Re: [hreg] Solar lawn care
- Actually, I've got solar beat for lawn care--at least for mowing. It's
pretty simple, too. I just use an old-fashioned push mower. It takes about
as much effort to push as a much heavier gas mower, it's very safe (I mow in
shorts and sandals without worry) and it's so quiet that I've taken calls on
my cellphone while mowing.
I'd highly recommend one for anyone who is opposed to using gas mowers,
wants a little exercise, and has a small-to-medium sized yard.

I am with you all on solar powered lawn care. I use a pushmower (no gas or
electric), but do the trimming and edging, via an electric weed eater, with
power from my battery bank in my garage.
Though we do not have an air quality probelem (yet!) in Port Townsend,
Washington, there is something to be said about noise pollution and fuel
220 Amp-hour Battery Bank at 24 V (n=4 Trojan T-105)
64 Watt PV Panel (Evergreen)
C-25 Charge Controller (Trace)
DR 3624 Inverter (Trace)
I use the system mainly to charge my 10 Amp-hour electric bike battery
through an AC charger acquired with the bike. I had charged the bike
directly with DC for over a year, but I could not charge when I got home late
in the day.
We lose power perhaps 2 to 3 times per year, for an average of 8 to 24 hours
each. So, I will also be able to fix a pot of coffee.
If we were still in Houston, alternative powered lawn care would be a cause I
would support vigorously. Good job folks and good luck.

- A buddy of mine in Houston had a company for a while called : "Clean Air
Lawn Care". Their logo was of a blower with a circle around it and a slash
They maintained lawns with such archaic devices as the reel mower, manual
edger, shears, rakes, and brooms.
