Dr. Danny Petrasek is trying to answer that question. Currently on the research and teaching faculty in Bioengineering and Applied and Computational Mathematics at Caltech and the clinical faculty at the UCLA School of Medicine, Petrasek is uniquely positioned at the intersection of biology, physics, and engineering to determine what the future might look like. And as a Venture Partner at Voltage Capital, he?s putting his money where his mouth is. ?Betting on the solutions to our energy shortcomings is the goal of every

green tech investor,? he says. ?But in truth we have no idea where to solutions will come from. It?s a constant search that will see many failures before an explosive breakthrough.?
Petrasek?s search to hedge the bet is three fold. Given the unknowns, what are the most commercially viable products and services? Where are the hotbeds of research? And where have breakthroughs occurred but not been commercialized?
One of the

largest sectors within clean tech and one of Petrasek?s specialties is

solar energy. Photovoltaic technology is proven but ineffi cient
hogan outlet
and expensive, so strong contenders for investment are companies and technologies who are figuring out the storage problem (i.e. batteries) and making the supply side cheaper.
A key ingredient to solar cells are silicon wafers. Once the lone domain to computer companies for use in microchips, silicon is now a commodity in great demand for green tech. "Make the wafers cheaper," Petrasek says, ?and the solar energy product becomes cheaper. We are never

going to get the kind of explosion as we got in computer chips, but
giubbotti peuterey
what we will see is the silicon wafers and solar cells

getting cheaper and cheaper. Right now the price of silicon is rising, so one prospect of investment lies within synthetic silicon production."
More companies producing silicon means cheaper chips, which in turn means cheaper solar cells, but that doesn?t address the biggest obstacle, storage. Collecting the energy is one thing, but once solar energy is absorbed and processed into electricity, you need to store it somewhere. There is no control over when the sun shines and at present there is no perfect solution to storage - today's batteries simply cannot keep up with the power or lifestyle demands of society. "Once we solve the storage problem," Petrasek says, "then

you will see an explosion in solar energy. Until that time, its still not a great resource."
The solar energy industry is poised for a breakthrough, but
mulberry sale
as with so many new technologies, it is at the mercy of the market. When the economy was strong and new construction booming, solar gained market share, but all that ceased with the real estate crash. Prices are still too high for widespread implementation even with government subsidies, but if Congress adopts a carbon cap or
nike air jordan pas cher
begins selling emissions credits?both of which appear likely to happen in one form or another in the coming years?than solar will again be on the precipice of success. "Solar and storage is still an open field," says Mouli Cohen, Founder of Voltage Capital, "but we don't know what the future holds. As investors, we
hollister sale
have to look at everything going on and try to

decide where go. At Voltage, we?re still answering that question, but we need to begin moving soon."

Temat postu: hogan outlet Treize ans de rapports inégaux Hum
En fait, les accords reflètent l'agenda européen : lutte contre le terrorisme, lutte contre l'immigration, ouverture des [url=http://www.rivaluta.it/hot/hogan.asp]hogan outlet[/url] marchés. Ainsi, en 2000, se félicite un rapport de la commission, les [url=http://www.sandvikfw.net/shopuk.php]hollister sale[/url] pays de la Méditerranée ? avaient le plus haut niveau de protection dans le monde ?. Il n'en est plus [url=http://www.getconversational.com]hollister france[/url] de même aujourd'hui : les accords d'association signés en 2006 ont conduit [url=http://www.vivid-host.com/barbour.htm]barbour uk outlet[/url] à [url=http://www.achbanker.com/home.php]hollister[/url] un [url=http://www.eracorrect.com]mulberry outlet[/url] démantèlement des droits de douane pour les produits industriels, et la libéralisation du marché agricole avance. S'il est de bon ton d'expliquer [url=http://www.eracorrect.com]mulberry sale[/url] que le libre-échange repose sur le principe du gagnant gagnant, la réalité est autre. La balance commerciale en 2007 montre que c'est l'UE qui remporte [url=http://www.1855sacramento.com/peuterey.php]giubbotti peuterey[/url] la mise, avec [url=http://www.getconversational.com]hollister pas cher[/url] un bénéfice commercial de 7 %. Le montant des exportations de l'UE en direction des pays méditerranéens est de 120 milliards d'euros, soit 9,7 % des [url=http://www.msc-sahc.org/moncler.asp]moncler doudoune[/url] exportations de l'Union européenne. Les importations venant [url=http://www.mansmanifesto.com]doudoune moncler[/url] de ces mêmes pays ne comptent que pour 107 milliards et ne représentent que 7,5 % des importations de l'UE.
Il y a trois ans, lors de la conférence de Barcelone, seuls les ?tats de l'Union européenne (UE) avaient signé à l'occasion du 10e anniversaire du processus la déclaration ? Vision commune pour le sommet euroméditerranéen ?. La faute en revenait aux divergences sur la situation au Proche-Orient. Le [url=http://www.rtnagel.com/louboutin.php]louboutin pas cher[/url] principe de deux poids deux mesures imposé par l'UE dans ses demandes de respect du droit international à Isra?l et aux autres pays de la région irrite, et le conflit au Proche-Orient cristallise l'incompréhension entre les deux rives.
Le prédécesseur de l'Union pour la Méditerranée, le processus de Barcelone, a échoué pour avoir répondu avant tout aux intérêts des entreprises du Nord.
