Hi ashtweth,

Wasn?t the RV lawnmower considered to be a hoax?

hi  argona, No i find Brian Prater to be Creditable, And the spooks only usually turn up when you have some thing working

   Kone also did an RV lawn mower.

"Doug Conzen has been the first to benefit by applying the RV energy saving principle into real life applications, which saved him energy and money. Doug likes to cut grass  and did so with this adaptation of a home depot lawn mower. This test clearly demonstrates the significant energy saving involved with the RV?s capacity of power on demand, and how the use of this technology in intermittent roles works in making the energy consumption drop.

Quote: Today I cut some grass with the RV lawnmower - it cut through it great, and it was wet and high grass too. The amps went DOWN when cutting grass - started out at 1.4Aac and dropped to 1.2A while cutting. These Electric lawn mowers you can buy in stores like home depot and draw 15Amps so that is pretty good doing it RV instead at around 1.2A.One thing I did is made my own aluminium-blade in it, this saves lots of watts as compared to the original heavy thick steel one.

1.2 A is 12.5 times less energy than the 15 amp HD ones

I Just spent around 3 hrs mowing a couple lawns with the red RV mower it bogged down in thick grass and I had to restart it a few times, but so does the gas mower too in same place. Anyways I used 19uf run cap, and 5uf more for start cap, for a time in the thick grass, I hooked up the start cap all the time and then the motor got hot a bit but not too hot. It would be nice to have a switch for easy adjusting of the cap-uf
size, as at pure-idle mode, I could drop that run cap down to 10uf or even lower, but then when you hit the grass with it, there isn?t enough power to cut it without bogging down so you need a "load" cap as well as an "idle" and "start" cap too is what I would say for next lawn mowing job.

Also I ran the mower on a single half-charged up 7ah/12V battery not a Coleman 400W invertor and then the invertor running the RV lawn mower. The speed and power seemed the same as when running direct 120VAC house power (with long cord) but the battery drained down pretty fast - I didn?t look at the current-draw (didn?t have meter that big) but assume it is around 12A X 12VDC as its 144W watts on 120VAC.

This lawn mower is a good demonstrator for sure - its very easy actually to do the conversion, my motor is only 1/2hp too, lots of them on e-bay for super cheap I  would go up to 1hp rated AC motor next lawnmower project however.

One thing I did is made my own aluminium-blade in it, this saves lots of watts as compared to the original heavy thick steel one - you don?t need all that blade to cut  grass. In conclusion I?m using only 1.2A ac compare to "conventional mower" using  15 isn?t a direct-comparison, since I changed the blade too maybe if the conventional  electric lawnmower had a lightweight blade, it would then only draw 8 or 9 amps
I would guess. ?end quote"

Kone is on EVGRAY yahoo energy groups, he just posted a new RV/DC pule motor design, am working my way up to adding into the compilaitons
