I've had a brilliant idea
Why doesn't the government bung this company, say, £100bn of our electricity bills to fit a strip of these tiles along all of the railway lines in the country. Trains are big and heavy so they'll generate so much energy that they can power the trains with them! And have enough left to power some of those windmills polluting the countryside so they'll look nicer by spinning all the time!
When somebody works out induction charging for electric cars, they can do it on motorways too!
