Electricity on the farm

It's almost March! For some people in North America, spring has already begun, and they are hard at work preparing garden beds. It's -25 C here, and there is no garden work to be done.
I am instead working on keeping our pipes unfrozen, and our electricity on.
A few days ago, my awesome Wacker-Neuson generator had some major problems, making it necessary to buy a second generator, just a cheap Champion 3500 watt used one. My Wacker (what a name...) genny is actually running now, and I suspect that the cold weather is keeping it going. Some electrical part kept cutting out when it was warm last week, so I will certainly need to find that and fix it. Now, the new generator was running poorly last night, and I found the problem...a giant chunk of ice in the intake. There is still a bunch of ice in the air intake, so I will need some cleaning on that one.
For those of you who may be considering an off-grid system, and maybe like me you rely on a generator until you can afford solar panels, here is some advice. Two working generators at all times. Having your only generator cut out is NOT acceptable, a backup is a MUST! Even a cheap one bought used is fine, as long as you don't store it with gas in the tank, and run it for an hour every two months.
I had some other electricity related thoughts: I found something on the internet at this site
www.greensteamengine.com and I was astounded at the potential. These boys have invented a steam engine that can run off a pressure canner, is about the same size as a regular generator, probably 1/3 the weight, and produces no exhaust gas (the steam can be recondensed and used again). It can operate off of pressures up to 50 psi, or as low as 10. You can attach a small generator directly to the driveshaft, and tie it into your batteries.
For me, I picture using this in the winter, putting the pressure boiler directly on top of my wood stove! Even if it only produces 2000 watts, on dark cloudy days, it would easily produce all our electricity with ease in just a few hours. It would not be needed in summer, when the days are much longer, and the solar panels could take up the slack.
I tried to contact the website about prices, still haven't got a reply.
I will post any replies I get, in case anyone else finds this kind of interesting.
Adios for now!
