I purchased panels, inverters, and racks from ML Solar, right next to you in Campbell (60 miles from me, so I drove down rather than pay shipping). I paid under $ for a kW system, for $ per watt (without considering permit fees and other flat costs, but also not considering tax rebates) Oct 16, · @universityofky posted on their Instagram profile: “Like her sticker says, “Find your people.” College is a great place to do just that.

My DIY Solar Power Setup – Free Energy for Life
A common question we get about D. So, diy thesis theme discount, how about it? On the shaft are either permanent magnets or copper wire coils with a small DC current flowing through them. The flow of current creates a magnetic field. As the shaft rotates, this magnetic field induces current to flow in a matching stationary set diy thesis theme discount coils. ENERGY SOURCE: Where does the original source of energy for the alternator come from?
This eventually came to be known as the Laws of Thermodynamics. That means an equal amount is given up diy thesis theme discount the engine. The engine has to work harder and burns more fuel to be able to provide this additional energy. Another important concept to remember is that the mechanical energy of the engine is not PERFECTLY converted to electricity, diy thesis theme discount.
Some of it is converted to noise, heat, and vibration. SO, WHY NOT IN AN ELECTRIC CAR? The two main reasons are: 1 An E. Remember, the ENERGY that powers the alternator is actually the mechanical energy created by the engine through combustion of fossil fuel. Instead, it has an electric motor and rechargeable battery.
We COULD use the battery to spin the motor to spin the alternator to generate electricity. BUT at best, we would simply be using electricity to make electricity. Even worse, there are still losses on the way, diy thesis theme discount. Conversion losses often show up as heat, but noise and vibration as well. Essentially, using an alternator powered by an electric motor, we could only ever make a smaller amount of electricity than we started with.
If we could create an equal amount or more, we would have a Perpetual Motion Machine. However, diy thesis theme discount, we COULD make a different voltage. An electric car battery pack is typically over VDC, whereas we only need a 12V system for headlights, radio, and other diy thesis theme discount. This is an electronic device which diy thesis theme discount direct current at one voltage diy thesis theme discount converts it to a different voltage.
Converting to a higher voltage means also getting a lower current. Getting higher current means also getting lower voltage. Higher power converters have heat-sinks, fans, or even active liquid cooling, diy thesis theme discount. They are compact. They save weight. They are more efficient.
There are no moving parts — no belts to replace, no pulleys, no bearings. That also means they are maintenance free. Many converters allow for a range of input voltage and are listed as so. Power is rated in the maximum number of Watts that can be produced by the converter. In a car, you need enough power for the headlights, radio, and other accessories. This might be as much as several hundred watts. Electric Motor AS Generator: Lastly, the AC motors used in commercially-built electric vehicles make diy thesis theme discount generators.
Remember, we can only CONVERT energy from one form to another. There are still times when this is useful. Converting the KINETIC energy of a car to some other form electricity to charge a battery, or heat of friction from traditional brake pads will remove the kinetic energy and thus SLOW DOWN a moving vehicle. This is perfect when you want to slow down anyways! In another scenario, a vehicle can be coasting down a large hill or mountain.
The POTENTIAL energy is converted to KINETIC energy, diy thesis theme discount. In a manual transmission fossil fuel vehicle, the driver might downshift and use the compression of the engine to help slow the vehicle. In an electric car, the motor can charge the battery to do the same.
It should be noted that the battery needs to be at least partly discharged to have a place for the electricity to go for regenerative braking to work.
Alternators are neat technology, allowing us to convert mechanical energy into electrical energy. Similar technology is used on a large scale to generate electricity at power plants.
Alternators work great for fossil-fuel-burning vehicles, but are complicated, inefficient, and high-maintenance compared to DC to DC Converters used on Electric Vehicles. We hopes this give you a better understanding of alternators and electric vehicles for you to be able to work on your own Electric Vehicle Project. Energy is lost at every step of the conversion process. Even worse than that, we need diy thesis theme discount get the fuel for the vehicle to start with.
It takes a tremendous amount of energy to search for oil, drill for it, transport it, refine it, ship it to a gas station, and then finally get it in our fuel tank. Well, if u guys worried about the drag of alternator when car moving then why not giving it a clutch? And attach that alternator to another smaller battery to supply lighting and something else. The clutch only attach when not on gas the secondary battery is low. If the gear ratio to the wheel was such as it is on a ten speed bike or mountain bike then, the amount of energy used would not be a drag on the car.
Just as you shift gears on a bike to reduce the amount of energy used in pedaling to make it easier, you can do the same on electric cars using an alternator connected to the wheels. I wonder the same thing others do. Obviously an alternator cannot be ran off of the electric engine. And I am not saying that should make the vehicle never need to be charged off of a plug in source.
However I will use the new Ford electric truck for an example. They say the range will be miles with a 1,00o pound payload. So could alternators be used to increase the distance hypothetically speaking to miles? I feel like one of the selling points of electric vehicles is range.
I have one road trip I take at least two-three times a year that is miles. My current Chevrolet Truck can drive miles without stopping for fuel. I will not consider an electric truck until it can pull the same trailer, haul the same cargo and go just as far on one charge. Reading this discussion there was one suggestion diy thesis theme discount resolving this dilemma — what would happened if there where two separate batteries and some kind of alternator charging them separately one being use for drive when the other being charged and so one.
How come nobody is picking discussion on that? This sounds a bit like having two glasses of water and pouring the water back and forth between the two. You will never end up with more water than you started with. In fact, you will only eventually spill and have LESS water than you did originally. Reading some of these comments helped me understand how some can believe trump won.
Listen people, engineers have thought about this far before you did. Alternators ARE amazingly easy to spin by hand… UNTIL you place a load on them, at which time they become increasingly difficult to spin.
Just stop for a moment and think about that watt diy thesis theme discount amp Honda generator you used to go camping with. Why was it so heavy? Why did it need a two hp engine just to power the equivalent of 20 watt lightbulbs? Why do the engines of generators get larger as we ask for more output? Why do you actually hear the motor ramp up as you add more electrical devices or load to diy thesis theme discount generator?
