Technology Review: Solar Power at Half the Cost

Technology Review: Solar Power at Half the Cost
“A new mechanism for focusing light on small areas of photovoltaic material could make solar power in residential and commercial applications cheaper than electricity from the grid in most markets in the next few years. Initial systems, which can be made at half the cost of conventional solar panels, are set to start shipping later this year, says Brad Hines, CTO and founder of Soliant Energy, a startup based in Pasadena, CA, that has developed the new modules.

Concentrating sunlight with mirrors or lenses on a small area cuts the costs of solar power in part by reducing the amount of expensive photovoltaic material needed. But while concentrated solar photovoltaic systems are attractive for large-scale, ground-based solar farms for utilities, conventional designs are difficult to mount on rooftops, where most residential and commercial customers have space for solar panels. The systems are typically large and heavy, and they’re mounted on posts so that they can move to track the sun, which makes them more vulnerable to gusts of wind than ordinary flat solar panels are.

Soliant has designed a solar concentrator that tracks the sun throughout the day but is lighter and not pole-mounted. The system fits in a rectangular frame and is mounted to the roof with the same hardware that’s used for conventional flat solar panels. Yet the devices will likely cost half as much as a conventional solar panel, says Hines. A second-generation design, which concentrates light more and uses better photovoltaics, could cost a quarter as much. He says that a more advanced design should be ready by 2010.

The Soliant design combines both lenses and mirrors to create a more compact system. Each module is made of rows of aluminum troughs, each about the width and depth of a gutter. These troughs are mounted inside a rectangular frame and can tilt in unison from side to side to follow the sun. Each trough is enclosed on top with a clear acrylic lid. Inside each trough, a strip of silicon photovoltaic material runs along the bottom. As light enters, some of it reflects off the inside surface of the trough and reaches the strip of silicon. The rest of the incoming light is focused on the strip by a lens incorporated into the acrylic lid.”

Lots more in this article from the MIT Technology review (thanks to Fraser Clarke’s newsletter for the tip). I’m not a big believer in domestic micro-generation from PV unless you live in a hot desert because PV technology is inefficient with poor ROI. Investing in insulation is a MUCH better option – PV is essentially a rich boys toy in most cases, though it’s good for hot water and underfloor heating. But it’s good to see that the technology is moving on. As a cursory look at the red herring will tell you there is VAST VC investment in PV going on right now. We’ll have to see whether it pans out as a domestic solution – unlike wind, which for most people relies on economies of scale (and tall windmills) to be worth doing. I.e., big wind farms.

Nevertheless I would very much like a rich boys toy in the shape of some PV panels (we won’t have room – or sufficient wind speed – for a windmill) and I am tracking this space closely.

STREAMIZM! dubstep saved my life archives now up!!!

STREAMIZM!

Boomnoise (and friends) put a massive effort into the first big dubstep forum event, even to the extent of getting it streamed live – now that’s professional! And from all accounts it WENT OFF. But! You can judge for yourself. Streamizm is putting the archives up ALREADY! Downloads soon. The link above is for the MASSIVE Reso Vs Rusko set but just go to streamizm.com for all the rest (bar Mala, for obvious reasons, and some of Shackleton).

Wicked stuff. Between this, the FWD sets, and (ahem) my vids of Youngsta we have lots of fresh live dubstep coming through online.

As John Eden is wont to say, even if dubstep isn’t that good musically*, the people are amazing!

* obviously I think dubstep is the best scene in the world right now…

FWD JME Birthday Bash recordings

Surely you haven’t missed this… if you have, it’s amazing… big fat chunks of all the key sets from the night. I am overjoyed to be able to catch this since I couldn’t make it – amazingly I don’t think John Eden has posted a review to his blog yet. Naturally I like the Loefah one best but this is absolutely historic… top quality dubstep with top quality grime MCs over the top. Heaven-sent.

Soul Jazz Sampler review

Kode 9: Magnetic City – who’d have thought the nine would have come out with a deep house-inflected number? Downtempo, well, down to house speeds anyway, clicking off-beat 4×4 hats, only the 3:2 ragga-style kick deviating from the Basic Channel rhythm. The melodica Steve talked about in a recent interview is present in full effect and invites comparison less with Augusto Pablo than with, bizarrely, the Specials. Heaps of echo, an immersive bassline, it’s one HELL of a good record.

