RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

What do vintage grain mills, your lawn sprinkler,
and Hoover Dam have in common with Ecodigital's new
H20 FM radio? They all run on water power. According to their
website, the H2O is the world's first water pressure powered shower radio. It is
installed inline between the shower supply pipe and the shower head. The water flow
powers a patented, integrated turbine generator which creates energy to power the
radio. The H2O Shower Power Radio is a patented innovative product which uses the
latest technology of miniature water turbines to create energy. A built-in rechargeable
battery allows you to take the radio with you for listening elsewhere - maybe in
a good rain downpour!
