't have mass?
Neutrinos also travel at or faster than the speed of light and have mass.

Sue Austin: Deep sea diving ... in a wheelchair
Strange? problematic? Wasn't Jacques Cousteau using stuff like this: http://www.gizmag.com/go/7148/ back in the 1970s? Her arms work so she could use something like this quite effectively right?
Carrot Sharpener, and other really, really useful objects!

Biker inches away from being hit
This was Gizmag's Loz Blain testing the bike for a review. Youtube link here - http://www.youtube.com/watch?v=9TxEw1LunfM which has a link to the article.
I still don't know where it was. It looks like Australia/NZ, but why is he talking mph and inches?
Bike Lane in NYC
Now here is an interesting idea. This device is mounted to the handlebars of a bike and projects a bright green image onto the roadway in front of the bike. It's designed to warn autos of the oncoming bike.

Infinitely Variable Geared Transmission

^ they go through an engineering report on the device. key points being the "control" motor would have to be as powerful as the "drive" motor (in terms of torque), and control motor would also need it's own CVT, which introduces a friction component into the system.
Infinitely Variable Geared Transmission
very cool and interesting invention.
here's article that goes with that video http://www.gizmag.com/steve-durnin-ddrive-d-drive-infinitely-variable-transmission-geared/15088/
The Political Future of Nuclear Fusion
interesting, but i'm very skeptical of the timeframes given... not to mention the hypothetical building costs for this hypothetical commercial energy production
as an example of this, here's a recent time magazine article on the "comeback" of nuclear power plants:
http://www.time.com/time/magazine/article/0,9171,1869203,00.html
just look at those cost overruns and timeframes for a *known* and now-politically acceptable method of energy production -- now we just need to get over our fears of safely transporting our nuclear waste by inter-state rail to the massive yucca mountain repository
all that aside, i really hope that we don't put all our eggs in one basket - there's certainly no dearth of promising energy alternatives
imho, this man is brilliant - please take the time to consider this testimonial

anyway, good sift... thanks