Digital Mystikz: Wait – and no, this is not another funked-up Mala banger, or a massive Coki wobbler, but something else again, a really sweet arm-chair dub that would nonetheless be a fantastic mid-set chiller. We are talking extremely finely judged digidub with a low end that is articulate rather than deliberately stiff and subtly modulated descending melody lines. In fact if anything this is the bastard offspring of Mala’s Cays Crays remix, albeit instrumental. It’s really very good indeed, but it’s really much too short and is crying out for some vocalist-versus-MC action over the top. If thats sounds like I’m saying that not enough happens then that’ not quite true for subtlety is the order of the day here.

Overall an excellent 12 and it makes me wonder if I should re-edit the soon-come dubstep sufferah 3 to include one or both of them.

Youngsta at Dark Crystal, Sheffield, 3-5-2007

I’m not sure I can put into words how good Youngsta and Task were last Thursday. It was a DJ set that simultaneously displayed such awesome power, evil groove and monumental beauty that it was impossible to experience it without an over powering sense of transcendence.

Everything good that Youngsta is famous for was fully present and correct; nothing of the errors Youngsta occasionally displays was in evidence. The technical skill of mixing and transformational EQ was spellbinding, and as ever the selection was not just unique – much of his arsenal of exclusives was deployed – but impeccable: the set unfolded in every sonic dimension to assume ziggurat-like proportions. Dramatic teasers of hits such as Cays Crays, Crunked Up (sadly not present in doubled form) and even Midnight Request Line were seductively dropped into the mix.

Yet at no point did Youngsta descend into faux-techno formalism or blank, funk-less industrial wobble. This is not to say that wobble, industrial tones or techno stylings were not in evidence – they were, and abundantly. What was different was that these were simply elements of the palette with which Youngsta has re-painted garage. For Sheffield is a difficult city for dubstep stars to play in, but an excellent place to see them. Ours is a small city, with a small scene, and few core fans, and therefore it is a punishingly hard city to win over; but as a result dubstep artists have to raise their game to make a night worthwhile. I got the impression Task at least was unimpressed with both the turnout, which I would guess was 200 (though I’d be happy to be proved wrong), and the response; compared with DMZ or FWD the DQ bar must be something of a comedown. What was worse was the system which, due to a visitation by Health and Safety earlier in the evening, was not operating at the peak of its probably fairly limited capacity. Sound was hi-fi-clear and well extended, but there was not a hint of chest rattle. It was a sound to listen to and dance to, but not a sound in which one could take up residence. Bass was boosted heavily ten minutes into Youngsta’s set (as evidenced on the tape by a sudden rush of distortion) which boosted the crowd’s energy nicely.

Even so the people who had made the effort to attend were surprisingly up for it, and the crowd was well mixed too. I had the privilege of going with renowned dubstep promoters the c90 crew, , who are some of the most dedicated dubstep soldiers in the country, but there were plenty of less committed punters who were going for it. Prior to Youngsta, Distinction was really on too early to be able to do anything more than provide background noise for early drinkers, but Rogue State had a fair sized midnight crowd that they managed to utterly make their own. Frankly I didn’t expect much but now I predict great things.

They play a very personal style of dubstep, delivering a set that was maybe 80% their own tunes, creating a delicious variant of 4 x 4 techno-infused dubstep that was very danceable indeed. The crew’s DJing style was confident and had every reason to be; I will definitely be going back for more. They have a record out on R8 records that I need to track down – Alex Deadman, who helped promote the night and is involved in R8, was raving to me about how good it was a couple of weeks ago. I should have paid more attention. I’ve expressed doubts about Peveralist’s work before, but not only did Rogue State manage to turn his The Grind into something spookily funky, but they were easily able to match it with their own productions. Anyone taken with the minimal / techno-influenced side of Bristol dubstep should check out Rogue State immediately. I’d also draw something of a parallel with Cloaks, who seem to be criminally under-appreciated if not almost completely unknown, despite enjoying success on the Werk label, I must write about them actually.

They also dropped TimeBlind’s excellent Copy Copy (to which EP I gave a mixed review a few months back), so if you perceive a certain Hermetic clicky electronicism to their sound, you’d be right, but by god they can bang a party. I notice the redoubtable Foresnics is all over Rogue State like a cheap suit on his (very good) May mixtape – big up the bad man of the monthly mix. Rogue State even managed to rise above the unimpressive MCs, who were I’m afraid nowhere near as good as those usually fielded by Junglist Alliance.

At best they were a bit nondescript and at worst, especially in the climactic final ten minutes of Youngsta’s set, they were actively irritating. Certainly they were a distraction D1 whose set started promisingly with some delicious hazy string driven garage but which was sabotaged by technical problems – it looked like the right hand needle was jumping all over the place. He advanced too rapidly into plodding halfstep for my taste, but by then I was finished anyway.

