Solar power is competitive now
Attackers of solar power tent to cite high prices for it not being competitive with coal and oil. But what does it really cost? The high prices often cited go up to 40 cents per kWh. A kWh (or kilo Watt hour) is enough power to light 10 x 100W lightbulbs for one hour. The... »

Space-age glasses to replace bifocals
Traditionally, people that need glasses for seeing close to them but not for seeing far away have had a problem.

Kia committing to Hydrogen-fuelled cars
In this site I’ve posted about more than one innovative and environment friendly method of creating hydrogen. But it wouldn’t be worth much without using using it to replace polluting and petrochemical-based devices. Cars are an excellent example. Kia Motors is committing to have 10′000 hydrogen vehicles on the street before 2015. The vehicles they... »
