Darpa recently issued a request for information about supplying “persistent broadband ground connectivity for spacecraft in low-Earth orbit.” The idea would be to give these satellites a near-constant feed of “100 kbps or higher” two-way connectivity, with end-to-end transmission latency of less than a second.
…part of this is trying to bring those internet concepts of automatic routing and network config to satellite constellations, and perhaps to make them extensions of the land-based internet infrastructure.”

Darpa Looks To Send The Internet Into Orbit
“
First lofted into orbit in the 1970s, the FLTSATCOM bird was at the time a major advance in military communications. Their 23 channels were used by every branch of the U.S. armed forces and the White House for encrypted data and voice, typically from portable ground units that could be quickly unpacked and put to use on the battlefield.
As the original FLTSAT constellation of four satellites fell out of service, the Navy launched a more advanced UFO satellite (for Ultra High Frequency Follow-On) to replace them. Today, there are two FLTSAT and eight UFO birds in geosynchronous orbit. Navy contractors are working on a next-generation system called Mobile User Objective System beginning in September 2009.
Until then, the military is still using aging FLTSAT and UFO satellites — and so are a lot of Brazilians. While the technology on the transponders still dates from the 1970s, radio sets back on Earth have only improved and plummeted in cost — opening a cheap, efficient and illegal backdoor.
To use the satellite, pirates typically take an ordinary ham radio transmitter, which operates in the 144- to 148-MHZ range, and add a frequency doubler cobbled from coils and a varactor diode. That lets the radio stretch into the lower end of FLTSATCOM’s 292- to 317-MHz uplink range. All the gear can be bought near any truck stop for less than $500. Ads on specialized websites offer to perform the conversion for less than $100. Taught the ropes, even rough electricians can make Bolinha-ware.
“I saw it more than once in truck repair shops,” says amateur radio operator Adinei Brochi (PY2ADN) “Nearly illiterate men rigged a radio in less than one minute, rolling wire on a coil.”

Toyota has created two flower species that absorb nitrogen oxides and take heat out of the atmosphere.
The flowers, derivatives of the cherry sage plant and the gardenia, were specially developed for the grounds of Toyota’s Prius plant in Toyota City, Japan.
The sage derivative’s leaves have unique characteristics that absorb harmful gases, while the gardenia’s leaves create water vapour in the air, reducing the surface temperature of the factory surrounds and, therefore, reducing the energy needed for cooling, in turn producing less carbon dioxide (CO2).

Many Kabuli residents looking for new mobile phone ringtones, wallpapers and applications to spice up their mobile phone turn to their neighbourhood content kiosk - all that is needed to set up as a vendor is a PC; access to power; a DVD starter pack of pirated content and walk-by trade. Whilst the market today is dominated by stand-alone specialists this will change.
Expect to see three disruptions in this space: the prevalence of cheap net books will lower the cost of entry and enabled vendors without constant access to mains power and/or a backup generator to set up shop - currently most content sits on desktop PC’s, the mobility offered by net books make it feasible to perch a unit to the side of a shop counter and gives the vendor something to do (playing games) whilst waiting for the next customer; the global move towards Micro-USB for charging mobile phones will also lower the barriers to transfer data - currently there are numerous methods to move data from PC to mobile phone and the consumer experience is highly variable - a standardised service makes it more of a viable proposition, and the net book is also able to function as a charging hub, and whilst not ideal it enables drop-off/ transfer/pick-up type behaviours; a shorter distance to the nearest internet connected hub to download/obtain recent content for resale.