Youngsta at Black Market

So the night belonged to Youngsta, but then we expected that to be the case.frmthe first primal, open-ended, effortlessly funky cut, which was expertly doubled, Youngsta was utterly in control of the dance.

The over-powering and entirely unexpected product of Youngsta’s expert transformational EQ and overwhelming selection was that he took you to a very similar place as Mala, but by a completely different route. For Mala famously delivers what is effectively roots music – spiritually-founded, humanistic, yet other-worldly sonic medicine that successfully attempts to elevate the soul – even among people who don’t believe they even have a soul. Mala’s sound is, above all else, one of organic warmth – even when delivering his most punishing, hurting, industrial steppers, there is an abiding presence of sentiment that overflows through the speakers. Youngsta’s artistic is quite different. As Task so frequently and effectively warned us, Youngsta’s aim is to “bring the coldness”. His desire is to explore the texture of sound, unencumbered by any attempt to invoke obvious human feeling – yet paradoxically, that sense of reserve, of emotional humility, serves only to magnify the emotional impact of his sets. Never mind the fact that at around the 20 minute mark he dropped the most monstrous Coki wobbler yet made, cut together with some vast, menstrual electro war machine, a combination that was quite simply the most devastating application of bass science conceivable in mid 2007. That technical perfection is irrelevant compared to the overall pattern of his selection, which combines to take you to a place that is simultaneously utterly transcendent of everyday consciousness, and nakedly rooted in human experience. And, of course, a fantastic night out. Listening back to the tape I am reminded of nothing more than prime period On-U sound, but he was in so many ways better. There can be no higher praise. Youngsta slew dem.

Grievous Angel presents Blogariddims 21: Fusion Dub. A mix of Miles Davis-inspired jazz, funk and soul, in dub

This time last year I was waaaaay deep into a series of pilgrimages deep into dubstep, a process that is still ongoing, though not as spiritually all-encompassing as it was. And part of my response to the influx of dubstep vibrations that have been flowing into me since 2005 has been a re-connection with deep dub sounds of… Miles Davis. My connection with Miles has always crossed over with dub, electronics and industrial. I got heavily into Miles, especially the electric period but also the Gil Evans orchestral period, at the same time as I got into Cabaret Voltaire – when I was 13, almost 14. It was only a year or so later that I realised how much of an influence he was on Richard Kirk and Stephen Malinder; all I knew was that the sonics and spaces of 2 X 45 were identical to On the Corner. In the same way as the threads connecting from the Cabs to acid to ardkore and thence to dubstep are obvious, for me, the thematic connection from Miles to dubstep is also clear, but it’s more a matter of influence than direct connection.

So it was that when I was asked to do a solo outing in the brilliant Blogariddims series, I almost immediately decided to go on a voyage into Miles – in dub. I was going to include a lot of other fusion artists, but not much that I have in that genre really made the grade, so instead I threw in some of the soul and funk that influenced Miles in this period. And naturally, I used as my raw material much of Bill Laswell’s fabulous Panthalassa CD, which adds a layer of dub and re-edits to Miles’ originals. I simply re-edited and re-dubbed what Laswell did. All in all it’s an appropriate way for Blogariddims series to greet Beltane. I hope you enjoy it.

Liner notes:

0:00 Miles Davis: Bitches Brew intro
This snippet is so recognisable – those sharp parps are the perfect signal to wake up for the mix.

0:59: Miles Davis: Agharta Prelude Dub
Sheer, unadulterated, slow motion funk bliss. A dub of one of the tracks on Panthalassa, the original is from the Agharta album, which was recorded live at the Osaka Festival Hall in Japan on February 1, 1975. A lot of critics think is one of Davis‘ two greatest electric live records alongside Pangaea (which were both recorded the same day – Agharta in the afternoon and Pangaea in the evening). The band has its roots in the seminal group assembled for On the Corner. Saxophonist is Sonny Fortune, guitarists Pete Cosey (lead’n’headfuck feedback) and Reggie Lucas (rhythm), bassist Michael Henderson, drummer Al Foster, and percussionist James Mtume. Bill Laswell edited “Prelude,” down from over a half-hour and I took it down to five minutes so all you have here is pure funk jazz fire.

