Use Your Bike as a Backup to Your Backup Power Supply

I&#x27;ve been watching the <i>Long Way Up</i> motorcycle travelogue series with Ewan McGregor and Charlie Borman on AppleTV+.<p>They&#x27;re doing the trip from the tip of South America all the way to Los Angeles on a pair of prototype electric Harley Davidsons. The support crew is in a pair of prototype Rivian pickup trucks.<p>The Rivians have a &quot;tow to recharge&quot; mode that they&#x27;ve used several times already in the first half dozen episodes.<p>The show is great and I&#x27;m as fascinated by their dedication to do the trip on electric bikes (the first parts of the trip were in freezing and sub-freezing temps in areas with long distances between grid electricity availability) as I am by the scenery and their narration.<p>Anyway, sorry for the tangent, but the title reminded me of the series. I hope it escapes AppleTV+ so that non-Apple folks can watch it at some point.

I&#x27;ve actually considered this many times, but the math never works out. I ride 50KM 3 times a week, Strava&#x27;s &quot;estimated power rating&quot; is all over the place, given i ride the same trail every time i would think it should not be like this.<p>Lets be reasonable and say 160W (somewhere between all the ratings strava gave) avg for my 2 hour trip.<p>I think I am a pretty strong rider, at the peak of the season I can beat electric bikes on flat ground as my top speed is higher then theirs (I dont have a speed limiter, they do)<p>I can tell you this is NOT easy and once you realize how much physical effort it is you appreciate being able to plug things into the wall.<p>it is the sustained power output that will kill you.. You can probably dump 10w of power for a long time, but putting out serious power for extended periods of time isnt easy.

When rowing I can throw down a significantly larger amount of power than when I&#x27;m cycling (almost a kilowatt in a short sprint), but ultimately my average sustainable power in both sports is about between 150w-250w. This article got me thinking about calculating the amount of LED bulbs someone could power given a certain V02 Max... hmm.

Very interesting to know roughly how much energy one can create doing this! Being part of the current trend of people riding at home on Wahoo Kickrs&#x2F;Zwift and other turbo trainers, I do feel like that energy could be put to use somehow! Even if it were just to power a fan to cool myself down whilst riding, it would be nice to think the energy was being put to good use!

&gt; What I really don’t relish, though, is losing Internet access<p>In my experience with Comcast Business Internet, their upstream equipment goes offline a few minutes after a power outage. So regardless of how you&#x27;re powering your own equipment, it&#x27;s hopeless.<p>The cell network appears to persist through power outages, but bandwidth, packet loss, and jitter aren&#x27;t ideal in the best of circumstances. When it&#x27;s the only Internet access for the whole neighborhood, you should probably just give up on your videochat meetings...

My blog is solar-powered.<p>Unfortunately, since late September, solar can&#x27;t keep up. (Not a surprise given my suboptimal conditions.)<p>A bicycle as a generator would probably allow me to have a bit of exercise and easily provide enough power to get my blog through the day.<p>1: <a href="https:&#x2F;&#x2F;louwrentius.com&#x2F;this-blog-is-now-running-on-solar-power.html" rel="nofollow">https:&#x2F;&#x2F;louwrentius.com&#x2F;this-blog-is-now-running-on-solar-po...</a> 2: <a href="https:&#x2F;&#x2F;louwrentius.com&#x2F;solar&#x2F;solar.png" rel="nofollow">https:&#x2F;&#x2F;louwrentius.com&#x2F;solar&#x2F;solar.png</a>

Don&#x27;t do this for environmental reasons. You&#x27;ll never make back the energy embodied in the generator: <a href="https:&#x2F;&#x2F;www.lowtechmagazine.com&#x2F;2011&#x2F;05&#x2F;bike-powered-electricity-generators.html" rel="nofollow">https:&#x2F;&#x2F;www.lowtechmagazine.com&#x2F;2011&#x2F;05&#x2F;bike-powered-electri...</a>

Rowing machines are in my experience much more efficient. 200W is maintainable for an hour or more with some experience. (2 minute split, for any rowers out there). 60W (3:00&#x2F;500m) is genuinely difficult to pull - any effort at all will exceed that.

