If you haven't seen the classic movie Soylent Green, now's the time.
a bicycle powered generator would save me so much on heating bills
Sustained human pedal-powered energy output is about 500W for world-class cyclists and around 100–200W for average people. Your body also produces ~100W of heat energy by simply existing, and that can rise to about 500W when exercising.
So the output range we’re looking at here is something like 300–1000Wh per hour depending on your fitness level and exercise intensity. 1 kWh costs ~10–30 cents around the world, I think.
You’re gonna spend much more on extra food to fuel your pedalling than you’ll ever be able to save on heating bills :)
just eat strawberries in front of a fan maybe ill get a nice pod with pretty images and music when i go...
Yeah every so often I see someone suggest bicycling is not so good for the environment because it takes the total calories burned without subtracting the calories burned by someone just existing for the same time period. If we could produce a lot of power ourselves then losing weight would be super easy.
That’s a weird argument, since cycling is the most efficient mode of transport. Even ignoring all the health improvements/lower emissions/etc., it still easily outpaces everything else in terms of environmental benefits due to its efficiency. It’s just not a good way to heat your home.
yeah no idea why but it pops up every so often for me in places like this. Again its due to someone using total energy consumed by the human during cycling without minusing energy consumed if not bicycling. Which is a pretty big difference because we burn like 2k calories just existing each day but if you ever got on one of those excersise cycles that track how many calories you have burned you will find out how taxing it is just for every 100 calories and I can bike places without it being taxing at all.

Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
