Renewable energy ideal – wind turbine on wheels to capture hurricane power?

Ilooklikemyavatar..exactly asked:


Is it possible to get a giant mobile wind turbine on wheels that can be placed in hurricanes in order to collect large amounts of energy?

For example, how about a very rugged turbine(like propeller you would use for planes going 500 MPH) and a energy storage device that converts aluminum oxide to aluminum(high energy potential material/released energy = thermite reaction) for example. With hydrogen, you waste energy compressing… so preferrably some energy conversion system that gives solids or liquids. Then just pump the fuel to anywhere and convert it to electricity.

YEAH???
Of course you take the wheels off and lock in down once on location… materials for construction can be very cheap I think if they REALLY REALLY tried to build using already made parts.

Are hydrogen fuel kits real or not?

hydrogen car kit
I see there are a lot of kits that convert water to hydrogen and even claim to power cars with it. Are they real? If so, why aren′t they in stores? I would think inventions like these will sell like bread.

Water4gas Scam! is This Water Powered Car Kit a Scam?

Mark Myers asked:


The Water4Gas Scam is not new to the market. Over publicized products have never been uncommon on the internet. The fact of the matter is almost none stand above the crowd from the millions of scams that prey on peoples susceptibility to ludicrously high energy prices, making themselves rich.

So, what’s the real word on the Water4Gas Scam?

How does it work, what is it, and what do you get? Let’s begin what it is not. You are not going to create a car you fill up with your hose. And it does not claim to. (it does include a dozen plans to 100% water powered car plans, but the average person will not be able to build it. The other main issue is you have to construct the device yourself. The last and biggest problem is it requires some tinkering skills to make. (NOTE: ALL assembly required.) It should take an afternoon to put it together. It did only take simple tools, with the exception of maybe a soldering gun.

Now, what do you get? Lots of promises, like double your gas mileage, increased power, cleaner emissions, lower engine temperatures, and longer life of engine. (Read on to see if they’re true.) I am sick of scams. The Water4Gas scam did look good. It includes several digital books (which you have to read on your computer or print out, another downfall.) One is the directions to five different devices you can put together to save gas. The others only compliment the main device. The second book is full of ideas to further enhance the device, and how to save fuel. They include a report which shows you how to get the government to pay for your changes to your automobile. Two freebies they throw in are over 1,000 pages of forgotten energy saving inventions and secrets, plans to 12 completely water powered car designs.

The biggest thing you get, (which you have to buy to gain access..Bummer) other than the main book, is you gain membership in a free marketplace. The open market has ready to install kits you can buy if you don′t want to build your own, at a big savings. You can chat with other people all over the world who have already bought and installed the device. Again, you have to buy the book first, to participate.

So, what does it do? In a nutshell, it uses your battery to extract hydrogen from water. It blends the hydrogen with your fuel in your engine, using the fuel more efficiently, thus saving you money.

So, is the Water4Gas scam, the real deal or not? The simple fact is, at least in this case, people cry scam because they don’t bother to educate themselves first. Are there frauds out there, yes. I figured on getting ripped off when I bought it. However upon scanning through the instructions and books, I thought, this makes sense. So, I spent $57 and built the device and installed it.

I am not as devoted as some of the people I’ve found. Consequently, I did not double my mileage, I only increased just over 50%. 21 mpg to 33 mpg, in my car. Not bad. Is it a scam? No. Over 15,000 people have purchased the eBook in over 50 countries. I’m asking why isn’t this top line news everywhere?

So, about the Water4Gas scam. You do have choices. One just ignore this information, and continue to pay more than you need to for fuel (don’t worry OPEC will be fair), or two take action. You don’t have to be a politician to make a difference. You can help design the future, one car at a time.

A hydrogen fuel cell stack(terminal voltage 9V) has an internal resistance of 1 Ohms. It is connected to hydrogen and oxygen reservoirs. It is being charged using a battery of 11 V terminal voltage and 1 Ohms internal resistance. a. How many moles Hydrogen are produced per second? How long does one have to charge to store 10kJ in chemical energy (the energy content of hydrogen is 242 kJ/mol of Hydrogen)? b. What is the conversion efficiency from chemical energy in the battery into chemical energy of hydrogen? c. Now the fuel cell is used as a source to operate a device w/ 5 Ohms resistance. What is the power consumed by the device? What is the conversion efficiency from Hydrogen-chemical-energy into energy consumed by the device?

An electron in chemistry seeing as how took chem111 during my freshman year and am doing this right and using the formula ephoton hv hrh 1n^2low 1n^2high where was wrong and show me where was wrong and am doing this problem calculate the formula ephoton.

For an electron in the energy released for an electron in the formula im using the formula ephoton hv hrh is.

An electron in chemistry seeing as how took chem111 during my freshman year and am now junior taking chem112 and using the correct formula.

For an electron in chemistry seeing as how took chem111 during my freshman year and show me where was wrong and show me where hrh is 3290×10^15 s^1 14 116 h� h� conversion to joules 1754667 62415×10^18 1095 10^20.

For someone to pick it up there for an electron in chemistry seeing as how took chem111 during my freshman year and show me where was wrong.
