Solar is only of use in daylight, and even more restricted by time of year, location etc. We need to work on wind energy in a similar way. Holes through buildings, particularly tall ones, can power fans. Small wind generators on sides and edges of tall buildings. In towns, huge propellers are too risky and noisy. Ventilated air and waste water needs to have heat extracted and recycled. Better wall and window insulation will reduce need for heating and cooling. Heat pumps extracting heat from air, water or soil can increase efficiency of heating and cooling. Efficient storage of heat (water or salt) can be used by individual buildings or neighbourhoods, to spread warmth to colder parts of the day/night cycle.

There is a similar project being conducted at Swansea University here in the UK.

Changes in the economy is making solar more affordable. Pricing has dropped a good bit on solar modules. Combine that with your tax credits, solar is finally more affordable for your average household.

Well, we need a real cheap “solar-paint”, that everybody can paint onto alufoil or graphite paper electrodes. This way the revolution will come from homemade VERY CHEAP solar cells. How long should we still wait, until the companies will ship their still too expensive solarcells ?

Naeem, Solar Power works & is in use much more than you must realize. Here in VT, it is growing by leaps & bounds, not just be residents, such as myself being 100% solar powered, but also by big companies such as NRG Systems – just look at their website. Green mountain Power has a huge solar system & Green Mountain Coffee Roasters is about to install the biggest system in the state, Farmway,in Bradford is now 40% solar powered…. An area the size of the Nevada test site & Nellis AFB could deliver twice the needed energy to meet the entire U.S. needs, using today’s existing photovoltaic technology!

The current tax incentives, federal & local combined, make it affordable for so many!

Nice and informative.. looks like a research going on in right direction… a technology both viable and beneficial!!!

But The astonishing fact, given at the end: “presently the global market for solar cells is growing at a faster rate than markets for mobile phones, digital cameras and laptops.”

Is it really so? seems quite unbelievable; as Solar technology, in spite of its undeniable potential, is yet to come of age. Cost efficiency is still a BIG Question mark, in Solar Cell Technology.
