It’s possible to order from our website and have the book delivered to your home. If you don’t want to pay delivery costs, you can ask our staff at the Customer Service Desk to order one for you. They will then fill out a request form for you and notify you once the book arrives, so they’ll need a number where you can easily be reached. If we already have the book in our central warehouse, you should be able to pick it up in a day or two. Otherwise, it’s likely to take a week.

Is iron the fuel of the future? According to scientist Jeffrey Bergthorson, iron can be turned into iron powder and then burned to provide clean energy. The process used to produce iron powder requires large amounts of electricity, but it could be done in deserts where sunlight could provide solar power. The iron powder could then be shipped wherever it is needed. Iron powder does not require special modes of transportation or storage facilities. This would be an advantage over fuels such as hydrogen, which can be dangerous to transport.
Bergthorson has shown that his idea is technically possible and would not pollute the air because burning iron produces no CO2. He is now working on the next step- building an engine that can actually do the burning. If he is successful, such a device could be used to power large ships or even space rockets.
