Dick Strawbridge on how it’s easy to be green

Top eco-warrior Dick Sytrawbridge addresses some of the common misconceptions about making your home low energy and eco-friendly.

4) Most eco-renovation take decades to pay back the cost

Every time we decide to make an investment in an eco-project, the subject of payback comes up. It is possible to do the sums, and before we spend any hard earned cash I like to make sure that it’s a good investment. For example, loft insulation can pay for itself in two winters, and with the 2010 feed-in tariff I would expect solar PV to pay for itself in about seven or eight years, and a DIY solar thermal system to heat your hot water should have paid for itself in four or five years. But surely this is missing the point: when it comes to environmentally friendly projects we seem unable to accept the fact that it can be an investment and will add to the value of the house. What is the payback time for a new bathroom or kitchen? If you install solar photovoltaic panels you can reasonably expect them to easily last 25 to 30 years. Everyone knows a new kitchen makes a house more saleable, but in the current economic climate, how much more saleable is a house that will cost the new owners very little to run or may even generate an income?

The 200mpg supercar

The Velozzi is a concept car promising supercar performance- 0 to 60 in 3 seconds and a 200mph top speed- with 200mpg fuel consumption. It achieves this by recharging its batteries with a micro-turbine which can use any “heavy fuel”- such as gasoline, ethanol, methanol, diesel or bio diesel. It’s also super light, being built out of composites and liquid metal.

The research and development company behind the concept wanted to produce the most spectacular demonstration of the technology possible. The use of a turbine to charge the batteries means the car isn’t tied to electrical supply points and the versatility of teh fuels means it can use the existing petrol infrastructure. Everyday production vehicles are going to be heavier and less efficient, obviously, but still a vast improvement on current motorcars.
