			<content:encoded><![CDATA[<p>The Pi electric bicycle uses a semi-automatic 8-speed transmission to downshift into a lower gear for climbing hills, then up shift for rapid acceleration to a maximum of 20 mph on flats and allows you to pedal normally because the motor automatically disengages when not in use. Powered by a 750-watt electric motor housed in the horizontal chain and motor assembly, the Pi electric bicycle is capable of three modes of operation: electric motor power, human power, or the human-electric hybrid power combination. The electric motor and rider utilize the same 8 speed semi-automatic transmission making rapid acceleration from a stop or lower gears available for steep inclines possible (but with slower acceleration.</p>
<p style="text-align: center"><img src="http://imagesme.net/tuvie/electric-pi-bike1.jpg" alt="electric pi bike" /></p>
<p><span id="more-568"></span><br />
The motor automatically disengages from the pedals when desired so as to preserve battery life. Construction begins with a 12’ foot straight piece of 3⁄8-gauge, aircraft aluminum 6061 alloy that is roll-formed and annealed for uniform wall thickness into a complete 6&#8242; diameter circular tube with a 4&#8243; exterior diameter (the NiMH batteries reside within the tube from the front fork to the seat), which is then bisected to make a 6&#8242; long arc for the bicycle’s frame. The sturdy frame supports riders up to 300 lbs.</p>
<p>The top of the arc provides a 26&#8243; stand over height, allowing you to place both feet on the ground. The padded ergonomic gel seat provides for comfortable, relaxed riding. It attaches to the frame via a gas strut assembly that raises and lowers like a pneumatic office chair, accommodating riders between 5-7&#8242; tall in a semi-recumbent position for ideal pedaling or powered coasting. A dynamo in the front wheel’s hub provides power for auxiliary lighting.</p>
<p style="text-align: center"><img src="http://imagesme.net/tuvie/electric-pi-bike2.jpg" alt="electric pi bike" /></p>
<p>The bicycle has a range of up to 30 miles at 20 mph before requiring a five-hour re-charge from its AC adapter. Precisely tuned hydraulic disc brakes provide sure stops, and the wheels are made of dual-walled aluminum alloy and stainless-steel spokes; the 26&#8243; semi-slick tires are ideal for roads or paved trails and use Presta valves. The bicycle is wet-painted in Rossa Corsa red using the same PPG color specification as high performance sports cars and treated with a clear coat finish for a luster that will last.</p>

			<content:encoded><![CDATA[<p>SkyTran is a concept for high-capacity and high-speed personal rapid transport developed by an American Company UniModal Transport Solutions. This SkyTran system is two-passenger vehicles, propelled and suspended by maglev system. These are laid out in a one mile by one mile networked grid throughout the city. A large number of small departure and exit portals are placed underneath the guideways at approximately every 400 metres or at every city block.</p>
<p style="text-align: center"><img src="http://imagesme.net/tuvie/sky-tran-maglev-system1.jpg" alt="skytran with maglev system" /></p>
<p style="text-align: center"><img src="http://imagesme.net/tuvie/sky-tran-maglev-system2.jpg" alt="future skytran with maglev system" /></p>
<p style="text-align: center"><img src="http://imagesme.net/tuvie/sky-tran-maglev-system3.jpg" alt="futuristic transportation with maglev system" /></p>
<p>SkyTran has no fixed routes or timetables. Users can simply enter any departure portal, get into the first empty vehicle in the queue and select their destination. The vehicle then speeds up on the acceleration lane and enters the high-speed overhead guideway.</p>

<p>Great concept, this will definitely reduce traffic jam, but with only two passengers for each pod, what about families ? Using SkyTran they have to sit separately. Hopefully UniModal will come up with new model or updated version of the SkyTran pods.</p>
