					<description><![CDATA[We could be generating huge amounts of power from sewage. The process is fairly simple &#8212; just ferment sewage to produce a fuel called biogas. Biogas is almost entirely methane, and so is natural gas, so the two are essential interchangeable. The potential to produce biogas is almost entirely overlooked by most countries &#8212; except [&#8230;]]]></description>

					<description><![CDATA[A company called Ultra Motor has released a new electric bike called the A2B. This bike looks great &#8211; I like the functional, minimalist style. The A2B is designed for urban or suburban commutes. According to Ultra Motors, the A2B offers unassisted power on demand for up to 20 miles at a cruising speed of 20mph. [&#8230;]]]></description>
