Hi M A,

I’ll share with you some material provided by Dan Martin which I found very handy and very interesting:

“The one EV car I currently have (have 2 vehicles that run on hydrogen also) I converted from a vw bug and is free to charge. As I live completely off the grid all my electricity comes from solar panels and 2 wind generators, which I also built.

However I did charge up at Costco in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00

Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I’ve converted 3 of my own cars (a datsun truck, ford ban, and a vw bug) and a few for neighbors. I’ve also converted cars to run on hydrogen, ethanol and biodiesel, by far EV is the easiest.

If you’re interested here’s what it would entitle…

– The engine compartment is first cleaned out of any gasoline components.
– Electric components are then installed in exchange.
– A battery bank is built and incorporated.
– Existing starter and driving systems are connected.
– Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.
– The system has normal automotive top speeds and acceleration, typical to the vehicle your modifying. If your top speed was 85 mph and your acceleration was 1 mile per min, then this will be what your left with after the conversion.

The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.

Typical tools, hardware & supplies are used, making access to parts available for all.

Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.

Project lengths range from 1 day to 1 month.
If you’re interested I wrote a guide on it which is available at www agua-luna com

My last EV conversion ran me about $1400. Everything is available online. I have a how to do it yourself guide available at www agua-luna com that will walk you step by step through the process. If you have ANY questions feel free to contact me through the site. Here’s a list of what you’d need…

Advanced DC Motor
The motor is an 8″ Advanced DC series-wound motor. It weighs 107 pounds and is rated at 68 peak horsepower. These motors are available in several sizes.

Adaptor plate
The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum and is pre-drilled with bolt hole patterns for both the motor and transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission and motor. Adaptor plates are available for many cars.

DC Motor Controller
The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis and DCP.

Potbox (Potentiometer)
The potbox is a 5K ohm throttle between the controller and the accelerator, similar to the way a sewing machine pedal works. The potbox’s lever arm is attached to the existing accelerator cable.

Main Contactor
An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.

Circuit Breaker
A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood and can be switched both off and on from the drivers seat with an extension or cable.

Main Fuse
The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.

Shunt
A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high and low power configurations.

Charger interlock
A relay that keeps the circuit open so nobody will inadvertantly drive off with the charge cord plugged into the car.

DC/DC Converter
The DC/DC converter is similar in function to a gas car’s alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.

If you interested I offer several DIY alternative guides to walk you step by step threw EV conversion process at agua-luna com or

If you think wind and solar are free, or even cost competitive, you have not done the most rudimentary homework.

Wind is typically 3x the cost of coal fired power. It is unreliable; when the wind does not blow, you have to have a conventional power plant to back it up. The average output is about 20% of the installed capacity, so you have to build 5x as many wind generators as you supposedly need. When the wind is less than about 30 knots, the wind farm puts out less than full power, so you have to run the backup power station to take up the difference; but then it is operating at part capacity, so its fuel consumption and emissions per KWH generated are higher. Wind farms are low-intensity, meaning that they take up a lot of land for a given power output. One state figured out that to meet the state’s ‘20% renewable’ energy mandate with wind power, they would have to cover 1/5 of the arable land in the state with windmills. The neighbors don’t like them and the noise, especially at night. Even with the tiny percentage of the US power consumption we now get from wind (a few percent), the wind farms are killing 440,000 birds a year, and no one knows how many bats. The wind farm at Altamont Pass, CA (east of Oakland) is killing endangered golden eagles at over twice the rate that the population can sustain.

Solar has similar problems, and is even more expensive.

Probably because of years of big oil propaganda. I know I look a conspiracy theory nut saying this, but just look at some of these answers. Its sad. If they worked better, we would be using them. We aren’t using them, therefore they must not be better?? Are you kidding me? Do you know how much money oil companies spend lobbying not to spend grants on renewable energy research, or other forms of energy in general? Car companies and other industries that rely on fossil fuels like coal, natural gas, etc… Do this as well. They make too much money as it is, of course they dont want change.

We could make a lot of progress on renewable energy sources and ways to package it/store it if our government (and corporations) cared at all about anything more than money. General it they constantly say it isn’t an issue, and that global warming is fake, and that there is no alternative. We are the US for Pete’s sake. If it doesnt exist yet, then we should be making it happen. But no. We are controlled by greedy fat bastards

The UN is there as a token to say they do something. The armed drug lords are better armed then they are. Children have been raped in front of the soldiers and they do nothing because that is not part of their mandate.

