TrentonMakes Posted March 12, 2018 Share #1 Posted March 12, 2018 While bailing water out of the house's two sumps Thursday night I was looking at my old Panasonic bike, and the mag trainer, and wondering what I would have to do in order to MacGyver some way to pedal a bicycle and generate enough electricity to run the pump for a little bit. After UTFG it looks like I'd need an electric motor, battery, AC inverter, and a few other bits (and probably a wheel dedicated to this purpose). Surely someone here has done this...

Longjohn ★ Posted March 12, 2018 Share #2 Posted March 12, 2018 Someone posted a picture and I think a link to a trainer that generates electric. I would guess you could make enough to run a pump. They posted it during this recent power outage but I don't remember which thread. 1 Link to comment Share on other sites More sharing options...

Razors Edge ★ Posted March 12, 2018 Share #6 Posted March 12, 2018 Could you go mechanical rather than electrical? Seems like pumps of different sorts have been around for centuries? Honestly, though, maybe just the cheapest Honda generator would be more versatile and far simpler. Tom 1 Link to comment Share on other sites More sharing options...

There is a lot of power lost in going through a generator to an electric motor to a pump. Something else, electric motor operated pumps are likely to be 'non-positive' displacement type pumps. More losses, especially against head pressure. Link to comment Share on other sites More sharing options...

jsharr ★ Posted March 12, 2018 Share #9 Posted March 12, 2018 You are overthinking this. Go direct, drive the waterpump with the bike and skip all the electric crap 1 1 Link to comment Share on other sites More sharing options...

That was my first thought too, but based on Google returns it seems most people are attacking this problem the other way. Or more likely, most people are more concerned about generating electricity to power multiple devices. A mechanical sump pump is a one-trick pony that won't charge a phone. It is probably a 'blessing in disguise' that the basement took on water even while we are finalizing the agreement with a contractor to finish half of it. I will make damn sure to include redundant systems to keep it dry. Simply elevating everything - on tables, or to the garage - won't be enough anymore.

Kzoo Posted March 12, 2018 Share #12 Posted March 12, 2018 Or you could just make some ice cream while you wait for the sump pump to finish. @Digital_photog to the ice cream bicycle phone. 2 1 Link to comment Share on other sites More sharing options...

Page Turner Posted March 12, 2018 Share #14 Posted March 12, 2018 ...in the fire department, we just used a portable pump unit with a built in IC engine. They work great, too. 429 bucks with free shipping. Make sure to install a fuel shutoff if it doesn't have one, and run the gas out of the carb between uses. https://www.waterpumpsdirect.com/Honda-WB20-Water-Pump/p6302.html?gclid=CjwKCAjwypjVBRANEiwAJAxlIpAMZhtRmJLuqEBFm98VqMI2rJyLygbCYpt0xsUNVleMoPH9gUSgRRoCg_sQAvD_BwE 1 Link to comment Share on other sites More sharing options...
12string Posted March 12, 2018 Share #15 Posted March 12, 2018 You are just thinking all wrong about this. If you head to the basement for a workout and find the bike underwater, switch your workout to swimming. Why must you all complicate life? 1 1 Link to comment Share on other sites More sharing options...

No, that was the pedal powered scuba pump. He will need to make one of those after his pedal powered water pump fails and his basement floods. They also had a pedal powered washing machine. Maybe he can make one of those to go with his pedal powered water pump. They also had the pedal powered radio transmitter. 1 Link to comment Share on other sites More sharing options...
