Powercast looking to
bring wireless power to
reality
We know, energy without wires has always
seemed like
one of those
novel concepts that sounds terrific in theory, but remains a tad difficult
to imagine hitting the commercial scene
for some time to come.
Apparently, all that is about
to become nonsense, as a
Pennsylvania-based startup is set to capture the wireless-loving hearts of,
um, everyone when it tacklescontactless power products. Powercast has
already "signed nondisclosure agreements to develop products with
more than 100 companies (Philips, for instance), including major
manufacturers of cellphones, MP3 players, automotive parts,
temperature sensors, hearing aids,
and medical implants." The firm's
radio-wave-receiving
miracle device trumps existing attempts by
"adjusting to variations in load
and field
strength while maintaining a
constant DC voltage," essentially ensuring that only low wattages (read:
the stuff that garners FCC
admiration) are flung around. The system
basically consists of two parts
-- a wall-plug transmitter and a
"dime-sized receiver" that handles the real magic -- and energy is instantly transmitted whenever that disc comes within a yard or so of its
tag-team partner. Incredibly, the receiver only costs "about $5"
to
produce, yet the outfit has already secured upwards of $10 million
in
private funding, which translates into one less American that desperately
needs to win the lottery. Get ready folks, if all goes well, Powercast will be
shipping "many millions of units" by the end of 2008 -- and maybe even
sooner.
大家对于那堆理论、计划但却没有实际的行动感到厌倦了吗?这个让不少人盼了又盼,等了又等的技术,看来真要有见天日的一天啰!
美国宾州的一家公司,目前靠着这个 Powercast 技术,已经和超过百家的主要电子产品公司,签下内容尚未公开的合作案,包括一些耗电量 "相对较低" 的电子产品,诸如手机、MP3
随身听,还有汽车零件、温度感应器、助听器,甚至是医疗仪器等的制造业者。
基本上整个系统包含了两件东西,一个是插在插座上的发信器,另一个电子产品上,跟硬币大小差不多的接收器(技术核心),只要在一定的范围内(目前是在 90 公分的距离内),电源能够瞬间自发信器传到对应的接受器。
该项技术之所以会得到这么多家厂商的青睐,原因是在他独特的无线电波接收装置,能够根据不同的负载、电场强度来作调整,同时还能维持稳定的直流电压,这也表示在空中乱喷的电磁波功率,能够被减到最低。(据说这玩意已经获得了 FCC 的认可)
最神奇的是,这接收器的制造成本,竟然只要 5 块钱美金;目前预计将在 2008 年底,也许会更快,就会出现在部份的电子产品上头了。另外各位常常在外奔波的笔电使用者,也不用心急,等到各位的笔电/UMPC 耗电量降到了个位数(目前的极限),你将来在外头上网,应该是不需要带充电器了,不过以后网络费可能要跟电费绑在一起就是。(按:这一切并不是愚人节的玩笑!)
