A standard 3rd party iphone/ipod USB cable will run you less than $5, at which point any standard USB power source will charge your iDevice. Where are you getting $30 from? Plus, how many manufacturers have used the same physical connector on virtually all their devices for over 9 years? It's not like they're making you go out and buy a new cable/charger every 2-3 years.
If you're just trying to get it hovering indoors a few feet off the ground, there's really a pretty narrow RPM band you need to be concerned with. Why introduce the added drivetrain loss (however small) and weight of extra gears?
According to the teams website, they think the extra hand pedaling increases the amount of power the human pilot can put out around 10-20%. Sounds worth it.
As to the recumbent position, I'm just guessing but maybe it has to do with stresses on the frame (which looks like it's barely up to the task of supporting the pilot). On upright bikes riders often have a tendency to mash the peddles, rather than smoothly spinning them, creating highly directional and varying forces. A recumbent position limits the amount of force you can apply to a single peddle.
I think for my first Android software project I'm going to come up with a text message like program that uses your data plan. I could make a killing on something like that if it took off. Although I'll probably get my ass sued off by patent trolls so I may not bother.
Right after you build your time machine to go back in time 4 years before the 100+ other people already made apps that do just that for Android / iOS.
Good book. If I recall, those blackholes were also created in an accelerator built on a remote asteroid a safe distance from Earth. Maybe we should listen to him.
When the iPhone was release, the iPhone contracts with AT&T were cheaper than their other smartphone (voice & data) contracts by about $10-15/month. That translates into something like $250+ over the course of a 2 year agreement, which is about the same as the $200 higher price for the iPhone compared to the subsidized smartphones available from AT&T.
It may not have been explicitly stated, but coupled with the fact that you didn't have to sign a contract to walk out with the phone, it pretty much adds up to it not being subsidized.
The question is, can you walk into the store and get an iPhone for this price, without having to sign a 2 year contract.
The reason the iPhone originally cost so much more than we're used to seeing phones cost, is because it was not subsidized by a 2 year service contract.
Now that they've lowered the price, can I still walk into the Apple store and buy a new iPhone and walk out without signing a contract.
The point that might not be being explained properly, is the whole Conservation of Energy (and also Mass) thing. The only way virtual particles can be produced from the vacuum is if they recombine and disapear before the violation of the Conservation of Energy can be measured. Otherwise you'd be getting something for nothing. In this case, the particles are being separated from each other before they can recombine, and it doesn't matter whether a particle or anti-particle falls into the black hole. For its virtual partner to be able to survive while obeying the laws of conservation, the particle falling into the black hole must subtract mass/energy from the black hole. Remember, all matter, whether matter or anti-matter, has POSITIVE mass/energy, it's just their other properties that are opposite. In this case we're talking about matter that in some ways appears to have NEGATIVE mass/energy. And that is what is decreasing the mass/energy of the black hole.
Everything I've read about the reflectors left on the moon describes them as the corner-cube type of reflectors, although looking at a close up picture it's hard to tell if the mirrors are cubes or spheres.
Except you're missing one of the differences between geostationary and low earth orbits. While the geostat satelites are all out there moving pretty much in sync with each other in one equtorial ring, LEO sats are buzzing around criss-crossing each other's paths all the time. So the ISS and Shuttle, and anything else at the altitude of LEO, can and does get hit.
My 80mw laser made my thermometer jump from 70F to 163F in about 2 seconds before displaying LLLF. I don't know what temperature LLL really represents, but I bet it's hot.
Orbital lag is really just a problem with sats in geosync orbit. A network of low-earth orbiting satelites would be able to give you ping times as low as most landlines.
The Moon is already slowing down the Earth's rotation at a far higher rate than this elevator ever would. In a few million years the Earth will be tidal locked with the Moon just as it is already locked with the Earth, except at that point it will be a bit farther away than it is from us now.
That's pretty cool. I tried finding software to do this a few months ago when I realized I had 2 identical webcams sitting on a shelf not doing anything, but with no luck.
Is it available for download or only commercially?
If only everyone named Gates could create a web server that could take a slashdotting.

Or just build an arrester cable near the bottom and put something on the sled to hook onto the rope like some of us Discovery channel watching kids did.

must you humans be so dense?
Good, I'm not the only one who read that the first time.
Spheres and partial cubes are both ways to construct retroreflectors: http://en.wikipedia.org/wiki/Retroreflector

Actually, no.
200% more + 100% original = 300% total = 3x the power.
Well he is a man who loves his taffy.

Pi is exactly 3!
Excellent, and once we have those devices in place we'll just need some kind of device that can trigger earthquakes on demand....
Oh wait, that wouldn't get us free energy, just another bad movie.

No way! They went straight from IV to VI.
Sounds like the marketing people at Netscape used to work for Paramount too.
I've been trying to get my hands on one of Xenarc's 7" 800x480 LCD screens for awhile now.
It seems that Xenarc can't/won't produce them nearly fast enough to keep up with demand and so resellers are always out of stock.
