  • i like the idea...we really need to conserve energy because global warming can already be felt to these days. Global warming and its horrible effects scares me.

  • "utilising a technology you've never seen before!" Really? Robert Stirling 1816.

  • Interesting how a company that is pro-"free energy" has the Edison name. Spare a thought for Nikola Tesla. If you don't know who he was then you should find out. Seriously! Thomas Edison electrocuted elephants and stray dogs in front of the public in order to discredit Tesla's AC current, that we all depend upon today. Tesla knew about free energy and harnessed it, but his eventual association with JP Morgan lead to his assassination as "free energy" can't be metered.....

  • If they have wheels, they can move around everywhere avoiding cloudy areas. Wind power generators may also have wheels and move around to take in wind energy. Water stream are only fluctuating around seasons, water power turbine and wind power turbines can be combined as well and they might be able to move around using steel cables to relocate to high volume stream locations.

  • Solar as a horrible capacity factor. Your little 2.5kW unit may sound great until you realize its capacity factor is less then 20 percent. What does this mean? Basically you are only going to reach 2.5KW 20 percent of the time. Nuclear on the other hand has a 90 percent capacity factor.

  • @Allante715 20% solar + 70% nuclear + 10% coal = 20% improvement compared to nothing. You don't run the moment you were born. You first crawl, walk, run and finally learn how to jump.

  • Holy crappers, SE's are becoming big business!

    I shall build a company to deliver the power of Stirling engines to the masses! :D

  • I'd luv to kiss my local power company "Good Bye" or at least reduce my purchases from them.

  • Thanks!

    I wonder if there is a comparison between stirling and panels?

  • I've never heard of Stirling engines being efficient. I wonder how they did it, and I wonder if there will be wear problems.

  • @sjh7132 All heat engines have a maximum efficiency based off of the temperature difference on each side of the engine. They can never reach 100% but they are extremely efficient when you consider that you are converting heat to mechanical energy. I think they reached ~70% efficiency from these systems a few years ago on a clear winter day.

  • we're building the prototypes for the power conversion. You will see the full scale production in a very short time.

  • how about a 2.5 kw unit in your back yard ?no middleman.

  • @spaceshipearth999 you can build this your self. you just need access to a machine shop and some fab skills. we are building one right now, but were making a stirling cooling cycle fridge.

  • hi 565Customz

    that comment was a long time ago , since then i have watched a few hundred videos related to design and construction. every backyard or roof could have one.

  • @spaceshipearth999 good to see you left the dark side. lol

  • gotta love the internet. . concentrated photovoltaics looks good too, quieter, also steam turbine.turning axial flux generator ,woodgas, etc.

  • @spaceshipearth999 PVs are good. especially the concentrated, but how long are they gonna last, and how expensive and hard to get are they? if the world was gonna end tomorrow, i know for a fact i could build one of these with the machinery i have...thats comforting. lol.

  • hey customz

    any end of world scenario includes the earth clouding over for a year .. wind will function but solar people are screwed. lol.

    multiple options are best.

  • @spaceshipearth999 lol...in that case, im sure i can find enough fuel, wood, newspaper, lumber, gas, diesal, kerosone, or whatever...to drive my stirling until the sun comes back out! lol

    stirling wins!!! :D

    no but serisouly, i think stirling is the best option, until PV reachs 50%, im not buying.

  • you right. stirling engine cane be multi heat source driven. it is an indispensible off grid self sufficiency device. i like concept of tilting mirror array down at night to connect stirling with wood gasifier or other night time heat source for stirling to keep working for you.

  • @spaceshipearth999 i was thinking using a waste heat tube wrapped around the engine...pump liquid down that tube slowly and heat a lagoon (with cow poo...lol) that heat speeds up the anerobic process and you get methane to burn...you just would have to be careful to take only WASTE heat...not take any from power production.

  • @spaceshipearth999 or just make the lagoon the heat exchanger...

    lol the worlds first cowpoo heat exchanger.

  • We agree to buy a middle man position.. now the customers can still get F'ed in the A.

  • Amazing, this report appeared 2 years ago today. Since then, they haven't even begun to break ground at either site due to the obscene bureaucracy in Sacramento, and our illustrious Senator Feinstein, who has vowed to kill both projects at the behest of her masters at the Sierra Club. Until the clowns in our government recognize that the economic health of our state and our country are more important than flat-tailed lizards, turtles and bugs we will never solve global warming.

  • Even if you used a large portion of the Southwestern area for solar power, it would be risky to depend on it for power because what if a natural disaster damaged the equipment? It would be interesting though in that it would create a ton of maintenance jobs.

  • I understand that each parabolic dish and a sterling generator produces 25KWh. What would be the cost of purchasing and installing just ONE of these? Someone please respond...

