Platinum is used as the catalyst in high quality fuel cells, and is largely the reason why they are expensive. So finding a rich source of platinum could help with future transportation what with our current dependence on oil. Combining the technology with decent solar power arrays to electrolyse sea water into hydrogen, that would be happy outcome in my opinion. Solar technology is improving.
Most residential properties could provide their own power needs if their roof tops were covered in solar cells. The cost is high, and the typical life expectancy of panels is 25 years. But at present time with current fuel prices, it is actually break even to invest in solar power. If fuel prices go up, (inevitably) you will be saving in the long term.
It might actually be better to build up your solar array slowly, say spend £1000 on a 1kWh/day system, which can adequately power your house lights -- lighting circuits on distribution boxes/fuseboxes are normally separate from wall outlets anyway, so it'd easy to install.
Next year, you might get another panel and run your TV on that, via a separate adapter.
Next year, you get a third panel and run your kettle on that.
And so on.
Actually, if you get more panels than you need, you can sell the excess electricity you produce back to your electricity supplier. It is done - and most companies are happy to buy it. So if the price rises above break even costs, you hedge your investment this way and can ensure yourself a long term profit.
It just takes guts to make that kind of initial outlay.
