FAQ

I have a van and wish to kit it out with generator, welder and power tools. The genrator needs to cope with a 180amp rated welder plus 110v power tools (grinder, drill etc) being used at the same time. The generator needs to be diesel powered not petrol. The ones i've looked at are rated in Kva's. Not too sure how to work out how many Kva's i will require. Help please.

It will probably take something like 6.6 KVA's to run it. Similar one's take a 220 VAC, 30 amp circuit. The Model 180 MIG welds up to 1/4 steel. 6 heat settings and infinitely adjustable wire speed control welds a wider range. Max. output 160 amps with 30% duty cycle. Requires 220 Volts 60 cycle 30-amp circuit.

I am contemplating on getting a full house generator and need some feedback from you all.l. What is the best brand for quality and durability of a generator and what hp would I needThe house is about 2,000/sq ft, central A/C heat, all electric at the moment with the usual appliances.2. I want to connect permanently to breaker box for automatic turn on and will need fuel for it.3. In light of today's economy and potential collapse if one is in survival mode, is it better or cheaper to have butane or propane ?Also what size tank would need to buy, and how big is reasonable ? to last a good while or as needed.I am totally electric right now including water well pump so when power down, I'm sunk!!

With electric heat, you're into a large generator. 'Automatic on' means a transfer switch generator control panel. If you're thinking about 'survival mode' diesel is your best fuel option. (More widely available, less tech. support for refueling, and stores well.) You might consider an engine heat capture system for efficiency in winter conditions. You probably need about 20-25KVA to handle full load with heating. (That's only a 'guestimate, DO do the math before you select a unit.) This won't be cheap.

Having lots of diesel fuel to make electricity (200-800KW)is it better to use a diesel generator or a steam turbine?(Remember : the only way to produce steam is burning diesel)Does anybody know how many KWh can make per 1000gal?

Diesel generators in the 200 to 800 kW range are very common. The cost of anything above 600kW gets pretty high, but the diesel engine is much less expensive than a steam or gas turbine. The advantage to a reciprocating engine vs a turbine is that a reciprocating engine can better react to varying load conditions. Although a gas turbine is generally more efficient than a piston engine, they can not react quickly to a change in load. You also have a lot of excess machinery to utilize the high shaft speed of a turbine. There is one answer that suggests that you count the number of energy transfers. This can be a valid point, but you need to take into account the efficiency at which you are transferring your energy and how much waste heat you can recover and put to good use. A standard diesel engine turns fuel into work at about 35% efficiency, with little chance of recovering any usable waste heat. A turbine converts heat energy into work energy at about 40% efficiency. However, in the case of the steam turbine, a heat exchanger can be used to remove energy from the exhaust and preheat the boiler water, thus requiring less energy input from the diesel fuel, provided the system is at a steady state condition. In practicality, but a diesel genset.

Basically, I want to set up the new homestead off grid and would like to do it with a diesel generator to a DC disconnect, to a charge controller, to a battery bank, to the system meter, to the main DC disconnect, to an inverter, then to an AC breaker panel. Just like a solar array system but using the diesel instead of panels for the first year or two. The home will be using no more than about 22kWH daily. I guess the main question is how do I use a diesel generator in place of 19, 210W solar panels without running the generator 24-7?

Look okorder

i need to do a project and i need a website that has info on why solar panels are more enviromentally friendly can you please give me some websites?

What are the environmental benefits of photovoltaics? Because they burn no fuel and have no moving parts, PV systems are clean and silent. This is especially important where the main alternatives for obtaining power and light are from diesel generators and kerosene lanterns. As we become more aware of greenhouse gases and their detrimental effects on our planet, clean energy alternatives like PV become more important than ever. The burning of fossil fuels degrades our environment. It even is managing to change the climate of the Earth itself. The supply of these fossil fuels is finite. Just, in the last century, humans have consumed nearly half of all of the oil that will ever be produced. Consider this in the context of 5000 years of human history. The hidden costs are immense, including tax breaks for fossil fuel companies, increased health costs, the long-term costs of climate change. Rising fossil fuel consumption (releasing carbon emissions) was once favorably looked upon as a measure of economic growth and development. Carbon emissions, estimated at 93 million tons in 1860, jumped to 525 million tons by 1900, and to 1.62 billion tons by 1950. At the end of 1994, the atmosphere contained 4 billion more tons of carbon than just 12 months earlier. Violent weather cost the world a record $130 Billion in the first eleven months of 1998- more money than was lost from weather related disasters from 1980 to 1990 ($82 Billion). Researchers from the Worldwatch Institute and Munich Re blame deforestation and climate change from Earth warming for much of the loss. The previous one year record was $90 Billion in 1996. Source – Associated Press, November 28,1998. Using solar energy instead of fossil fuels to meet some of our energy needs reduces emissions of greenhouse gases and other pollutants. When solar energy displaces other energy sources with higher emissions levels, it produces a benefit in the form of reduced emissions of pollutants.

Example 1:A GP38-2 has a 2000 HP prime mover diesel engine.What are the horsepower ratings of the electric motors geared to the axle? [4 electric motors; 1 on each axle how much HP?]Example 2:An SD38-2 has a 2000 HP prime mover diesel engine.What are the horsepower ratings of the electric motors geared to the axle? [6 electric motors; 1 on each axle how much HP?]I know the tractive effort of the SD unit would be higher, but with 2 more motors on the axles, does it have more horsepower also?

An electric locomotive is just that - electric. A diesel locomotive is in effect a mobile power station, consisting of a large, heavy diesel engine driving an equally-large and heavy generator or alternator to provide power for what is actually an electric locomotive. For the same power output, an electric locomotive is almost half the weight. For higher speeds, higher power output is needed, meaning diesel locomotives need even-bigger engines and generators, which makes the locomotive heavier, which requires a bigger engine and so on. The fact is - with current technology - the diesel locomotive has just about reached the limit of its development with regard to speed.

I bought an old moving truck that I only want for storage. It will be parked on my off grid property. I would like to rig it to run a generator that could charge up a large bank of batteries for when my solar isn't collecting enough power. I know it can be done but I'm curious first, how to do it, and second, if it's worth doing? Thank you very much for your input.

Yea, mount up 1 or 2 more alternators, I assume you'll already have the charging electronics to go with your battery bank. The electricity from the alternators is already 12V, which is wholly usable by a battery bank. You could even set this up so that the engine automatically turns on when the amperage drops below a certain level.

Hi,I read an article and it said This implies, that more or less all customers of Esson, who own appliances dependent on permanent electricity supply, dispose of their own emergency Diesel-generator installed on their premises.I try to understand it, but I think it is grammartically wrong. I think it should be This implies that more or less all customer of Esson, whose own appliances depend on

who own appliances and whose own appliances are both correct but they mean different things. The first one is saying those people OWN (have) appliances. The second one is saying those people have their OWN appliances. The first 'own' is a verb, the second 'own' is an adjective. In the text, a simpler way of saying it is: This implies that more or less all customers of Esson, who have appliances that depend on electricity supply. .