  • are those mirrors convex at all?

  • I think this is top! Lets get the 100 square miles of desert covered now. Polutant free energy is the way forward. More solar and stirling engines please!!

  • Visual pollution? Waste of space? Transmission loss?

  • @kieranmullen2 visual? who the fuk cares about a bunch of dishes in the middle of the desert? waste of space? you gonna build a house in the middle of the desert? transmission loss? new technologies using undergroud super cooled lines increases power transmission 400%

  • Only they talking talking and talking but they doing everything so that it doesn't happen this way...

  • Poster said "If true, we may be able to kiss nuclear power plants good bye." in description. What?? Nuclear power is GREAT, the newest plant we have operational at the moment is from the early 70's and it's virtually impossible to make melt down by any terrorist act or otherwise. Waste is nearly nothing and we have 50 billion dollar Yukka Mountain built for storing the rods. What we need to get rid of is oil and coal plants that throw crap into the air and which use non-renewable resources.

  • waste is nearly nothing? NOTHING but radioactive moron!

  • Radioactive moron? They're able to recycle rods now. Rods are tiny also, we have a 40 billion dollar facility to place them in. It's a much better concept then pumping shitloads of nasty fumes into the sky you twat.

  • uh hello all the radiation produced by the power plant is absorbed by the concrete shell that surrounds it duh, plus jettisoning the waste into space is a viable alternative as well can you do that with all the co2 created by fossil fuel poqer plants?

  • um, there is more radioactivity in earth's core. How do you think rocks turn into molten lava?

  • Two probs:

    1. Risk transfer: operator only needs insurance coverage of ~$M110, and feds (us) cover up to $M650. Then, you're on your own.

    2. Waste heat. Huge with any nukes, since they are saturated-steam plants. Kills efficiency, and plays hell with LP turbine blades.

  • its funny , you can't buy a stirling engine, except for beer cans and toy models thats all I see here , this sounds good but why cant you buy one

  • You can buy office toys as well but my motors will be the first high heat motors available for kits or assembled eventually. Production of parts of good quality is tough and that is why you do not see as many for sale. These in video could cost into the hurdreds of thousands each.

  • It will be possible to buy one in the near future. Check out a company called Infinia. The make dish type sterling power generators like these ones but better looking. The produce optimally 3kw per day.

  • isnt energy like money in the bank... cheap energy is saves you 25cents expensive energy saves you a penny ...but either way shouldnt you end up on the plus side?

  • ive never really understood the concept of expensive energy... shouldn't energy always be on the plus side im mean if its not enrgy creating is energy consuming...so shouldn't all energy put you on us on the plus side?

  • has anyone thought about placing the stirling solar power engines along side the wind genrators.. you can double the output with the same amount of square footage area required to install them... amybe the blades will get in the way of the sun rays

  • I think wind machines would block sun, but I thought of putting them around oil pumps down around Artisia NM. Roads are there allready, and so is a wire to each pump. I think PV is allready the winner as far as ecomomy though.

  • it wouldnt block it by that much

  • their website news page hasn't been updated since dec 2006. I guess things didn't work out. I emailed them but the email bounced (not deliverable). oh well!

  • sould be 50% not 20%

  • I found a DIY project for a parabolic solar reflector that anyone (even I) can build. Ingenious design, too. Go to instructables "dotcom" and search for "multifacet" and "parabolic". Good luck.

  • awesome! i could use this for a project!!! ty for posting this!!!

  • edison??????

  • Can't wait for a natural disaster to happen

    i.e. hailstorm, tornado, earthquake haha

    what they should be doing is building a dyson sphere haha

  • I want one of those in my yard.

  • NO WAKE UP THEY SHOULD PERIPHERALLY HEAT WATER DURING DAY THAT IS ECO-PUMPED AROUND THE HOT END OF THE STIRLINGS FOR REDUCED OUTPUT GAIN. NO RETRACTING POWER LOSS EITHER THAT TAKES CARE OF HOT WATER CIRC. KEVLAR LINED TANKS TO RETAIN HEATED DAY WATER?

    Such a cool vid,

  • I agree with luvofcountry.

    @SCTV there really is no problem to do this in your garden. In my country NEC (National Electricity Company) is legally obliged to buy 100% of my production if it's solar, water, wing or geothermal generated) and on a superbly good prices(for exapmle 0.50$ for

    kW/h solar energy)

    I read NASA has built cars with Stirling engine.

    I'm also happy that USA finally signed the Kyoto Protocol which leaded to that kind of projects.

