Have Bananas Lost Their Mojo?

Written by Aimee Cremasco


Continued from page 1

Honduran scientists have peeled and sifted 400 tons of bananas in an effort to find seeds for breeding—they found 15 of them. Though it may not sound like many, scientists are developing a fungus-resistant variety that could be grown organically.

Sure, modern science may be able to save this fruit, but even if bananas survive thenext 10 years, chances are they will look and taste quite different.

Shedding Light on Cheaper Solar Energy

PV can helprepparttar environment by offsettingrepparttar 110127 need to rely on electricity generated fromrepparttar 110128 burning of fossil fuels. Two distinct systems now enteringrepparttar 110129 PV market are based onrepparttar 110130 use of cadmium telluride (CdTe) and copper indium gallium di-selenide (CIGS) materials in solar cells. The team at Sheffield Hallam University has increased our understanding of PV by showing how solar cells based on CdTe and CIGS structures work. Lack of knowledge in this area, combined with cost, has hinderedrepparttar 110131 widespread take-up ofrepparttar 110132 technology. Nowrepparttar 110133 team has opened uprepparttar 110134 prospect of new solar cells being developed commercially with higher conversion efficiencies than those currently available.

Dr I. M. Dharmadasa, who ledrepparttar 110135 research team says: 'We've already applied for two patents and are preparingrepparttar 110136 final draft ofrepparttar 110137 third patent in connection with our work, but there's a lot more science to be explored that could increase conversion efficiencies to over 20% inrepparttar 110138 near future'.

The research initiative, Low-cost, High-efficiency Thin-film Solar Cells with Electrodeposited Semiconductors, has received initial total Engineering and Physical Sciences Research Council funding of 104,632 and follow-up Sheffield Hallam University funding of 140,000. EPSRC isrepparttar 110139 UK's main agency for funding research in engineering andrepparttar 110140 physical sciences and invests more than 400 million a year in research and postgraduate training to helprepparttar 110141 nation handlerepparttar 110142 next generation of technological change.

With affordable energy provision remaining one ofrepparttar 110143 world's most urgent needs,repparttar 110144 advances being made in this area offer real hope for a future in which energy supplies are more widely available withoutrepparttar 110145 drawback of environmental damage.
