Prototype Nokia phone recharges without wires
Pardon the cliche, but it's one of the holiest of Holy Grails of technology: Wireless power. And while early lab experiments have
been able to "beam" electricity a few feet to power a light bulb, the
day when our laptops and cell phones can charge without having to plug
them in to a wall socket still seems decades in the future.

Nokia, however, has taken another baby step in that direction with
the invention of a cell phone that recharges itself using a unique
system: It harvests ambient radio waves from the air, and turns that
energy into usable power. Enough, at least, to keep a cell phone from
running out of juice.
While "traditional" (if there is such a
thing) wireless power systems are specifically designed with a
transmitter and receiver in mind, Nokia's system isn't finicky about
where it gets its wireless waves. TV, radio, other mobile phone systems
-- all of this stuff just bounces around the air and most of it is
wasted, absorbed into the environment or scattered into the ether.
Nokia picks up all the bits and pieces of these waves and uses the
collected electromagnetic energy to create electrical current, then
uses that to recharge the phone's battery. A huge range of frequencies
can be utilized by the system (there's no other way, really, as the
energy in any given wave is infinitesimal). It's the same idea that
Tesla was exploring 100 years ago, just on a tiny scale.
Mind
you, harvesting ambient electromagnetic energy is never going to offer
enough electricity to power your whole house or office, but it just
might be enough to keep a cell phone alive and kicking. Currently Nokia
is able to harvest all of 5 milliwatts from the air; the goal is to
increase that to 20 milliwatts in the short term and 50 milliwatts down
the line. That wouldn't be enough to keep the phone alive during an
active call, but would be enough to slowly recharge the cell phone
battery while it's in standby mode, theoretically offering infinite
power -- provided you're not stuck deep underground where radio waves
can't penetrate.
Nokia says it hopes to commercialize the technology in three to five years.
Morning walk with Guru Maharaj
Today I got up in the morning to attend mangala arti by the extreme mercy of Sri Sri Radha Parthasarathi ji.....After that i was chanting jap but it was too hot for me in the temple hall to stand....so i was chanting outside.....at around 6.15 am, i saw GM going towards the place where we wash our hands after taking carnamrta...seeing this i also moved towards GM. He was asking some devotee if it would be better to go for walk right now or later at 8 am...he asked me also & i suggested that its better to got right now as the sun may come up & i will be very hot then....He agreed....
Then we went to the naturopathy for walk where GM does his morning walk. But as the girls there were sweeping the whole place over , i told GM not to walk here as it is not good for his sinus...He agreed & we both walked towards the C block market & then to the RHS in Kailash colony..We came across a place which looked like a garden...GM told me to run & see what it is....it was indeed a park but a neglected one.....Still GM entered it.....It was big & but not so nicely maintained...GM liked the place & he told," See Niranjana, we have discovered a new place for walking" i can come here in car & then do my walking here, the only problem is its very uneven being a hilly area." We kept walking & we took a non cemented road back to the temple behind the lotus temple...finally we arrived back at temple & then GM allowed me to take off his socks....I did so for the first time.....Looks very simple but when you have to do it for GM, you know how much nervous you can become...thinking would i do it the right way or not...
I felt really good after attending the morning program and specially the association with GM....I feel hope & a little bit of determination too, that my spiritual life can improve, if i keep getting this association in future..I feel like a small kid who needs protection & when GM is there I feel protected. I feel happy ...& all the problems doesnt disturb my mind....Hare krishna