  • @jbphot0

    Stirling engines are nothing like car engines at all. Get your facts straight

  • I would worry that if these collectors were placed in a single geographic area, supplying power to most of the country, they would become tempting targets of terrorists to cripple the country. Also, a large array of that type might be vulnerable to corporate sabotage in order to drive up prices. *Anyone else see the PBS docu about Enron's "rolling blackouts" in order to drive up prices to pay for their hidden debt? Very interesting.

    Any thoughts?

  • Sterling engines are like car engines, too many moving parts, too much service required a 100 MW project would be a maintenance nightmare. Although the thermal storage is good for peak shaving.

    Stick to concentrating photovoltaics!

  • The Stirling engine here has been updated for the higher demands being placed on it so of course it has more parts. If you want simple then you can make one from a soda can with some bits of rubber and sticks but it wont produce any electricity. This improved engine is encouraging to see, I just hope we see more in the future.

  • wow, i didn't realize i had started something. The sterling engine in this video, built by SES is what i was referring to. They are still having reliability problems. Mean time between failure was reported at 42 hrs. They have not been proven in the industry yet.

  • That being said, I hope they improve quickly because they've landed some big contracts with Sun Edison and PG&E in California. If they fail to deliver, it helps PV, but looks bad for the whole industry. I want every reliable technology that makes power from the sun to succeed! SES just has a few problems to work out before they are viable according to the majority of the PV industry.

  • I'm not sure where you're getting your misinformation, but you may want to avoid that source in the future. This device is still under joint development between SES, Sandia National Labs, and Boeing. They're only in phase two and have already achieved >400 hours MTBF. While still not great, it's just a matter of materials and engineering to remedy this.

  • "it's just a matter of materials and engineering to remedy this"

    I could say the same thing about desktop fusion.

    I am looking for a single example of any commercially successful, sustained application of Stirling engine power. I can't find it. The world is full of museum pieces that sit and spin. Why, after 200 years, is there no real-life examples of a man taking one of these and doing real work with it?

    Don't get me wrong, I'm all for any forms of alt. energy that we can benefit from.

  • Suppression?

  • the fan running off the heat on top of a wood stove is a good use of sterling. directly coupled to the source application. Commercially successful?

  • Sadly, it is far from commercially successful.

    "Major reliability problems with ...Stirling engine included [too numerous too mention]. That means that on average once every 40 hours a problem of some type required shut down and maintenance. Nearly continuous maintenance was necessary to keep the system "available" to generate electricity."

    From Barry Butler, a PhD expert in Stirling solar technology. google kdfullerblogspot and go to 4/17/08

  • Swedish submarines run on stirling engines (for silence). They are also used as commercial

    cryocoolers. (Stirling engines, not the subs...)

  • Thanks for this excellent post! These folk are hard-nosed business men. They don't take risks and they do their sums. Watch their share price climb over the years. Bravo!

  • its about time they did this

  • if i put a dish in my garden to power my house and nab ours.... they will have to shoot me for before they will get one cent tax for using the FREE SUN...either that or build a giant umbrella over my DISH

  • Lol you have been watching too much Simpsons...Mr Burns

  • I'm not the only one then... but seriously, if I don't sell energy to make a profit..... NO fucking tax..... easy hey?

  • Somebody possesss more given technician? Generation in alternating chain or continuous AC or DC? Somebody knows to inform on equipment as this of small transport to feed house and small edificções? I ja heard to speak of one of small called transport "sunmachine" in Germany.

  • I know shadows have got to be considered, but couldn't the dishes be placed closer together to allow more to be placed on the same amount of land?

  • the shadow cast will change as the earth follows it's orbit around the sun. so it well may appear to be to far spread it keeps the shadows to a 0.000% only a .1% in production efficiency would equate to great losses.also energy production is not linear.

    also for everyone else, the fed goverment as made great efforts to undermine these technologies, and have taxed other plan like this into the scrap heap.

  • What a GIANT load of CRAP! Please spare us the moronic conspiracies. The *FACTS* are that SANDIA NATIONAL LABS are *partners* along with Boeing in the development of this technology. Tax dollars WELL spent. If you have evidence to the contrary, then CITE YOUR SOURCES!

  • maybe they put it that way to give enough space in case they need to repair one of those dishes

  • These kinds of solar concentrator dishes are becoming common around the world, each produces a max of 22-25 kW.

    Sometimes they use photovoltaics at the focal point instead of Stirling engines.

  • What....do you expect free electricity do you? Of course it will be taxed, how do you think its paid for dipshit?

  • I have no problem paying for my energy usage, but to overpay because of an offset tax is ridiculous, I believe this was the point the last post was trying to make...

  • Or the Republiscum find a way to bury it all together. Given the choice, I'd rather *pay* for a choice rather than be fucked out of the option.

  • This is really one of the most exciting and brilliant ideas in alternate energy to come along in a while. I never thought the sterling engine would be anything other than a toy.