The reported 1 hour power seem to be on a low side. Average untrained male should not have much troubles generating 100W. Reasonably fit male that cycles regularly should be able to put about 200W. For longer intervals the power will of course decrease.<p>Still of course the power is low comparatively to traditional sources.

Is there a good way to put a generator on the bike itself? To say charge a powerbank&#x2F;phone? I have a crappy bike (no gears, tons of rust) and I have a bad habit of going as fast as it lets me good. However I honestly don&#x27;t really want to go faster than 15mph or so b&#x2F;c it&#x27;s generally unsafe. The problem is I have some mental block of making myself go slower. I guess I enjoy the workout. So I want to put in a resistance in somehow that I can crank up to make myself go slower. Does anyone have an ideas?<p>The generators I&#x27;ve found online seem kinda whimpy and just slide on the exterior of the tire&#x2F;rim. Is there is something more hardcore I can put on the chain or something?

I wonder how much more efficient the generation could be? 60Watts is still somewhat impressive in the rig mentioned, but I wonder if maybe better control of the rpms of the generator (through gearing) could give more efficient generation. I feel like at the gym, the workout bikes (which I think are generally powered by pedaling), will give you a wattage output that seemed higher than than 60 watts, but again, that&#x27;s about resistance (and not taking into account the inefficiencies of power generation). Seems like it could be made usable for a daily power generation machine (reminds me of &quot;Oxygen Not Included&quot;, where you have the person run on a hamster wheel to generate power).

&gt; Actually, generating power with their muscles provides a valuable lesson for kids, whether or not the power goes out.<p>The article ends on this point about parenting philosophy, but I think the author does not set up or discuss it enough.<p>What I don’t exactly understand is the underlying suggestion to manufacture this project as a “hard lesson” for the children.<p>I believe it is widely understood that children learn very much by emulating their parents. So what the parent regards as important, their children will see, and internalize those behaviors.<p>When I see parents worry about children taking something for granted, it can look like parents feel regret about parts of them that they see mirrored in their children.

How cloudy does it have to be for a 3rd &lt;$100 solar panel to provide less than 0.06 kWh of charge over 1 day? Clear skies are of course always better but I don&#x27;t think I&#x27;ve ever heard just how bad it is when they aren&#x27;t.

Better off using an electric car.

I&#x27;m surprised this made it to IEEE&#x27;s website, as bicycle generators are long understood to be unsustainable.<p>I think more could be gained by a small wind turbine or even a small water turbine, although those are definitely more complicated.

The author claims to have 200 watts of solar panels but only 420 Wh of battery, and because it&#x27;s lead-acid only half of that is really usable. Unless they live somewhere that only gets 1-2 hours of insolation per day [0] that is nowhere near enough to store an average day&#x27;s generation. Likely most of the energy is likely being wasted.<p><a href="http:&#x2F;&#x2F;www.bigfrogmountain.com&#x2F;SunHoursPerDay.html" rel="nofollow">http:&#x2F;&#x2F;www.bigfrogmountain.com&#x2F;SunHoursPerDay.html</a>

When energy gets dug or pumped out of the ground so cheap, you forget how hard it is to generate 100W, and what you&#x27;re calling on in resources every time you turn on lights or drive a car.

If you want a sustainable intermittent power source and you don&#x27;t have a stream nearby, you can&#x27;t do better than a solar panel. They&#x27;re ridiculously cheap these days and, with a bit of battery backup, are a far more practical electricity source than human muscle power.

Obligated to mention &quot;Oxygen Not Included&quot;.<p>The game features &quot;duplicants&quot; in a futuristic scenario trying to survive in deep space. The first technology to produce power is a sort-of hamster wheelie that one of them has to cycle on to generate power.<p>Very funny game.

There&#x27;s gotta be a more efficient way to covert the biking power into actual power. Anyone know?
