Alternative Energy Systems

[kevinmoore001]

Happy to see you are promoting Renewable energy technologies! I keep most of my Renewable energy technology work over at flickr Dot Com

search: kevinmoore001and look in my Sustainable energy + Hydrogen economy set

#WTH is this, a music video?

ha ha at 2:40, certainly a solution would be not to use energy at all and live like back in the all days when there was no electricity, everything would be more natural. But most people won't willing to do that of course. So, go renewable energies!

The Zap X claims at 2.17 are wildly optimistic. If you look at ZAP's website, they don't even list this as a product, just a bunch of 3-wheelers. I've seen them - nothing to get excited about. The claimed 350 mile range & 10 min. charge time? Assuming 4 kWH required per mile (as Tesla), then need 1,400 kWH for 350 mls. Assuming battery is ~ 250v., then charging current for 10 mins. would have to be (wait for it) ....... 33,600 Amps. You would need your own power station. Get real, please!

250V AC? LOL

[Gruntol5]

Why do you ask "250V AC?" A battery produces DC - I'm sure you know that. If you don't like the idea of a 250V battery (there's no reason not to) then do the calculation for a 100V battery. The charging current would need to be 2.5X greater - ~84,000 Amps. If the internal resistance of the battery pack was only 0.001 ohms, the heating effect (I squared X R) is over 7 megawatts - enough to heat a skyscraper.

[cortkatanakx1q]

I know. Batery is DC only. You still write AC symbol. I think bateries are bad. I do not like them. But if I wanted a new car in near future, I would buy something like Tesla Sedan. Not because ecology but economy.

[Gruntol5]

The symbol " ~" is the scientific notation for "approximately." I hope that makes things clear.

I'm sorry you don't like batteries - I don't know what we would do without them!

[cortkatanakx1q]

I don't know how it is in USA. But if you write "~250V" it means "250V AC". Bateries are the same junk as oil IMO. And if you want to charge maybe 250V accumulator it is posible to have some electronic cirquit which change series wiring to series and parallel combination. Charging accumulator with series wiring isn't good.

*tut* why dont you just use magnetic pull?

[chargermopar]

As for me I will be driving a Diesel pickup running on palm oil and algae oil gathered from local sources.

To people who talk about the cost of a hydrogen infrastructure I have this to say:

When someone first suggested electric lighting, people said 'why have wires in our walls when we have candles?'

Of course it costs a lot more than candles to put those wires in our walls, and it is a lot more complicated, but could anyone go back to candles now?

[AppleSouffle]

That's a good point Timmy Tabs. I remember my Dad said that when light bulbs were first becoming popular, many people said they would never have to sleep again because inside their houses, it would always look like day light.

When Benjamin Franklin invented the lightning rod, there was widespread opposition because many people said it was against the will of God. Then lightning his a church in Italy that was full of ammunition. Boom baby! That changed many people's minds.

Model U: Hydrogen Internal Combustion

The Ford Model U Concept is propelled by an internal combustion engine (ICE) that's optimized to run on hydrogen fuel instead of gasoline. The engine is supercharged and intercooled for maximum efficiency, power, and range. Its emission of all pollutants, including carbon dioxide, is nearly zero, and the engine is up to 25 percent more fuel-efficient than a typical gasoline engine.

dont be conned by the promise of clean air with hydrogen,the large majority of the worlds hydrogen comes from processes which CREATE GREENHOUSE GASSES! energy is only as clean as the means used to create it.

also in order to extract it you need more energy that you would get from the hydrogen you extract!

look up 'the hydrogen hoax' by robert zubrain for the details. peace, and please do not be conned by the hydrogen SCAM!!

[EllasPapa]

Not if you use solar or wind to create the hydrogen, just a thought not sure if solar can do it.

[ChemicalMikeUK]

like i said,quote; "the large MAJORITY of the worlds hydrogen comes from processes which create greenhouse gasses" if you bothered to read the article you would see exactly what i am talking about.using the other method which you are referring to is called 'electrolysis' this method IS clean and does NOT create greenhouse gasses.HOWEVER,you have to produce elctricity and amperage for this to happen.more energy is used to extract the H2 than the H2 produced will provide. kinda silly eh? peace

[Maxdwolf]

Energy is lost in any system. There is no 100% efficiency. One has to look at all the various factors. Not just energy efficiency but also costs and applicability to ones needs. I don't think hydrogen is the way to go, but let's not get too simplistic about it.

[Maxdwolf]

People are misled in thinking of hydrogen as an energy source rather than and energy storage device. But this and electric vehicles both allow freedom of choice in the original energy source.

All hail the electric car!
