HID Conversion

This is a nice study. The study on the effect of the headlights on during daytime. Headlights is one of the tools that avoid accident in the road so it is important that car lights should be of best quality.

LED HID Head Lights

Nice Study Indeed!I like the lower wattage bulbs, it does take less energy. I like the LED lighting . I like to feel safe on the road and by using driving lights is a must! Thanks for the good read!

I'd just like to point out that, through my research, the global average of all internal combustion engines is 13% usable energy taken from whatever fuel is used, may that be gasoline/petrol, diesel, propane, acetylene, hydrogen, or the ever popular "nitro-methane"

LEDs are awesome. The problem is the average Joe does not have expensive LED bulbs, Audis or BMWs. Remove cool LEDs from your equation and just target Halogen DRLS @ 100 watts per vehicle. I sure could use an extra $60 bucks in my pocket per year after I disable my Halogen DRLS.

Projector Headlights

Those are some pretty reasonable numbers regarding the costs. You are right. Turn them on only when needed. You can save money and energy for this.


morgstickNovember 7, 2011 The chevy volt has a battery of 16 kWh, menniag it takes 16 hrs to charge the battery at a rate of 1000w per sec, or 57,600,000 joules stored in the battery. It would run a lightbulb of 100watts for 576,000 hrsWatt equals joule per second (watt is a rate)1 Joule equals 1 kilogram (2.2 lbs) moving 1 meterAverage car weighs 1500 kg (chevy volt is 1700kg)So it takes 1500 joules to move a car 1 meter2,414,016 joules to move average car 1 milePS chevy volt can only go about 35 miles on the battery alone (it isn't 21 miles because this doesn't take into account friction less than 1 and )


September 3, 2011 The question is wrong but based on the info pdovired the energy consumed per mile will be between 0.2 and 0.4 kW-h per mile. If the car is travelling at 60 miles per hour and has a range of 40 miles, all the energy in the battery will be used up in 40 minutes. The power consumed is a different matter. The rate of energy consumption will be between 12000 and 24000 watts (120 to 240 100-watt light bulbs!) These figures sound more like what you'd expect for a car pulling a trailer than for a small car.


well it depends on the baertty type and the solar panel most have so little watts that they cant produce unless in full light and you can trickle charge which is just below the baertty output voltage the baertty the solar panel voltage will not be the same when it draws power as your baertty will not be same voltage as when its under load the voltage of the baertty is only important to the appliance it is powering so you can attempt to charge it but it will limit the baertty life and will eventually leave a bad memory on the baertty as a project OK but not for everyday use


I had 2 hours or so (on a 7 hour baterty).Running down baterty to a low value is very bad for it and shortens its life.I wont get sucked into that again, Using it on baterty until 20% then charging then unplug and work off baterty again and repeat this and a few times the baterty life is back? to over 7 hours again.I dont recommend doing this procedure at all.


Washing only a full load in cold water. Saves 220 water heater.Try not to use oven till cold wheetar. 220 runs ac more too. If it is gas, it runs the ac more.Keep the sun out.Caulk around the windows.When not using anything, turn off.Put fridge and hot water heater on save.Keep thermastat over 75 in summer.Under 75 in the winter.Use fan to draw air through the rooms.Use fan in room you hang in. And where you sleep.You can save from $75.00 to $200.00.Watch your out side lights. A timer can be set on those.