This is the UN that never is talked about. It’s a joke and a farce.

admin answers:

Solar panels currently being manufactured, have a design life of 20+ years.

Home-size wind turbines have a wide range of design lives. The turbine life is influenced by conditions of use — high winds, ice on the blades, etc.

I would recommend that you purchase your home-scale wind turbine from a seller who offers a guarantee to repair or replace the unit if it fails under normal use. A 5-year or 10-year guarantee period would be ideal.

A hand crank won’t provide very much power. Forget powering your TV or refrigerator.

You may be able to make something work with a 12V generator connected to a stationary bicycle. Use it to charge a battery which will power an inverter to operate your appliances. You’ll be spending plenty of time pedalling, so make sure you have very efficient appliances.

You could supplement battery charging with a small wind charger and photovoltiac panels.

admin answers:

Many people are not using solar energy for their daily need, probably for 3 main reasons:

1. Lack of awareness
2. Cost of installation
3. Breaking off from the grid electricity or Integration to the grid electricity

Until lately, most people are not fully aware of the enormous energy that could be directly tapped from the Sun. It’s still costly to obtain the pvcs for collecting the sun rays to covert to energy and where most areas are connected by grid system, how does a standalone electricity generator blend.

This is a very important question!

I am a big fan of Dr. Jack Edwards from the university of Colorado. In 1997 he wrote a paper titled “Crude Oil and Alternate Energy Production Forecasts for the 21st Century; The End of the Hydrocarbon Era” Jack was an optimist and formerly in charge of Shell’s Research Centre in Houston. I will read some of his key predictions on “Peak Oil”.
Conventional Light Oil – 2025 All Oil – 2035 All Natural Gas – 2035 All Coal – 2040. Conventional Oil Peaks at about 38 Billion Barrels per year globally and tails out at 9 Billion Barrels by 2100. All other energies from fossil fuels face the same basic fate by 2100 as a percentage of Peak (9/38=23.6%) by 2100. The reasons for the decline vary, some are supply based, some are economics based and some are environmental (coal). He estimates that at Peak Oil that Nuclear will be about 5 Billion Barrels Equivalent or roughly 6% of total supply (I believe the actual current figure is about 8%). He shows Nuclear expanding to about 15 Billion Barrels or roughly 16% of total supply by 2100. The interesting fact is that by 2100 we will HAVE to obtain 35 Billion Barrels or about 37% of Energy from Solar, wind and Geothermal. Currently we obtain less than 3% from these sources!
None of Jack’s thinking revolved around such things as “cap and trade” and its chilling effect on the supply curve!If NA is ever going to achieve the substitution of the fossil fuel supplies with the alternatives, we will require that ALL sources of fossil fuels be exploited fully. Otherwise we will neither have the energy nor the economy to reach a 12 fold increase in solar, wind or geothermal let alone the substitution of another 22% of the energy supplied by coal! Theadagee of “it takes money to make money” is true and can be stated as “it takes energy to make energy”.

The Nuclear Industry will be essential in meeting energy demand, however the rush to meet the lofty goals of substitution will require absolutely enormous quantities of Capital and has the potential to create a catastrophic environmental and security quagmire! I am most afraid if the fact that there are environmental approvals (Nuclear) pending in my country, that in my technical opinion, are a catastrophe waiting to happen! Nuclear has a vital role to play, however when these kinds of $$$ are involved, big corruption and big mistakes are also in abundance. When I was in University, I learned that the Geotechnical aspects of Nuclear site selection were paramount in the decision tree. In reality economics are paramount and the Geotechnical safety issues are out 10th out of the top 10 considerations. Politics is the #1 consideration.

I fear for the long term economy of North America. There are going to be very major changes on the horizon, however it is possible to accomplish energy security but at a huge cost. The biggest risks relate to the economic uncertainty that current geopolitical movements such as “global warming” are causing. While these uncertainties exist…Capital will do nothing! This will make the problem deeper and broader, and the economy will continue to suffer.