5:06: Miles Davis: Miles Runs the Voodoo Down (Edit)
Probably my favourite cut off Bitches Brew, this, at least it is now it’s had a bit of vigorous pruning. The album was recorded over three August days in 1869, right after the Woodstock Festival. Miles famously would assemble musicians at short notice, forcing them to think on their feet with minimal guidance – which must have been a total head-fuck. You can tell how the band are right on the edge of mapped territory on this tune, but they’re locked tight. It starts off all gorgeously loping, before slowly lifting off into heavy, fat jazz that almost has dubstep’s “wobble” in the low end. I took out a lot of the free jazz bleating in the middle and made sure there was plenty of Miles’ red hot but laid back groove, and even so we fit atonal jazz funk gold at around 10:39.

12:19: Parliament: Dr Funkenstein (Live) (edit)
God, I love Parliament. This is probably the best track off 1977’s Parliament Earth Tour album. It’s just a fat, minimal, drum and bass funk locked groove. The recording isn’t that hot but the playing is unbelievable so I slashed it
down from its original 15 minutes and dubbed the fuck out of it. The end of it is very Apocalypse Now, the scene at the bridge as shards of Miles’ horn float through the wreckage of Parliament.

19:10: Miles Davis: What If
From one deep funk track to another, but dear god is this heavy. Previously unreleased track from Panthalassa, I edited it out of Laswell’s mix of Black satin/What if/Agharta prelude dub. It was called What If by Laswell because we was wondering, “what if this is Pete Cosey (on lead guitar?)”, but actually it’s Maclauglin. The real star is Michael Hendeson’s bass line, an awesomely solid, endlessly repeating syncopated figure that’s just irresistible. This one just rocks.

22:44: Curtis Mayfield: Stone Junkie (Live)
The marvellous Curtis in cheeky mood from this seminal soul live album, recorded at the
Greenwich Village‘s Bitter End club on a freezing January ’71 night and released on the brilliant Curtis/Live! Album. Stone Junkie calms it down a bit from What If, but the chill factor is back with the FX. This is the sort of soul Miles was listening to pretty relentlessly throughout the seventies.

28:28: Miles Davis: Billy Preston
Another fantastic heavy funk work out, this is from the 1974 sessions that yielded the Get Up With It album. Most critics don’t seem to like this one but I love it, so much so I did a remix of it. This is just a dub of the original.

33:51: Headhunters: God Made Me Funky (Edit)
This is thee archetypal fusion track, here ripped to fuck. Herbie Hancock famously went looking for a bit of earth in 1973 and put together a funk band, The Headhunters. Yes it’s from the largest-selling jazz album of all time, but here’s it’s had the wanky sax solo ripped out, which makes the lush, faded out funk heaviosity that much more effective.

39:21: Miles Davis: Black Satin
From On The Corner – Kode 9’s favourite album of all time – and it’s a corker! Black Satin is built around a spanking hot cyclical break from Jack DeJohnette, with a set of discordant counter point tones bouncing around it and shimmering fuzz guitar drifting from the shadows.

43:14: Miles Davis: Bitches Brew (Edit)
This track is just mental. Absolutely dead serious, utter funk badness and jazz freakiness. This is just total, wailing madness which stays utterly the right side of formlessness, the energy surges and crackles and frankly it’s terrifying. The original edit loses its focus (sacrilegious though it is to say it) so I sharpened it up quite a lot by keeping the spotlight firmly on Miles – which doesn’t fit into the commonplace revisionism of praising the sidemen, but this is really about going with Davis into the nightmare. Across the chasm.

46:59: Miles Davis: In A Silent Way / Shhh Peaceful (Bill Laswell dub)
You simply don’t get any higher – or darker – than Bitches Brew, so it was time to let some light in with some lovely, twisted, sardonic chillage from 1969’s fantastic In A Silent Way album. If you’re reading this before downloading the mix and wondering if it’s all going to be a bit too much like onanistic jazz freakery, then fast forward to this bit cos it’s just lovely. Literally everyone in the country should own a copy of this album and we’d all be happier for it. And – despite the virtuosity on display throughout the rest of this mix, this is the one tune that absolutely anyone can learn to play on the guitar in half an hour. It’s that simple. But what Miles and his band do with it here is just priceless.

54:49: Curtis Mayfield: I Plan To Stay a Believer (Live)
Another one from Curtis / Live, and what a fantastic song this is. I won’t drizzle it with clichés (for once) but this simple, direct soul is the ideal partner for In A Silent Way, a similar cleanser.

57:30: Miles Davis: It’s About That Time
But Miles, even after his astonishing displays of malevolence throughout this mix, can out-do Mayfield when it comes to conveying purity and innocence, as he does on the very brief It’ About That Time.

That’s it. be interesting to see what Paul Nomos makes of this one!
