can a weed eater engine (2cycle) turn a car alternator and charge a 12vdc battery?

hector596 questioned:

can that size of engine yield ample rpm (if collectively to a car alternator) to payment my 12 volts dc battery ?

Can you wire 2 identical 48v motors in series to generate 96v?

kenkidd questioned:

I too am effective on building a home-built hybrid so as to proffer the array of an EV. I am inane to use a combustion engine to spin the motors.

If each 48v motor produces 100 amps independently, when collective to start 96v, it must only subdue grant 100 amps. At smallest amount that’s how it facility with batteries, assess?
Bonus info. I have 2 48v dc 100 amp gripping motors that I want to use as generators. I plot to turn these using a gas engine. I need the productivity potential to be 96v dc 100 amps. Can I get by wiring these generators in run?

5batteries on freight train have power for 1 hr each and charging time is 3hours on each, pulling generators?

sbachhal questioned:

the generators are assembled with rotary and wind energy owing to a tadem differential axle to a gearbox with flywheel to a generator, here are transmission lines privileged than the tracks to transmit electricity, some of the potential will be used to payment the batteries by hegemony logic. The teach is full to 50mph while the genorator is not be used so teach engine is off at 50mph and genoraters are now tansmiting potential till speed is 10mph and the repeating is what you do. simalar to hybrid car but on a larger extent with larger forces at work. radius of wheels attacted to the axle is 5 feet.

Has the US Dept of Energy produced anything useful in the last 25 years?

sside_chicago questioned:

Bush says he will boost Dept of Energy costs by 25% on renewable fuels, nuclear, and efficiency.

I retract the Dept of Energy effective on tar sands, “inherently safe” nuclear reactors, sterile coal technologies, and methanol powered cars. None of these ever twisted into anything cash-making. Is here anything they have done helpful in the last 25 being?

I need a formula for efficiency?

BradG7 form the Fugitives questioned:

I have the time an engine ran, the amount of fuel consumed, and the outdoor like, I need a formula for the efficiency.
It’s a generator really, but subdue an engine, right. I was in tension I may maybe Get out of needing that in rank. Isn’t here any additional way, kinda like MPG, you don’t need that much uncommon info.

whats a good store to buy a solar panel to charge 6 car batteries?

Brian . questioned:

i also dont know what size i need to payment them.
ok i see that car batteries force not be a excellent thought. may maybe a name recommend a excellent way to store the potential?

Is it possible to use the motion of a car’s wheels to charge a battery for an electric engine?

Billy questioned:

I’ve read that the Toyota Prius uses a combustion engine to payment the battery for its gripping engine, but is it possible to use the budge of the cars wheels, once it is running, to payment the battery as a substitution for. It would demand a lot less gasoline in the long run. Wouldn’t it? I’ve never full a physics rank, so maybe this isn’t even possible. I don’t know. What do you guys reflect?

What is the limit time to stop being critical and how?

Electricstrongking questioned:

All of us know that mankind make alot of progress in view of the fact that the founding of iron and oil. The two bits and pieces make mankind able to make a splendid leap from the prehistoric or marble age era.
Public become more essential headed for the background and try to search for something new. The invention of engine has made a huge donation headed for mankind. Investigate on the engine has start a better fuel consumption and cleaner emanation exhaust gas. Investigate on clarification has made progress a lighter body clarification. Investigate on aerodymanic and radiation contain in the progress. If you reflect additional isn’t it that essential thought will lead to efficiency. Cars will have the affect that give up the lowest polished strong and colorless color radiation for energy efficiency. The downstream is that will lead to a unimodel and unicolor for all cars. What would be the aestetic side? Here is time when essential tought work hostile to aestetic feeling. Nerdy hostile to actor. Isn’t mean that mankind will stop chat for being?

When are we going get hydrogen cars ?

Rob questioned:

I know the main problem is making the tank small ample to fit in a car and make it safe .But do you reflect in th next 5 or 10 being they will make it safe and small ample to fit in a car?

I know hybrid cars are out and are excellent for city driving but not excellent for driving on a highway .The battery is use in the city and the gas is used on the highway . But hybrid cars are fake has you have to use the gas to payment the battery .So you subdue have to go to a gas rank and it will run on battery in the city but on the highway you need the gas has the battery is not powerful ample.

Here are some new hybrid cars .But the problem is they are not powerful ample on the highway and you need to payment the battery .So they are only excellent for city driving.

Now gripping cars are okay but 4 tribulations.

1. They are not powerful ample on the highway
2 .Where do you take it to plug it in to payment ?
3 How long does it take to payment
4 How long will it run with out needing to be payment again.

