Hornet wind turbine? [RE-wrenches]

[Allan Sindelar]

Here are a few selected lines copied from that web site. I think they speak
for themselves:

a.. 4000 RPM at 12.5 volts input
a.. 12 volt input voltage max.
a.. Sold as is - No warranty (All units are tested before shipping)

Hint: Try calling places that sell used fork lifts. The 12 volt batteries
that run fork lifts are the best! Many of these old batteries are discarded
becuase they can no longer operate a fork lift for a full 8 hour work day
but they still have enough operational life to run your household for many
decades. Many can be bought at recycling prices and still have 100 times
more amperage than a brand new bank of automotive batteries. (Note: They are
VERY heavy)

1. True sinewave inverters waste considerable battery energy due to their
voracious appetite for idle current (typically 120 Amp/hours per day) and
poor conversion efficiency (85% typically). These unacceptable losses must
be made up necessitating 2-3 more generator hours per day than you would
experience with our brand MSW inverter under identical usage!
2. Many motors that will start and run properly with a MSW inverter may fail
to start or run properly when powered with a true sinewave inverter due to
much lower surge and power factor capability.
3. True sinewave inverters are physically much larger than MSW inverters.
4. True sinewave inverters have considerably more components operating at
higher speeds and stress levels resulting in greatly reduced reliability.
5. A typical true sinewave inverter costs up to 4 times more than a MSW
inverter does!

Idle current is the power consumed from your battery to run the inverter
internal electronics. Since this current does not power your load, it is
wasted power. Typical 5000 Watt true sinewave inverter draws about 5 Amps of
idle current, an unacceptable loss that will require about 3 generator hours
per day to make up. (5 Amps x 24 = 240 Amp/hours per day.)

It is interesting to note that the Idle Current specification has been
conveniently omitted on every true sinewave inverter data sheet we have
seen!

SMART IDEAS: Since all inventors give off some heat it is a good idea to
mount them indoors so you can us this residual heat to warm up your home if
you live in cooler climate areas.
Surprisingly, many inverters (both sinewave and MSW) do not accommodate
bi-directional power flow. This is clearly an egregious design faux pas that
seriously limits the types of loads they can run.

The MSW inverter uses a direct 60 Hertz waveform synthesis that properly
allows bi-directional power flow. This is one of the many reasons that our
MSW inverters run loads that fail to run on many competing true sinewave
inverters!

'Nuff said?
