MODERATORS
1 gal of gas: ~29k calories - $4.609
~29k calories of rice: ~$600 <-- sus math btw 🤔
It's simple: drink the gas.
okay, update:
my math was wrong. new cost of rice: ~$11.5 (ordering in bulk)
CONCLUSION
Drink the gas.
100 grams of raw white rice is 365 calories, meaning that it's about 3650 calories per kg. 29k calories of rice is 8 kilograms.
Where are you buying rice that it costs $75/kg???
I did my math wrong lol
Found some at 66c/lb. Need 17.5 lbs. $11.5 👌
If you drink a whole canister of gas, that's enough to cover your nutritional needs for the rest of your life!
BRB
Also, gas is less toxic than vitamin C. So you should be fine! :D
Taking this further, that $4.60 of gas will power the most efficient car for about an hour.
That $12 of rice is enough energy for you to power your bike for like 50 hours.
Conclusion: Just drive your car. Do you really want to waste 49 hours on your bike? /s
But that's because that fuel is used to do much, much more work. if you scale down the unit to, say, a scooter (50cc) it will last much longer. Most scoots have 1gal tanks and they can get over 100mi per tank.
That being said everyone will think you lost your license due to drunk driving so to prevent this you should replace alcohol in your life and simply drink gas.
Real ones will switch to drinking biofuels because they're better for the environment.
Ethanol is a good option.
Pro-tip: make sure it's not denatured and is purified—it's less dangerous for consumption that way.
Wait a second...
No, drink diesel - more calories per gallon, even though it costs more per gallon, too. The calorie difference is more than enough to offset the cost difference.
drink diesel ? I thought the obvious conclusion was to fill up my tank with rice
If you bike regularly, you actually don't spend more calories. You only see calorie burn uptick when first taking on new exercise, which falls off over time back to your usual normal calorie cost. Because of this, that calorie cost for a biker is calorie intake they'd already consume even if they didn't bike. It's essentially free, in contrast to the gas of the car which is always a cost.
Checkmate liberal. /s
You can't convince me of free energy
NICE TRY SCIENTOLOGY
There was a Kurzgesat video about this a couple weeks ago. Apparently if you don’t spend calories exercising/biking, your body will find other ways to burn it like increasing your immune system activity (which can have poor long-term effects). There’s an adjustment period when you do start exercising where energy is still spent on sedentary things and the actual exercise before the former is reduced to mostly match the latter.
I have also read that regular exercise can lead to an increase of base metabolic rate by ~5% though, which is like an extra 100 calories per day.
You should always doublecheck Kurzgesagt videos, btw.
They're not a good sole source due to being heavily simplified (they know this and often provide further reading (you probably also know this (just commenting anyway for general visibility (this should be considered good practice tbh (to be honest)))))
Yeah, I started taking Kurzgesagt videos with a grain of salt a while ago, hence the “apparently.” Their explanation just fit NoName’s assertion pretty well. Never bad to make the possibility of being wrong explicit though!
Seems like a potential circular reference though, judging from how popular Kurzgesagt videos are.
One thing to account for is that humans are very inefficient at converting food into energy output. Only about 25% efficient to be precise. So you need to eat about 4 times more calories than you end up outputting into the bicycle.
The same thing applies to ICE cars, their engines are also very inefficient. EVs however reach an efficiency of 80-90%, they only end up using more energy than a bicycle because of how much faster you usually drive them. But if you drove an EV at the same speed you would ride a bicycle they would be vastly more efficient. And that's not even accounting for the amount of energy used to produce food in the first place, which is a lot higher than the energy content of said food.
The superior choice is obviously an electric bicycle though when you want to have the most sustainable transportation, you get all of the efficiency gains from a battery operated motor, whilst still having the low weight and drag of a bicycle
"low drag of a bicycle" citation needed
That's not accounting for the inefficiency of turning heat into electricity in the first place (turbine generation is about 90% at utility scale) or turning photons into usable electricity (photovoltaics are at about 20%). And with turbines, you have to account for the inefficiencies in processing the fuel to get it to that point.
The whole universe is just an entropy generator and we're gonna lose a lot of useful energy as we try to manipulate it.
Yes, I was purely referring to the efficiency of the battery and motor. Producing food also requires a significantly more energy than the food ends up containing
Gross metabolic efficiency is gonna be around ~25% so you're best off measuring kilojoules of work as an approximation of calorie burn, and then compare that to how many gallons of gas would be consumed when in a car, but you'd still probably wanna drink the gas
