In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine.

...

Combined with another catalyst, such as platinum, that can produce hydrogen gas from water, the system can duplicate the water splitting reaction that occurs during photosynthesis.

Yes, but that's the rub. What other catalyst aside from Pt is acceptable? MIT isn't releasing the white paper on this just yet.

Hasnt tellurium been the unnoticed for solar and such? Blu ray technology and so forth?

Metal alloys

It is mostly used in alloys with other metals. It is added to lead to improve its strength and durability, and to decrease the corrosive action of sulfuric acid.
When added to stainless steel and copper it makes these metals more workable. It is alloyed into cast iron for chill control.
Other uses:

Used in ceramics.

It is used in chalcogenide glasses.

Tellurium is used in blasting caps

Organic tellurides have been employed as initiators for living radical polymerisation and electron-rich mono- and di-tellurides possess antioxidant activity.

High purity metalorganics of both selenium and tellurium are used in the semiconductor industry, and are prepared by adduct purification.

Semiconductor and electronic industry uses:

Tellurium is used in the media layer of several types of rewritable optical discs, including ReWritable Compact Discs (CD-RW), ReWritable Digital Video Discs (DVD-RW) and ReWritable Blu-ray Discs.

Tellurium is used in the new phase change memory chips developed by Intel.

Bismuth telluride (Bi2Te3) is used in thermoelectric devices.

Tellurium is used in cadmium telluride (CdTe) solar panels. NREL lab tests using this material achieved some of the highest efficiencies for solar cell electric power generation. First Solar Inc. started massive commercial production of CdTe solar panels in recent years, significantly increased tellurium demand. If some of the cadmium in CdTe is replaced by zinc then CdZnTe is formed which is used in solid-state x-ray detectors.

Alloyed with both cadmium and mercury, to form mercury cadmium telluride, an infrared sensitive semiconductor material is formed. Organotellurium compounds such as dimethyl telluride, diethyl telluride, diisopropyl telluride, diallyl telluride and methyl allyl telluride are used as precursors for MOVPE growth of II-VI compound semiconductors. Diisopropyl telluride (DIPTe) is employed as the preferred precursor for achieving the low temperature growth of CdHgTe by MOVPE.

and it's in VERY short supply.:D

Just for an add on... check their stock for the last 2 years. :)

NASDAQ:FSLR

This will be the next bubble i am guessing. More then likely you will find some easy money to make riding these type of companies for a short time.
