How much power is too much power for any one individual to handle, in your opinion?

Also, if you think that people can have any amount of power they like, you will find you are greatly mistaken.

What do Sarah Palin and Dick Cheney have in common?

admin — Fri, 13 Nov 2009 22:49:19 +0000

Besides membership in the NRA and their mutual passion for hunting, it seems like both represent ultra right-wing politics. Would Sarah Palin take over the "shadow government" and hold secret energy meetings?

They both have oil running through their veins, both are slaves to corporations, both run like girls, and both are bad for our country.

How to make my microwave work only using solar panels?

admin — Fri, 13 Nov 2009 22:49:09 +0000

Hi,
I got really interested in the whole concept of solar panels. I read a couple of articles and saw a few videos on how to convert solar energy to electricity, but what I want to know is how can I make the microwave work, only using solar panels?

What I mean, is how many Volts, Watts, Amperes or any of these do I need to make the microwaves fully functional and how many big the solar panels need to be to absord enought energy?

Thanks!

There’s a lot of important details, but the short answer is that you would need a system capable of supplying around 1000W, at 120VAC and capable of handling the current (which would be around 8A).

The specific requirements would depend on how you intend to use the microwave oven (i.e. how long its on for and how often you turn it on). Based on the usage you’d be able to come up with an idea of how many batteries you need (for storing the energy) versus how many solar panels you need (for charging the batteries).

In any case, it would be a fairly expensive way to heat food. Even if you made it cheap (i.e. so that the system could only be used occasionally), I’d guess it would cost at least $1000 for the inverter, batteries and other electronics plus another $1000 for a (relatively low power) solar panel.
If you wanted to make it more of an ‘on demand’ system, you’d be looking at a pretty high price tag.
You’d probably be better off with a solar cooker.

That being said, such a system would be able to power many other household things as well, it wouldn’t be limited to just powering microwave ovens. However economically, solar power isn’t (currently) reasonable (assuming you have access to the grid).

How to power a portable 12 volts amplifier?

admin — Tue, 27 Oct 2009 01:46:42 +0000

I need to power some computer speakers from batteries. The power supply’s output is 12 volts at 850 milliamps. The only way i can think to power this is with ten 1.2 volt rechargeable batteries, and those would only last about 2 hours. does anyone have a more practical way to power a 12 volt amplifier?

you just need to get a bigger battery
something like a tractor
or alarm system system, about 6 AH should last maybe 10 hours
you can buy those at some electronic stores

Work and energy problem?

admin — Tue, 27 Oct 2009 01:46:38 +0000

A simple pendulum has a length of 0.75 m and a bob with a mass of 0.15 kg. The bob is released from an angle of 25 degrees relative to the vertical reference line.

a) Show that the vertical height of the bob when it is released is h= L(1-cos25 )

b) What is the kinetic energy of the bob when the string is at an angle of 9 degrees?

c) What is the speed of the bob at the bottom of the wing? (Neglecting friction and the mass of the string)

Oh That’s A Toughy.

The right wing talk show goofs have been dumping on the concept of ethenol production. Why?

admin — Tue, 27 Oct 2009 01:46:36 +0000

G. Gordon Liddy this AM went on and on about how ethenol production exists only because of ‘subsidies’. He didn’t mention all of the direct and indirect subsidies to the Oil Mafia, such as this war in the middle east. Ethenol, he said uses almost as much energy to produce as it creats. But so does oil when you figure in all of the productions and distribution steps. What’s up with these guys?

being you are a lib it is doubtfull you will try and understand this.

we use 1/3 of our corn production for ethenol. the shortfall of corn raises feed prices for farmers and we pay more for meat. the amount of oil it takes to harvest, transport,distill and distribute the ethenol is about the same as it returns.

ok. lets forget all that for a moment. lets think about the vast amount of water it is going to take from the rivers and add to that the millions of tons of pesticides and fertilizers we will be putting in the ground water.

it’s just another lib idea that doesn’t work.

How do solar panels and solar energy connect?

admin — Tue, 27 Oct 2009 01:46:23 +0000

Does the solar energy hit the solar panels and creates electricity.. or what ?
Where can you put solar panels ?

SOLAR Panels?

admin — Tue, 27 Oct 2009 01:46:23 +0000

Hello from SO TX.. I would like to know if anyone out there has SOLAR PANELS on their home?
I have a 850 sq ft. house. I called Austin to a company that offers panels and installation. The cost $18,000.00, for 10 panels . The rep said we would save about 21 to 25% on our electric bill /mo. We use approximately 980 kw/mo. Our bill is around $140.00 / mo…I really don’t think that’s a good enough savings. We figure it would take 25 years to recoup our investment.
And where we live in TX it does not offer any incentives. The gov. allows you a $2000.00 tx break.

You are wasteful in your power usage. To use 980 kWh per month in such a small home is just unbelivable. Chage your lights to CFL (a 28 watt cfl is = to a 100 watt bulb) and use space heating and window A/C units. Unplug that tv set when not in use and same for other items. I found that our tv set alone uses amost 12 watts when turned off. You may say that is not much.. Well add in 4 tv sets and a couple of stereos and other items and do it for a years time. lots of waste. Our home is twice the size of yours and we only use on a heavy month about 500 kWh. With 1860 watts in solar power my last months electric bill was 19 dollars and most of that was meter fees.

18K is really about right and not bad. You will get back 2000 dollars if installed before the end of 2008 but it looks like we may be Bushed and they may not extend the tax credits.
Just have to wait for John McCain to get in office and hope he will do something about it. But McCain is running for a 3rd bush term. Hillary is not going to make it in to office an every time Obama gets under pressure he gets so scared he starts stuttering. So he will just get walked on by big oil and big money. So better do it now while you can get something back.

Just to clear something up about the cost.. If you rent power you have nothing in 30 years but if you buy a system you have a system in 30 years.

As far as new lower priced solar modules.. BS!!! Big time
BS!!!

If they can make a 3000 watt solar module for 1 cent they can sell it for the current market price. So it would take a FOOL to drop the prices. So don’t waste your time setting on your thumb waiting for this great lower price.

Ask Evergreen Solar if they lowered prices when the used OUR TAX DOLLARS to find a new way to make their panels. Well they found a cheaper way and did it and charge the same as anyone else. But that don’t stop them from braging. If they can get your money and don’t take it they woudl be fools.. Would you drop your price if people would pay the higher price? Plus someone would by them out and bring the prices back up anyway..

Is wind power generator at home really work ?

admin — Tue, 06 Oct 2009 13:32:42 +0000

I heard about wind power generator and I want to make a wind power generator to power things in my house. Although I am not sure where to find good information. I want to save money. Is there any reliable information on how to make wind power generator at home?

I made mine wind power generator and its saving me some good money I use it to power various things inside and outside my house. I found the best source of info for this at:
