Renewable Energy At Home

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

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.

What is the amount of solar energy required to drive a 250 pound cart with a 250 pound person 10 miles? How many square feet of recharged paneling would be required?

If you are willing to go slowly enough, all you need from the solar panel is enough to overcome static friction to get the cart started.

I do know that a cyclist cruising along at a moderate speed (say, 10 miles an hour) is expending about 1/10 horsepower. That’s 80 watts. So on flat ground, a 100-watt panel push them over the 10 miles in an hour. Such a panel, if square, would be 2 to 2.5 feet on a side, if made with typical contemporary materials. If the terrain is more than gently rolling hills, more power would be needed.

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.

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).

Geothermal energy is often the great hope of renewable energy as it can be continuously and reliably produced 24/7. While it it has the best potential, it is very limited geographically. The best geothermal resources are in Alaska and California, and the best potential resources are west of the Rockies. How do we overcome the geographic limitations of geothermal energy?

The simple answer to your question is: ‘dig deeper in the ground.’ There are several companies out there at present that are willing to install geothermal energy suppies into the home. I live in England and I have had pumps installed in my gym. I save hundreds of pounds each year in electricity bills. Unfortunately I can only source my knowledge onto the e-book that I purchased but if you have any more questions about this please email me and I will answer the question to the best of my ability. Hope this helps.

Which major would be best for a job in cleantech companies or any other alternative energy businesses. I would guess some sort of engineering but I don’t specifically know which type of engineering. Thanks.

The best major would be Environmental Engineering, which deals with the environment, natural resources, consumerism, etc. Your second bet is Chemical Engineering, which has to do with detailed analysis of harmful chemicals, how to get rid of them, etc.

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

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.

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.