Solar Panels In Cold Climates
By Anna on November 26, 2008

Contrary to popular belief, you do not need to live in a hot climate in order to benefit from clean renewable energy sources such as solar power. In fact solar panels convert sunlight into electricity more effectively in colder temperatures…………………………..This phenomenon is due to the fact that the colder a material is, the better it will conduct electricity. Therefore, solar panels will produce less electricity in a hot climate than in a cold climate given that the amount of sunlight is equal. It is true that colder climates tend to have less sunlight than hotter climates, but the reduced availability of sunlight is offset by the increased efficiency of solar panels in colder temperature.

A good example of this principle in action is the Photovoltaic Solar Power Plant in Colorado, near Alamosa. It is home to one of the largest photovoltaic solar plants currently operating in the United States.

I hope the above is informative…

I understand your objective Richard, but would sincerely recommend that you re-consider how you should go about achieving it.

I don’t recommend 12v batteries for your project and certainly don’t recommend using anything less than first quality batteries – you can still find them at low prices.

A better storage solution is deep cycle 6volt batteries. The 6v batteries will do a much better job, last longer, allow a deeper discharge and a higher number of re-charge cycles.

You want your batteries to be the same size, type and age to work together best. I use 4- 6v batteries in my RV along with a single solar panel and can stay out in the desert for days without ever having to fire up my generator.

Here’s a link to a great article on the subject:

Big Business is beginning to look at global warming through eyes blinded by dollar signs. Climate change is replacing tech and bio tech as the major investment theme of the future. Wall Street’s analysts are devising ways to cash in on weather.

Discussions have changed to talk of what a 1-degree rise each year in temperature would do to profits. Global warming is becoming a major market-moving force that represents a generational shift likely to influence how people invest for decades. The world’s biggest financial services firms are investing massive amounts of time and brainpower trying to pinpoint what stocks and sectors will benefit or be hurt by Global warming.

There are at least 74 companies in 18 countries that can profit from changing weather patterns. Global warming will change world economy. There is a company in California which manages the largest pension plan in America that has committed $800 M to invest in clean technology. At this time 90% of global warming is the result of human activity.

Temperatures around the globe could raise 2 to 12 degrees Fahrenheit by 2100. This will result in more intense heat waves, stronger tropical storms and a rise in sea levels that will swamp low-lying cities and farmland. When I was boating through rice fields in India last summer I wondered how these people would survive even a few inches rise in water. Most of the farmers live at sea level.

Corn will be used to create ethanol. If corn is used to provide even 10% of the nation’s automotive needs, it would use 35% of America’s corn crop. Since 25% of all food prices are affected by the cost of corn, we could face a corn vs. Food situation. Farm leftovers can be used to create cellulosic ethanol for fuel. Farm equipment companies should do well because farmers will be rethinking harvesting techniques. They will also retool their machines for the new fuels. Monsanto is working on creating more drought resistant crops.

Energy conversion devices and sun power are becoming buzz words. Windmills. Fuel cells. Solar panels. Several companies are developing types of clean solar panels with the hope of rivalling oil and coal, deemed “dirty” fuels. Eco technology is still too mature to make a lot of money. Solar will only create a tenth of the world’s energy. Technology that makes dirty energy sources like coal and oil cleaner. There will be more money made on the dirty stuff. Nuclear power generators are also on the rise. The new nuclear energy is much cleaner and produces no carbon.

Ethanol, hydrogen, clean diesel, bio diesel fuels hold promise for the future. Hybrid cars are the way of the future. The major car manufacturers are working on increased efficiency. Investing in hybrid vehicles and components and batteries etc will be good investments.

The insurance industry will change incredibly. So many energy and utility companies will all have to face different challenges due to the effects of weather. Suddenly they realize climate and profits are closely related. Investors will start to lean more toward green investments.

I also think security and protection companies might do well because the displacement of people and shortages could result in an increase in crime.

The world’s demand for energy is accelerating as China and India grow. Heavy construction and engineering companies that build power plants will do well. The smart ones will build ecologically sensitive plants will steal market share. They will find ways to make plants more efficient and cleaner. One technology, clean coal, puts devices in smokestacks that pull the carbon out of the exhaust and plow it back into the soil.

After Hurricane Katrina, folks are rethinking the option of coastal real estate. People will develop an aversion to locations on the water and severe-weather-prone areas. People will flee Florida for the Smokey Mountains for example. This covers Georgia, Tennessee and North Carolina. This is already happening. Also the high insurance premiums for living near the water affect property values.

Small parts and components that go into everything from washers and dryers to fighter jets and elevators could play a gigantic factor in curbing energy use. We already have the technology to reduce the world’s power use by 30% overnight. About 11% of the savings could be achieved with efficient electric motors inside washing machines, conveyor belts and other motors that use half the energy of older technology. Another 11% could be saved in transportation using hybrids. The last 8% can be saved with energy-efficient fluorescent bulbs. Currently businesses that focus on energy efficiency are already becoming more profitable.

The wealthier nations are in better condition to deal with these things. It is the poorer nations that will have serious difficulties. Holland could just disappear. A great deal of landmass will also be lost, which will drive up the cost of real estate everywhere.

That is how America sees the future according to Global Warming. In its usual entrepreneurial way, Americans see the silver lining of this problem as an opportunity for positive change and innovative growth.

No. Air drag is one of the chief components in auto efficiency. What you describe would increase air drag.
As far as the solar part goes most cars have about 12 square feet of surface in the sun when the car is in the sun. 12 square feet can produce 900 watts. In four hours that would be 2700 Watt hours. A gallon of gasoline is about 37,000 Watt hours. What means is is that it is going to take over 100 days to produce the energy of one gallon of gasoline and everything has to be perfect.

I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.

admin answers:

They already are, the Honda FCX and Toyota FCHV are both available for lease in some areas. The price for either car is probably prohibitively expensive which is why they’re only for lease, the fuel cell itself is very costly.

Right now, the hydrogen fuel cell is a poor idea for cars for the simple reason that it always requires more energy to separate it from whatever it’s bonded to than you can get back out by utilizing it. There are ways to make it more efficient but it’s still a losing proposition. As an energy storage medium it’s not efficient enough. Until we can use it in a fusion reactor it’s not likely to become our energy source whether it’s reformed from natural gas, made via electrolysis or by catalyzing metals. It’s just more efficient to use the energy directly instead of making the hydrogen and then either burning it or using it in a fuel cell.

Batteries or capacitors are better means of storing electricity and that electricity can be produced using a variety of renewable sources – with smart investment we could change to renewable power generation and electric cars within a few years.

I could be proven wrong of course, Honda is going ahead with it’s plans for the CVX and Toyota is doing the same. I do like the possibility of home charging and you can use the generator to power your home in the event of a power outage, as long as you continue to get natural gas supplied. But natural gas reformed into hydrogen isn’t terribly efficient and still relies on the fossil fuel model with associated problems.

If you use a high-efficiency method like QSI Nano claims to have developed and pair it with solar thermal tech then you may have a winner. This is even more true if the work by the Weizmann Institute proves practical, see http://www.greencarcongress.com/2009/04/weizmann-institute-scientists-demonstrate-novel-approach-for-splitting-water-into-hydrogen-and-oxyge.html#comments

Not only cars and calculators, they are used in a variety of fields. They are used in transportation signalling like light houses, aircraft warning lights and road traffic warning signals. Moreover in remote places where energy supply is unavailable, solar energy is used. It is also used in home appliances like solar cookers and solar water heaters. Solar cells are used in electricity supply. In addition solar batteries can also be used which could store power generated from the sun and discharge the power as needed(through an inverter).

admin answers:

They’re called Amorphous silicon cells. They’re about 7% efficient.

admin answers:

Not unless you can figure out a way to produce a semi-conductor at home. Basically a solar cell (photovoltaic cell) is a couple of layers of silicon P type and N type. Electrons become excited when light quanta penetrates into the P layer. The excited electrons move to the N type and (very oversimplified) create electricity.

I doubt you would have the facilities to create the materials at home.

admin answers:

TV, lights and small appliances, yes. Washer, maybe. Dryer, not likely unless it’s gas – consider a clothesline. Electric range or oven, no. Hot tub, no unless it’s converted to a gas heater.

The raw panels are about $3-8 per watt. So for 6Kw figure about $18k for the panels. The charger/inverter and batteries, figure $2-3k more. Figure about $30k including the installation.

You might also consider a generator. The off-grid houses I’ve seen tend to have them, even if they have batteries too. Add $3k for that.

Do you have a creek? Consider small-scale hydro too.