Inane to a gas rank takes 2 summary but I do not reflect it will take 2 summary to payment

Can I recycle inverter energy by adding car alternator to charge battery?

haroldezeugwu questioned:

Gentlemen

Thankfulness for answering my previous question viz: can I give a new lease of life battery by charger collectively to the AC give from the inverter? I have seen from your answers that even if this is possible it is not not compulsory

My question now is: can I give a new lease of life the battery by way of a car alternator. That is, I potential a rotor, say, 100watt motor that will be coupled to a car alternator, which will then payment the battery. Really I want to eliminate the need for grid electricity in this project.

Thankfulness

Aircraft Fuel Consumption Per Person?

John questioned:

I want to know efficiency per self per passanger.
An A321 force use 24000 lbs of fuel to go place a stop to public. At 8 lbs per gallon that’s 3,000 gallons. With 150 passangers that’s approximately 150 mpg per passanger.
I would like figures for all aircraft (lbs burned per agreed number of miles flown).
Thankfulness-JD

Efficiency of an appliance?

A car has an efficiency of 58%. If it uses 8mj of fuel, what energy is twisted into helpful work?
Be grateful YOU VERY MUCH IN ADVANCE

The Prius or another byhrid?

steve00878 questioned:

Investigate the Prius or another hybrid. Outline for a fleeting time how they work and focus on a fastidious figure you find fresh. Are you impressed with the batteries, or perhaps the regenerative brakes?

And if here is anything in here you just don’t get, question – or tell it in your paper.

Then, take a spot. While hybrids do get better mileage, they aren’t automatically the best – the Smart Car, for model, gets better mileage. And a lot of the equipment in a hybrid is very “dirty,” in a manufacturing implication. It’s honest to say building a Prius makes more pollution than building a ordinary car. So the question is, does hybrid equipment really start a benefit, or are “we” fooling ourselves?

Will the Combustion Engine EVER be replaced?

Sweet Baby Jesus! questioned:

It’s been around forever. You see guys all over who aver they have uncommon energy sources adn equipment, this has been inane on forever. GM even had a levelheaded battery powered car in the 90’s. With all this talk about green household gases and the price of gasoline, why the crap are we subdue life sold 30MPG cars?
Hegemony, cash, lack of better alternatives?
I’m just not export this hybrid crap. The equipment must exist, right?
I guess the Road Fighter show wasn’t that far off. Just reflect of the oil cash that would be lost, the wars not fought, the frankness Americans would have if their cars may maybe be exciting at home. Has anyone here seen what they are building in Dubai??

Here is the EV1

I subdue can’t judge solar panels place of protection’t spellbound on in the mainstream, I guess it’s in view of the fact that they’re subdue so gosh dang pointlessly pricey. You can buy a $25,000 solar potential unit for a home and really make cash back on the electricity you don’t use and yield for the potential company and it comes with a 25 year warranty. Now if it was half that price that would be awe-inspiring.

What is the efficiency of solid-fuel rockets?

dragon69802 questioned:

For my Engineering rank, we each chose something from a list of engines, rockets, etc., all concerning heat conveying. I chose levelheaded-fuel rockets, having heard very modest about them, with the hopes of culture something new.
Anyway, for the project we’re doing, we have a list of criteria, and one of them is that it must contain the percent efficiency ratings for the differ. I’ve been powerless to find anything of the sort, so does anyone have an assess for what it must be?

How do you build a bomb calorimeter?

ttlee2151 questioned:

We are tiresome to find the efficiency of uncommon fuels by igniting them using a bomb calorimeter to rate heat.

Output from dynamos?

psychologist questioned:

If I fit two dynamos to each veer of my bike (not a logic), would here be enought potential generated to payment a battery with a fleeting while of fuel consumption with which the bike starts to run from the battery as a substitution for of the fuel in tank? More like the Hybrid translation.

Fuel efficiency using precalculus?

MrsPetticoat questioned:

The fuel efficiency (in miles per gallon) of an SUV depends on its consequence according to the formula E= 0.0000016x^2- 0.016x+54 (1800 ? x ? 5400), where x is the consequence of an SUV in pounds. According to the model, what is the consequence of the smallest amount fuel-efficient SUV?

This is pat of my precalculus rank so I cant use any derivatives, thats why im blocked on this problem.
Any suggestions?

fuel consumption of diesel engine?

Milk questioned:

how do you work out the fuel consumption of diesel engine knowing high energy regard of the fuel and efficiencies of generator and diesel engine aswell as potential voltage current etc.

how to compare efficiencies for a diesel and a diesel-electric engine?

silent h questioned:

I have no thought how to maybe even start interms of evaluation. i know for a ordinary diesel engine i can just look at fuel efficiency and by and large engine efficiency, but how would i do this for a diesel gripping engine??
