Solar that doesn’t require direct sunlight:

[G24i] uses nano-sized titanium crystals, which turn sunlight into electricity in a process similar to photosynthesis (the method plants use to store the energy from sunlight in sugars). Because G24i’s technology is more powerful than other solar cells, it does not need direct sunlight to generate electricity and can work even in rainy Wales.

The use of nanotechnology also makes the cells lighter, more powerful and more flexible. Because they aren’t made using silicon, which is in high demand, they are also relatively cheap to produce. Traditional solar cells are either mounted on glass or use brittle plastic, which can be easily damaged. The versatility of G24i cells means they can be carried around to charge mobile appliances or used in remote areas far from the electricity grid.

This, about co-owner and venture capitalist Bob Hertberg, is also interesting:

His conviction that climate change needs to be addressed is matched only by his belief that it is business and the profit motive that will drive change. Renewable Capital’s investments include wind farms in the UK, and Hertzberg sees big money to be made from green technology, even without subsidies. The role of rich countries, he argues, should be helping the developing world adopt “distributed generation” (local mini-generators, such as solar panels) through “green financing” such as carbon offsetting. “Developing nations have jumped over fixed-line phones to mobiles. If we are smart, we can help them jump over fixed infrastructure like big fossil fuel power stations and develop distributed generation.”
